In Lampung Province, awareness of the importance of forest health in achieving sustainable forest management in various types of forests is still low so that forest health problems have not received serious attention so far. This study aims to obtain indicators of forest health assessment and the status of forest health conditions in various types of forests in Lampung Province. This research was carried out in mangrove and community forests in East Lampung District, and protected and conservation forests in Tanggamus District in 2018. The stages of this study consisted of formulating guarantees of forest health indicators, making measuring plots, measuring forest health, processing data, and forest health assessment. The results showed that indicators for assessing the health of forests in mangrove forests are vitality and biodiversity, in community forests are productivity, vitality and site quality, in protected forests are biodiversity, vitality and productivity, and in conservation forests are biodiversity and productivity. The status of health conditions in each cluster of plots in mangrove forest is bad and good, in community forests is good and medium, in protected forests is bad and good, and in conservation forests are bad and good.Keywords: indicator, forest health status, forest types, Lampung Province

Conservation forests must maintain the function and quality of their forests so that the preservation of the living natural resources therein is not damaged and the balance of the ecosystem is well ordered. The benefits of a conservation forest can be felt by the people who live around the forest such as carbon, water sources, non-timber forest products so that the community can prosper. Forest health monitoring is an activity designed to monitor the condition of forest health based on the results of measurable ecological indicators for forest management decision making. The purpose of this study is to determine the value of conservation forest health status and identify internal and external factors of conservation forest health. The method used is Forest Health Monitoring for assessing forest health status and Statistical Product and Service Solutions 20. software for determining the relationship of internal factors with external forest health. The results showed the health status of the conservation forest included in the management area of the Sustainable Peoples Forest System Farmer Group in the Teluk Pandan sub-district of Pesawaran District included in the medium category (3,20) . Internal factors that affect the health of conservation forests are biodiversity and tree damage while external factors that affect the health of conservation forests are the level of farmers' knowledge, farmer participation and farmer motivation.

Full textAbstract:
This paper presents the current results of a continuing survey of the distribution, status and biological importance of Tanzanian coastal forests. The Frontier-Tanzania Coastal Forest Research Programme has shown that at least 34 locations, and possibly another eight, support important coastal forests. There are probably 350–500 sq km of forest remaining, with most sites smaller than 20 sq km. Most sites, and 75–85 per cent of the total area, are located in Forest Reserves. Coastal forest supports many endemic taxa and many individual forests support species and subspecies known from nowhere else. All these forests are severely threatened and effective conservation action is a priority. The Frontier-Tanzania project findings are contributing to conservation programmes co-ordinated by the Wildlife Conservation Society of Tanzania and the World Wide Fund for Nature (Tanzania).

SummaryThe Hainan Hill-partridge Arborophila ardens is endemic to the island of Hainan, which lies off the south coast of China. Distinct subspecies of the Silver Pheasant Lophura nyethemera xvhiteheadi and Grey Peacock-pheasant Polyplectron bicalcaratum katsumatae are also endemic to the island. All three taxa are considered endangered and are very poorly known in the wild. Surveys of remaining patches of forest were undertaken between 1987 and 1994 during which local people were interviewed and some forest areas were visited. The hill-partridge was confirmed from three blocks of forest and reported from a further four. The Silver Pheasant was found in six areas of forest and probably occurs in all remaining patches of well-developed secondary and primary forest. The Grey Peacock-pheasant was recorded in five forests and reported from a further four. The hill-partridge was more restricted in its habitat use than the other two species, the latter using well-developed secondary forest in addition to primary forests. Provisional density estimates made at Ba Wang Ling National Nature Reserve were 6–8 Hainan Hill-partridges/km2, 7.5 Silver Pheasants/km2 and 3.75 Grey Peacock-pheasants/km2.

SummaryFour weeks of fieldwork in the forests of Mindoro, Philippines, in 1991 has elucidated the status of the six bird species endemic to the island. Of these, Ducula mindorensis and Otus mindorensis are high-altitude species with restricted ranges and in need of active conservation in the medium term. Three of the four lowland species, Gallicolumba platenae, Centropus steerü and Penelopides mindorensis are under immediate threat of extinction through forest clearance and fragmentation, while the fourth, Dicaeum retrocinctum, s i not under immediate threat but is certainly at risk of extinction in the long term. Whilst deforestation is an enormous problem across the entire Philippines, Mindoro is the smallest centre of endemism with the least forest cover after the Sulu Islands. Extinctions are believed inevitable within the next 10 years unless concerted action is urgently taken. The Halcon range must receive attention in order to conserve the montane species, but more urgent by far is the preservation of lowland forest remnants, concentrating on central-west Mindoro.

Full textAbstract:
Abstract The paper summarizes current knowledge on the population size, habitat, conservation status and conservation measures for the White-backed Woodpecker Dendrocopos leucotos in Slovenia. The species is an extremely rare forest specialist species. It inhabits mostly Dinaric beech Fagus sylvatica forests from Trnovski gozd, Nanos, Javorniki Mts and Mt Snežnik to the Kočevsko region and Gorjanci Mts. The species is also present in the Zasavje region and Mt Boč. The majority of the population (80%) inhabits the altitudinal belt between 700 and 1400 m a.s.l. The size of the Slovenian breeding population is currently estimated at 100-150 breeding pairs. Using the new survey playback method, we expect to find the species at additional sites. The highest densities were recorded on Mt Snežnik (0.7 breeding pairs/km2 in the Zatrep - Planinc forest reserve, 0.6 breeding pairs/km2 at Gomance) and in the Gorjanci Mts (0.6-0.9 breeding pairs/km2 in the Kobile forest reserve). The species inhabits beech and mixed forests with an important percentage of dead trees. The volume of dead trees was measured only at few sites inhabited by the species and ranged from 42 to 283 m3/ha. Signs of foraging were detected mainly on beech snags and stumps; all nests were found in upright beech snags. In Slovenia, the species is threatened by the low percentage of dead deciduous trees in forests, the construction of new forest roads, the increased annual timber harvest and a weak network of forest reserves. The proposed conservation measures include increasing the amount of dead deciduous trees in managed forests, increasing the area of forest reserves and halting the construction of new forest roads.

SummaryThe forests of the Taita Hills of south-east Kenya are of great importance to conservation, holding three endemic birds and many other endemic taxa. We surveyed birds in their remaining forest fragments in July-August 1996, and followed up these surveys with collection of remote sensing imagery of the area, an assessment of museum specimens and a thorough literature review. In this paper we assess the conservation status in the Taita Hills of their 47 species of forest birds. We conclude with general recommendations for the conservation of the area.

Full textAbstract:
The nearly ubiquitous bottomland hardwood forests that historically dominated the Mississippi Alluvial Valley have been greatly reduced in area. In addition, changes in hydrology and forest management have altered the structure and composition of the remaining forests. To ameliorate the detrimental impact of these changes on silvicolous wildlife, conservation plans have emphasized restoration and reforestation to increase the area of interior (core) forest habitat, while presuming negligible loss of extant forest in this ecoregion. We assessed the conservation–protection status of land within the Mississippi Alluvial Valley because without protection, existing forests are subject to conversion to other uses. We found that only 10% of total land area was currently protected, although 28% of extant forest was in the current conservation estate. For forest patches, we prioritized their need for additional conservation–protection based on benefits to forest bird conservation afforded by forest patch area, geographic location, and hydrologic condition. Based on these criteria, we found that 4712 forest patches warranted conservation–protection, but only 109 of these forest patches met our desired conservation threshold of >2000 ha of core forest that was >250 m from an edge. Overall, 35% of the area of forest patches warranting conservation–protection was protected within the conservation estate. Even so, for those forest patches identified as most in need of conservation–protection, less than 10% of their area was currently protected. The conservation–protection priorities described fill an unmet need for land trusts and other conservation partners pursuing strategic forest protection in support of established bird conservation objectives.

Full textAbstract:
SummaryWe report the current status of birds at the Namuli Massif, northern Mozambique. Despite being the only known locality for the Namuli Apalis Apalis lynesi and the nominate race of the Dapplethroat Arcanator orostruthus, the mountain is very little known ornithologically. Prior to our survey it had only been visited by an ornithologist in 1932, when Jack Vincent collected in the area for three weeks. During our week-long survey in November-December 1998 we recorded 130 bird species from the Namuli area, including all three globally threatened species reported by Vincent (Thyolo Alethe Alethe choloensis, Dapplethroat and Namuli Apalis). The higher-elevation (>1,500 m) forests are still largely intact, but most of those at lower elevations have been cleared for agriculture. The alethe and apalis are common, occurring in remnant forest patches and secondary scrub as well as pristine forest from 1,160 to 2,000 m. The Dapplethroat is restricted to large, intact forests above 1,500 m, but also is fairly common (up to 2–3 singing males per hectare; greater densities than recorded elsewhere). Red-rumped Swallow Hirundo daurica was recorded for the first time in Mozambique, and was suspected of breeding at 1,400 m. We estimate that some 1,300 ha of pristine forest remains on the main massif between Gurue and Mount Namuli, but this area is being reduced by burning and “subsistence” logging. Approximately 7,000 people currently live in the area east of the main forest. Grazing by goats and pigs on the montane grasslands surrounding the forests is another problem, but the gravest threat is posed by improved road access to the area, which could open the forests to commercial logging. In addition to being the sole locality known for the Namuli Apalis and the nominate race of Dapplethroat, the Namuli forests probably support the largest single populations of Thyolo Alethe and the well-marked belcheri race of Green Barbet. These populations make Namuli arguably the most critical Important Bird Area for Mozambique, and the remaining forests have a high priority for conservation action.

Full textAbstract:
Due to limited financial and technical resources, there is a pressing need to identify priority areas and strategies for conservation globally. This study aims to prioritize important forest areas for conservation on the island of Malaita, Solomon Islands. Five different forest types were sampled to quantify biodiversity using the species richness of frogs and lizards (herpetofauna) as a biological indicator of conservation status. Unlogged coastal, unlogged lowland and unlogged upland forests have minimal disturbance whereas logged lowland forests and plantation teak forests are heavily disturbed. Subsequently, the effects of human modification on forest systems are also quantified based on anthropogenic disturbance. Interviews with local community members were conducted to gather associated local traditional knowledge on the cultural importance of frogs, lizards and forest habitats. Prioritization methods based on species richness, species uniqueness, cultural importance and threatened status are used to identify key forest areas. The four main results found are: 1) unlogged lowland forests have the greatest biodiversity value, 2) unlogged lowland forests also have the highest cultural value based on local uses, 3) logged lowland forests are biologically important, and 4) unlogged coastal forests and unlogged lowland forests are under the greatest threat from anthropogenic activities. Based on these results, the conservation of unlogged lowland forests on Malaita should be prioritized. These results also highlight the importance of combining biological sampling with cultural information to improve the efficiency and long-term success of conservation actions.

Full textAbstract:
SummaryThe forest-associated Yellow-throated Apalis Apalis flavigularis is the only bird endemic to Malawi. The species is confined to three mountain massifs in the south of the country and is classified as globally ‘Endangered’. This study re-evaluates its conservation status by assessing its population size and habitat preferences on Mount Mulanje, where forest patches are threatened by illegal logging and an increasing frequency of uncontrolled fires. These fires also cause a proliferation of invasive plant species, especially the Himalayan yellow raspberry Rubus ellipticus. We surveyed the Yellow-throated Apalis in 41 forest patches during the breeding season. The apalises favoured forest edge habitat, occurring in forest patches as small as 0.01 ha. Their occurrence was positively correlated with the presence of R. ellipticus, although this relationship may be driven primarily by canopy architecture and the existence of an understorey shrub layer. At a conservative estimate, 7,900 Yellow-throated Apalises were calculated to be present in cedar forest habitat alone on Mount Mulanje. Given that the birds occurred in other native forests at the same altitude at densities of 8.6–10.9 birds ha-1, the true population size on Mount Mulanje alone is likely to approach or even exceed IUCN’s most optimistic estimate of the global population (10,000).

AbstractThe natural range of variation of ecosystems provides reference conditions for sustainable management and biodiversity conservation. We review how the understanding of natural reference conditions of boreal forests in northern Europe has changed from earlier perceptions of even-aged dynamics driven by stand-replacing disturbances towards current understanding highlighting the role of non-stand-replacing disturbances and the resultant complex forest dynamics and structures. We show how earlier views and conceptual models of forest disturbance dynamics, including the influential ASIO model, provide estimates of reference conditions that are outside the natural range of variation. Based on a research synthesis, we present a revised forest reference model incorporating the observed complexity of ecosystem dynamics and the prevalence of old forests. Finally, we outline a management model and demonstrate its use in forest ecosystem management and show how regional conservation area needs can be estimated. We conclude that attaining favourable conservation status in northern Europe’s boreal forests requires increasing emphasis on ecosystem management and conservation for old forest characteristics.

Full textAbstract:
Biodiversity is a concept covering all levels of biological organization, including genes, species, and ecosystems. Few estimates of levels of biodiversity in Canadian forests have been made. It is likely that, in general, species and ecosystem diversity do not match those in forests of more southerly latitudes, but genetic diversity is probably comparable. Although conservation activities both within and outside the natural surroundings of a species are already extensive, further efforts are justified and the effectiveness of current efforts should be demonstrated.The impact of human disturbances on forest biodiversity must be assessed. Inappropriate forest harvesting operations can lead to habitat fragmentation and loss of ecosystem integrity. Revision of forest management systems may be required to conserve biodiversity, but comprehensive and integrated research programmes must be developed in different forest regions to provide the necessary scientific information which is currently lacking.

Full textAbstract:
The objective of forest management in the tropics, in recent decades, has shifted from timber production to biodiversity conservation and maintenance of life support system. However, past forestry practices have greatly influenced the structure of plant communities, preponderance of foreign invasive species, populations of high value medicinal plants as well as other non-wood forest products. We assessed the abundance and distribution of medicinal plants in managed and undisturbed forests of Dehradun Forest Division (DFD), Uttarakhand (India). A total of 80 transects (each 1 km long) were laid in various categories of forest types in DFD. This paper deals with distribution, availability and regeneration status of five commercially important species viz., Justicia adhatoda, Aegle marmelos, Phyllanthus emblica, Terminalia bellirica and Terminalia chebula, across different forest types. The study reveals that open canopy forest patches, Lantana infested patches and Acacia catechu-Dalbergia sissoo (Khair -Shisam) woodlands in the eastern part of the DFD have excellent potential for the production and sustainable harvest of Justicia adhatoda. Areas those are less suitable for timber production viz., open hill forests, have greater potential for conservation and development of Aegle marmelos, Phyllanthus emblica and Terminalia bellirica. For the production and management of high value medicinal plants in the DFD these ecological considerations need to be kept in mind.

Full textAbstract:
SummaryThe largely deforested island of Cebu, Philippines, hosts a forest-dwelling hawk-owl identified in the literature as Ninox philippensis spilonota but which is in fact a Cebu island endemic species, soon to be named. To determine the current distribution and habitat requirements of this hawk-owl, the five largest of 11 remaining forest patches on Cebu were surveyed between March and June 2011, involving 64 post-sunset 500-m walked transects with playback and habitat assessments. Radio-telemetry studies were also conducted on 10 owls but only for 3–5 days per owl as they removed the transmitters. A total of 52 owls were located across all five forests (at 16 sites two owls responded together to playback) but only the largest forest, Alcoy, contained enough transects for analyses of habitat in relation to owl distribution. Alcoy stands on steep-sided hills and some planting of exotic species occurs within it. Owls were detected in forest interior, forest edge and forest-plantation mix in Alcoy, and on ridges and in gullies despite lower tree densities and greater proximity to clearings in the gullies. However, parts of Alcoy experience strong winds, and owl occupancy decreased significantly with increasing wind speed. Home ranges for the 10 radio-tagged owls were estimated to cover ∼10 ha, although given the short tracking periods this may be an underestimate. Suitable forest studied covers roughly 1,670 ha, with six unstudied forests totalling 250 ha, so assuming a pair every 10 ha would give a tentative global population estimate of ∼ 200 pairs of Cebu Hawk-owls, and even fewer if home ranges are larger than estimated. This, coupled with continuing habitat degradation, triggers the IUCN Red List category ‘Endangered’. Tree cavities suitable for nests may be limiting, and nest-box provision could be explored, provided this does not increase predator pressure on other rare species.

Full textAbstract:
We quantified habitat associations and evaluated the conservation status of a recently identified, undescribed species of dwarf chameleon, Bradypodion sp. nov. Dhlinza, endemic to scarp forest remnants in KwaZulu-Natal Province, South Africa. At the microhabitat scale the Dhlinza dwarf chameleon was found more often in forest gaps and near paths than highly disturbed edges or forest interior. Chameleon presence was not explained by forest physiognomic variables such as vine cover, shrub and tree density, or canopy cover. Presence near gaps may be better explained by the combined effects of the thermal microenvironment and food availability. The species is moderately common where it occurs, with estimated densities of 4.7, 8.7 and 29.7 individuals per ha within forest interior, edges and gaps respectively. At the landscape scale, the chameleon occurs only in three remnant forests: the Dhlinza, Entumeni and Ongoye Forests. The species' extent of occurrence was estimated to be 88 km2 and its area of occupancy 49 km2. Based on the small area of remaining suitable habitat, this species meets the requirements for categorization as Endangered according to IUCN Red List criteria.

Full textAbstract:
Analyzing the spatial extent and distribution of forest fires is essential for sustainable forest management. The present study appraises the distribution of forest fires in one of the largest states in India, Andhra Pradesh, using satellite remote sensing. Advanced Wide Field Sensor (AWiFS) onboard on Indian Remote Sensing Satellite (IRS P6) was used for mapping and analyzing the spatial extent of burnt areas. Comparative analysis was carried out with respect to different forest types, protected areas and across elevation zones to demarcate and identify the fire-affected areas. The results show that about 19% (8594 km2) of forest area were burnt in the state during 2009. Burnt area statistics for Protected Areas reveal that 24% of forest cover was affected by fire. Nagarjunasagar Srisailam Tiger Reserve, the largest tiger reserve of the country, shows an area of 793 km2 (22%) under forest fire. Higher elevation areas which are predominantly dominated by savannah and woodlands experienced higher fire occurrence in comparison with lower elevation areas. Similarly, fires were prevalent near edges compared to core forest. Results of the study suggested that forests of Andhra Pradesh are prone to high fire occurrences and current fire regime poses a severe conservation threat to biodiversity both within and outside the Protected Areas.

Full textAbstract:
The floristic study and the conservation value analysis of forest from the Jordan river middle basin are addressed in this research. This vegetation forms part of the subtropical mountain forests or Yungas, one of the most diverse ecosystems on Earth. Present forest species were surveyed, and the vegetation Interest Conservation index (INCON) was determined based on a series of conservation value criteria (Phytocenotic, Territorial, Mesological, Ethnobotanical, Perceptual and Didactics) recorded in the field. Available data on socio-cultural aspects of the area was also included in the study. All plants were identified up to genera and/or species. INCON was calculated from the sum of scoring assigned to each analyzed criterion. As a result, 42 forest species were identified; for each one, its conservation status was performed, including the altitudinal vegetation belt, biogeographical origin (at least for the genus), and their ethnobotanical value. The INCON obtained (135 points) showed the high natural, ethnocultural, landscape, and educational value of these forest vegetation according to the criteria analyzed. This information provides a useful tool to have a more precise knowledge of the diversity conservation status of Las Yungas. It also serves to recognize the biological and environmental relevance of this area, whose usefulness can be used for conservation purposes or decision making on protection plans.

Full textAbstract:
SummaryOrnithological surveys were conducted over a seven-week period on Taliabu, Sula Islands, Indonesia in 1991, concentrating on eight species (seven of which have restricted ranges) considered (in 1991) to be threatened and six species (two of which have restricted ranges) considered near-threatened. All of the restricted-range species are dependent on lowland forest, although most persist in secondary habitats, and some also occur in montane forest. Tyto nigrobrunnea was recorded for the first time since the type-specimen was collected in 1938, and is perhaps the most threatened of all the restricted-range birds. Megapodius bernsteinii, Pitta dohertyi, Rhinomyias colonus, Basilornis galeatus and Streptocitta albertinae are threatened in the longer term, primarily by habitat loss. Both Coracina schistacea and C. sula are able to persist in all but the most degraded of habitats. Of the two restricted-range species considered near-threatened, Zoothera erythronota is at greatest risk on Taliabu, apparently restricted to lowland forests. The other, Ptilinopus subgularis, is common in lowland forest and also occurs in montane forest. Little primary lowland forest was found in the areas visited on the island, and identifying remaining areas of this forest type and its relative importance to the birds, especially restricted-range species, should be given highest priority in further surveys. The suitability of a proposed reserve area on the island was evaluated: a larger area of lowland forest than is currently proposed should be afforded protection in order to safeguard the island's characteristic avifauna.

Full textAbstract:
While forests’ contribution to rural livelihoods has been unearthed scientifically, the patterns, determinants and forest conservation policy implications of livelihood diversification still beg for more scientific and policy edification. This paper makes a contribution in this regard, using household data (N = 200) from eight villages around the Kilum-Ijim Forest Landscape of Cameroon. The ordinary least square and the logit model are used to explore the determinants of livelihood diversification and the likelihood of forest dependence, respectively. The diversification patterns were analysed using a simple t-test, and the multinomial logit for conservation choices. We find that forest-related activities are a source of livelihood diversification for 63% of households, with non-timber forest products (NTFP) domestication (31%) and medicinal plant extraction (30%) being the most preferred. For non-forest activities, migration is the most preferred diversification strategy. Generally, households with favourable socio-economic status prefer non-forest to forest activities for livelihood diversification. The regression estimates indicate that older respondents are more likely to depend on the forest than the young, whereas males and individuals with at least some secondary education are less likely than their respective counterparts to rely on the forest. The results also suggest those who participated in training, educated household heads and older individuals are significantly more likely to choose high-valued diversification strategies. Concerning conservation activities, households with favourable socio-economic status are on average less likely to adopt NTFP domestication and more likely to adopt bee-keeping as a conservation choice. The results suggest the need for policy considerations to: (i) effectively integrate women in forest management processes, (ii) intensify trainings for conservation-friendly diversification approaches, (iii) regulate unclean energy use and (iv) encourage value chain improvement for conservation-friendly products.

SummaryThe critically endangered Sichuan Hill-partridge Arborophila rufipectus occupies a restricted range in south-central China. Field surveys within this range were undertaken using line transects in 1996 and 1997. Calling males were recorded from nine subtropical forest tracts within an area totalling 1,793 km2 and consisting of primary, natural secondary and replanted broadleaf forest between 1,100 and 2,235 m elevation. The only sightings obtained were in primary forest. The mean density of calling males estimated from data collected during transect surveys was 0.48 ± 0.06 and 0.24 ± 0.16 calling birds km−2 in 1996 and 1997 respectively. There was no difference in density estimates for calling males between primary forest and secondary/replanted broadleaf forest. The principal threat to the continued survival of the species is clear-felling of primary forest, but clear-felled areas are often replanted with native broadleaf trees and records of Sichuan Hill-partridge calls in such plantations offers hope for its future survival. Forest management should be modified to make forestry practices more sympathetic to the conservation of the Sichuan Hill-partridge.

The striped hyena is one of the least studied large carnivores in Nepal. We evaluated status of Striped hyena (Hyaena hyaena Linnaeus, 1758) and their conservation approaches in Rautahat and Sarlahi forests, Nepal. The overall objective of this study was to explore the baseline information on striped hyena and to recommend the future conservation action for striped hyena. Camera trapping, sign transect and questionnaire surveys were used to collect the baseline information on striped hyena. A total of 20 mammalian species including striped hyena were recorded. The striped hyena preferred riverbed than that of mixed forest, Accacia forest, Shorea forest and grassland. Most of the striped hyena sign evidences (36.27 %) were located in riverbed, followed by mixed forest (26.47%), Accacia forest (20.58 %), Shorea forest (15.56 %) and grassland (0.98%). Habitat degradation was one of the major threats to this animal and its prey species. J. Nat. Hist. Mus. Vol. 29, 2015, Page: 49-59

SummaryIn July and August 1994, we surveyed two areas in the south of the Cordillera de Colán, Amazonas department, Peru, above the north bank of the río Utcubamba. We found a high rate of deforestation, with trees being felled for timber, forest being cleared for the cultivation of cash crops, and elfin forest being burned for pasture. Most of the forest on the mountain range may have been cleared in 10 years. We recorded a number of important bird species, highlighting the significance of the area for the conservation of biodiversity; globally threatened birds included Peruvian Pigeon Columba oenops, Military Macaw Ara militaris and Royal Sunangel Heliangelus regalis. Elfin forest is under particular threat in the area, but probably still holds species such as Long-whiskered Owlet Xenoglaux loweryi. We recommend that a protected area containing areas of cloud-forest and elfin forest be established on the Cordillera de Colán.

<span lang="EN">Nowadays human impact to habitats and species are stronger then ever before. Latvia is typical example of fragmented landscape, where forest patches are mixed with agricultural land and waterbodies. Latgale is one of typical such a fragmented landscape parts of Latvia. Around 6.41 % of Latgalian forests were evaluated as Woodland Key Habitats (WKHs) or potential WKHs (P)WKHs after WKH inventory. In total 16 WKH types, suitable for bryophyte and lichen indicator species existence were identified in Latgale. (P)WKH type, forest stand age and area were significant factors influencing bryophyte and lichen specialist and indicator species richness in forest stand level. WKH status did not provide any official conservation status for habitats or species based on current legislation in Latvia. Therefore establishment of conservation areas as microreserves for habitats and species and Nature Reserves in areas, with high (P)WKH density is an effective tool for their long-term conservation in Latgale. Further scientific studies of bryophytes, lichens and WKHs are necessary for planning the best conservation scenarios taking into account also forest ecosystem services. </span>

Abstract Aims Tropical forests are increasingly threatened by edge effects as forest degradation and deforestation continues, compromising soil integrity, seedling regeneration capacity, and ecosystem services. Ninety-three percent of the last remaining forests of northern Ethiopia, which number 1022 in the South Gondar region of our study, are <16 ha and are protected because they have a Tewahido Orthodox Christian church at their center. The aim of this study was to determine the effects of human disturbance, forest size, distance from population center and other factors on the soil properties and nutrient status of sacred church forests. We also compared forest soil physical and chemical properties across land cover types in these forests. Methods We assessed the soil physical (water content and bulk density) and chemical (total carbon and nitrogen, available phosphorus, ammonium) properties of 40 sacred church forests across three spatial scales: within individual forests; among forests; and across land cover type (forest, forest edge-exterior, Eucalyptus plantation). We used distance from the edge within each forest to examine edge effects on soil nutrients. Results We found that nutrients and carbon decreased significantly from the interior to the outer edge of these forests and with forest size. Further, the soil of Eucalyptus plantations and areas outside of the forest were largely indistinguishable; both had significantly lower nutrient concentrations than sacred church forest soil. Conclusion Our research highlights the insidious impacts of edge effects and human disturbance on forest soils and the need for an integrated soil management program in the region that balances local needs with forest conservation. The conservation of these sacred church forests is important for maintaining regional soil nutrient status relative to agricultural lands and Eucalyptus plantations.

Full textAbstract:
Uttara Kannada is the only district in Karnataka, which has a forested area of about 80% and falls in the region of the Western Ghats. It is considered to be very resourceful in terms of abundant natural resources and constitutes an important district in Karnataka.The forest resources of the district are under pressure as a large portion of the forested area has been converted to non-forestry activities since independence owing to the increased demands from human and animal population resulting in the degradation of the forest ecosystem.This has led to poor productivity and regenerative capacity which is evident in the form of barren hill tops, etc. in Coastal taluks of Uttara Kannada , entailing regular monitoring of the forest resources very essential.The classification of forest is a prerequisite for managing forest resources.Geographical Information System (GIS),allows the spatial and temporal analysis of the features of interest, and helps in solving the problem of deforestation and associated environmental and ecological problems.Spatial and temporal tools such as GIS and remotely sensed data helps the planners and decision makers in evolving the sustainable strategies for management and conservation of natural resources. Uttara Kannada district was classified on the basis of the land-use using supervised hard classifiers.The land use categories identified were urban area, water bodies, agricultural land, forest cover, and waste land.Further classification was carried out on the basis of forest type. The types of forest categorized were semi-evergreen, evergreen, moist deciduous, dry deciduous, plantations and scrub, thorny and non-forested area. The identified classes were correlated with the ground data collected during field visits. The observed results were compared with the historic data and the changes in the forest cover were analyzed. From the assessment made it was clear that there has been a considerable degree of forest loss in certain areas of the district. It was also observed that plantations and social forests have increased drastically over the last fifteen years, and natural forests have declined.

Full textAbstract:
Diverse human pressures are degrading coastal forests with profound implications on invertebrate biodiversity. Butterfly species are key ecosystem indicators and their distribution may become a campaign tool towards conservation of specific habitats. However, a baseline survey of Dakatcha butterflies is long overdue, necessitating this study at A Rocha Dakatcha Nature Reserve (ARDNR) in Kilifi County. The objective was to identify Dakatcha butterfly species, their distribution, threats to the forest and conservation measures by the community in 2019. The modified pollard walk method was used to collect butterfly species from 21 transects from which the Shannon index of diversity, Margalef’s species richness index and evenness index were calculated. A total of 125 butterflies from five distinct vegetation types were captured and identified to represent 42 species and 25 genera from the documented 5 butterfly families in Kenya. Questionnaires were administered to twenty-nine community members on threats and conservation activities in ARDNR. The exercise confirmed that main threats to ARDNR butterfly habitat are agriculture, charcoal production from Diospyros corni and Dobera glabra and timber extraction from Manilkara mochisia, Brachystegia spiciformis, Thespesia danis and Brachylaena huillensis trees. The targeted deforestation of key tree species providing a suitable microclimate and an array of nectar sources to all threaten butterfly existence in the forest. Fortunately, there are five main stakeholders implementing diverse conservation projects including promotion of energy-saving jikos and beekeeping. In conclusion this study confirms existence of all five families of Kenyan butterflies in ARDNR. The presence of 13 butterfly species in the regenerating forest patch further affirming the importance of practical all-inclusive forest management and that community awareness enhances diversification of livelihood activities alongside sustainable forest utilization.

Himchari National Park (HNP) was declared as a Protected Area (PA) in 1980 under the section 23(II) of Bangladesh Wildlife Preservation Act 1974 of the Government of the People’s Republic of Bangladesh. The total area of the HNP is about 1,729 ha (4,271.15 acres) under the jurisdiction of Cox’s Bazar South Forest Division, Cox’s Bazar district. Once the forest was very rich in flora and fauna, but many of the species have disappeared due to habitat destruction, over-exploitation, habitat fragmentation, fire hazard, encroachment, indiscriminate harvesting of tree species and Non-Timber Forest products. The study was conducted through extensive whole area survey and quadrat survey methods. A total of 117 tree species (having ≥ 5 cm dbh) belonging to 37 families was recorded from the HNP. Moraceae family possesses the highest species (14) followed by Mimosaceae (8), Euphorbiaceae (7), Myrtaceae (6) and 5 species each by Anacardiaceae, Caesalpiniaceae, Meliaceae and Verbenaceae. A total of 69 tree species (59%) was found as Least Concern (LC) representing maximum tree species among all the categories. Vulnerable, Endangered, Near Threatened and Critically Endangered tree species were represented by 16 species (14%), 4 species (3%), 2 species (2%) and 2 species (2%), respectively. It is necessary to take effective measures for the protection, sustainable management, proper utilization and conservation of tree species in an aim to conserve the forest genetic resources of the Himchari natural forests.

Conservation of forest biodiversity is vital for mankind as it provides enormous benefits such as biological resources and ecosystem services. Of late, the forests are facing risk and threats such as fragmentation, degradation and forest fires which are responsible for the deteriorating condition. The progress in the field of science and technology like satellite remote sensing and GIS since the past few decades in India and the world provide an opportunity to track and monitor the changes taking place on the Earth’s surface. Besides, analysis of large spatial data in GIS can also provide insight into the various driving factors which lead to the loss of biodiversity in the threatened ecosystems i.e forests. This study has attempted to obtain information about the spatial extent of the three forest ecosystem degradation indicators viz. deforestation, fragmentation of forest and forest fires using methodical approach in the Jharkhand state of India. The satellite remote sensing data sets belonging to Landsat-8 were used to analyse the forest cover of Jharkhand state. To identify the areas of threat, grid cells (5KmX5Km) were generated in GIS domain. Analysis of deforestation was conducted using multi source data of the time periods 1935 and 2015. Evaluation of deforestation spanning over a time period reveals that vital changes have occurred in the forests of Jharkhand and determined 1224 extinct, 248 critically endangered, 318 endangered and 396 vulnerable ecosystem grid cells. The fragmentation analysis has determined 148 critically endangered, 296 endangered and 402 vulnerable ecosystem grid cells. Forest fire point’s data from the year 2005 to 2016 were utilized and analysis was executed. Further frequency of forest fires for each grid was noted. The result indicates that 67.3% of grid cell of Jharkhand forest was affected with forest fire. Conservation status has been evaluated based on the value of threat for each grid which was the fundamental criteria for conservation priority hotspot. About 2.1% of Jharkhand forest ecosystem grids are defined as extremely high ecosystem risk stage and have been designated in the category of conservation priority hotspot-1 followed by 19.7% conservation priority hotspot-2, 41.3% conservation priority hotspot-3, 27.8% conservation priority hotspot-4 and 9.1% lowest conservation priority hotspot-5. This study highlights the capability of integrating remote sensing and GIS data for mapping the forest degradation, which can be useful in formulating the strategies and policies for protection and conservation of forests.

Full textAbstract:
SummaryNew Britain in the Bismarck Archipelago of Papua New Guinea supports 14 endemic bird species and together with New Ireland, forms an Endemic Bird Area that supports 38 restricted range species. Extensive conversion of lowland forest to oil palm plantations resulted in the loss of over 20% of forest under 100 m altitude between 1989 and 2000. However the rate of loss has subsequently slowed (2.2% loss across all altitudes between 2002 and 2014), and much forest remains at higher altitudes: 72% of New Britain remained forested (including secondary forest) in 2014. Despite the ongoing high threat and rich endemic bird fauna, the state of knowledge of the conservation status of birds in New Britain is very poor. We use an unprecedented dataset based on 415 hours of bird surveys conducted in oil palm plantations, as well as primary and secondary forests at all altitudes, to revise the IUCN status of New Britain’s birds. These data indicate that six species of elevated conservation concern are less dependent on old-growth forest than previously assessed. We recommend reduced population size estimates for one species, New Britain Kingfisher Todiramphus albonotatus. We recommend increased population size estimates for seven species: Pied Cuckoo-dove Reinwardtoena browni, Yellowish Imperial Pigeon Ducula subflavescens, Green-fronted Hanging Parrot Loriculus tener, Blue-eyed Cockatoo Cacatua opthalmica, Violaceous Coucal Centropus violaceous, New Britain Boobook Ninox odiosa and New Britain Thrush Zoothera talaseae. Despite our comprehensive surveys, Slaty-backed Goshawk Accipiter luteoschistaceus, New Britain Sparrowhawk Accipiter brachyurus, New Britain Bronzewing Henicophaps foersteri and Golden Masked-owl Tyto aurantia remain very rarely recorded and require further assessment. With ongoing habitat loss, particularly in lowland areas, New Britain’s birds urgently require more attention.

Plant diversity plays the crucial role in maintaining the ecosystem and sustaining the life in the globe. Nepal lying in central Himalaya and at the crossroad of two phytogeographicregionsisbestowed with rich biodiversity. Though the country occupies about 0.1% of global land area but comprises 3.2% of world’s known flora. Biodiversity is eroding because of many factors such as habitat loss, deforestation, infrastructure development, over exploitation for human use, invasion by alien species, global climate change and natural calamities, thus threatening the existence in globe. Nepal has adopted both in-situ and ex-situ conservation practices to conserve the biodiversity and maintain the ecosystem in nature. A network of 20 protected areas is established and national forests under different categories are under protection to conserve the biodiversity in their natural habitats. Scientific forest management was initiated to enhance the forest productivity and conserve biodiversity. Botanical gardens in different localities are established for the conservation of rare, endangered, threatened and endemic plant species. Moreover, Government of Nepal has enlisted some plant species in Government protection list and CITES appendices to prevent them from degradation. Thirty three plant species with medicinal values are prioritized for research and economic development of the nation. Nepal’s approach in conservation of plant diversity is commendable and is at the forefront in in-situ conservation practice. However, a considerable number of plants species that are rare, threatened, endemic are also found outside the protected are as and need to be conserved.

AbstractBats provide important ecosystem services throughout the South Pacific but many species are threatened. The Fiji archipelago has a rich bat fauna yet few arrangements exist to promote the conservation of this group. From July 2008 to March 2011 we visited important sites identified in previous surveys for bats on Vanua Levu, Taveuni, Viti Levu and the Yasawa Islands. We netted and recorded five of Fiji's six bat species (Pteropus tonganus, Pteropus samoensis nawaiensis, Notopteris macdonaldi, Chaerephon bregullae and the Critically Endangered Mirimiri acrodonta). This was only the sixth recorded capture of M. acrodonta. P. tonganus is widespread in Fiji and exploits many different environments. P. samoensis nawaiensis mostly uses forested areas, and large tracts of forest are required for its long-term protection. Cave protection is vital for the two insectivorous species (C. bregullae and Emballonura semicaudata) and N. macdonaldi. In particular, the Nakanacagi maternity site remains globally significant for C. bregullae. E. semicaudata was not caught or detected during our surveys. It appears to be extinct from most large islands in Fiji and has abandoned the only large cave roost (Yaqeta) observed 10 years ago. This species has disappeared from or declined dramatically on Vanuatu, Samoa, Tonga and Fiji. We recommend that the category of E. semicaudata semicaudata on the IUCN Red List be changed to Critically Endangered. Management priorities should focus on community engagement and education, and improved cave and forest management and protection.

Tropical forests constitute the main part of the non-human primate’s habitat but they are more and more fragmented because of anthropic activities. In Ivory Coast, the present forest cover includes only some fragments more or less important. The knowledge of the primate’s diversity and their distribution in these relics of forest constitute some hopeful elements for their conservation. This study has been carried out in two classified forests and a community forest of the Tonkpi area in the West of Ivory Coast. It aims first, to assess the species of primates, then to highlight their spatial distributions and at last, determine their conservation status and the threats there are facing. The methodology used consisted firstly, on interview among hunters and older living around the forests to have an overall view of the monkey species in the area and the forests that housing them. Next, foot surveys have been organized in the identified forests during the interview. At the end of this study, seven species of primates belonging to West African forests have been confirmed in these forest relics base on observation of nests, vocalizations and visual signs. The majority of these species are observed at the periphery of forests mainly in mountain and flooded areas apart from Galagoïdes thomasi which is more abundant even in fallow land. Among those species, one (Piliocolobus badius) is listed Endangered (EN) and Colobus polykomos is considered vulnerable (VU) by IUCN; and five others are least Concern (LC). The sustainable conservation of those primates is threatened by agriculture, traditional and industrial mining, hunting and logging. The existence in those forest relics of primate species with conservation concerned justify their value for the sustainable conservation of those primates and the need to reinforce measure of protection.

Full textAbstract:
SummaryDespite serious and widespread hurricane damage to the natural forests of Jamaica (43% of trees either toppled or with crowns broken in the John Crow Mountains, for instance), the populations of the endemic Ring-tailed Pigeon Columba caribaea, Crested Quail-dove Geotrygon versicolor, Black-billed Parrot Amazona agilis, Yellow-billed Parrot A. collaria, Blue Mountain Vireo Vireo osburni and Jamaican Blackbird Nesopsar nigerrimus appear to have survived Hurricane Gilbert well. However, the expected reduction in food supplies, notably for the frugivores, caused by the severe damage to many trees, coupled with continuing and in some cases increasing human destruction and disturbance of the forests, puts the longer-term survival of these species in some doubt. The establishment of functioning protected areas encompassing the key forest regions for these birds; upgrading and more rigorous enforcement of the legislation governing conservation and management of wildlife and the natural forests; and the control and improvement of agricultural practices around forest areas, would greatly help to ensure the preservation of the forest avifauna and are recommended.

SummaryThree weeks of intensive surveys in Norfolk Island National Park in 2009 failed to find White-chested White-eye Zosterops albogularis and it was calculated that there was a less than 17% probability that a population of 10 birds had been overlooked. The last multi-observer record of this species was in 1978, and it is recommended that the species’ IUCN Red List status of “Critically Endangered” is tagged as “Possibly Extinct”. During these surveys, the population densities of seven bird species were calculated from 352 independent point counts. Causes of imprecision and bias were investigated, suggesting a small underestimation. Other species were recorded too infrequently, or their distributions were too biased, for analysis. The population densities of the extant endemic taxa were relatively high and suggest no current declines, and the population estimates were consistent with previous studies. This study recommends monitoring most species by point counts, or line transects if resources are limited, supplemented with specific monitoring of Tasman (Norfolk Island) Parakeet Cyanoramphus cookii, Pacific Robin Petroica multicolor, Southern Boobook Ninox novaeseelandiae and seabirds. Ongoing monitoring of these birds is needed to help inform management of the National Park and the island in general, given their small population sizes and their likely susceptibility to rat and cat predation, competition from alien species and drought.

ederal policies related to forestry and forest health (specifically, insects and diseases) have the potential to affect management practices, terms of international and interstate trade, and long-term sustainability and conservation. Our objectives were to review existing federal policies, the role of federal agencies in managing forest health, and guidance for future policy efforts. Since the 1940s, various federal policies relevant to forest health have been established, and several US Department of Agriculture (USDA) agencies have been empowered to assist with prevention, quarantine, detection, management, and control of insects and diseases. Overall, our review showed that relatively few national policies directly address forest health as a stand-alone objective, as most of them are embedded within forestry bills. Federal funding for forest health issues and the number of personnel dedicated to such issues have declined dramatically for some agencies. Concomitantly, native species continue to gain pestiferous status while non-native species continue to establish and cause impacts in the US. To enhance our ability and capacity to deal with current and future threats, concerted efforts are needed to advocate for both resources and stand-alone policy tools that take seriously the complexity of emerging sustainability challenges in both private and public forestlands.

SUMMARYInterdisciplinary studies have proved the interconnectedness of history and ecology relevant to forest conservation proposals and management policies. Engaging local views and concerns in the evaluation and monitoring process can lead to more robust knowledge in the pursuit of effective conservation. This study aimed to assess the degree to which land use change trajectories influence the state of tropical dry forest conservation, as evaluated by scientists and local people. Focusing on northern Nicaragua, the research identified three historical trajectories for types and magnitude of forest disturbance. The assessment process included inventorying sites under different trajectories and integrating ecological and social indicators (namely local perceptions of biodiversity value and concern over species threat). The different land use change trajectories had no influence on the present structure of the dry forest, but strongly affected species diversity, composition and their social importance. The study provided evidence of positive species selection by farmers, which suggested a feedback loop between ecological conditions, social value and awareness of conservation.

AbstractA survey of diurnal primate populations was carried out in Odzala National Park, Republic of the Congo, over 3 months in 1994 and 2 months in 1995. The park contains a high diversity and species-specific abundance of primates, and has the highest number of diurnal primates (10 species) in the forest block of Central Africa. Eight species of monkey: greater whitenosed monkey Cercopithecus nictitans, moustached monkey Cercopithecus cephus, crowned guenon Cercopithecus pogonias, De Brazza's monkey Cercopithecus neglectus, talapoin Miopithecus talapoin, white-cheeked mangabey Cercocebus albigena, agile mangabey Cercocebus galeritus and guereza Colobus guereza, as well as gorilla Gorilla g. gorilla and chimpanzee Pan t. troglodytes were sighted in the survey. Monkey species richness was highest in dense inundated forest and thicket, with all eight species occurring in these habitats, whereas only four species were found in terra firma forest (consisting of the park's two main habitats, open-canopy Marantaceae forest and closed-canopy primary forest). Three of the four species (C. nictitans, C. cephus and C. albigena) present in terra firma forest were most abundant in closed-canopy primary forest (1.4,1.0 and 0.6 groups per km, respectively) while the fourth (C. pogonias) was most abundant in open-canopy Marantaceae forest. Gorilla nests were most abundant in open-canopy Marantaceae forest (12.1 nests per km), while chimpanzee nests were mostly found in closed-canopy primary forest and Marantaceae forest (14 and 12 nests per km, respectively). Odzala has the highest recorded densities of western lowland gorilla (mean = 5.4 individuals per sq km) and chimpanzee (mean = 2.2 individuals per sq km) in Central Africa. The high densities of gorillas and chimpanzees may be a result of the high productivity of the forest and low poaching pressure. Conservation measures to ensure the maintenance of conditions in the area, such as educational programmes, are suggested.

SummaryOrnithological surveys were carried out in the remnant forests of the island of Negros, in the central Philippines, over five weeks in the summer of 1991. From this work it is concluded that, without the implementation of immediate conservation measures, the global extinction of four bird species is likely to occur in the near future. These are Negros Fruit-dovePtilinopus arcanus, Negros Bleeding-heartGallicolumba keayi, Writhed-billed HornbillAceros waldeniand White-throated Jungle-flycatcherKhinomyias albi-gularis. Another four species restricted to the lowlands of Negros and the adjacent island of Panay, Visayan Tarictic HornbillPenelopides panini, White-winged Cuckoo-shrikeCora-cina ostenta, Flame-templed BabblerStachyris speciosaand Visayan FlowerpeckerDicaeum (australe) haematostictum, must be considered under extreme threat, and the endemic Negros Striped-babblerStachyris nigrorumis under considerable pressure. A further twelve species listed as globally threatened are also in serious danger of extinction on Negros. This paper details the results of fieldwork and presents our conclusions and suggestions for conservation, which must include the direct preservation of the last fragments of lowland forest on the island.

Full textAbstract:
The littoral forest of the Fort Dauphin region of south-east Madagascar is expected to lose numerous endemic plant and animal species in the near future as a result of deforestation and consequent habitat changes. The disruption of plant-animal interactions is of particular concern. This review describes the conservation status of the littoral forest of Sainte Luce, Fort Dauphin, and examines the role of animal-facilitated seed dispersal in regeneration. The main threats to this habitat are described and possible management implications are discussed in relation to existing initiatives. Protection of the largest remaining forest fragments has been agreed by local communities and a draft plan for forest management is currently under evaluation. Over the next few years plantations will be created to provide local people with wood for fuel and other purposes. An important flying fox Pteropus rufus roost site needs to be included in conservation plans because of its importance for long-distance seed dispersal. Despite the presence of natural barriers, the creation of forest corridors will be crucial for connecting isolated fragments and facilitating genetic exchange between subpopulations. Increased attention needs to be given to the need to promote conservation-related income activities.

The Atlantic Forest is a biodiversity hotspot that includes different types of phytophysiognomies, mainly forests. Hornschuchia, Annonaceae, is one of its endemic genera. Eight Hornschuchia species are found in the tropical moist forest, three of them both occurring in tropical moist forest and tabuleiro forest, a semideciduous seasonal forest, one occurs in the coastal semideciduous seasonal forest and two inhabit the semideciduous seasonal forest and deciduous seasonal forest far from the coast in Bahia. Here we describe the twelfth species of Hornschuchia, which occurs in the Bahian semideciduous seasonal forest, and present a morphological description, illustration, distribution map and assessment of its conservation status.

Full textAbstract:
The sessile oak forests found on the northeast of the Iberian Peninsula are ascribed to the Lathyro-Quercetumpetraeae association and play a key role in understanding the ecology of this habitat, as this region represents its xeric limit. For this reason, we analysed the biodiversity patterns and current conservation status of the sessile oak forests in the region. To do so, we collected Braun-Blanquet inventories of 34 plots randomly distributed throughout the sessile oak forests. The results showed a relationship between the climatic conditions and the biodiversity variables. While the richness of the community increased with decreasing temperatures, the characteristic species found within the community decreased at these same temperatures. This result was due to the presence of most companion species in the cool zones at high elevations.Sessile oaks are found close to other communities, such as silver birches and Scot pine forests.On the other hand, in the warm areas at low elevations, the sessile oak community was more established, with plants typical of this type of forest. These slightly warmer zones with sessile oaks are very important in terms of conservation and more vulnerable to climate change and the thermophilization of the community, as has been studied. As such, protecting and managing these forests is key to conserving this community. Nevertheless, as current protection measures do not safeguard most of these forests, it is essential to define a conservation strategy to preserve them. Using the conservation status, we have established criteria to improve the conservation strategy for sessile oak forest on the NE Iberian Peninsula.

Full textAbstract:
The effects of deforestation patterns, private nature-reserve extents and agricultural fallow periods on forest conservation were simulated for settlement projects in the Brazilian Amazon that produce a fish-bone pattern of occupation and where slash-and-burn agriculture is predominantly used. Data for simulation was obtained from previous work at the Bragantina region, the oldest agricultural frontier in the Brazilian Amazon. Forest conservation was evaluated using the size of remnant forest fragments, the amount of interior habitat, the connectivity among fragments and the extent of fragmentation. Results showed that the best scenario for forest conservation is the maintenance of 80% of the lot as privatereserve using deforestation pattern that allow to group the reserves from different farmers at the end of the lot. When private-reserve coverage is bellow 80% of the landscape, forest conservation status will be influenced by the deforestation pattern. Some patterns (e.g. random location of deforestation plots) will then be particularly deleterious, producing a highly fragmented landscape, while other patterns (e.g., progressive deforestation from one edge) can allow the maintenance of large forest fragments. To get forest conservation in these cases, private-reserve extent and deforestation pattern should be considered together. Considering both forest conservation and agricultural use, progressive patterns of deforestation (or land use) in a lot of 2,000m by 500m, with private nature-reserves covering 50% of the landscape seems to be the best compromise. To guarantee the private forest preservation, these forests should be pre-established when settlements are planned and grouped at the end of the lots.

Full textAbstract:
Sixteen mammal species and 22 bird species whose distributions extended into southwestern Australian forests before European settlement have been listed as threatened at some time in Commonwealth legislation, State legislation, or action plans of Environment Australia or its predecessors. Confident assessment of the causes of conservation status is hampered by poor base-line data, few studies of putative impacts and a preponderance of circumstantial or anecdotal rather than experimental evidence. However, introduced foxes were Implicated In the current conservation status of 62% of the mammal species recognized, while 44% of them were negatively impacted by feral cats, 44% by agricultural clearing and 44% by changed fire regimes. Forestry practices were impllcated in the conservation status of only one mammal species. For the bird species recognized, changed fire regimes had the greatest negative impact (45% affected), agricultural clearing affected 41%, draining of wetlands affected 32% and grazing by livestock affected 22%. Forestry practices were not directly implicated in the conservation status of any bird species. While these results suggest that forestry has had minimal direct impact on the mammals and birds of the forests, the conclusion should be treated cautiously because of the poor data. While awaiting a rigorous evaluation, we argue for a strong precautionary approach to forestry in the region. With proper forest management and sound sylvicultural [sic] treatment there is no reason why there should not be built up on the wreckage of the once splendid forests of Western Australia tended forests which will yield for all time 100 cubic feet of timber per acre per year. Lane-Poole (1920). There are many reasons why Australian environmentalists would like to end logging in native forests. The preservation of wilderness, aesthetics, an almost religious identification with old growth forests and the conservation of forest wildlife figure importantly in environmental efforts to restrict logging. Wilderness and a personal identification with trees and undisturbed forests are fundamentally incompatible with logging. Recher (1996).

Full textAbstract:
Based on field work in 1995 and 1996, we assess the distribution, relative abundance, and habitat preferences of forest plants, lizards, birds, and mammals on 17 islands in the Vava'u Group, Kingdom of Tonga. The islands vary in habitat composition, land area (0.02-96 km2), elevation (20-215 m), and distance (0-10.1 km) from the largest island of 'Uta Vava'u. Two major forest types are recognized - coastal and lowland. They are similar in composition to forest communities described for the southern Tongan island group and for lowland Samoa, but with unique patterns of species dominance. The most mature category of lowland forest persists mainly in areas too steep for cultivation and covers about 10% of the land area. The greatest variation in plant species composition appears to be related to the degree of human disturbance. Among lizards, six species are widespread and at least locally common, whereas three others are localized and typically rare. Among landbirds, 11 species are widespread and at least locally common, one (West Polynesian Ground-Dove Gallicolumba stain) is extremely rare, and three others have been extirpated in the past century. The overall species richness and relative abundance of indigenous plants and vertebrates among islands in Vava'u have been affected more by deforestation and other human activities than by the classic physical variables of island biogeography - area, elevation, or isolation. Small islands (<1 km2) may be very important for conservation purposes, especially given the propensity for secondary succession to indigenous forests following agricultural abandonment.

Non-timber forest products (NTFPs) consist of goods of biological origin other than wood, derived from forests, other wooded land and trees outside forests. The importance of NTFPs for sustaining rural livelihoods, fostering rural poverty alleviation, enhancing biodiversity conservation, and facilitating rural economic growth is well known in Nepal. In spite of these facts, NTFPs have not received the sustained and systematic support. With the gradual rise in population, unsustainable harvesting and depletion of resources, sustainable management of NTFPs has become a challenge. Similarly, the increasing global demand of NTFPs leads to over-exploitation of these resources that further leads to dwindling and adversely affecting the biodiversity. In this context, this paper intends to explore and analyze the conservation status, prospects and challenges for efficient and sustainable management of NTFPs in the context of Nepal.
