Abstract:
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

Abstract:
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.

Abstract:
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.

Abstract:
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.

Abstract:
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.

Abstract:
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.

Abstract:
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.

Abstract:
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.

Abstract:
This thesis reports on the first substantial data collation, analysis and interpretation for a systematic conservation plan for the entire South African forest biome. This was done by addressing the following questions: What is the current state of the forest biome? How well are forests protected? How threatened are they? What are the conservation priorities, and what needs to be done to improve forest conservation? The study is broad and integrative, using information from various published and unpublished sources, as well as expert judgements. The general framework of systematic conservation planning was used along with the software tools typically used for irreplacebility analysis. Rule based modelling, expert judgements and GIS modelling, were used to develop indices of threat, vulnerability, fragmentation, degradation, connectivity and irreplacebility, at the scale of forest patches, forest clusters and forest types. An index of subsistence resource use of forests was modelled using population density, extent of electrification, forest accessibility and the buffering effect of plantations and woodlots. Using these indices, priorities for conservation were identified. Species richness and numbers of red data and endemic species, were also evaluated for each forest type. Forest patches as well as forest clusters were used as planning units, while forest types were used as surrogates to represent forest biodiversity . South African forests have by far the highest number of tree species per unit area of any temperate forest in the world. A high proportion of species occurring in forests are threatened and endemic. At least 56 forest occurring vascular plants and approximately 88 forest occurring faunal species are listed as IUCN red data species. The current forest protected area network of South Africa, does not adequately protect representative samples of forest biodiversity pattern and process. Approximately 25 % of the total forested area occurs within formal statutory protected areas, but most of this is made up of just a few forest types. Of the 21 forest types assessed, six have less than 10% formal protection. Three forest types, Eastern Scarp, Pondoland Scarp and Kwazulu-Natal Dune forests stand out as being highly vulnerable to biodiversity loss, of these; Pondoland Scarp forests have the lowest level of formal protection, and the highest number of endemic species, making this forest type, the highest conservation priority in the country. 10 PhD thesis: Forest conservation planning: Derek Berliner The limitations of the mathematical selection algorithms (C-plan and MARXAN) to incorporate ecological heuristics and context specific information within reserve selection were recognised. In response to this, a rule based modelling approach was used, that enables ecological heuristics to guide the selection of priority forests, This provided pragmatic, but not necessary mathematically optimal solutions to network reserve design. The traditional (largely silvicultural) focus of forest management and reserve planning in South Africa, has tended to view forests as geographically and functionally distinct ecosystems, without adequate consideration of landscape scale processes and requirements for connectivity. For long term conservation of forest biodiversity, planning requires to occur across multiple scales, and with a broader and longer term view than what has been the traditionally focus. Forest conservation needs to involve both on, and off-reserve strategies. This should include: expansion of the formal protected area network (so as to adequately represent all forest types), improvements in management of existing reserves, and regulation of land use change within forested catchments and catchments linked to forests. This should form part of integrated land management strategy that directly involves communities in forest conservation programmes.

Abstract:
Global biodiversity protection requires the development of protected areas that include representative samples of different ecosystems and their associated biodiversity (Dudley 1992, Scott et al. 2001a). I compared long-term decline and protection of forests in three major biomes; boreal, temperate and tropical. I found that forests in the temperate biome are less abundant and less protected than forests in the boreal and tropical biomes. I conducted regional analyses for five continents on the degree of protection of temperate forests across naturally occurring geographic and elevational ranges. My results indicate that protected temperate forests do not represent the full geographic and elevational range of naturally occurring temperate forests. Bias in location, elevation and slope of protected areas are present at both the regional and global scale. Better protection of temperate forests is needed if the diversity and resources associated with these forests types across their geographic range is to be preserved.

Abstract:
The climax vegetation that currently covers the north-western Spain is the deciduous hardwoods forests characterized by different oak species. Galician oaks present a wide-ranging range of ages and qualities, as a result of the different uses and status of conservation. Many of these forests were intensively exploited, and in many cases inappropriate management practices have been applied. However, today these forests comprise a habitat of interest to the European Community and should be conserved, remain basic, in many areas to implement sustainable rural development. Common oak forests (Quercus robur L.) occupy an area of 246,445 ha in Galicia, 18 % of the total forest area. The current location of a lot of oak stands in steep zones indicates that they have remained in such areas from immemorial times because it was not possible the harvesting and these stands are now very important in ecological and landscape terms. The best sites for Quercus robur correspond to zones where the climatic characteristics combine optimally higher minimum temperature, lower thermal amplitude and higher precipitation. Known the present silvicultural status of these forests, alternative methods must be proposed for its management, which will range from a conversion to high forest to recovery of the most deteriorated stands by reforestation.

Abstract:
In Latvia the forest legislation requires that at least five living trees must be retained per hectare after clear-cutting. It is known that retention trees significantly increase the biodiversity in production forest landscape. After clear-cutting retention trees function as habitats for various lichens, mosses, insects, fungi and birds. Over time retention trees are incorporated into the young forests stand and provide presence of old trees, which is necessary for many endangered and rare species. After the death, these trees turn into coarse woody debris which is an essential habitat and feeding source for many taxa. However, the conservation and mortality of the retention trees has not been studied extensively because this approach has been established recently. The aim of this study was to evaluate development of the retention trees in Hylocomiosa type of forests in Southern Latvia. In total 12 young forest stands were surveyed in 2009 and 2015. The total area – 13.7 ha, on average forest stand size varies from 0.5 to 3.0 ha. All the studied sites were harvested in 2002, 2004, 2006 and 2008. All measurements of tree species, height, and diameter and defoliation class assessed and the status of tree (growing tree, coarse woody debris – snags, stems and downed logs) was indicated. Results show that after the studied period of seven years 24 retention trees died. Average level of the tree mortality is 15 %. The mortality level of Scots pine retention trees is 5.8 %, for aspen – 50 % and that for birch – 92.3 %. An average it is 8.5 green retention trees per 1 ha of young stand (22.9 m3 ha-1). On average 2.3 pieces coarse woody debris are per 1 ha of young stand (3.52 m3 ha-1), mostly - aspen wood (2.4 m3 ha-1). Woody debris of the young stands is divided to the first 4 decay levels according to classification (Stokland et al., 2001). 50 % of the listed woody debris is related to the 3rd decay level which means that woody debris is moderately decomposed.

Abstract:
The forest of Chettaba is for ecotourism. Managed by the Forest Conservation of Constantine, this site is formed of several forestry species (hardwood and softwood) spread over an area of 3010 ha. The objective of this study is to estimate the viability of this site through the permanent monitoring of the current state of the forest including biodiversity and pressures. The collection of data related to it had recourse to a forest inventory and an inventory of pressures. The condition was assessed by analyzing these components. The various analyses conducted during this study revealed that the forest is subject to biotic and abiotic pressures and average viability. This is induced by a fairly good stand quality (PHF= 333), medium stability (S= 44.45), low mortality (MR = 4.16%) and good future potential (high regeneration rate (RR =231.25%). Grazing, fire and illegal logging are the most important pressures. Despite these pressures, the forest is classified as a viable ecosystem. However, these potentials are insufficient: it is necessary to reduce the pressures and reforest the degraded plots for better conservation of the ecosystem. To this end, the present study suggests management primarily through silvicultural interventions that promote the regeneration of the various species and to include a permanent ecological monitoring system.

Abstract:
Ecosystem approaches are highly important for pest control in forest reserved areas. Their background is conservation of biodiversity, application of microbial pathogens (bacteria, viruses and fungi) and preparations. Selective and prophylactic natural remedies (attractants, repellents and deterrents) are preferable also. This complex can provide biological security of forest reservations.

Abstract:
In scope of biodiversity and sustainable ecosystem development swamps ecosystem restoration is important, because by eradicating the effect of drainage in swamps, negative impact on adjacent intact or relatively intact raised swamps and hydrological regime of other wetlands is lowered. Tree cutting in degraded swamps forest stands would speed up restoration of ecosystems disturbed hydrological regime. Habitat conservation value in long-term is the same as for habitat 7110* Intact raised swamps, as in case of hydrological regime restoration, within time it will transform into 7110*. Several specially protected plant species can be found only in raised swamps. Tree stand transpiration volume varies depending on air temperature and solar radiation. Since in reality it is impossible to change air temperature or solar radiation in order to increase the groundwater level in a swamp, we can reduce the leaf area index (LAI) which is the most significant value influencing transpiration by cutting down trees. Aim of this paper is to examine how LAI interacts with groundwater level by using system dynamics swamps ecosystem model. Swamps ecosystem model shows correlation between LAI and groundwater level. As a result of this research author observes, that LAI interacts groundwater level and system dynamics modelling could be useful to calculate degraded swamps forest stands thinning intensity through mathematical relationships.

Abstract:
Ensuring pipeline stability is a fundamental aspect of subsea pipeline design and can contribute a significant proportion of project costs in regions with large diameter trunklines, shallow water and severe geotechnical and metocean conditions [1]. Reducing the conservatism and simplifications of existing pipeline stabilisation design methods therefore offers economic benefits to hydrocarbon producers necessary to ensure the ongoing viability of projects in these regions. To realise this potential and reduce the conservatism of the existing design methods, a more accurate understanding of the hydrodynamic loads exerted by waves and currents is required. This paper investigates one of the inherent assumptions incorporated into the existing design methods through the arrangement of previous experimental investigations to determine whether rectilinear motion provides a reasonable approximation to simulate the near seabed orbital particle paths in wind-generated waves. This assumption is based on the flattening of particle paths to ellipsoids with depth and ignores the small vertical velocity components near the seabed. Based on the hydrodynamic forces calculated numerically using a validated Computational Fluid Dynamics (CFD) model for rectilinear and orbital wave modelling it is concluded that pipeline stabilisation requirements calculated in accordance with the DNV-RP-F109 absolute lateral static stability design method and rectilinear wave motion assumption are conservative. It is also concluded that the hydrodynamic force asymmetry in favour of the reverse half wave cycle caused by the vertical velocity components in orbital wave conditions requires further consideration to determine the implication for dynamic lateral stability design methods.

Full text
Abstract:
The conditions under which rothalpy is conserved are investigated by means of the energy and moment-of-momentum equations for unsteady flow of a viscous, compressible fluid. Differential and integral equations are given for the total enthalpy and rothalpy in both stationary and rotating coordinates. From the equations in rotating coordinates it is shown that rothalpy may change due to: (1) pressure fluctuations caused by flow unsteadiness in the rotating frame; (2) angular acceleration of the rotor; (3) work done by viscous stresses on the relative flow in the rotating frame; (4) work done by body forces on the relative flow; (5) changes in entropy due to viscous dissipation and heat transfer. Conclusions of this investigation are compared with those of previous authors, some of whom have stated that rothalpy is conserved even in viscous flows. A modified Euler’s turbomachine equation which includes viscous effects is derived and errors in previous derivations noted.

Full text
Abstract:
The aim of the study is to evaluate carbon stock in litter and organic forest soils in Latvia as well as to characterize accumulation of carbon in litter in afforested lands. The study is providing empirically valid information about soil and litter carbon changes for the National greenhouse gas (GHG) inventory by using data from National forest inventory (NFI), forest soil monitoring demonstration project BioSoil and other studies. The study proves significance of organic forest soil carbon pool in Latvia and demonstrates necessity to extend NFI incorporated forest soil monitoring program to improve data on soil density in wet organic soils, as well as to integrate data characterizing water regime in forests. The acquired data also proves that the conservative approach of calculation of carbon stock changes in litter in afforested lands applied in the Latvia’s National GHG inventory avoids overestimation of CO2 removals. The data on litter carbon stock collected in this study is sufficient to estimate total carbon stock for stands dominated by most common tree species and long term impact of changes of species composition. Measurements of organic soil and litter thickness should be continued by NFI and integrated with more detailed soil monitoring to increase accuracy of carbon stock estimates and gather data necessary for verification of modelling data, particularly in afforested lands and due to change of dominant species.

Abstract:
City as a man creation is always experiencing transformation from time to time. The city center area, originating from a residence area has turned into a commercial area for trading. This transformation is recognized by the physical building change. This paper will describe building transformation in the Pasar Baru area, which is a conservation area in the city center of Bandung city, Indonesia. Colonialism left dualism of the land status in this area, formal and informal. Formal land is located on the road side shaped as row shop houses whilst the informal land lies behind the shop houses in form of urban kampong. The improvement of business and trading, demands a larger working area so space expansion is needed. The difference of land status and location makes it possible for shop house owners to expand their lot toward the kampong behind. Nowadays old shop houses as conservation buildings are hard to recognize because they have been transformed into new shop house forms. By observing the shape it’s expected that the lot expansion was the motivating factor. How did the transformation occur? Can transformation on one land lot give contribution to transformation on the city? It’s expected that the occurring transformation should not eliminate the conservation, building and area in the city center and the residential function could still be maintained.

Abstract:
Tree species are characterized by their perennial growth habit, woody morphology, long juvenile period phase, mostly outcrossing behaviour, highly heterozygosity genetic makeup, and relatively high genetic diversity. The economically important trees have been an integral part of the human life system due to their provision of timber, fruit, fodder, and medicinal and/or health benefits. Despite its widespread application in agriculture, industrial and medicinal values, the molecular aspects of key economic traits of many tree species remain largely unexplored. Over the past two decades, research on forest tree genomics has generally lagged behind that of other agronomic crops. Genomic research on trees is motivated by the need to support genetic improvement programmes mostly for food trees and timber, and develop diagnostic tools to assist in recommendation for optimum conservation, restoration and management of natural populations. Research on long-lived woody perennials is extending our molecular knowledge and understanding of complex life histories and adaptations to the environment, enriching a field that has traditionally drawn its biological inference from a few short-lived herbaceous species. These concerns have fostered research aimed at deciphering the genomic basis of complex traits that are related to the adaptive value of trees. This review summarizes the highlights of tree genomics and offers some priorities for accelerating progress in the next decade.
