Volant and non-volant small mammals from three forest reserves, located inside and outside Selangor State Park, Malaysia, were trapped and documented. A total of five-line transects, each 200 m long and a total of 100 collapsible cage traps, three harp traps and ten mist nets were deployed at each study site to capture rodents and bats species. The presence of 47 species of volant and non-volant mammals was documented with the highest abundant species being <i>Leopoldamys sabanus</i> (n = 61). The Family Vespertilionidae was the most diverse, while Muridae was the most abundant species. Diversity indices have shown forest reserves - Gading Forest Reserve (FR) and Bukit Kutu FR – located in the State Park, have a higher species composition than the impaired adjacent forest reserve, Bukit Tarek FR extension. The taxonomic diversity and taxonomic distinctness of the three forest reserves ranged between 2.433 and 2.610, while the taxonomic distinctness values ranged between 2.638 and 2.748. Even though Gading FR recorded the highest number of species diversity, the Chao 1 diversity estimator and the rarefaction accumulation curve indicated that Bukit Kutu comprised more species. Comparisons between other state parks and national parks in Peninsular Malaysia indicated that Selangor State Park indeed harbours relatively more species of small mammals. Northern Selangor State Park and adjacent forest should be recognised as a conservation priority area, although there are comparatively more species harboured in other regions of the State Park. With the current information on fauna diversity, proper management should be formulated to preserve the existing ecosystems in order to ensure the continuity of fauna diversity in Malaysia.

Abstract Unabated land use changes in developing countries have imperilled the urban ecosystem resilience. An urban protected area is one of the critical systems to absorb disturbance regimes in the metropolitan area, but it is increasingly pressured by urbanization. Therefore, assessing their land use and landscape pattern changes are pivotal to identify the conservation capacity. We developed land use maps for Klang Gate, Bukit Kutu, and Sungai Dusun wildlife reserves to assess their spatial and temporal land use changes between 1988 and 2012. The degree of fragmentation, the intensity of human impact and structural connectedness for these wildlife reserves were also quantified. The findings revealed that Klang Gate which located adjacent to the highly urbanizing area experienced a very significant loss of forest while built-up area and commercial agriculture gradually encroached into the reserve. It also has a higher degree of fragmentation and human impact than the other two reserves. Human impact inside of Klang Gate was concomitant to the outside. However, Bukit Kutu almost undisturbed and Sungai Dusun was slightly intruded by commercial agriculture. The results help different stakeholders, such as managing authorities and policy planners to strategize new land use planning that utilize limited land-based resources for future economic and social development. As the findings showed that urban protected areas alone are not sufficient in maintaining the urban ecosystem; therefore new conservation planning that integrates other urban green spaces at their surrounding is critical to ameliorating the conservation on a long-term basis.

Based on Article 50 of Law Number 41 of 1999 concerning Forestry, it is regulated that everyone is prohibited from encroaching on forest areas and cutting down trees in forest areas. The enactment of Law Number 18 of 2013 concerning Prevention and Eradication of Forest Destruction has further strengthened the legal basis for forest protection in Indonesia. Based on Article 12 of Law Number 18 of 2013 concerning Prevention and Eradication of Forest Destruction, it is regulated that everyone is prohibited from cutting trees in forest areas. However, in 2017, the Riau Regional Police succeeded in uncovering a case of illegal logging that occurred inside the Giam Siak Kecil-Bukit Batu Biosphere Reserve in Siak Regency. The method used in this research is sociological law research. The application of sanctions against perpetrators of forest destruction of the Giam Biosphere in Siak Regency based on Law Number 41 of 1999 concerning Forestry and Law Number 18 of 2013 concerning Prevention and Eradication of Forest Destruction has not been optimal. The community cannot be blamed for forest encroachment and tree cutting inside the Giam Siak Kecil-Bukit Batu Biosphere Reserve in Siak Regency because the Giam Siak Kecil-Bukit Batu Biosphere Reserve before it became a state-protected biosphere reserve was where the community lived. The Giam Siak Kecil-Bukit Batu Biosphere Reserve in Siak Regency has been inhabited and managed by the community for generations to meet the needs of daily life. There are two efforts made to prevent the destruction of the Giam Siak Kecil-Bukit Batu Biosphere Reserve forest, namely preventive efforts and repressive efforts. In addition, the concept of implementing administrative sanctions as primum remedium and the principle of strict liability offered in Law Number 32 of 2009 concerning Environmental Protection and Management is part of sustainable development efforts.

Full textAbstract:
The 71 hectares mainly of rain-forest on Bukit Timah Hill have been isolated for more than 130 years. During most of this period, the forest has received some form of protection: initially for climatic reasons, then as a forest reserve, and finally as a Nature reserve. It has also suffered a great deal of disturbance from illegal logging, firewood collection, hunting, wartime shelling, and recreational activity. Despite this, the Reserve still supports an immensely rich flora and fauna, although many bird and mammal species have been lost.The example of Bukit Timah suggests that, contrary to most predictions, small rain-forest reserves can play a significant role in biological conservation, as well as satisfying educational and recreational needs.

Full textAbstract:
One of the problems faced in the management of conservation areas, including wildlife reserves, is the community activities in and around the area to meet their daily needs. They in general have traditionally carried on their traditional lives and most of them live at a very subsistence economic level. Therefore the success of the management of conservation areas including wildlife reserves is very dependent on the attitudes and support of the community both at the local and national level. Bukit Rimbang Bukit Baling Wildlife Reserve has been determined by the Government of the Republic of Indonesia through the Decree of the Minister of Forestry number SK.3977/Menhut-VII/KUH/2014 on May 23, 2014 with an area of 141,226.25 hectares (BBKSDA Riau, 2015). Tanjung Belit Village, Kampar Kiri Hulu Subdistrict, Kampar Regency is one of the villages bordering the Bukit Rimbang Hill Baling High School which has high public concern for the preservation of the forest, rivers and the surrounding environment. The people of Tanjung Belit Village have traditionally used natural resources in and around the Bukit Rimbang Bukit Baling Wildlife Reserve area to fulfill their daily needs by farming / gardening and collecting forest products and other river products. However, the availability of these forest and river resources, if taken continuously, will certainly decrease both in quality and quantity. While the necessities of life always increase along with the increasing population and the progress of the times. Therefore efforts should be made to the community and natural resources, so that the availability of natural resources and the necessities of life can be improved. This study aims to analyze the socio-economic conditions of the people of Tanjung Belit Village, identify the potential of Bukit Rimbang Bukit Baling Wildlife Reserve, formulate the Tanjung Belit Village community empowerment strategy around the Bukit Rimbang Bukit Baling Wildlife Reserve, Kampar Regency, Riau Province. The research approach used in this study is a quantitative approach to the survey method.he results showed the socio-economic conditions of the people of Tanjung Belit Village were still classified as poor and less skilled. However, local wisdom and a strong will to try to be a social capital in community empowerment. The potential of Bukit Rimbang Hill Bukit Baling has quite high potential from flora, fauna and nature tourism, but for the development of agricultural business is still limited due to the status of the wildlife reserve. The results of the study can be formulated a strategy of community empowerment in the village of Tanjung Belit around Bukit Rimbang Bukit Baling Wildlife Reserve; (a) optimize land use in agricultural business development; (b) encourage training activities to improve human resources in the context of community empowerment; (c) active community involvement in the management of the Bukit Rimbang Bukit Baling Wildlife Reserve area; (d) increasing cooperation support between the government and stakeholders in developing infrastructure supporting natural tourism around the Bukit Rimbang Bukit Baling Wildlife Reserve.

One of the causes of forest destruction by humans is their lack of understanding of the economic value of forest ecosystem services. One of the forest ecosystem services is water management services. In order to encourage people to protect forests, they need to be given knowledge about the economic value of forest water that is used daily. The Bukit Bungkuk Nature Reserve is a conservation area in Riau Province. From this area flow three tributaries to the Merangin Village area. This study aims to calculate the economic value of the hydrological function of the Bukit Bungkuk CA area as a provider of household water for the Merangin Village community. The research was conducted by measuring river water discharge and using a questionnaire to calculate household water use. Based on the results of the study, it is known that the amount of water used is 125.0015 m3/day. The price of PDAM Tirta Kampar water is Rp. 4.500/m3, the economic value of water from Bukit Bungkuk Nature Reserve in Merangin Village is Rp. 562,506.72/day or Rp. 205,314,953/year. While the total economic value of water is Rp. 536,371,015,5 /day or Rp. 195,775,420,657/year.

Full textAbstract:
Bukit Nanas Forest Reserve, the oldest forest reserve in Malaysia established in 1900, lies in the center of Kuala Lumpur, the capital city. Over time it has been reduced from 17.5 ha to 9.37 ha but still retains important biodiversity. Its lowland equatorial rain forest has never been logged and tall emergent species to 35 m tall and 124 cm diameter persist. Since 1900, 499 plant species (2 lycophytes, 25 ferns, 39 monocots and 433 dicots) have been recorded. This year-long survey refound 425 species, including the rare <i>Tarenna rudis</i> (Rubiaceae), a local endemic found only in Selangor state. The multi-layered structure of lowland dipterocarp forest (16 Diperocarpaceae species were recorded) is intact. However, with diminishing size, the edge effect is more pronounced with secondary forest species, from trees to herbs, becoming established. In 2009, declared as the KL Forest Eco Park, it is important for its biodiversity, history, accessibility to the public for recreation (forest walks), scientific study, education (natural history, bird-watching, etc), as well as serving as a green lung in the bustling city. Baseline data, such as this survey, enables scientific management that will maintain the forest structure and biodiversity.

This paper discusses the preliminary results of the first comprehensive survey of the spiders of the Bukit Timah Nature Reserve (BTNR) in Singapore. Two plots were established in each of the three zones of vegetation, viz., primary forest, old secondary forest, and maturing secondary forest. They were repeatedly sampled over an 18-month period. Sorting of the collection so far suggests that the three vegetation zones harbour rather different spider assemblages. Only ~9% of the total spider fauna recovered was shared by all three zones. The results have also yielded a preliminary picture of dominance, abundance and rarity. Although first intended to obtain a baseline for future quantitative analyses, the survey became a testing ground to modify and refine methodology so as to conduct future quantitative surveys with greater scientific rigour. Taxonomic work on the samples so far shows that the spiders in the BTNR span over 43 families, of which six families are listed for the first time in Singapore. The tally is summarised in an interim checklist of BTNR spiders. The checklist, with a total of 317 entries, shows that there are 158 described species of spiders in BTNR, of which 25 species are new records for Singapore. Another 159 morphospecies are provisionally recognised as distinct species, some of which may be new to science. Our observations during the survey have allowed us to provide a narrative of BTNR spider diversity against a backdrop of their microhabitat specialisation.

Understanding how abiotic factors influence Bornean tropical tree communities and diversity is a key aspect in elucidating the mechanisms of species co-existence and habitat preferences in these biodiverse forests. We focused on investigating forest structure, tree diversity and community composition of lowland Bornean heath forests in Brunei Darussalam, within two 0.96 ha permanent forest plots at Bukit Sawat Forest Reserve and Badas Forest Reserve. All trees with stem diameter ≥ 5 cm were tagged, identified and measured for their stem diameter and basal area. Soil physiochemical properties (pH, gravimetric water content and concentrations of total carbon, nitrogen, phosphorus, potassium, calcium and magnesium in topsoil) and environmental factors (relative humidity, canopy openness, litter depth and topographic variables of elevation, slope and aspect) were quantified as potential drivers of tree community differences. A total of 2,368 trees were recorded, representing 229 tree species in 211 genera and 58 families. Significant between-site differences in forest structure and tree community compositions were detected, despite limited differences in environmental and soil properties. Tree community composition at Bukit Sawat appeared to be influenced by topographic variables, while those at Badas were influenced by canopy openness. Our results showed that small-scale soil and environmental variation appeared to shape the local tree communities at Bukit Sawat and Badas. We recorded numerous Bornean endemic and tree species of high conservation values. We thus highlight the necessity of conducting long-term research on the forest dynamics of Bornean heath forests to effectively manage these high conservation value habitats which are currently experiencing changes driven by disturbances.

Full textAbstract:
Lowland tropical rainforests provide an abundance of biodiversity as well as dynamic and stable ecosystems. These forests include tropical peat forests in various locations and forest types that have vegetation structure and composition characteristics, and carbon stocks that still need to be explored more deeply. Research on the structure and the composition of the vegetation and carbon stock in the old secondary peat forest was carried out in the protected areas of Bukit Batu, Riau Province, and Muara Merang, South Sumatra Province. Based on a 1-hectare permanent plot established in Bukit Batu and Muara Merang, 25 subplots of 20 m by 20 m were established in each location for measurement purposes. The results showed that Bukit Batu and Muara Merang had 42 and 36 species belonging to 26 and 20 families, respectively. Bukit Batu had a species diversity index (H’) of 2.93, and the dominant tree species were Palaquium xanthochymum with an importance value index (IVI) = 66.27%, Eugenia sp. (IVI = 32.76%), and Litsea sp. (IVI = 18.39%). The Muara Merang location had a species diversity index (H’) of 2.82, and the dominant tree species were Eugenia sp. (IVI = 60.88%), Alseodaphne insignis (IVI = 26.34%), and Adenanthera pavonina (IVI = 22.11%). In Bukit Batu, forest stands with a diameter of ≥10 cm contained a biomass of 178.10 tonnes/ha and carbon stock of 83.70 tonnes C/ha, which is equal to 307.20 tonnes CO2/ha. Meanwhile, in Muara Merang, it was 190.41 tonnes/ha and 89.49 tonnes C/ha, which is equal to 328.44 tonnes CO2/ha. This research, especially that in Bukit Batu, Riau Province, enriches the data and information available to date and is very useful in supporting restoration practices in Riau Province’s Giam Siak Kecil Biosphere Reserve, which was designated by UNESCO as part of the Man and Biosphere Program.

Full textAbstract:
The phenological events of rattan were seldomly studied due to its nature of survival by climbing on other trees (i.e., liana). However, some rattans are non-climbing and found to produce fruits throughout the year. Therefore, it aimed to record Calamus castaneus duration of flowering and fruiting over a year and identify which environmental variables affect the duration. This study was conducted for 12 months in three forest reserves, namely Bukit Mertajam Forest Eco-Park (BMFEP), Teluk Bahang Forest Reserve (TBFR), and Segari Melintang Forest Reserve (SMFR). Five study plots (10 m × 10 m each) were established, and overall, 53 C. castaneus individual palm in the plots were monitored. Findings have revealed that female inflorescences bloomed shorter than males. Also, C. castaneus fruits take about three to four months to get matured. The canonical correspondence analysis (CCA) highly regulated the event by microclimate and locality. Thus, the flowering and fruiting duration may not directly be affected by a very specific environmental factor.

Fungi is primary microorganism which produced cellulase enzyme. Cellulase was catalyzed cellulose from plants or organic waste in enzymatic reaction to be glucose, cellobiose and short polysaccharide. Cellulolytic fungi were isolated from Giam Siak Kecil-Bukit Batu (GSKBB) biosphere reserve. GSKBB is a natural peat swamp forest, with a peat bed reaching up to 9.2 m. Peat swamp forest is a potential source for new species of fungi which produced cellulase in low pH and very good activity because peat swamp forest had been many cellulose and acid pH. Fungi strain was assigned as RH01 at Aspergillus for genus based on microscopy analysis. Index cellulolytic of RH01 was 2.31 and cellulase activity had values of 0.0125 U/mL.

AbstractThe Singapore freshwater crab Johora singaporensis is known only from three streams in Singapore and is among the top 100 most threatened species in the world. It is the only member of the genus Johora, endemic to the Malay Peninsula, to be categorized as Critically Endangered on the IUCN Red List. Extensive surveys conducted over 1 year to determine the extent of the species’ distribution revealed that the population has declined significantly at its type locality in Bukit Timah Nature Reserve, Singapore Island's oldest protected forest area. The species remains extant in two unprotected streams in Bukit Batok and Bukit Gombak, which are located outside the nature reserve. Acidification of streams as a result of acid precipitation may be a factor in the decline of the species. If so, this will be the first documented instance of a species being affected negatively by anthropogenic acidification of a tropical freshwater system. The occurrence of this threatened species in a protected area has not, therefore, guaranteed its survival. There is a need for long-term and continuous monitoring of species of high conservation value, together with other measures that focus on habitat protection. Conservation efforts by the National Parks Board of Singapore in collaboration with other government agencies are ongoing in an effort to ensure the survival of this important species.

Full textAbstract:
ABSTRACTThe 71 ha Bukit Timah Nature Reserve contains the largest surviving area of primary rain forest in Singapore. The recorded vascular plant flora of the forest consists of at least 854 species: 787 angiosperms in 109 families, 65 pteridophytes and three gymnosperms. 58.6% of the species are trees or shrubs, 18.7% climbers, 12.3% terrestrial herbs, 8.8% epiphytes and hemi-epiphytes, 1.0% saprophytes and 0.6% parasites. The four families with most species -Rubiaceae, Euphorbiaceae, Orchidaceae and Moraceae - account for a quarter of the angio-sperm flora but contribute few large trees. Community reproductive phenology is charac-terized by supra-annual bursts of general flowering and fruiting, contrasting with a low back-ground level. After an exceptionally dry and sunny February, 1987, more than 150 species in 42 families flowered between late March and late May, followed by an equally well-defined fruiting peak 13 weeks later, between late June and late August.

(Uploaded by Plazi for the Bat Literature Project) Surveys on Roundleaf bats (Hipposideridae) were conducted at 18 forest reserves in nine CFS ecological corridor networks namely Pedu, Bukit Saiong, Kenderong, Bintang Hijau, Sungai Betis, Sungai Brok, Tembat, Tanum, Sungai Yu, Ulu Jelai, Bukit Bujang, Angsi, Berembun, Labis Timur, Mersing, Lenggor Tengah, Panti and Ulu Sedili FRs. This study mainly aims to record the presence of Hipposideridae at the selected forest reserves. The surveys started from February 2018 until August 2020. A total of three harp traps were set up in each forest reserve, except for Ulu Jelai, Tembat and Berembun FRs with six harp traps. Overall, 67 individuals comprising seven species from genus Hipposideros were recorded in this study. Hipposideros bicolor was the most widely distributed species recorded in nine forest reserves whereas, Hipposideros larvatus is the most abundance species recorded in this study with 25 individuals. Kenderong and Bintang Hijau FRs recorded the highest number of Hipposideridae species in this study, both with four species. The presence of Hipposiderids in this study might be associated with their suitable roosting and foraging areas as well as availability of food sources. Therefore, this information gives an early insight on Hipposideridae distribution and habitat requirement at the forest reserves in CFS ecological corridor landscapes that stakeholders need to consider in establishing the corridors. More sampling efforts need to put in this study, covering more areas in the forest reserves with longer sampling periods and more number of traps used in order to really identify critical corridors for bat conservations.

Abstract Peatland fires affect the diversity of bacteria, particularly key species bacteria (BKS). BKS has an important role in the structure of ecological community as key taxa to forming the composition and function. This study determined unique BKS candidates of the secondary forest which may not be found in burned areas. These candidates were detected in silico from the 16S rRNA gene sequence. The 16S rRNA gene sequence was determined by next-generation sequencing (NGS) method from peat soil DNA sampled from secondary forest and burned areas in the Giam Siak Kecil Biosphere Reserve, Bukit Batu (GSK-BB). BKS candidates were selected from a phylogenetic tree constructed by using MEGA version 6.06. Selected BKS was in the same cluster as secondary forest and were re-selected using BLASTn: AlignTwo or More Sequence analysis to ensure the uniqueness of the sequences. Based on the selected candidates, specific primers were designed to amplify the 16S rRNA BKS gene. Sensitivity was tested in silico using FastPCR application to ensure that candidates were only in secondary forest. There were 19 BKS candidates found in the secondary forest and not in burnt land (BKS_SFB) that were classified into three groups. Based on the in silico PCR amplification of the 16S rRNA gene using the designed primer, we obtained two high specificity BKS candidates, i.e. BKS SFB2 (455 bp) and BKS SFB3 (473 bp). The two candidates are potential as DNA barcodes for peatland quality monitoring after burning.

Full textAbstract:
An avifaunal survey was carried out at Bukit Balingkadus Forest Reserve in Ranau, Sabah, Malaysia. The MacKinnon List method was used to assess species diversity. The four-day survey recorded a total of 16 MacKinnon lists with 388 individuals detected. A total of 86 species from 37 families were recorded, with H=3.89 and EH=0.65. True species richness was estimated (using SuperDuplicates® online calculator) to be approximately 114 species, with approximately 28 species not detected. There were 13 species of Bornean endemics, two of which were listed as Vulnerable in the IUCN Red List of Threatened Species. Pycnonotidae was the most speciose family with 10 species. Cuculidae and Megalaimidae were ranked second with 6 species each. Zosteropidae had the highest number of individuals at 47. The top ten most detected species made up 49.5 % of all species detected. The most detected species was the Chestnut-crested Yuhina (Zosteropidae). The majority of the species detected (81) were forest-dependent, of which 60 were strictly forest birds. Insectivores made up the most dominant dietary guild, i.e., a total of 41 species (from 22 families). Frugivores ranked second with 29 species from 10 families.

Full textAbstract:
Bukit Rimbang Bukit Baling landscape in Riau is not only a habitat for the Sumatran tigers but also for indigenous people who have resided the area for centuries. These communities highly depend on the landscape for livelihood, with 94.1% engaged in rubber farming and non - timber forest product (NTFP) harvesting. Landscape designation as a Wildlife Reserve has been limiting the communities' activities. The remote condition, coupled with the decline in global rubber prices, has further increased the vulnerability of these communities to poverty. This study aims to provide an in-depth analysis of the welfare of the six villages adjacent and within the reserve by estimating the ability to meet the 2100-calorie intake threshold as one of indicators in calculating the poverty line, compared to the communities’ monthly income. Field observation and secondary data involving 604 community members were analyzed using descriptive methods. The study found that income from rubber alone covers only 20.27% (425.67 kcal) of the daily calorie requirement, possibly increasing to 28.51% (598.71 kcal) for those who received government subsidies. This condition led communities to engage in activities to meet calorie needs and supplement income, such as NTFP harvesting, fishing, gardening, and potentially, unlawful activities like subsistence logging and wildlife hunting.

Full textAbstract:
A study of butterfly species diversity was conducted in Chemerong Amenity Forest, Terengganu, Malaysia. A total of 939 individuals from 198 butterfly species were obtained using fruit-baited sweep nets and modified VanSomeren-Rydon cylinder traps. The biodiversity of butterflies in the study area was considered high, with a Shannon index (H’) of 4.1, Simpson’s index (DSimpson) of 0.042, and Margalef index (IMargalef) of 28.78. Individuals within the community were not evenly distributed among the species (EShannon= 0776). Nymphalidae was found to be the most dominant family (48.5%), and Lexias dirtea merguia was the most abundant species recorded with 114 individuals (12%). From the total of eight species protected under Malaysia legislation, one species Trogonoptera brookiana was also listed under CITES Appendix II, while only one protected species Agatasa calydonia calydonia of the family Nymphalidae (the brush-footed or four-footed) was considered rare. Other rare species found in this study included Arhopala lucida, Curetis saronis sumatrana, Miletus nymphis fictus of the family Lycaenidae (the blues, coppers, & hairstreaks), Amathusia perakana perakana, Bassarona teuta goodrichi, Elymnias saueri saueri, Elymnias nesaea, Mycalesis horsfieldi hermana, Mycalesis distanti, Ypthima pandocus tahanensis of the family Nymphalidae (the brush-footed or four-footed), Celaenorrhinus ladana, Erionota sybirita, Matapa aria, Matapa cresta, Matapa druna, Pseudokerana fulger, Taractrocera ardonia, Taractrocera luzonensis, Telicota linna, and Unkana mytheca mytheca of the family Hesperiidae (the skippers). The dominance of family Nymphalidae may be due to several factors, including high species diversity, widespread distribution and occurrence, as well as the type of bait used in this study. Besides the Genting Highlands and Taman Negara Johor Endau Rompin, butterfly species at Chemerong Amenity Forest are more diverse than other study sites in Malaysia such as Gunung Serambu, Ulu Gombak Forest Reserve, Setiu Wetlands, Kuala Lompat, Bukit Hampuan Forest Reserve, Sungai Imbak Forest Reserve, Tabin Wildlife Reserve, and Ulu Senagang Substation. Further investigation of aspects such as stratification distribution patterns, host plants and forest dwelling species are recommended for better understanding of butterfly communities in the Chemerong Amenity Forest.

(Uploaded by Plazi for the Bat Literature Project) Bat species commonly comprise at least 50% of tropical mammalian assemblages, but Afrotropical bat faunas have been little studied leading to perceptions that they are depauperate. Here, we compare alpha taxonomic, functional, and phylogenetic diversity of insectivorous bats belonging to the narrow-space foraging ensemble from a bat diversity hotspot in Nigeria to species-rich sites in Indonesia and Malaysia, using previously published data. The Nigerian site is protected unlogged forests at Afi Mountain Wildlife Sanctuary and Cross River National Park. For comparison, we targeted similar unlogged forest sites in Southeast Asia: Indonesia—Bukit Barisan Selatan National Park Forest in Sumatra; and Kakenauwe Forest Reserve on Buton Island, Sulawesi; and another in Malaysia—Krau Wildlife Reserve. All sites were sampled using comparable methods, with an emphasis on harp traps that effectively capture the forest-interior ensembles. We also compare regional beta diversity of bat assemblages in ecoregions using occurrence data (literature, unpublished records, and online natural history collections) from the Lower Guinean Forest and the Malay Peninsula. We demonstrate comparable alpha taxonomic, functional, and phylogenetic diversity of narrow-space bats among sites in Nigeria and Indonesia, but greater diversity in Malaysia. Turnover and overall beta diversity of bats among ecoregions was comparable between the Lower Guinean Forest and the Malay Peninsula, but nestedness was higher in the latter. Our results reiterate the value of harp traps in generating bat survey data that allows equatable comparisons of "mist net avoiders" in the Paleotropical forest understory. Our findings have implications for regional and local bat conservation.

Abstract Shorea platyclados, known to the public as Meranti Bukit, is one of the species whose existence S. platyclados Slooten ex Foxw. or what is known by the local name Meranti Bukit is a type of meranti tree that has fast growth and is recommended as a plant for forest and land rehabilitation activities. S. platyclados is threatened in nature and is included in the Near Threatened (NT) its category based on the IUCN Redlist. Conservation efforts are needed to better understand natural habitat conditions and increase the population of S. platyclados in nature with an ecological approach. An association is a common kind of community that is present in many places and occurs under similar circumstances.. Associations are characterized by having a similar floristic composition, having a uniform physiognomy, and their distribution having a unique habitat. Studies on plant associations around S. platyclados have yet to be revealed so a more in-depth ecological analysis is needed to determine the relationship between S. platyclados and other plants around it. The purpose of this study was to analyze the association between S. platyclados and the dominant trees in the Martelu Purba Nature Reserve area. Using the 2x2 Contingency Table, association analysis was performed on the primary constituent species with an IVI of ≥10%.. The results of the analysis of the type of association between S.platyclados and the dominant tree showed positive for Charcoal and Akhirsap species, while for Modang, Beringin, and Kemenyan species negative association.

Among the potential natural resources of Bukit Rimbang Wildlife Reserve, Baling Hill is Batu Dinding Waterfall and the Subayang river flow which has now become one of the potential tourist objects and has been designated as an ecotourism area. In recent years, ecotourism has been quite visited by surrounding communities and including the City community. Support from various parties is needed to build a sustainable ecotourism including institutional development and infrastructure. Community service activities will be carried out in Tanjung Belit Village, Kampar Kiri Hulu District, Kampar District. The target of the activity is the Village Apparatus, Community Leaders and members of the Sadar Wisata group. The purpose of service activities: 1). Identify and formulate village potential so that the community is able to become a part of developing ecotourism in Tanjung Belit Village. 2). Find a model of community empowerment in developing Tanjung Belit ecotourism that is based on culture and local wisdom. From the results of the service it was obtained that this activity went well. Enthusiastic participants were high, especially from members of the tourism conscious group Tanjung Belit Village, then ninik mamak, village officials and the community. The outreach material delivered provides enormous benefits and the discussion is very interesting, namely increasing the ability of the community to see and develop village potential, especially in the field of tourism. With the increase in public awareness, it is expected that participation from various parties, both local and private governments, will also help in providing various tourism support facilities and infrastructure so that the potential for tourism visits is higher. Thus it is also expected that in the future the economy of the community can improve through the tourism sector.

ARTICLE HIGLIGHTS- The survey method was successful in identifying the species Marchantia and mapping their distribution in North Sumatra- Eight taxa of Marchantia confirmed in North Sumatra, M. emarginata subsp. cuneiloba has the most widely distributed species. - Species distribution linked to environmental factors like elevation, humidity, rainfall, soil types, slope, solar intensity, and types of land coverABSTRACTMarchantia is one of the large genus complex thalloid liverworts (Marchantiophyta). The species of Marchantia has a wide distribution throughout the world, and occupies a variety of substrates. Studies on the presence and distribution of Marchantia species are still limited in North Sumatra. Therefore, the research was carried out to inventory the species of Marchantia and map their distribution in North Sumatra. Survey method was used to inventory the species of Marchantia, covering 9 locations, namely: Aek Nauli Forest, Bukit Barisan National Forest Park, Bukit Lawang, Resort Cinta Raja, Dolok Tinggi Raja Nature Reserve, Sibayak Mountain, Sicike-cike Natural Park, Silima-lima waterfall, and Taman Eden 100 Natural Park. Geographic Information System (GIS) was used to map the distribution of the species. The results showed that there were eight taxa of Marchantia confirmed in North Sumatra, namely, M. acaulis, M. emarginata subsp. emarginata, M. emarginata subsp. cuneiloba, M. geminata, M. paleacea subsp. paleacea, M. polymorpha, M. treubii, and Marchantia sp. The most widely distributed species of Marchantia is M. emarginata subsp. cuneiloba, found in 7 study locations. Species with the least distribution are M. treubii and Marchantia sp., each species found only in one location. Marchantia spp. in North Sumatra spread at an altitude of 77 to 1976 m alt, occupying habitats with 6 types of soil (orthic acrisol, humic andosol, humic acrisol, and humic cambisol), with rainfall of 1800-3600 mm/year. Marchantia species are found on sloping plains to steep, in various habitat, namely secondary forest, primary and secondary forest borders, dryland farming, primary and plantation borders, and plantations. The results of this study are important for the conservation of Marchantia spp. in North Sumatra considering the many benefits of the species.

Abstract Bacterial key species (BKS) is unique and found only in peat secondary forest, but not in converted peat areas. Its presence helps in biomonitoring of peatland quality. BKS candidates were detected based on the 16S rRNA gene sequence using the Next Generation Sequencing method. The 16S rRNA gene sequencing data were obtained from DNA isolated from peat soil of the secondary forest (SF), acacia plantations (AP), and rubber plantations (RP) in the Giam Siak Kecil - Bukit Batu (GSK-BB) Biosphere Reserve, Riau. The natural vegetation of peat swamp forest dominates the SF, which was relatively heterogeneous with anaerobic conditions and water level at 60-120 cm. The RP locations were planted with 6-7 year old rubber, water level was 20 cm, and the garden was not maintained. The AP locations were planted with A. crassicarpa and peat thickness was 9 m. The peat soil was sampled in August 2019. BKS candidates were selected based on a phylogenetic tree using MEGA 6.06 by observing the grouping of DNA sequences obtained only from secondary forests. Furthermore, the selection was also conducted using BLASTn: Align Two or More Sequence analysis to determine the similarity between selected BKS candidates. Based on the detected BKS candidate, a specific primer was designed to amplify the BKS sequence, and the specificity was tested in silico with FastPCR to detect that the primer was only for the amplification of the BKS target. Two BKS candidates with the same sequence length of 455 bp were discovered in the secondary forests and there were successfully amplified by 2 pairs of specific primers. The 16S rRNA gene sequences of the two BKS candidates could be used to monitor the peat quality that has been converted into plantation areas molecularly.

Johannesteijsmannia altifrons, a palm species exhibits unique dispersal mechanisms and distribution patterns that are critical to understanding its ecological dynamics. Dispersal has a significant impact on this species' spatial distribution and population dynamics. The distribution is significantly influenced by altitude, which affects its growth and habitat suitability. Publications and references in this analysis came from scientific articles published in bibliographic databases such as Scopus and Google Scholar. The keyword search used was “Johannesteijsmannia altifronsâ€. The authors examined the literature related to the subject of the systematic review, assessed methodological rigor, analyzed the results being reported in the selected studies. Condensed and organized the data before incorporating the findings into a comprehensive systematic review in narrative form. The distribution of J. altifrons in Indonesia is mainly in the Sumatra region, especially in the Northern and Central parts of the island. Taman Nasional Gunung Leuser (TNGL), Bukit Bungkuk Nature Reserve Forest and the surrounding lowland forests are good habitats. This species has habitat suitability at range elevations 20-500 meters (asl), very steep slopes (≥ 45%). Optimal growth occurs under tree canopies, which provide the necessary shade for the plant to thrive. This suggests a specific habitat preference that influences its distribution

AbstractIn 1994 Alan Rabinowitz decried what he regarded as lackadaisical attempts by governments, NGOs and international funding agencies to conserve the Sumatran rhinoceros Dicerorhinus sumatrensis. Sixteen years on it is timely to evaluate whether his warnings were heeded. We review the current conservation status of D. sumatrensis throughout its range and the latest threats and challenges complicating efforts to conserve this species. Recent data from governments, NGOs and researchers indicate that the global population could be as low as 216, a decline from c. 320 estimated in 1995. Based on lessons learnt and expert opinions we call on decision makers to focus on two core strategies for conservation of D. sumatrensis: (1) the translocation of wild individuals from existing small, isolated or threatened forest patches into semi-in situ captive breeding programmes, and (2) a concomitant enhancement of protection and monitoring capacities in priority areas that have established these breeding facilities or have recorded relatively high population estimates and track encounter rates. At least USD 1.2 million is required to implement these strategies annually in four priority areas: Bukit Barisan Selatan and Way Kambas National Parks on Sumatra, and Danum Valley Conservation Area and Tabin Wildlife Reserve on Sabah. Given that conservation funds are rarely secure and D. sumatrensis is still in decline we call on potential donors to help secure and augment existing capacities of organizations in these four priority areas before committing resources to elucidate the status of the species in other areas such as Gunung Leuser and Taman Negara National Parks.

Full textAbstract:
Volant and non-volant small mammals from three forest reserves, located inside and outside Selangor State Park, Malaysia, were trapped and documented. A total of five-line transects, each 200 m long and a total of 100 collapsible cage traps, three harp traps and ten mist nets were deployed at each study site to capture rodents and bats species. The presence of 47 species of volant and non-volant mammals was documented with the highest abundant species being Leopoldamys sabanus (n = 61). The Family Vespertilionidae was the most diverse, while Muridae was the most abundant species. Diversity indices have shown forest reserves - Gading Forest Reserve (FR) and Bukit Kutu FR – located in the State Park, have a higher species composition than the impaired adjacent forest reserve, Bukit Tarek FR extension. The taxonomic diversity and taxonomic distinctness of the three forest reserves ranged between 2.433 and 2.610, while the taxonomic distinctness values ranged between 2.638 and 2.748. Even though Gading FR recorded the highest number of species diversity, the Chao 1 diversity estimator and the rarefaction accumulation curve indicated that Bukit Kutu comprised more species. Comparisons between other state parks and national parks in Peninsular Malaysia indicated that Selangor State Park indeed harbours relatively more species of small mammals. Northern Selangor State Park and adjacent forest should be recognised as a conservation priority area, although there are comparatively more species harboured in other regions of the State Park. With the current information on fauna diversity, proper management should be formulated to preserve the existing ecosystems in order to ensure the continuity of fauna diversity in Malaysia.

The Bukit Rimbang Bukit Baling Wildlife Reserve has unique species and diverse animals whose populations and habitats need to be protected. The location of the reserve also serves as a source of water for the community and prevents floods, landslides, and erosion. Before designation as a wildlife reserve, the forest served as a source of livelihood in the community, which helped manage and preserve conservation areas. The selected respondents were 35 heads of families, Information was obtained using the participatory rural appraisal (PRA) approach. The PRA results were tabulated and an estimate of willingness to pay for environmental ecosystem services was calculated. The economic value was calculated by summing up all the benefits identified from the ecosystem and the commodities utilized. This study aimed to determine the valuation of use and economic value based on non-use value. The results showed that the wildlife reserve area has the potential for economic value that may benefit the surrounding community and create environmental balance through river utilization and using non-timber forest products. There is increased income level, occupation, and environmental quality. Moreover, the potential use of non-timber forest products is an economic alternative to the community. The area has the potential to develop natural tourismas a learning process for future generations.
