Using elephant movements to assess landscape connectivity under Peninsular Malaysia's central forest spine land use policy

One of the most vital and urgent global conservation challenges is to deal with the loss and fragmentation of wildlife habitats, particularly for large‐bodied and wide‐ranging terrestrial megafauna. The Central Forest Spine Master Plan for Ecological Linkages (CFS) was developed by the Malaysian Federal Government in 2010 to protect biodiversity and ecosystem services by securing landscape connectivity between Peninsular Malaysia's main forest blocks. Here we present an evaluation of the effectiveness of the CFS master plan to promote functional connectivity for Asian elephants, one of its focal species. The specific objectives of our study were to identify the most critical forest patches to maintain connectivity for elephants in Peninsular Malaysia, assess functional connectivity within the CFS ecological linkages, and identify alternative corridors where appropriate to enhance CFS effectiveness. We used the largest animal movement dataset in Peninsular Malaysia (220,000 GPS locations from 53 elephants) to develop models of elephant movement probability and to estimate landscape resistance using step selection functions based on landscape characteristics. According to our evaluation of 28 linkages, 57% of them provided high functional connectivity, 28% provided acceptable connectivity, and 14% provided low to no connectivity. A very important and positive finding is that the CFS linkages with the highest centrality values (i.e., the most important to maintain overall connectivity in Peninsular Malaysia) also score highly in functional connectivity (i.e., they are actually effective corridors for elephant movement). This means that an adequate CFS implementation can lead to high levels of functional connectivity among Peninsular Malaysia's main forest blocks. Based on our assessment, we recommend to conduct some revisions on the CFS plan to ensure its effectiveness

Herpetofauna diversity in Sg. Deka, Hulu Terengganu, Peninsular Malaysia / Nur Amalina Mohd Izam

Sg. Deka is located in Tembat Forest Reserve (TFR), the largest forest reserve in Terengganu. Sg. Deka is known to have ecological bridges for wildlife crossings and serves as a corridor for wildlife to the national park. Sg. Deka is a protected area that serves as a wildlife release site and houses many species of fauna. This survey was conducted in Sg. Deka with the aim of determining the herpetofaunal diversity. The survey was conducted from August 2014 to July 2015. Fenced-pitfall traps and visual encounter survey method were used, as combination of various methods increases the chance to find more species in an area. A species diversity checklist of the herpetofauna in Sg. Deka is presented. A total of 119 herpetofauna individuals were found, comprising of 75 amphibians and 44 reptiles. This checklist includes 12 amphibian species from five families, namely Bufonidae, Dicroglossidae, Megophryidae, Microhylidae, and Ranidae; and 14 reptile species from four families, namely Agamidae, Gekkonidae, Scincidae, and Colubridae. The most dominant species found was Ingerophrynus parvus. Further surveys need to be carried out to discover more herpetofauna in Sg. Deka area

Assessing habitat requirements of Asian tapir in forestry landscapes: Implications for conservation

The iconic large-bodied Asian tapir (Tapirus indicus) is endemic to Southeast Asia and is currently listed as endangered. To date, little is known about how tapir respond to habitat fragmentation in forestry landscapes. This study aimed to assess tapir occurrence in eight forestry reserves, outside the main protected areas in Peninsular Malaysia, using non-intrusive camera trapping methods. These reserves include logged or unlogged, contiguous or fragmented, peat swamp forest and lowland dipterocarp forest. Out of 345 camera-trapping locations, over six years, we detected tapir at 39 locations, represented by 960 images. An assessment of vegetation structure and landscape variables was conducted to identify the key factors associated with their tapir presence. We found that tapir occurrence significantly increased with the number of trees with a DBH of 5–45 cm, number of saplings, percentage of canopy cover, trees with a DBH of more than 45 cm and distance from the nearest road. While, tapir detection decreased with the number of dead fallen trees and number of palms. Our data highlights the importance of conserving these remaining fragmented forest reserves, particularly peat swamp forests and ways in which suitable habitat conditions may be created to support tapir populations. We conclude by discussing intervention approaches such as relocation, reintroduction and restocking and restoration to improve the structural attributes of vegetation utilised by tapirs

L'approche par problèmes et par projets : effets de dispositifs pédagogiques actifs dans l'enseignement universitaire

Tropical forests across the world provide important habitats for a diverse number of conservation priority species, yet are under threat from a range of anthropogenic impacts including logging. This study aims to quantify mammalian biodiversity in unlogged and logged forests in the adjoining Tembat and Petuang Forest Reserves, Terengganu, on the East Coast of Peninsular Malaysia. Data was collected over a series of surveys using direct and indirect observation methods from 2008 to 2014. A total of 30 medium and large sized mammals species were identified, with 27 of those species found in unlogged forests and 22 species in logged forests. Carnivores encompassed 11 species from 67 observations representing 15% of the total number of observations. The family Felidae had the highest number of species (six species), followed by Hylobatidae, Cercopithecidae and Suidae with three species each. A total of 17 species contributed to more than 90% of the mammal community in the unlogged and logged forests, while six species were uncommon and only observed once during the entire survey. Species abundance in the unlogged forest was significantly greater than the logged forests, but the difference was not significant for species richness. This study provides critical baseline information on the impact of unlogged and logged forests and the identification of threatened species warrant the establishment of conservation measures such as anti-poaching patrol and ranger stations in the study area

Predicting the distribution of the Asian tapir in Peninsular Malaysia using maximum entropy modeling

In 2008, the IUCN threat status of the Asian tapir (Tapirus indicus) was reclassified from 'vulnerable' to 'endangered'. The latest distribution map from the IUCN Red List suggests that the tapirs' native range is becoming increasingly fragmented in Peninsular Malaysia, but distribution data collected by local researchers suggest a more extensive geographical range. Here, we compile a database of 1261 tapir occurrence records within Peninsular Malaysia, and demonstrate that this species, indeed, has a much broader geographical range than the IUCN range map suggests. However, extreme spatial and temporal bias in these records limits their utility for conservation planning. Therefore, we used maximum entropy (MaxEnt) modeling to elucidate the potential extent of the Asian tapir's occurrence in Peninsular Malaysia while accounting for bias in existing distribution data. Our MaxEnt model predicted that the Asian tapir has a wider geographic range than our fine-scale data and the IUCN range map both suggest. Approximately 37% of Peninsular Malaysia contains potentially suitable tapir habitats. Our results justify a revision to the Asian tapir's extent of occurrence in the IUCN Red List. Furthermore, our modeling demonstrated that selectively logged forests encompass 45% of potentially suitable tapir habitats, underscoring the importance of these habitats for the conservation of this species in Peninsular Malaysia

Diversity and Distribution of Primates in the Gunung Basur Permanent Forest Reserve

Abstract This paper presents data regarding the diversity, population density, and distribution of primate species within the Gunung Basur Permanent Forest Reserve (GBPFR). The survey was conducted from the 3rd–8th of November in 2019, covering 7 survey locations (Terang Pump House, Suda Intake, Renyok 1 Intake, Renyok 2 Intake, Renyok 3 Intake, Long Intake, and Long 2 Intake) within the reserve. A total of 36 hours was spent to perform random sampling observations. The focus of this survey was to identify diurnal primate species. A total of 5 species (Symphalangus syndactylus, Hylobates agilis, Presbytis siamensis, Trachypithecus obscurus, and Macaca nemestrina), belonging to the families Hylobatidae and Cercopithecidae, were observed during the survey period. The density of Trachypithecus obscurus was high at the study site, with 60 individuals identified, followed by Symphalangus syndactylus, with 45 individuals, Presbytis siamensis, with 39 individuals, Hylobates agilis, with 20 individuals, and Macaca nemestrina with only 3 individuals. Two of the identified species are classified as Totally Protected (Symphalangus syndactylus and Hylobates agilis), whereas the other 3 species (Macaca nemestrina, Presbytis siamensis, and Trachypithecus obscurus) as classified as Protected, according to the Wildlife Conservation Act 2010 (Act 716). According to the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, 2 species (Symphalangus syndactylus and Hylobates agilis) are considered to be Endangered, 2 species (Presbytis siamensis and Trachypithecus obscurus) are considered to be Near Threatened, and Macaca nemestrina is listed as Vulnerable. The data gathered from this study is crucial for designing a wildlife conservation plan for this reserve.</jats:p
