As one of the four extant species of Asian pangolins, the Indian Pangolin Manis crassicaudata is the only species found in Pakistan that is enlisted endangered due to trafficking and illegal trade. The current study investigated the factors affecting pangolin presence in the ravine habitats of Margalla Hills National Park, Islamabad, Pakistan. Between May and June 2022, we conducted a sign survey based on the line transect method confirming species presence. In addition, 12 passive infrared motion-triggered cameras were also deployed for a total of 132 trap nights with only two captures at a single camera station. Among the 51 signs observed, 32 were burrows. Digging and pug marks were counted as 17 and two, respectively. Most burrows (97%) were categorized as inactive burrows, of which the pangolin used most (78.28%) for feeding. The statistical analysis showed that the nearest settlement does not impact the pangolin presence (p = 0.209). Roads were found to have a positive correlation with pangolin presence (p = 0.018), yet, agricultural lands were significantly avoided by the Indian pangolin (p = 0.001). Our results suggest that the Indian pangolin inhabit areas between forests and agricultural lands yet close to human settlements and roads. [ABSTRACT FROM AUTHOR]

Knowledge of a species' distribution is important for developing effective conservation programs. In Pakistan, little is known about the status or distribution of most carnivores coexisting in the same landscape. To address this knowledge gap, we studied distribution patterns of coexisting carnivores in Margalla Hills National Park, using both conventional as well as DNA-identified scats, and other signs. Although scat surveys remain a popular approach to study carnivores, scat identification based on morphology alone is error-prone. As part of our study, we therefore evaluated accuracy of morphological identification of scats using genetic techniques. Field surveys were conducted from September 2015 to December 2018. Using 593 direct (sighting, camera trapping, road kills) and indirect (scats, footprints) field signs, we detected total 11 carnivore species in the park, including 10 that were represented in the subset of 248 (47.7%) scats identified from DNA. The molecular analyses confirmed that the misidentification rate was highest for red fox (Vulpes vulpes) (8.47%), followed by Asiatic jackal (Canis aureus) (7.66%), but least for small Indian civet (Viverricula indica) (3.63%). For investigating habitat association of carnivores, and to test for the associations between species presence and Normalized Difference Vegetation Index (NDVI), we compared the mean and standard deviation of NDVI of each species' presence locations with the mean and standard deviation of NDVI along the 23 sampling transects. Based on DNA-verified and all scats, carnivore species showed a range of mean NDVI, suggesting, preliminarily, some species may utilize a greater diversity of habitat types than others.

Objective: Protected areas are of immense importance to enhance the functional role of plants due to abundance of woody species, their carbon sequestration ability and the rich organic matter and hence it needs to be documented and quantified scientifically with special focus on its carbon sink potential. Mathods: In this study, the Carbon sequestration, diversity and abundance of woody plants were evaluated in the Margalla Hills National Park (MHNP), Pakistan using quantitative and functional ecological approaches. We randomly sampled 40 (20 m × 20 m) plots from March, 2020 to March, 2021. PC-ORD version-5 and CANOCO software were used to evaluate relationships of different environmental factors with species composition, distribution pattern and other quantitative traits of forests. R program was used for regression and correlation analyses to model Carbon sequestration capacity of MHNP. Results: A total of 4916 individuals belonging to 49 species and 28 families were reported. The higher carbon sequestration was found in Albizia lebbeck 2620.75 lbs per year followed by Pinus roxburghii 2214.48 lbs and Castanea sativa 1731.59 lbs while the lower rate of carbon dioxide sequestration per year were found in Myrsine africana 1.81 (lbs) followed by Nerium oleander 2.84 (lbs) and Jasminum officinale 3.92 (lbs). The Two-way Cluster Analysis shows the distribution of species in the study area. The CCA analysis show that pH, EC, and TDS play a significant role in the distribution of woody plant vegetation. Carbon sequestration mainly depends on plant DBH, followed by plant crown. Conclusion: The results prove that the DBH has a leading role in the carbon sequestration rather than height of the woody species. The present study indicates the MHNP is a rich source of woody plant vegetation because of its conserve nature and plays a significant role in ecosystem stability and air quality, therefore, more studies are required to study other aspects of the woody plant vegetation in the MHNP.

We investigated the occurrence and diet of two sympatric mongoose species; the small Indian mongoose Urva auropunctatus and the grey mongoose Herpestes edwardsii inhabiting Margalla Hills National Park, Islamabad, Pakistan. The two species occurred in the park at elevations between 537 m and 1363 m a.s.l., with the grey mongoose occurring at higher elevations than the small Indian mongoose. Out of 23 sites sampled, only three were common to both mongoose species. The diet of mongooses, determined through food remains in scats, comprised of small mammals (rodents, shrews), insects, birds, reptiles and seeds and fruits. Rodents were the most frequently-consumed prey species of both mongooses during summer and winter, whereas insects were consumed more frequently during the summer. The small Indian mongoose showed a wider niche breadth than the grey mongoose, but the overall dietary overlap between the two mongoose species was high with a value of 0.93. Our results support the idea that these sympatric mongoose species may reduce interspecific competition for food with each other through spatial adjustments in their habitat use.
