The Endangered Indian pangolin Manis crassicaudata, a burrowing, armoured mammal, plays an important role in the food web by consuming insects and termites. In Pakistan the species’ range includes the 22,000 km2 Potohar Plateau, where it is under pressure from illegal hunting for its scales and requires conservation attention. We used a geographical information system to quantify the range of the Indian pangolin on the Plateau and to compare this with the range estimated in the IUCN Red List assessment of the species. We found that the species occupies c. 89% of the Plateau, in eight of the 10 protected areas, compared with the IUCN estimate of 71%, and we recorded the species at 40 locations on the Plateau outside the range predicted by the IUCN assessment. We collected data on the illegal capture and killing of the species, recording 412 individuals that had been killed at 48 locations between January 2011 and the end of April 2013. The highest number of killings was recorded in Chakwal District (n = 156, at 13 sites) followed by the Attock District (n = 149, at eight sites). Although the Indian pangolin's range on the Potohar Plateau is c. 18% larger than that estimated in the IUCN assessment, the species is under pressure from illegal killing and requires urgent conservation measures to save the small remaining population and avoid the extirpation of this vital insectivorous predator from the area.
Ecosystem functioning is dependent a lot on large mammals, which are, however, vulnerable and facing extinction risks due to human impacts mainly. Megafauna of Asia has been declining for a long, not only in numbers but also in their distribution ranges. In the current study, we collected information on past and current occurrence and distribution records of Asia’s megafauna species. We reconstructed the historical distribution ranges of the six herbivores and four carnivores for comparison with their present ranges, to quantify spatially explicit levels of mega-defaunation. Results revealed that historically the selected megafauna species were more widely distributed than at current. Severe range contraction was observed for the Asiatic lion, three rhino species, Asian elephant, tigers, and tapirs. Defaunation maps generated have revealed the vanishing of megafauna from parts of the East, Southeast, and Southwest Asia, even some protected Areas losing up to eight out of ten megafaunal species. These defaunation maps can help develop future conservation policies, to save the remaining distribution ranges of large mammals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
