In contrast to <7% natural forest covers and >1,000 people living km-2, Bangladesh, one of the smallest countries in Asia, shelters 28 carnivorous mammals. The species are six families, nearly half entire carnivore diversity Indian Subcontinent. Carnivores Bangladesh little understood they disappearing fast despite receiving stern protection. Yet, there has been no assessment on status existing knowledge. A review was aimed assess knowledge evaluate research trends country’s mammalian carnivores.

Seasonal Prey Abundance and Food Plasticity of the Vulnerable Snow Leopard (Panthera uncia) in the Lapchi Valley, Nepal Himalayas

Animals, Journal Year: 2023, Volume and Issue: 13(20), P. 3182 - 3182

Published: Oct. 12, 2023

Conservation strategies for apex predators, like the snow leopard (Panthera uncia), depend on a robust understanding of their dietary preferences, prey abundance, and adaptability to changing ecological conditions. To address these critical conservation concerns, this study presents comprehensive evidence availability preferences leopards in Lapchi Valley Nepal Himalayas from November 2021 March 2023. Field data were collected through installation twenty-six camera traps at 16 strategically chosen locations, resulting recording 1228 events 19 mammalian species, including domesticated livestock. Simultaneously, collection twenty scat samples over 3800 m above sea level allowed detailed analysis. Photo capture rate index biomass composition analysis carried out seasonal consumption statistically analyzed. A total potential species documented during period. Himalayan musk deer (Moschus leucogaster) was most abundant but infrequent diet suggesting that are not best bet leopards. Snow found exhibit diverse diet, consuming eleven with blue sheep (Pseudois nayaur) being consumed wild horses as preferred The Pianka’s niche overlap between summer winter seasons 0.576, pronounced variation food preference corroborating availability. scarcity larger preys is compensated by small meso-mammals highlighting leopard’s capacity plasticity response resource This research suggests utilization genetic tools further explore composition. Additionally, transboundary movements conducting population assessments will be imperative formulation effective strategies.

Status and conservation threats to large mammals of the Laljhadi Mohana Biological Corridor, Nepal

Journal of Animal Diversity, Journal Year: 2020, Volume and Issue: 2(2), P. 16 - 33

Wildlife corridors connect isolated patches of habitat and support the movement migratory species from one site to another.Human disturbances cause forest degradation fragmentation adding high risk extinction.We laid out 44 grids 2 km × in Laljhadi Mohana Biological Corridor (LMBC).In each grid, we generated line transects ranging 1.5 a systematic transect survey was carried with single replication assess distribution relative abundance large mammals.GPS coordinates were recorded for direct sighting or indirect sign.Similarly, local household (n=40) key informant interviews (n=9) conducted explore perception about existing problems, major conflicting components, conservation threats attitude towards mammals.A workshop also held discuss information species, possible solutions, ranking based on system.A total 51 individuals belonging six mammals found LMBC.Distribution primarily confined south corridor, abundance, descending order, is Blue bull (29.4%),Asian elephant (25.5%),Spotted deer (21.5%),Wild boar (15.7%),Common leopard (5.9%) Bengal tiger (2%).Major encroachment (Very High), followed by grazing product consumption (High), natural disaster (Medium) illegal poaching, infrastructure construction, invasive (Low).The LMBC mammals, where mostly Asian elephants are using it migration.

Published: Feb. 15, 2024

Sloth bears (Melursus ursinus) are listed as Vulnerable on the International Union for Conservation of Nature (IUCN) Red List threatened species with a global population estimate <17,000 individuals. In southwestern Nepal, Shuklaphanta National Park includes largest uninterrupted expanse grassland in region and provides suitable habitat sloth bears. No records from Park, however, have been reported since 2013. We present first photographic evidence bear decade. addition, we observed Bengal tiger (Panthera tigris tigris) at same location 5 days later. These observations highlight need further research into occurrence movements this well extent co-occupancy types interactions between tigers.

Diversity of mammalian species in the Kangchenjunga Landscape of eastern Nepal

European Journal of Wildlife Research, Journal Year: 2024, Volume and Issue: 70(6)

Published: Nov. 7, 2024

The Himalayas, including Nepal, are a biodiversity hotspot. However, records on mammalian richness remain incomplete due to resource limitations, inadequate training, and the remote location of study areas. unprotected forest area Panchthar-Ilam-Taplejung region in eastern Nepal is vital corridor connecting India Nepal. Using structured methodology we aimed increase our knowledge diversity this area. Camera traps were deployed throughout 53 locations winter 54 spring, accumulating 3014 camera trap days generating 93,336 images, with positive trigger rate 29.8%. survey revealed 17 species medium large-sized mammals an additional six smaller unidentified mammals, two melanic variations previously undocumented species. Activity patterns calculated for more than five image both seasons. findings contribute essential information about Kangchenjunga Landscape, which can be used further conservation efforts critical ecosystem corridor.

Abstract The Vulnerable clouded leopard Neofelis nebulosa is believed to be one of the most threatened felid species in Nepal. Information on its status and population size country mostly comprises crude estimates. We compiled information species’ distribution from published papers, grey literature, camera-trap images, direct observations, pelt, zoo museum records, wildlife seizures verified newspaper reports. All confirmed records (three specimens, dead specimen, 13 live (including camera traps), 14 pelts) were eastern mid-central Two unconfirmed reports western far-western regions need verified. Although still uncertain, frequency extent area occurrence indicate that it not as rare previously assumed. main threats are habitat loss illegal trade.

The present crisis, including burgeoning effects climate change, therefore, has warranted restoration actions place. Conservation translocation, one effective measures restoration, involves individuals species deliberate movement from habitat to another, particularly animal species. Nepal practicing conservation translocations for more than four decades. However, details translocation events outcomes not well documented. This article aims explore status issues Nepal. For purpose, we reviewed seven protected area management plans nine action available public domain along with related peer journal articles.
