Landscape predictors influencing livestock depredation by leopards in and around Annapurna Conservation Area, Nepal

PeerJ, Journal Year: 2023, Volume and Issue: 11, P. e16516 - e16516

Published: Dec. 13, 2023

Livestock depredation by leopards is a pervasive issue across many Asian and African range countries, particularly in around protected areas. Developing effective conflict mitigation strategies requires understanding the landscape features influencing livestock depredation. In this study, we investigated predictors associated with using 274 cases of leopard attacks on that occurred between 2017 2020 Annapurna Conservation Area, Nepal. We also examined how predation varied depending species, season, time. A generalized linear model binary logistic regression was used to test statistical significance variables presence absence sites. The results revealed area forest, agricultural land, length rivers, slope, proximity settlements areas, elevation significantly predicted probability livestock. observed significant increase incidence decreasing slopes rising elevations. areas near human faced higher risk predation. Goats were most highly predated livestock, followed sheep, cow/ox, buffalo. total 289.11 km2 (or 5% research area) deemed be at high for This study's comprehensive human-leopard conflicts provides valuable insights planning implementing measures reduce damage caused populations throughout their range.

The Recolonisation of the Piketberg Leopard Population: A Model for Human–Wildlife Coexistence in a Changing Landscape

Conservation, Journal Year: 2024, Volume and Issue: 4(2), P. 273 - 287

Important metapopulation dynamics are disrupted by factors such as habitat loss, climate change, and human-induced mortality, culminating in isolated wildlife populations threatening species survival. Source populations, where birth rates exceed mortality connectivity facilitates dispersal, contrast with sink outstrips births, risking localised extinction. Recolonisation individuals from source is pivotal for The leopard the last free-roaming apex predator South Africa plays an important ecological role. In Eastern Western Cape provinces Africa, have low densities fragmented population structures. We identified a that, after being locally extinct century, appeared to recolonise ‘island’ of mountainous habitat. aimed understand potential driving this recolonisation using recent camera trapping surveys historical statutory destruction permits. employed spatially explicit capture–recapture (SECR) methods estimate density explore which best explain density. found that recently recolonised Piketberg now exhibits some highest reported region (~1.8 leopards/100 km2; CI 1.4–2.5).

When considering historic data, re-emergence leopards coincided cessation extensive state-sponsored state-enabled culling species, change land use livestock production crop agriculture, likely contributed recolonisation. Elucidating these deepens our understanding relation management highlights crucial role private state agencies associated policies persistence.

Current and future predicted distribution of roosts of the Indian Flying Fox Pteropus medius Temmink, 1825 in Nepal

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

The Indian Flying Fox Pteropus medius, largest of the four fruit bat species in Nepal and is extensively distributed South Asia. Their known roosts are within an elevation range 75 to 1,322 m asl east west Tarai, Chure, Inner-Tarai central Middle Mountains regions country. In Nepal, pollinate disperse seeds more than 26 families flowering plants. Most lie close vicinity urban land agricultural areas. Recently, impacts global warming on roosting foraging habitats bats including flying foxes have been evidenced different parts globe, however, it still unknown Nepal. addition, most colonies P. medius outside protected areas vulnerable due greater threats. To assess habitat suitability, we deployed Maximum Entropy modelling using 44 geo-referenced occurrence coordinates 11 bio-climatic variables use cover data layer with low inter-correlation (r > 0.75). current potential distribution covers area 16,642 Km² (about 11.3% country’s total area). influencing predictors for suitability identified as; land, water source Annual Mean Temperature. Our model projects that majority (99%) will remain suitable future, although expand lower elevations Chure regions. A shift towards northern latitude higher not anticipated. It imperative record sites better predict fox future. Since settlements farmlands, our finding can be utilized regular surveillance monitoring from health perspective. Conservation efforts should focus conservation source, plantation tall broad canopy trees safeguard existing prevalence warming.
