Abstract | The hispid hare (Caprolagus hispidus) is one of the most elusive mammals and is listed as an endangered species both globally by the International Union for Conservation of Nature (IUCN) and nationally by National Red list series, Nepal. The species is experiencing a continuous decline across its distribution range due to increasing anthropogenic activities in its habitats. Limited information on the species distribution and the factors affecting its habitat use have restricted site-specific conservation actions. In this study, we aim to identify the current distribution pattern, factors associated with the habitat use of the hispid hare, and prevalent conservation threats in Shuklaphanta National Park (ShNP) of Nepal. We conducted a strip transect-based survey in January and February 2021 across 12 sampling grids of 0.5 km × 0.5 km. The presence of hispid hare was assigned to 1 if any indirect sign of its presence was observed “used plots,” otherwise to 0 if any indirect sign of its presence was not observed (“habitat availability plot”). We next measured six habitat predictors (i.e., nearest distance to a water source, ground cover, ground condition, habitat type, dominant plant species, and presence/absence of anthropogenic disturbance) from both types of plots (“used” and “habitat availability plot”). We found that the overall distribution of hispid hare was clumped. Confirming a new distribution location around the Baba Tal area in ShNP will alert conservation managers to the need of a rapid assessment of its presence–absence across the lowlands of Nepal. Except for the nearest distance to a water source, all other five habitat factors influenced the probability of encountering a hispid hare. Out of six threats, four threats (i.e., grassland burning during the breeding season, grassland succession, habitat loss and fragmentation, and thatch collection from woodland) were determined as the most severe for the hispid hare. Our findings will enable park managers and local government to formulate and plan suitable conservation measures to protect this threatened and endangered species and its habitats. In addition, our results will act as a baseline for further research in ShNP and other similar regions. |
