The Vulnerable red panda Ailurus fulgens is endemic to the Himalayas. Anthropogenic activities, including deforestation, have degraded the species' habitat but the effects of livestock have not been examined. We assessed the effects of illegal livestock activity on the presence of the red panda in Rara National Park, Nepal. The probability of detecting red panda faecal pellets decreased with livestock occurrence but not with elevation or aspect. The presence of bamboo and proximity to water are important to red pandas but did not influence their habitat use at the spatial resolution evaluated. Livestock grazing in Rara National Park appears to adversely affect the presence of the red panda within its habitat. To reduce illegal livestock grazing we recommend enforcement of existing regulations, that training workshops be held for herders, and awareness-raising and dialogue with residents.Keywords Ailurus fulgens, conservation, grazing, habitat, Nepal, red panda, threatened species T he red panda Ailurus fulgens, endemic to the Himalayan areas of Bhutan, China, India, Myanmar and Nepal (Roberts & Gittleman, 1984), inhabits evergreen, deciduous, and mixed evergreen-deciduous forests with dense understories (Yonzon & Hunter, 1991) at elevations of 1,500-4,800 m (Choudhury, 2001). Red pandas require fallen logs for resting and feeding, bamboo or fruits for forage, and open water (Wei et al., 2000). The red panda is categorized as Vulnerable on the IUCN Red List (Wang et al., 2008) and in Nepal is a protected priority species (Jnawali et al., 2011) under the National Parks and Wild Conservation Act 1973. Range-wide threats include killing by poachers and dogs, and habitat loss (Wei et al., 1999;Williams, 2003). Livestock grazing and collecting livestock feed (Sharma & Belant, 2010) may further reduce the quality of habitat for the red panda. Understanding habitat selection by the red panda, especially any effects of anthropogenic activities on such selection, is important for the conservation of the species.Livestock grazing is considered a major threat to wildlife in protected areas in Nepal, including in Langtang National Park, Dhorpatan Hunting Reserve and Koshi Tappu Wildlife Reserve (Berkmueller et al., 1990;Yonzon & Hunter, 1991;Sharma & Belant, 2010), and elsewhere (e.g. Bhutan; Dorji et al., 2012). Livestock, particularly cattle and buffalo, can damage habitats, compete with native species for food and introduce diseases (Jolles et al., 2005;Schmidt et al., 2005). Consequently, we considered it relevant for red panda conservation generally to assess the effects of livestock use on red panda habitat selection in Rara National Park.We collected data on presence of livestock sign and red panda faecal pellet groups in Rara National Park ( Downloaded from https://www.cambridge.org/core.
