Abstract: We studied habitat selection of Reeves's muntjacs (Muntiacus reevesi) and wild boars (Sus scrofa) in Qingliangfeng Nature Reserve in northwestern Zhejiang, China. Habitat characteristics were measured on the basis of expected differences between species at 248 sites from 5 November 2005 to 21 January 2006. Habitat selection showed a certain extent of overlap, muntjacs and wild boars both selected habitats with shrub vegetation, low herbage density, gentle slopes, relatively close to residences, and moderate concealment. Differences in habitat selection were that muntjacs selected habitats with moderate tree density, greater shrub density and moderate canopy, whereas wild boars selected habitats with lower tree density. Muntjacs selected north-facing slopes and habitats distant from water-sources, whereas wild boars displayed noselection with regard to slope or distance from water sources. We suggest that the two species coexist in Qingliangfeng as a result of differential habitat selection associated with their species-specific anti-predator strategies. Muntjacs avoid predators by concealment whereas wild boars evade predators by running as their escape strategy.
