Microhabitat Comparison of Swamp Rabbit Sites Between Periphery and Core of the Species Range

摘要

Swamp rabbits (Sylvilagus aquaticus) inhabit bottomland hardwood forests and rely on key microhabitat features found in this forested wetland system. Research comparing key features of swamp rabbit habitat across the species' geographic range is lacking. In this study, we compared 13 microhabitat characteristics at sites associated with 2 distinct behaviors (form and latrine) of swamp rabbits at the northern extent of their distribution (southwest Indiana, northwest Kentucky) with sites from the species' core distribution (Arkansas). There were significant differences in vegetation structure including canopy cover, basal area, stand density, and stem density between Indiana, Kentucky, and Arkansas sites for both form and latrine locations. At the northern periphery, where swamp rabbit populations are of conservation concern, we found that habitat is composed of fewer key components that are ecologically important to swamp rabbits such as canopy gaps, downed woody material, and cover. Wildlife managers interested in providing swamp rabbit habitat should recognizemicrohabitat components (i.e., canopy gaps, downed woody material) that are favorable for swamp rabbits and attempt to supply these elements through management actions such as uneven-aged silvicultural practices.
