Description
ABSTRACT. We used radio telemetry to estimate fall/winter home range size for five adult swamp rabbits (Sylvilagus aquaticus) in southwestern Indiana and northwestern Kentucky during the fall/winter months of 2007-2008, and compared that estimate to reported home range size estimates throughout the species' geographic range. Mean fall/winter 95% fixed-kernel home range size was 5.57 ha (SD = 3.91 ha) and 100% minimum convex polygon home range size was 2.98 ha (SD = 1.43 ha). Our estimate was smaller than previously reported in southwestern Indiana, but it was larger than other studies throughout the swamp rabbit's range. Differences among estimates may have been due to small sample sizes, methods used to calculate home range size, quality of habitat, and inclusion of locations during flood events. Daytime forms (n = 112) for eight rabbits included herbaceous vegetation (n = 28; 25.0%), brush piles (n = 27; 24.1%), cavities at the base of live trees (n = 17; 15.2%), downed hollow logs (n = 17; 15.2%), base of tree (n = 8; 7.1%) and miscellaneous (n = 15; 13.4%). Frequent use of cavities at the base of live trees is unusual and may be attributed to behavioral thermoregulation or insufficient brush cover. Our findings suggest natural resource managers in Indiana should pay careful attention to the quantity and quality of bottomland hardwood forest when evaluating swamp rabbit habitat.
