ABSTRACT: Since 1983, snowshoe hare (Lepus americanus) abundance appears to have steeply declined in Wisconsin based on harvest and track reports from the Wisconsin Department of Natural Resources. Snowshoe hare distribution has also contracted along the southern periphery of its range as a function of both climate and habitat change. We investigated the differential habitat use of snowshoe hare and the eastern cottontail (Sylvilagus floridanus) as part of a long-term mortality study in northern Wisconsin. Lagomorphs were live-trapped and fitted with VHF radio collars at two Northland College properties (Ashland County, WI, USA). Live-trap success and radio telemetry data were used to assess species-specific habitat preferences. Habitat characteristics between successful trap sites and telemetry locations were compared with unsuccessful trap sites using logistic regression analysis. The preliminary results of this research provide the foundation for examining how competition for localized habitat between snowshoe hare and eastern cottontail may influence the future survival of this species along its southern range boundary.
