ABSTRACT Using a geographic information system (GIS), we developed three models predicting the occurrence of swamp rabbits, Sylvilagus aquaticus, in western Kentucky. The models were compared to the existing Kentucky GAP model. All models were successful in the prediction of confirmed swamp rabbit observations, both of resence (> 80%) and absence (> 90%), with only slight variation among models. After selection of the best model based on statistical performance and model construction criteria, the best model was applied to geographic areas of Kentucky contiguous to the species' current Kentucky range to investigate the possibility of swamp rabbit reintroductions. Only five areas for potential reintroduction were identified, with two of marginal quality and the remaining unsuitable for swamp rabbit reintroduction. Land ownership and protection status of all habitat determined to be suitable by our best model was assessed; the vast majority of all land was in private ownership. Wildlife Management Areas (WMAs) protected the most swamp rabbit habitat (˜ 8%), but most suitable habitat remains at risk. These models can serve as a solid basis for future swamp rabbit management considerations. Field validation and frequent assessments and modifications of the models associated with increased data availability and improved GIS technology are recommended.
