Popis:	We re-evaluate the distribution of the swamp rabbit (Sylvilagus aquaticus) in Southeast Missouri. We developed a list of 276 sites that were identified by the Missouri Department of Conservation as potential swamp rabbit habitat. Most of these sites were surveyed initially in 1992. We visited 245 of these sites in an effort to establish the presence or absence of swamp rabbits. Presence of swamp rabbits was based on scat deposition on down logs or stumps, presence of skulls or carcasses, sightings of live swamp rabbits, reports by trappers, or kills made by hunters. Logistic regression analysis was used to quantify the relationship between site area and likelihood of swamp rabbit presence. A patch size of approximately 48.6 ha was required to ensure a 50% likelihood of swamp rabbits in 1992, whereas in 2001 only 40.5 ha were required. No significant improvement in the distribution of swamp rabbits has occurred in Missouri since 1992.
