Abstract Conservation of habitat fragments, including those embedded in an urban matrix which typically support fewer species than those in other landscape contexts, is important for combatting the global extinction crisis. Because urban avoiding species are often absent from habitat fragments within an urban matrix, studies of their distributions in these habitats are rare, and therefore the mechanisms by which species are excluded from habitat fragments within an urban matrix are poorly understood. We investigated the impacts of urbanization in the matrix (e.g., noise pollution, light pollution, invasive species) on the distribution of an urban avoiding species, the swamp rabbit (Sylvilagus aquaticus) in the largest urban forest fragment in the United States. We used the location of swamp rabbit latrines and presence‐background species distribution modeling to reveal the impacts of urbanization in the matrix on swamp rabbit distribution while accounting for spatial heterogeneity in naturally occurring environmental variables. Swamp rabbits used mature forest, heterogeneously structured forest, and moderately inundated forest, and they avoided areas of high (Sus scrofa) hog activity at our study site. Our findings provide novel information to conservation practitioners and urban planners attempting to conserve high priority species in habitat fragments as urbanization continues to spread.
