Probability of Brazilian cottontail using sites increases with native forest cover and decreases with farmhouse proximity. Increased human proximity to tropical forests and tropical deforestation are currently more relevant threats to the conservation of the Brazilian cottontail in southeastern Brazil than the European hare invasion.
