Spatially explicit abundance estimation of a rare habitat specialist: implications for SECR study design
Thea V. Kristensen, Adrienne Kovach
While the introduced eastern cottontail (Sylvilagus floridanus) is common in New England, the native New England cottontail (Sylvilagus transitionalis) is in decline. Estimating abundance is an essential component of monitoring and recovery of rare species. We obtained the first mark–recapture density estimates for the New England cottontail using spatially explicit capture–recapture (SECR) models and developed a sampling design that will be used in throughout the species’ range to monitor abundance and evaluate success of management practices.
