SPACECAP is a user-friendly software package for estimating animal densities using closed model capture-recapture sampling based on photographic captures using Bayesian spatially-explicit capture- recapture models. This approach offers advantage such as: substantially dealing with problems posed by individual heterogeneity in capture probabilities in conventional capture-recapture anal- yses. It also offers non-asymptotic inferences which are more appropriate for small samples of capture data typical of photo-capture studies.
