Naïve occupancy estimates were calculated by methods presented in MacKenzie et al. (2002), and represent the proportion of total sites at which a species was detected. Occupancy and detection estimates presented are the transformed beta estimates from the null model [Ψ(.) p(.)].

aThe proportion of sites a species was actually detected

bOccupancy probability–the estimation of the proportion of sites occupied, given the detection history of a species.

cDetection probability–the probability of detecting a species, given it is present.

dStandard Error of detection probability estimates.
