Table 5. Protected area resistance statistics for nine wildlife species in New England, USA.
Species | Marginal probability of resistance | Joint probability: resistant & protected | Joint probability: not resistant & unprotected | Conditional probability of protection given resistance | Conditional probability of resistance given protection |

All statistics were calculated using species binary resistance maps developed for the region and polygons from the Protected Areas Database of the U.S. (PAD-US version 2.0) [28]. Statistics include 1) Marginal probability of resistance: the proportion of the region that is resistant for each species, 2) Joint probability—resistant and protected: the proportion of the region that is both protected and resistant, 3) Joint probability—not resistant and unprotected: the proportion of the region that is unprotected and does not meet the resistance criteria, 4) Conditional probability of protection given resistance: the proportion of each species regional resistance that is protected, and 5) Conditional probability of resistance given protection: the proportion of the protected network that is resistant for each species. Note that the protected network covers 21.63% of the New England region (i.e., marginal probability of protection = 0.2163).
