Many oak woodlands appear to be at risk now or will be within the next one or two decades. Table 1 . Natural communities identified as at risk by using Gap Analysis Program criteria. The list is ordered from highest to lowest percentage of the community that occurs on Level 3 private lands. Wildlife Status Detailed field-based maps of the distribution of wildlife do not exist for all species and would be too difficult to compile in the time available.
Biologists do know, however, what habitats most wildlife species prefer.
These predictions do not guarantee that a species occurs at a given location, only that suitable habitat exists. We used this proportion as our criterion for identifying what other species breeding in the region are at highest risk. Basically, the number of at-risk species is relatively uniform throughout San Bernardino, western Riverside, San Diego, and eastern Orange counties. Wildlife species considered at risk based on Gap Analysis Program criteria. Merriam's kangaroo rat Future Plans and Concerns Implementation of protective measures should occur soon.
