Once an abundant frog throughout much of central and southern California, the California red-legged frog (Rana draytonii) is now rare in the Sierra Nevada foothills and the southern portion of its range. In parts of the central Coast Range, however, large, vigorous populations do remain. Most protection efforts for this threatened species have focused on breeding sites. A scarcity of information on habitat use beyond the breeding site has made it difficult to evaluate requirements for non-breeding habitat and connecting migration corridors. Less...
