Metropolitan Water District Inland Feeder Project: Mountain Yellow-Legged Frog (Rana muscosa) and California Red-Legged Frog (Rana aurora) Surveys

摘要

Surveys were conducted along 10 drainages in the San Bernardino National Forest between June and August 2001. For several drainages, surveys were conducted along different reaches along the canyon (i.e. lower and upper portions) and were conducted on multiple occasions. Because surveys were conducted after the optimal season for which to document arroyo southwestern toad (Bufo californicus) and western spadefoot toad (Spea hammondii) activity (typically March-May), we present data specific to MYLF and RLF surveys only.
