资源简介：
Data will be collected on population size and habitat use of California Red-legged Frogs, Rana draytonii, in the presence and absence of the invasive bullfrog, Rana catesbeiana. Visual and audio encounter surveys will be conducted day and night, biweekly, from March until October, to observe every life stage of R. draytonii. Adults encountered will be sexed, measured, and weighed. Abundances and locations of egg masses and larvae will also be documented.
