The Decline of Amphibians in California's Great Central Valley
Fisher RN and Shaffer HB. 1996. The Decline of Amphibians in California's Great Central Valley. Conservation Biology. 10(5):1387-1397
Broad-scale field sampling was combined with historical analyses of museum records to quantify amphibian declines in California's Great Central Valley. An unambiguous pattern of decline in amphibian species was shown. The intensity of decline varied both geographically and taxonomically. At lower elevations, native species were highly impacted; some had been restricted to higher elevation sites.
