Distribution of Sensitive Amphibians in the KRIS Mendocino Project Area

Amphibian Information in KRIS Ten Mile

California Department of Fish and Game memos, Humboldt State University (Kitchen, 1992) studies and University of California zoological samples confirm that tailed frogs and southern torrent salamanders were distributed throughout the KRIS Mendocino project area. Recent surveys of the Ten Mile River basin showed tailed frogs present at some sites surveyed from 1993-1999 (Ambrose and Hines, 1998). CDFG collections documented the existence of tailed frogs in a tributary to the North Fork of the South Fork Noyo River (Macedo, 2000). Kitchen (1992) documented that southern torrent salamanders occurred in Parlin Creek, in the South Fork Noyo basin (see note from Dr. Hartwell Welsh, USFS Redwood Sciences Lab).

Data from the Mattole Basin represent the best information available on known relationships of sensitive amphibians, riparian habitat change and changes in temperature regimes related to land use in northwestern California.
