Summary

These data are the results of surveys for the Shasta salamander complex (Hydromantes shastae, H. samweli, and H. wintu) conducted at 87 survey plots on the Shasta-Trinity National Forest from April 2019 to March 2020. Time- and area-constrained occupancy surveys were conducted at plots selected within high-priority areas identified by the U.S. Fish and Wildlife Service. There are additional surveys planned for future field seasons. As the Shasta Salamander is under review for listing under the Endangered Species Act, sensitive location information is restricted, and can be made available upon request by contacting the dataset point of contact.

Purpose

The purpose of this project was to increase survey effort in select areas designated by the U.S. Fish and Wildlife Service to increase information about the range and probability of occurrence of Shasta salamanders. In particular, we sought to: 1) Develop and implement a systematic survey protocol for Shasta salamanders. 2) Survey for Shasta salamanders in areas deemed high priority by the U.S. Fish and Wildlife Service (USFWS). 3) Estimate Shasta salamander probability of occurrence and detection probabilities under the protocol, and propose modifications to the protocol that will increase detection probabilities and survey repeatability. This information is required to inform U.S. Fish & Wildlife Service management activities; both to assess the potential effects of increasing the level of Shasta Lake on Shasta salamanders and to evaluate whether the species complex should be listed under the U.S. Endangered Species Act.
