Shasta Salamanders Survey Results for the Shasta-Trinity National Forest, 2019-2020 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.

The greatest threat to the species is likely habitat loss that will be caused by the increase in elevation of Shasta Lake that will occur with proposed increases in the height of Shasta Dam to increase water storage capacity and maintain cold water for Chinook salmon (Oncorhynchus tshawytscha). Another potential threat is the fungus Batrachochytrium salamandrivorans, which has not yet been detected in North America but is lethal to related salamanders (Hydromantes strinatii) in Europe (Martel et al. 2014). In addition to these threats, recent genetic evidence suggests that the species as originally petitioned...

The data also includes estimates of plot-level topography (slope, aspect), relativized differenced normalized burn ratio (RdNBR), post-fire climate, live basal area, and seed rain.
