Using Satellites to Forecast Impacts of Climate Change on Trout

Submitted by Anonymous (not verified) on

Population viability analysis (PVA) is a modeling tool used to predict the probability that a population will persist under projected future conditions. A new study funded by NASA will develop methods to link PVA to spatial and temporal environmental variation data derived from data collected by NASA satellites. This project is a collaboration between the USGS, the University of Georgia, University of Montana, Trout Unlimited, University of Nevada-Reno, and the U.S. Forest Service. Initial tests of this approach are focused on threatened Lahontan cutthroat trout in the Great Basin and will be extended to include additional trout species across the West. Results will inform conservation planning and management by making quantitative estimates of viability broadly available through a publicly accessible web interface.
