A Framework for Categorizing the Relative Vulnerability of Threatened and Endangered Species to Climate Change (External Review Draft)

The framework presented in this report may be used to categorize the relative vulnerability of species to climate change. There are four modules that compose this framework. These modules walk the user through a systematic process for (1) categorizing a species’ baseline vulnerability to extinction or major population reduction, (2) categorizing a species’ vulnerability to future climate change, (3) developing a matrix that provides an overall score of the species’ vulnerability to non-climate and climate change stressors, and (4) qualitatively determining the uncertainty in the estimate of a species’ vulnerability.

This framework is not intended to serve as a tool for determining whether a species is endangered or threatened under the Section 4 listing process of the Endangered Species Act, but rather to provide information to resource managers to help guide management decisions related to threatened and endangered species.

The framework in this report was developed by Hector Galbraith of Manomet Center for Conservation Sciences and Jeff Price of World Wildlife Fund. Review, comments, and general oversight of this work were provided by the Global Change Research Program (GCRP) in the National Center for Environmental Assessment (NCEA), U.S. Environmental Protection Agency (U.S. EPA).
