AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of public comment period.

SUMMARY:

EPA is announcing a 30-day public comment period for the draft document titled, “A Framework for Categorizing the Relative Vulnerability of Threatened and Endangered Species to Climate Change” (EPA/600/R-09/011). The document was prepared by the National Center for Environmental Assessment within EPA's Office of Research and Development. This draft document describes an evaluative framework that may be used to categorize the relative vulnerability of species to climate change. To illustrate the use of this framework, it was applied to five U.S. threatened and endangered species: The golden-cheeked warbler, the salt marsh harvest mouse, the Mount Graham red squirrel, the Lahontan cutthroat trout, and the desert tortoise. A sixth species, the bald eagle which is no longer listed as threatened or endangered, except for the southwest population, was also evaluated.

An external peer review of this report has been completed. The public comment period and the external peer review are separate processes. The public comment period provides an opportunity for all interested parties to comment on the document. When finalizing the draft document, EPA will consider any public comments received in accordance with this notice.

EPA is releasing this draft document solely for the purpose of pre-dissemination review and comment under applicable information quality guidelines. This document has not been formally disseminated by EPA and does not represent and should not be construed to represent any Agency policy or determination. The first draft of this report was reviewed in 2002 by the U.S. Fish and Wildlife Service within the Department of the Interior. This final draft is being released to the public as well as to other federal agencies who may wish to comment.

DATES:

The 30-day public comment period begins November 25, 2009, and ends December 28, 2009. Technical comments should be in writing and must be received by EPA by December 28, 2009.

ADDRESSES:

The draft “A Framework for Categorizing the Relative Vulnerability of Threatened and Endangered Species to Climate Change” is available primarily via the Internet on the National Center for Environmental Assessment's home page under the Recent Additions and the Data and Publications menus at http://www.epa.gov/​ncea.

SUPPLEMENTARY INFORMATION:

I. Information About the Project/Document

The document, “A Framework for Categorizing the Relative Vulnerability of Threatened and Endangered Species to Climate Change” describes an evaluative framework that may be used to categorize the relative vulnerability of species to climate change. It is intended that the results of applying the framework be regarded as indications of the comparative vulnerabilities of species, not estimates of a species' absolute vulnerability to climate change. Four modules compose this framework: Module 1 categorizes baseline vulnerability to extinction or major population reduction by scoring those elements of the species' life history, demographics, and conservation status that influence the likelihood of its survival or extinction (excluding climatic changes); Module 2 scores the likely vulnerability of a species to future climate change, including the species' potential physiological, behavioral, demographic, and ecological response to climate change; Module 3 combines the results of Modules 1 and 2 into a matrix to produce an overall score of the species' vulnerability to climate change, which maps to an adjectival category, such as “critically vulnerable,” “highly vulnerable,” “less vulnerable,” and “least vulnerable;” Module 4 is a qualitative determination of uncertainty of overall vulnerability (high, medium, and low) based on evaluations of uncertainty done in each of the first 3 modules.

To illustrate the use of this framework, it was applied to six U.S. species that were listed as threatened or endangered at the time the framework was developed. Based on the framework, four of those species were categorized as “critically vulnerable” to climate change: The golden-cheeked warbler (Dendroica chrysoparia), the salt marsh harvest mouse (Reithrodontomys raviventris), the Mount Graham red squirrel (Tamiasciurus hudsonicus grahamensis), and the Lahontan cutthroat trout (Oncorhyncus clarki henshawi). The desert tortoise (Gopherus agassizii) was characterized as “highly vulnerable” and the bald eagle (Haliaeetus leucocephalus) was categorized as “less vulnerable.” Certainty scores in Module 4 ranged between medium and high and reflect the amount and quality of information available.

This framework was developed by EPA's Global Change Research Program and is offered as one of a number of potential approaches for prioritizing those species most vulnerable to climate change. It 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.

EPA's Global Change Research is an assessment-oriented program committed to developing frameworks and tools to assist decision-makers in evaluating the impacts of climate change to air quality, water quality and ecosystems.
