ENVIRONMENTAL PROTECTION AGENCY

[FRL-9115-5; Docket ID No. EPA-HQ-ORD-2009-0816]


A Framework for Categorizing the Relative Vulnerability of 
Threatened and Endangered Species to Climate Change

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of extension of public comment period.

-----------------------------------------------------------------------

SUMMARY: EPA is announcing an extension of the original 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). This extension is being 
granted in response to request from interested parties. 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 six U.S. threatened and endangered 
species: the golden-cheeked warbler, the salt marsh harvest mouse, the 
Mount Graham red squirrel, the Lahontan cutthroat trout, the desert 
tortoise and the bald eagle.
    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 released 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. It 
does not represent and should not be construed to represent any Agency 
policy or determination.

DATES: The original 30-day public comment period began on November 25, 
2009 and closed on December 28, 2009. All comments received to date 
will be considered, including those received after the close of the 
original public comment period. An additional 30-day comment period 
begins on February 23, 2010, and ends March 25, 2010. Comments should 
be in writing and must be received by EPA by March 25, 2010.

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 
Publications menus at http://www.epa.gov/ncea. A limited number of 
paper copies are available from the Information Management Team, NCEA;

a paper copy, please provide your name, your mailing address, and the 
document title, ``A Framework for Categorizing the Relative 
Vulnerability of Threatened and Endangered Species to Climate Change.''
    Comments may be submitted electronically via http://www.regulations.gov, by mail, by facsimile, or by hand delivery/
courier. Please follow the detailed instructions

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. 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 responses 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. 
threatened and endangered species. Based on the framework, four of 
those species were categorized as ``critically vulnerable:'' 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.
