Endangered and Threatened Wildlife and Plants; Draft Post-
Delisting Monitoring Plan for the Concho Water Snake
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of availability of draft post-delisting monitoring plan.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce the
availability of our Post-Delisting Monitoring Plan for the Concho water
snake (Nerodia paucimaculata). The draft post-delisting monitoring
(PDM) plan describes the methods we propose to monitor the status of
the snake and its habitat, in cooperation with the State of Texas and
other conservation partners, for a 15-year period if we remove this
species from the Federal list of endangered and threatened wildlife
under another pending action. The draft PDM plan also provides a
strategy for identifying and responding to any future population
declines or habitat alterations.
DATES: To ensure consideration, please send your written comments on
the draft PDM plan for Concho water snake by October 23, 2009.
ADDRESSES: The draft PDM plan is available for review on the Internet
at http://endangered.fws.gov and http://www.fws.gov/southwest/es/
AustinTexas/. To request a copy of the draft PDM plan, write to U.S.
Fish and Wildlife Service, Austin Ecological Services Field Office,
10711 Burnet Road, Suite 200, Austin, TX 78758; telephone 512-490-0057;
facsimile 512-490-0974. Supporting documentation we used in preparing
the draft PDM plan is available for public inspection, by appointment,
during normal business hours, at the above office. You may submit
comments by mail to the above office address.

SUPPLEMENTARY INFORMATION:
Background
The Concho water snake is a reptile endemic to central Texas. We
listed this species as threatened under the Endangered Species Act of
1973, as amended (Act; 16 U.S.C. 1531 et seq.), effective September 3,
1986, because of threats from habitat modification and destruction (51
FR 31412). On July 8, 2008, we published a proposed rule to remove the
Concho water snake from the list of threatened species (73 FR 38956).
We based the proposal on our finding that the best available scientific
and commercial data, including new information, indicate that the
Concho water snake has recovered because threats have been eliminated
or reduced to the point that the species no longer meets the definition
of threatened or endangered under the Act. We are in the
[[Page 48596]]
process of making a final determination on whether or not to delist the
Concho water snake.
For more background information on the Concho water snake, refer to
our 1986 final listing rule published in the Federal Register (51 FR
31412), our 2008 proposed delisting rule published in the Federal
Register (73 FR 38956), Werler and Dixon (2000, pp. 209-216), Campbell
(2003, pp. 1-4), Forstner et al. (2006, pp. 1-22), Whiting et al.
(2008, pp. 438-445), and the 1993 Concho Water Snake Recovery Plan
(Service 1993, available online at http://endangered.fws.gov).
Section 4(g)(1) of the Act requires us to implement a system, in
cooperation with the States, to effectively monitor the status of each
species we remove from the Federal List of Endangered and Threatened
Wildlife and Plants due to recovery. The monitoring must occur for at
least 5 years. The purpose of post-delisting monitoring (PDM) is to
verify that a species we delist due to recovery remains secure from
risk of extinction after we remove the protections of the Act.
To fulfill the PDM requirement, we drafted a monitoring plan for
the Concho water snake in cooperation with the Texas Parks and Wildlife
Department and the Colorado River Municipal Water District. Over a 15-
year period, we propose to conduct surveys to measure the presence and
abundance of snakes 2 times a year at 18 sample sites across the range
of the snake. Biological monitoring frequency will occur in three
phases, decreasing over time, resulting in 7 years of surveys over the
15-year PDM period. Evaluation of stream conditions will consist of
analysis of hydrologic data collected at eight existing stream gages
from across the snake's range. The PDM plan describes specific
monitoring triggers where certain outcomes of monitoring will result in
specific actions. For example, if snakes are not captured from at least
75 percent of sample sites in any year, sampling effort will be
intensified the following year beyond the minimum called for in the PDM
plan. The monitoring triggers (both quantitative and qualitative) are
based on the snake's distribution, presence, reproduction, and
abundance, as well as evaluation of instream flow conditions.
The draft PDM plan includes annual reporting requirements. If PDM
results in concern regarding the status of the snake or increasing
threats, possible responses may include an extended or intensified
monitoring effort, additional research (such as modeling metapopulation
dynamics or assessing the status of the fish prey base), enhancement of
riverine or shoreline habitats, or an increased effort to improve
habitat connectivity by additional translocation of snakes between
reaches. If future information collected from the PDM, or any other
reliable source, indicates an increased likelihood that the species may
become in danger of extinction, we will initiate a status review of the
Concho water snake and determine if relisting the species is warranted.
In addition to public review of the draft PDM plan, we concurrently
are requesting independent expert peer review from knowledgeable
individuals with scientific expertise that includes ecology of water
snakes and conservation biology principles. Peer review of the draft
PDM plan is in accordance with our policy published on July 1, 1994 (59
FR 34270).
Viewing Documents
Comments and materials we receive from the public and peer
reviewers, as well as supporting documentation we used in preparing the
draft PDM Plan, will be available for public inspection by appointment,
during normal business hours at the Austin Ecological Services Field
Office (see ADDRESSES). Once approved, the final PDM plan for the
Concho water snake and any future revisions to the PDM plan will be
available on our Web page (http://endangered.fws.gov) and the Austin
Ecological Services Field Office Web page (http://www.fws.gov/
southwest/es/AustinTexas/). We will announce our final decision on
whether to delist the snake with a final rule in a future Federal
Register publication, and we will also make this final decision
available on the above-referenced Web pages.
Request for Public Comments
We intend for our final PDM plan to be as accurate and as effective
as possible. Therefore, we request comments or suggestions on the
Concho water snake draft PDM plan from the public, concerned
governmental agencies, the scientific community, industry, or any other
interested party. We will take into consideration substantive comments
we receive by the comment due date (see DATES). These comments, and any
additional information we receive, may lead us to adopt a final PDM
plan that differs from this draft PDM plan. Please note that comments
merely stating support or opposition to the action under consideration
without providing supporting information, although noted, will not be
considered in making a determination.
Before including your address, phone number, e-mail address, or
other personal identifying information in your comment, you should be
aware that your entire document--including your personal identifying
information--may be made publicly available at any time. While you may
request at the top of your document that we withhold this information
from public review, we cannot guarantee that we will be able to do so.
