DEPARTMENT OF THE INTERIOR
50 CFR Part 17
Endangered and Threatened Wildlife and Plants; Reopening of
Comment Period on Data Pertaining to the Subspecies Taxonomy of the
California Gnatcatcher
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of reopening of public comment period.
-----------------------------------------------------------------------
SUMMARY: The U.S. Fish and Wildlife Service (Service) gives notice that
the comment period on the data pertaining to the subspecies taxonomy of
the California gnatcatcher is reopened through January 26, 1995. The
Service has reopened the comment period to ensure that the public may
review and comment on significant comments and analyses received during
the original public comment period, which was open from June 2, to
December 1, 1994.
DATES: Comments and materials must be received by January 26, 1995.
ADDRESSES: Comments and materials concerning the original public
comments and analyses should be submitted to the U.S. Fish and Wildlife
Service, Carlsbad Field Office, 2730 Loker Avenue West, Carlsbad,
California 92008. The data, original and subsequent public comments,
and other materials received will be available for public inspection
during normal business hours at the above address.
FOR FURTHER INFORMATION CONTACT:
Gail Kobetich, Field Supervisor, at the address listed above (telephone
619/431-9440, facsimile 619/431-9624).
SUPPLEMENTARY INFORMATION:
Background
On March 30, 1993, the U.S. Fish and Wildlife Service (Service)
published a final rule in the Federal Register determining the coastal
California gnatcatcher to be a threatened species (58 FR 16741). In its
decision to the list the gnatcatcher, the Service relied, in part, on
taxonomic studies conducted by Dr. Jonathan Atwood of the Manomet Bird
Observatory, Manomet, Massachusetts. As is the standard practice in the
scientific community, the Service did not request, nor was it offered,
the data collected and used by Dr. Atwood in reaching his conclusions.
Instead, the Service depended upon the conclusions published by Dr.
Atwood in a peer-reviewed scientific article on the subspecific
taxonomy of the California gnatcatcher (Atwood 1991).
In response to a suit filed by the Endangered Species Committee of
the Building Industry Association of Southern California and other
plaintiffs, the United States District Court of the District of
Columbia vacated the listing of the coastal California gnatcatcher
because the Service did not make available Atwood's data for public
review and comment. In response to the court decision, Dr. Atwood
released his data to the Service, which the agency made available to
the public for review and comment on June 2, 1994 (59 FR 28508). On
June 16, 1994, the court reinstated threatened status for the coastal
California gnatcatcher until the Secretary of the Interior determines
in a finding whether the listing should be revised or revoked in light
of his review of the subject data and public comments received during
the comment period. As a result of the court orders of July 27, 1994,
and September 30, 1994, the Service extended the comment period to
December 1, 1994, (59 FR 38426, 59 FR 44125, and 59 FR 53628).
The Service received 11 substantive comments in response to the
request for public comments on Dr. Atwood's data and analysis. Of
particular note, Dr. William Link mathematician, and Grey Pendleton,
biometrician, with the National Biological Survey (NBS) conducted new
analyses of these data and presented it in a report (Link and Pendleton
1994). Their four conclusions were:
(1) That the morphological characters in Atwood's data set vary
along the geographical gradient,
(2) That the changes in characters are more reasonably represented
by discrete groupings than by a gradual pattern of change, and are thus
consistent with the existence of subgroups within the population,
(3) That there is at least 1 break north of site 5 (Atwood's BG27)
[approximately 30 deg. N latitude], and
(4) That there is at least 1 break south of site 5.
Moreover, the Service received two additional statistical analyses
(Dr. Atwood; and Dr. Karen Messer, Department of Mathematics,
California State University, Fullerton) that supported a southern
terminus of 30 deg. N latitude for the coastal California gnatcatcher.
However, the Service received three significant comments that, for
various reasons, did not support such a southern terminus (Dr. George
Barrowclough, ornithologist from New York; Dr. Lyman McDonald,
consultant from Wyoming; and Dr. James MacMahon and other colleagues,
College of Science, Utah State University).
In light of the NBS report (Link and Pendleton 1994), the Service
reopens the comment period to ensure that the public may review and
comment on this and other significant comments and analyses received
during the original public comment period. The comment period is opened
through January 26, 1995.
