Endangered and Threatened Wildlife and Plants; 12-Month Finding
for a Petition to List the Dakota Skipper as Endangered or Threatened
AGENCY: U.S. Fish and Wildlife Service, Interior.
ACTION: Notice of 12-month petition finding.
-----------------------------------------------------------------------
SUMMARY: The U.S. Fish and Wildlife Service (Service) announces a 12-
month finding for a petition to list the Dakota skipper (Hesperia
dacotae Skinner) under the Endangered Species Act of 1973, as amended.
The Service finds that the petition does not present substantial
scientific or commercial information indicating that the listing may be
warranted at this time.
DATES: The finding announced in this document was made on February 16,
1995.
ADDRESSES: Comments, or questions concerning this petition should be
submitted to the Chief, Division of Endangered Species, U.S. Fish and
Wildlife Service, Bishop Henry Whipple Federal Building, 1 Federal
Drive, Fort Snelling, Minnesota 55111-4056. The petition finding,
supporting data, and comments are available for public inspection, by
appointment, during normal business hours at the above address.
FOR FURTHER INFORMATION CONTACT: Ms. Carlita Shumate, Invertebrate
Species Coordinator, Division of Endangered Species, at the above
address (612/725-3276).
SUPPLEMENTARY INFORMATION:
Background
Section 4(b)(3)(B) of the Endangered Species Act (Act) of 1973, as
amended (16 U.S.C. 1531 et seq.), requires that, for any petition to
revise the List of Endangered and Threatened Wildlife and Plants that
presents substantial scientific and commercial information, the Service
make a finding within 12 months of the date of the receipt of the
petition on whether the petitioned action is (a) not warranted, (b)
warranted, or (c) warranted but precluded from immediate proposal by
other pending proposals of higher priority. Section 4(b)(3)(C) requires
that petitions for which the requested action is found to be warranted
but precluded should be treated as though resubmitted on the date of
such finding, i.e., requiring a subsequent finding to be made within 12
months. Such 12-month findings are to be published promptly in the
Federal Register.
On January 21, 1994, The Service received a petition dated January
15, 1994, from Brendan McManus of the Biodiversity Legal Foundation, to
list the Dakota skipper (Hesperia dacotae) as endangered or threatened
and designate critical habitat. The Service made a 90-day finding that
the petition presented substantial information indicating that the
requested action may be warranted. The 90-day finding was announced in
the Federal Register on July 28, 1994 (59 FR 38424). A status review of
the species was continued.
The Dakota skipper was designated a category 2 candidate species in
the May 22, 1984, Notice of Review (49 FR 21664) and has remained in
category 2 to date (January 6, 1989, 54 FR 572; November 21, 1991, 56
FR 58830; and November 15, 1994, 59 FR 59020). A category 2 candidate
is a species for which information in the Service's possession
indicates that listing is possibly appropriate, but for which
insufficient information on biological vulnerability and threats is not
currently available to support a proposal for listing under the Act.
The Service has reviewed the petition, literature cited in the
petition, information presented by various parties in response to the
90-day finding, other available literature and information, and has
consulted with biologists and researchers familiar with the Dakota
skipper. On the basis of the best scientific and commercial information
available, the Service finds listing is not warranted at this time. The
review concludes that there is not persuasive evidence that elevation
of the species to category 1 is appropriate and, therefore, the species
will be retained in category 2.
The Dakota skipper is a small to medium-sized butterfly found in
mid- and tall grass prairie. Information on current status can be
summarized as follows. Dakota skippers are reported in Iowa, Minnesota,
North and South Dakota, and Manitoba, Canada. The species was formerly
found in Illinois. The species is currently known in 12 counties (19
population sites) in Minnesota, 17 counties (32 population sites) in
North Dakota, and seven counties (18 population sites) in South Dakota,
and in one county (one population site) in Iowa (Royer and Marrone
1992; Ronald Royer, Minot, North Dakota, State University, in litt.
1994; Robert Dana, Minnesota Department of Natural Resources, in litt.
1994). Unknown Dakota skipper populations may exist; nine of the
fifteen respondents to the 90-day notice indicated that additional
areas need to be surveyed, including areas of North Dakota, Minnesota,
and Iowa.
The Dakota skipper faces loss and degradation of its prairie
habitat due to certain harmful burning, haying, grazing and pesticide
use practices. Invasion of prairie by alien plants, natural succession,
and habitat loss through physical conversion of prairie to other
purposes are also negative factors. The Dakota skipper (and its
habitat) are in long-term decline, but the demise of the species does
not appear imminent. The Service believes additional information is
required concerning the species and its threats before making the
determination that the species is endangered or threatened within the
definition of the Act. Timely protection and appropriate prairie
management might eliminate the need to list the species.
Further details regarding the biological status of the species are
contained in the administrative finding. Interested persons may obtain
a copy of the finding by contacting the office indicated in the
ADDRESSES section of this notice. [[Page 10536]]
