DEPARTMENT OF THE INTERIOR
50 CFR Part 17
Endangered and Threatened Wildlife and Plants; 90-Day Finding for
a Petition To List the Grass Lake/Green Cove Creek Population of the
Olympic Mudminnow as Endangered and To Designate Critical Habitat
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of 90-day petition finding.
-----------------------------------------------------------------------
SUMMARY: The Fish and Wildlife Service (Service) announces a 90-day
finding for a petition to list the Grass Lake/Green Cover Creek
population of the Olympic mudminnow (Novumbra hubbsi) under the
Endangered Species Act of 1973, as amended. The Service finds that the
petition did not present substantial scientific or commercial
information indicating that listing this population may be warranted.
The Service concludes that the Olympic mudminnows occupying the Grass
Lake/Green Cove Creek drainage do not constitute a distinct population
segment.
DATES: The finding announced in this document was made on May 23, 1995.
ADDRESSES: Data, information comments, or questions concerning this
petition should be submitted to the State Supervisor, U.S. Fish and
Wildlife Service, Ecological Services Office, 3704 Griffin Lane SE.,
Suite 102, Olympia, Washington 98501-2192. 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:
David C. Frederick, Field Office Supervisor, see ADDRESSES section
above or telephone 206-753-9440.
SUPPLEMENTARY INFORMATION:
Background
Section 4(b)(3)(A) of the Endangered Species Act (Act) of 1973, as
amended (16 U.S.C. 1531 et seq.), requires that the Service make a
finding on whether a petition to list, delist, or reclassify a species
presents substantial scientific or commercial information to
demonstrate that the petitioned action may be waranted. This finding is
to be based on all information available to the Service at the time the
finding is made. To the maximum extent practicable, this finding is to
be made within 90 days of the date the petition was received, and the
finding is to be published promptly in the Federal Register. If the
finding is that substantial information was presented, the Service also
is required to commence a review of the status of the species involved
if one has not already been initiated under the Service's internal
candidate assessment process.
The Service has made a finding on a petition to list the Grass
Lake/Green Cover Creek population of the Olympic mudminnow (Novumbra
hubbsi). The petition, dated September 15, 1994, was submitted by
Theodore A. Mahr, attorney representing the ``Save Allison Springs''
Citizens Committee, and several members of the ``Save Allison Springs''
Citizens Committee. The ``Save Allison Springs'' Citizens Committee is
located in Olympia, Washington. The petition requests the Service to
list the Grass Lake/Green Cove Creek population of the Olympic
mudminnow as an endangered species and to simultaneously designate
critical habitat for the population. The petitioner stated that the
Olympic mudminnow in the Grass Lake/Green Cover Creek Basin may be an
evolutionarily significant unit due to the apparent geographic
isolation of this population; that this population may be imperiled by
present and proposed housing developments in the Green Cove Creek
Basin; and that existing regulatory mechanisms may not be adequate to
protect this population.
The Service has reviewed the petition, the literature cited in the
petition, and other information available in the Service's files. On
the basis of the best scientific and commercial information available,
the Service finds the petition does not present substantial information
that listing this population may be warranted.
The Olympic mudminnow, a small, brightly colored fish in the
Umbridae family, represents a monotypic genus, being the only species
in the genus Novumbra. There are four genera in the family Umbridae,
three found in North America, the fourth in Europe. Distribution of the
Olympic mudminnow is limited to southwestern Washington and the Olympic
Peninsula. Meldrim (1968) suggests that geological history has
determined the general distribution of the species, while behavior and
habitat preference have maintained the present limited distribution.
Dispersal is limited yet the species is often abundant where found
(Wydoski and Whitney 1979). This freshwater species is generally found
in quiet, slow moving waters such as in swamps, bogs, ponds, ditches,
shallow lagoons and most frequently in marshy habitats. The preferred
habitat type is a marshy stream with a muddy bottom, dense vegetation,
and stained or dark water (Harris 1974).
A species that is in danger of extinction throughout all or a
significant [[Page 30829]] portion of its range may be listed as an
endangered species under the Act. The term ``species'' is defined in 16
U.S.C. 1532 (16) as including ``any subspecies * * * and any distinct
population segment of any species of vertebrate fish or wildlife which
interbreeds when mature.'' Thus the first deliberation is whether the
Olympic mudminnow in the Grass Lake/Green Cove Creek Basin is a
recognized subspecies or distinct population that interbreeds.
The Service has considered two factors in determining whether this
population would be eligible for listing as a distinct population
segment:
1. The discreteness of the population segment in relation to the
remainder of the species, and
2. The significance of the population segment to the species.
While the petitioner cited a 1994 letter from Dr. Theodore W.
Pietsch (College of Ocean and Fishery Sciences, University of
Washington) as evidence of the discreteness and significance of the
Grass Lake/Green Cove Creek population, Pietsch only speculated in his
letter about the ``apparently long-term geological and genetic
isolation'' of this population. He also noted that the reality of
whether this population represents ``an `evolutionary significant unit'
* * * should be explored further using modern genetic techniques.'' In
this regard, the petitioner does not present, nor is the Service aware
of any information indicating the genetic, morphological, or behavioral
distinctness of the Olympic mudminnow from the Grass Lake/Green Cove
Creek Basin.
Further, Congress directed that the listing of populations be used
`` * * * sparingly.'' Therefore, in addition to meeting the criteria
for distinctness, the Service should consider a population's biological
and ecological significance to the species as a whole. No evidence was
presented to suggest that the loss of the mudminnows in Green Cove
Creek would result in a significant gap in the range of the Olympic
mudminnow, nor that this population occurs in an unusual or unique
setting.
The Service concludes that the data contained in the petition,
referenced in the petition, and otherwise available to the Service does
not present substantial information that the requested action may be
warranted since the Grass Lake/Green Cove Creek Basin population of
Olympic mudminnows would not be eligible for listing as a distinct
population. The Olympic mudminnow is recognized as a category 2
candidate species (59 FR 58999, November 15, 1994), and has been since
the Service's December 30, 1982, Notice of Review (47 FR 58454). The
Olympic mudminnow has been the subject of an ongoing status review
since the 1982 Notice of Review. The Service will retain this species
as a category 2 candidate, and will continue to seek information
regarding the status or threats to the species. If additional data
become available in the future, the Service may reassess the listing
priority for this species or the need for listing.
