DEPARTMENT OF THE INTERIOR
50 CFR Part 17
Endangered and Threatened Wildlife and Plants; 90-Day and 12-
Month Findings for a Petition To List 83 Mollusc Species
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of petition findings.
-----------------------------------------------------------------------
SUMMARY: The U.S. Fish and Wildlife Service (Service) announces 90-day
and 12-month findings on a petition to list 83 mollusc species under
the Endangered Species Act of 1973, as amended (Act). After careful
assessment of the best scientific and commercial information available
regarding the present and future threats facing the petitioned species,
the Service either finds that the petition did not present substantial
information indicating that the requested action may be warranted (90-
day finding) or determines that the petitioned action is not warranted
at this time (12-month finding).
DATES: The finding announced in this document was made on June 28,
1994. Comments and materials related to this petition finding may be
submitted until further notice to the Assistant Regional Director for
Ecological Services at the address listed below.
ADDRESSES: Data, information, comments, or questions concerning the
status of the petitioned species described below should be submitted to
the Assistant Regional Director for Ecological Services, U.S. Fish and
Wildlife Service, Regional Office, 911 N.E. 11th Avenue, Portland,
Oregon 97232-4181. The petition, findings, supporting data, and
comments are available for public inspection, by appointment, during
normal business hours at the above address.
FOR FURTHER INFORMATION CONTACT: Jim Bartel, Chief, Division of Listing
and Recovery, at the address above or 503/231-6131.
SUPPLEMENTARY INFORMATION:
Background
Section 4 of the Endangered Species Act of 1973, as amended (16
U.S.C. 1533) (Act), requires that the Service make a finding on whether
a petition to list, delist, or reclassify a species presents
substantial scientific or commercial information indicating that the
petitioned action may be warranted. The 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 receipt of the petition, and the finding is to be published
promptly in the Federal Register. If the Service finds that a petition
presents substantial information indicating the requested action may be
warranted, then the Service initiates a status review on that species.
Section 4 (b)(3)(b) of the Act requires that for any petition that
presents substantial scientific and commercial information, a finding
be made within 12 months of the date of 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 to list, delist, or reclassify species. Such 12-month
findings are to be published promptly in the Federal Register.
The Service has made a negative 90-day finding for 75 noncandidate
species referenced in a petition to list 83 mollusc species as
threatened or endangered. The Service has made a positive 90-day
finding, but not warranted 12-month finding for the eight category 2
candidate species contained in the petition to list 83 mollusc species
as threatened or endangered. The Service has been assessing the status
of these eight species since their designation as category 2
candidates. Minimal new information was received or available to the
Service beyond that used to assign these species to category 2. As a
result, the Service determines that the petitioned action is not
warranted at this time. These eight species will be retained in
category 2. This notice also serves to announce a negative 90-day
finding on a previous petition to list the giant Columbia River limpet
(short-faced lanx) (Fisherola nuttalli) as threatened or endangered.
On August 18, 1993, the Service received a petition from the Oregon
Natural Resources Council (ONRC) to list 83 mollusc species as
threatened or endangered. The petition was dated August 16, 1993. The
document used to support the petition was the report ``Mollusc Species
of Special Concern within the Range of the Northern Spotted Owl''
(Frest and Johannes 1993) prepared for the President's Proposed Forest
Plan. On November 6, 1987 the Service received a petition from Dr.
Peter Bowler of Laguna Beach, California, to list the giant Columbia
River limpet as endangered. The giant Columbia River limpet, or short-
faced lanx, was one of the species included in the ONRC petition and
was evaluated along with the other petitioned species.
The petition involves 36 land snails, 7 slugs, 37 freshwater
snails, and 3 freshwater clams. The species are found primarily in the
states of Washington, Oregon, California, and Idaho. Most of these
species are associated with late-successional forests or riparian
areas.
The Service's finding is based on information in the petition,
references in the petition, Service files, and consultations with
malacologists, Service, and other Federal and State personnel. All
documents are on file in the Service's Regional Office in Portland,
Oregon.
Adequate rangewide surveys have not been completed for any of the
species, except for the Trinity bristlesnail (Monadenia setosa) (a
category 2 candidate). The Service also lacks evidence of specific
threats throughout the ranges of any of the petitioned taxa, especially
any threat associated with a population decline. Many of the species
covered by this petition may be sensitive to ecological perturbations
resulting from the impacts of human activities. However, information
was not presented to show correlations between the species' ecological
sensitivity and any declines in population numbers. The taxonomic
distinctiveness or validity of many of the species has not been
determined.
The Service encourages all interested parties to investigate the
population status of and threats to all the species considered in this
petition. The Service also encourages all interested parties to submit
information that may provide additional specific information on the
status of these species or specific threats to their survival.
The petition has been reviewed by staff at the Regional Office in
Portland, Oregon. The Service finds that the listing of the eight
category 2 candidates (Dalles sideband (Monadenia fidelis minor), rocky
coast sideband (Monadenia fidelis pronotis), Trinity bristlesnail,
Shasta sideband (Monadenia troglodytes), Karok hesperian (Vespericola
karokorum), Columbia pebblesnail (Fluminicola columbiana), California
floater (Anodonta californiensis), montane peaclam (Pisidium
ultramontanum) is not warranted at this time. The Service finds that
the petitioner has not presented substantial information indicating
that listing of the remaining 75 species may be warranted (Hooded

otherwise available to the Service at this time. If information becomes
available indicating that listing as endangered or threatened is
appropriate, the Service would propose to list any such mollusc.
