DEPARTMENT OF THE INTERIOR
Fish and Wildlife Service
Notice of Availability of the Draft Conservation Strategy for the
Southern Rocky Mountain Population of the Boreal Toad for Review and
Comment
AGENCY: US Fish and Wildlife Service, Interior.
ACTION: Notice of document availability.
-----------------------------------------------------------------------
SUMMARY: The Fish and Wildlife Service announces the availability of a
Draft Conservation Strategy for the southern Rocky Mountain population
of the boreal toad. (Bufo boreas boreas). This population of the boreal
toad is a candidate for listing under the Endangered Species Act of
1973. The Draft Conservation Strategy compliments a State recovery plan
for this population of the boreal toad which the Colorado Division of
Wildlife had the lead for preparing. Several agencies and organizations
were involved in preparation of the recovery plan which appears as an
appendix to the Draft Conservation Strategy. The Conservation Strategy
was written by ad hoc members of the Boreal Toad Recovery Team and
included personnel with the Biological Resources Division of the US
Geological Survey, Bureau of Land Management, Colorado Division of
Wildlife, National Park Service, US Fish and Wildlife Service, and the
US Forest Service. Earlier drafts of the Conservation Strategy
underwent peer review by three scientists. One of the scientists is an
amphibian expert, Dr. Paul Bartelt, who is a professor at Waldorf
College in Iowa. Another amphibian expert, Dr. David Pettus, was a
former professor at Colorado State University. The third person, Dr.
David Cooper, is a wetland specialist at Colorado State University. The
Conservation Strategy focuses on land management practices that can be
applied to reduce or eliminate threats to the boreal toad that warrant
its candidate status. Full implementation of the Conservation Strategy
and recovery plan represents the best approach to the long-term
survival of this population of the boreal toad. The Service solicits
review and comment from the public on the Draft Conservation Strategy.
DATES: Comments on the Draft Conservation Strategy must be received on
or before June 4, 1997, to be considered for preparation of the final
Conservation Strategy.
ADDRESSES: Persons wishing to review the Draft Conservation Strategy
may obtain or request a copy from the US

SUPPLEMENTARY INFORMATION:
Background
The boreal toad (Bufo boreas boreas) is one of the two subspecies
of the western toad which is found throughout western North America.
The southern Rocky Mountain population is geographically isolated from
boreal toad populations to the north and west by dry, non-forested
intermountain valleys. It is genetically differentiated and probably
represents an independently evolving lineage or species.
The southern Rocky Mountain boreal toad occupies forest habitats
between 2250 to 3600 m (7500-12000 ft.) in Colorado, southwest Wyoming,
and north-central New Mexico. Boreal toad occupy three different types
of habitat during the course of the year: breeding ponds, summer range,
and overwinter refugia. All of these specific habitats occur within
lodgepole pine or spruce-fir forests. Few boreal toads have been
recorded from lower-elevation ponderosa pine forests and willow/sage
communities.
Southern Rocky Mountain boreal toads were once considered common to
abundant throughout the higher elevations of Colorado and southeastern
Wyoming along the Snowy and Sierra Madre ranges (Medicine Bow, Sierra
Madre and Pole Mountains). The southern periphery of the species range
was located in New Mexico along the San Juan Mountains at Lagunitas,
Canjilon, and Trout Lakes.
Boreal toad decline in New Mexico was first observed in the mid
1980's. Surveys conducted in 1989 and 1993 at the three previously
occupied boreal toad locations revealed no populations. Recent
observations of boreal toads in Colorado, within 29 km (20 miles) of
New Mexico's historically occupied areas provide some hope that boreal
toads may still exist in New Mexico. Between 1974 and 1982, 11
populations of boreal toads disappeared to the West Elk Mountains of
west-central Colorado. By the late 1980's boreal toads were absent from
85 percent of known localities in northern Colorado. Once known to
occur in 25 of 63 counties, and potentially in 7 others, the boreal
toad is absent in over 83 percent of previously known locations in
Colorado. Rangewide, primarily in Colorado, and including a single
breeding location in Wyoming, there are now 50 known breeding sites.
However, most of the sites have only a few breeding adults.
The Service received a petition to list the southern Rocky Mountain
population of the boreal toad as endangered on September 30, 1993, by
the Biodiversity Legal Foundation. The Service made a 90-day petition
finding (59 FR 37439) on July 22, 1994, that stated that sufficient
information existed to indicate that Federal listing may be warranted.
Subsequently, the Service made a 12-month finding (60 FR 15281) on
March 23, 1995, that stated that Federal listing was warranted, but
precluded by higher listing priorities.
In an effort to address the threats to the boreal toad prior to
Federal listing the Colorado Division of Wildlife assembled a Recovery
Team and published a recovery plan in 1994. The Recovery Team recently
completed a revised recovery plan in 1997 that addressed the range of
the boreal toad in Colorado as well as Wyoming and New Mexico and
provided more details for research and management recommendations. It
was also decided that a conservation strategy was needed to address
more specific land management practices. A Conservation Agreement is
also planned and signatory parties will be agreeing to follow
recommendations in the recovery plan and Conservation Strategy. The
Conservation Strategy focuses on eight general impacts to the boreal
toad and ways to reduce or eliminate those impacts.
