ABSTRACTS OF PRESENTATIONS IN ORDER PRESENTED
<br />KANIM, N. R.; WHITE, R.; WITHERS, D. (U.S. Fish and Wildlife Service, Region 1, NRK-Sacramento Field Office, Sacramento, CA;
<br />RW-Portland Field Office, Portland, OR; DW-Reno Field Office, Reno, NV)
<br />U.S. Fish and Wildlife Service, Region 1, report on conservation actions undertaken in
<br />1992, for federally listed and candidate arid-region fishes in California, Oregon, and
<br />Nevada
<br />KEYWORDS: Nevada; California; Oregon; U.S. Fish and Wildlife Service; Region 1; Recovery plans; consultations;
<br />endangered fishes
<br />ABSTRACT
<br />The Reno Field Office has prepared a draft proposal to reclassify the Pahrump poolfish (Empeuichthys latos) from
<br />endangered to threatened status and has completed draft recovery plans for the Lahontan cutthroat trout (Oncorhynchus
<br />clarki henshaxn), White River spinedace (Lepidomeda albivallis), Big Spring spinedace (Lepidomeda mollispinis), and
<br />Railroad Valley springfish (Crenichthys nevadae). The Cui-ui (Chasmistes cujus) recovery plan has been approved and
<br />is available for distribution. A draft conservation agreement to protect the Amargosa toad (Bufo nelsont) and Oasis Valley
<br />speckled dace (Rhinichthys osculus ssp.) near Beatty, Nevada has been prepared for signature by the U.S. Fish and
<br />Wildlife Service (Service), U.S. Bureau of Land Management (BLM), and Nevada Department of Wildlife. A draft
<br />wetlands restoration plan for the Ash Meadows National Wildlife Refuge was completed in October. Hearings for the
<br />Las Vegas Valley Water District's water rights applications in eastern and southern Nevada have been delayed until July
<br />1993.
<br />The Service has issued to the U.S. Bureau of Reclamation, a jeopardy biological opinion on the effects on the
<br />federally endangered Lost River (Deltistes luxatus) and shortnose suckers (Chasmistes brevirostris) of the long-term
<br />operation of the Klamath Project in Klamath County, Oregon, and Siskiyou and Modoc County, California. The
<br />Sacramento Field Office (SFO) will complete a recovery plan and propose critical habitat for these two species in early
<br />1993. A new Klamath Basin Fish and Wildlife Service Office will be opened in Klamath Falls, Oregon, as early as
<br />February 1993. The purpose of the office, which will be staffed and funded by the Service and Reclamation, will be to
<br />launch an effort to restore wetlands in the Klamath Basin for the protection of endangered species, migratory birds, and
<br />downstream anadromous fishes. Discussions of a proposed emergency listing action for four fishes endemic to the Goose
<br />Lake Basin in Lake County, Oregon, and Modoc County, California, prompted local residents to form a committee to
<br />develop a plan to recover the Goose Lake redband trout (Oncorhynchus mykiss ssp.), Goose Lake sucker (Catostomus
<br />occidentalis lacusanserinus), Goose Lake lamprey (Lampetra tridentata ssp.), and Goose Lake tui chub (Gila bicolor
<br />thalassina). Goose Lake desiccated completely in late September or early October this year. The Service and BLM are
<br />exploring options for transplanting the Cowhead Lake tui chub (Gila bicolor vaccaceps), a Federal category-1 candidate
<br />species, which is in danger of extinction as a result of the continuing drought and current land management practices.
<br />For the past three years, Modoc National Forest Service biologists have salvaged Modoc suckers from drying pools and
<br />moved them upstream as the lower portions of several creeks continue to desiccate. The California Department of Fish
<br />and Game chemically treated the mainstem of Silver King Creek in Alpine County for the second year to remove any
<br />remaining introgressed Paiute cutthroat trout (Oncorhynchus clarki seleniris). SFO will revise the Paiute cutthroat trout
<br />recovery plan this year.
<br />The Portland Field Office issued several consultations to the Vale and Burns Districts of the BLM on the effects
<br />of grazing on the Lahontan cutthroat trout this year. The Service, Nature Conservancy, and BLM continue to cooperate
<br />in funding life history, population dynamics, and habitat requirements research on the federally listed endangered Borax
<br />Lake chub (Gila boraxobius). The current population estimate is between 25,000 and 26,000 individuals. Ongoing
<br />Warner sucker (Catostomus warnerensis) research is focused on early life history and behavior, micro-habitat needs, and
<br />the effects of drought. Conservation efforts for the Summer Basin tui chub (Gila bicolor ssp). and Hutton tui chub (Gila
<br />bicolor ssp.) have been hampered by uncooperative landowners. There is some speculation that the Summer Basin tui
<br />chub now may be extinct.

<br />ABSTRACT
<br />The Marys River "Bring Back the Natives" Project is a cooperative effort, involving the Elko District Bureau of
<br />Land Management and the Humboldt National Forest, to restore the riparian/aquatic ecosystem of the Marys River
<br />drainage. This drainage, located in northeastern Nevada, is a 520 square-mile watershed which drains into the Humboldt
<br />River. Historically, the Marys River supported a thriving population of native Lahontan cutthroat trout (Oncorhynchus
