Service Announces Realignment of Three Ecological Services Offices

SACRAMENTO, CA -- U.S. Fish and Wildlife Service’s Pacific Southwest Region is realigning the area of responsibility for three of its Ecological Services offices - Palm Springs, Ventura, and Reno, effective June 2014.

“Adjusting the boundaries of these offices will benefit local communities, Tribes and other government agencies and will better align our offices working on high-profile species conservation issues, including bi-state sage grouse and desert tortoise,” said Ren Lohoefener, Regional Director.

The Palm Springs Fish and Wildlife Office will now include all of Imperial, Riverside, and San Bernardino counties, and the desert portions of Inyo, Los Angeles, and Kern counties. The Nevada Fish and Wildlife Office will expand its area of responsibility to portions of Inyo and Mono counties, including Inyo National Forest and the Owens Valley. The Ventura Fish and Wildlife Office will focus on conservation issues from Santa Cruz County south to western Los Angeles County.

If you have questions about these boundary adjustments, please contact one of the following Fish and Wildlife Service representatives:

Palm Springs Office: Ken Corey, Assistant Field Supervisor, (760) 322-2070
Nevada Office: Ted Koch, State Supervisor, (775) 861-6311
Ventura Office: Steve Henry, Field Supervisor, (805) 644-1766

Ecological Services

Ecological Services staff use the best available science and sound managerial techniques to further the Service's mission to conserve, protect, and enhance fish and wildlife and their habitats for the continuing benefit of the American people. In doing this, staff integrate their Federal authorities with social, political, and economic realities to ensure sound resource decisions while recognizing the importance of a partnership approach addressing the needs of stakeholders, since the vast majority of fish and wildlife habitat is in private ownership. In addition, education and information dissemination are integral parts of all of our activities.

Program Overview

As the principal federal partner responsible for administering the Endangered Species Act (ESA), we take the lead in recovering and conserving our Nation's imperiled species by fostering partnerships, employing scientific excellence, and developing a workforce of conservation leaders. As we work in partnership with others, our two major goals are to: 1) Protect endangered and threatened species, and then pursue their recovery; and 2) Conserve candidate species and species-at-risk so that listing under the ESA is not necessary. These goals are achieved through the following activities:

Listing and Critical Habitat

Through the Listing Program, the Service determines whether to add a species to the Federal list of endangered and threatened wildlife and plants. Listing affords a species the full range of protections available under the ESA, including prohibitions on killing, harming or otherwise "taking" a species. In some instances, listing can be avoided by the development of Candidate Conservation Agreements which may remove threats facing the candidate species.


The goal of the Endangered Species Act is the recovery of listed species to levels where protection under the Act is no longer necessary. Towards that goal, we develop and implement recovery plans that provide detailed site-specific management actions for private, Federal, and State cooperation in conserving listed species and their ecosystems.

5-Year Reviews

The U.S. Fish and Wildlife Service reviews the status of each federally listed species under the Endangered Species Act of 1973 every five years. We conduct these reviews to ensure that our classification of each species on the lists of Endangered and Threatened Wildlife and Plants as threatened or endangered is accurate. A 5-year review assesses the best scientific and commercial data available at the time of the review. Based on review results, we determine whether we should change the listing status of any of these species. You will find notices of Pacific Southwest Region reviews here.

Candidate Conservation

Working in partnership with public and private landowners, the Candidate Conservation Program assesses species and develops and facilitates the use of voluntary conservation tools for collaborative conservation of candidate and other species-at-risk and their habitats, so that these species do not need the protection of the Endangered Species Act.


The ESA directs all Federal agencies to use their existing authorities to conserve threatened and endangered species and, in consultation with the Service, to ensure that their actions do not jeopardize listed species or destroy or adversely modify critical habitat. This applies to management of Federal lands as well as other Federal actions that may affect listed species, such as Federal approval of private activities through the issuance of Federal permits, licenses, or other actions.


Grants for states and territories, offered through the Cooperative Endangered Species Conservation Fund, fund participation in a wide array of voluntary conservation projects for candidate, proposed and listed species. These funds may in turn be awarded to private landowners and groups for conservation projects.

Habitat Conservation Plans

To obtain a permit for conducting activities that might incidentally harm endangered or threatened wildlife, private landowners, corporations, State or local governments, Tribes or other non-Federal landowners need to develop a Habitat Conservation Plan (HCP), designed to offset any harmful effects the proposed activity might have on the species. The Service assists applicants throughout the HCP process, allowing development to proceed consistent with conserving listed species.

International Activities

While the Endangered Species Program deals primarily with species found in the U.S. and our territories, and the International Affairs Program deals primarily with foreign endangered species, these species occasionally overlap. Both programs work closely with the governments of Canada and Mexico to cooperatively conserve species at risk across North America.

Working With Tribes

Actions taken under authority of the ESA may affect Indian lands, tribal trust resources, or the exercise of American Indian tribal rights. Accordingly, the Service carries out its responsibilities in a manner that harmonizes the Federal trust responsibility to tribes, tribal sovereignty, and our mission, and strives to ensure that Indian tribes do not bear a disproportionate burden for the conservation of listed species, so as to avoid or minimize the potential for conflict and confrontation.
