Service Initiates Status Review of 53 Species, Recommends No Status Change for 29 Species, and Uplisting 2 Species
Service Seeks Latest Scientific Information on Species Health, Population Trends

The U.S. Fish and Wildlife Service is requesting information as part of the status reviews of 53 protected species in California, Nevada, and the Klamath Basin of Oregon. A list of 31 status reviews completed between April 1, 2010 and March 16, 2011, is also included in today’s Federal Register notice.

Required by the Endangered Species Act (ESA), the purpose of the reviews is to ensure that the listing of the species as threatened or endangered is accurate and based on the best scientific and commercial data available, and to determine whether the listing status should be considered for change. To accomplish this, the Service is requesting submission of any new information produced since the original listing of each of these 53 species by Jul 25, 2011.

Under the ESA, the Service maintains a list of endangered and threatened wildlife and plants. The Act requires that the Service conduct a review of listed species at least once every 5 years and determine whether or not any species should be removed from the list (delisted), or reclassified from endangered to threatened or from threatened to endangered. Delisting a species must be supported by the best scientific and commercial data available and only considered if such data substantiates that the species is neither endangered nor threatened for one or more of the following reasons:
– The species is considered extinct.
– The species is considered to be recovered.
– The original data available when the species was listed, or the interpretation of such data, were in error. Any change in Federal classification requires a separate rule-making process distinct from the status review.

To ensure that the review is as thorough as possible, the Service is soliciting new information about these species from the public, concerned governmental agencies, Tribes, the scientific community, industry, environmental entities, and any other interested parties. The Federal Register notice indicates where comments should be sent for each species. It also lists the appropriate contact person for information on each species.

Categories of requested information include:
– Species biology, including population trends, distribution, abundance, demographics, and genetics.
– Habitat conditions, including amount, distribution, and suitability.
– Conservation measures that have been implemented that benefit the species.
– Threat status and trends; and other new information, data, or corrections, including but not limited to taxonomic or nomenclatural changes, identification of erroneous information, and improved analytical methods.

Copies of completed 5-year reviews are also available on Service’s website:

Additionally, the U.S. Fish and Wildlife Service (Service) today announced the completion of 5-year reviews for 31 species in California and Nevada.  Twenty-nine of the reviews being announced today recommend no change in status for the species reviewed, while the reviews for Delta Smelt and Ione Manzanita each recommend uplisting these species.

These 5-year reviews were undertaken as required by section 4(c)(2)(A) of the Endangered Species Act (Act). This list of completed reviews incorporates species that were noticed for review on March 22, 2006; February 14, 2007; March 5, 2008; March 25, 2009; and May 21, 2010. The 5-year review constitutes a recommendation by the Service. Any change in the listing status will require a separate rulemaking process.

More information about the species for which 5-year reviews were completed can be found online: Big-leaved crownbeard , California Orcutt grass, Coachella Valley fringe-toed lizard, coastal California gnatcatcher, Del Mar manzanita, Laguna Beach liveforever, Otay mesa mint, Pacific pocket mouse, Santa Ana sucker, San Diego ambrosia, San Diego button celery, San Diego mesa mint, slender-horned spineflower, and slender-petaled mustard (thelypodium) [Carlsbad Fish and Wildlife Office]; desert tortoise (Mojave population) [Nevada Fish and Wildlife Office]; fountain thistle, Ione buckwheat, Ione Manzanita, Presidio clarkia, San Joaquin woolly-threads, San Mateo thornmint, Sonoma spineflower, Tiburon jewelflower, and white-rayed pentachaeta [Sacramento Fish and Wildlife Office]; Delta smelt [San Francisco Bay Delta Fish and Wildlife Office]; island malacothrix, island rush-rose, La Graciosa thistle, Lompoc yerba santa, Santa Cruz Island malacothrix, and Ventura marsh milk-vetch [Ventura Fish and Wildlife Office].

Simply enter the species name and state into the webpage.

Under the Act, the Service maintains a list of endangered and threatened wildlife and plant species at 50 CFR 17.11 (for animals) and 17.12 (for plants). The Act also requires that we conduct a review of listed species at least once every 5 years and on the basis of such reviews determine whether or not any species should be removed from the List (delisted), or reclassified from endangered to threatened (downlisted) or from threatened to endangered (uplisted). Any change in federal classification requires a separate rulemaking process distinct from the 5-year review.
