The U.S. Fish and Wildlife Service is requesting information as part of the status reviews of 58 protected species in California, Nevada, Arizona, and Utah. A list of 42 status reviews completed in mid to late 2008 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 58 species by May 26, 2009.

Since 2005 the Service has initiated status reviews of 262 listed species in California and Nevada. To date, 110 reviews have been completed.

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 taxonomic or nomenclatural changes, identification of erroneous information, and improved analytical methods.
