 Critical Habitat Proposal for Riverside Fairy Shrimp Reopened for Public Comment

Carlsbad, CA -- The U.S. Fish and Wildlife Service today announced today it is soliciting comments and information on a draft economic analysis for the June 1, 2011, proposed revision of critical habitat for the endangered Riverside fairy shrimp (Streptocephalus woottoni).

The draft economic analysis identifies potential impacts associated with the Service’s proposed designation of 2,984 acres of critical habitat in portions of Ventura, Orange, Riverside, and San Diego counties, California.

Costs specifically attributable to the designation of critical habitat for the Riverside fairy shrimp are estimated to range from $1.75 to $2.87 million over the next 24 years (assuming a 7 percent discount rate). Most these impacts are related to costs incurred from time delays to implement development projects.

An advance copy of the notice is on view today at the Federal Register Public Inspection. It officially publishes on March 1, 2012, at which time you can submit comments and information about the proposed rule and the economic analysis through the Federal eRulemaking Portal at  In the search box enter Docket No. FWS–R8–ES–2011–0013.

You may also submit comments and information by mail to:  Public Comments Processing, Attn: FWS–R8–ES–2011–0013; Division of Policy and Directives Management; U.S. Fish and Wildlife Service; 4401 N. Fairfax Drive, MS 2042–PDM; Arlington, VA 22203.

The Service will accept public comments until April 2, 2012.

A new revised final designation must be submitted to the Federal Register by November 15, 2012.
Riverside fairy shrimp measure less than an inch long and are found in vernal pools, ponds, and other ephemeral pool-like bodies of water. During dry periods, cysts of the species lay dormant in the soil and hatch when adequate rainfall fills the ponds and pools.

The ESA provides a critical safety net for America’s native fish, wildlife and plants. This landmark conservation law has prevented the extinction of hundreds of imperiled species across the nation and promoted the recovery of many others.

The Service’s priority is to make implementation of the ESA less complex, less contentious and more effective.  The agency seeks to accelerate recovery of threatened and endangered species across the nation, while making it easier for people to coexist with these species.
