Fish and Wildlife Service, and California Department of Fish and Game. Drawing on genetic data from six generations of Pacific pocket mice in this program, a new study has tracked reproductive success relative to a mouse's ancestral population. Partners include Transportation Corridor Agencies, U.S. Tasks included:ġ) Studying dispersal characteristics and other pertinent biological information on the speciesĢ) Performing detailed field studies of a surrogate subspecies to perfect field methods and design monitoring programsģ) Determining the feasibility of a translocation or reintroduction program for the species, determining baseline measures of genetic diversity within and between extant (using live-captured specimens) and historic (using museum specimens) populations and developing genetic goals for the recovery programĤ) Coordinating ongoing monitoring studies at extant population sites to maximize the value of the monitoring data for both scientific and preserve management goals
The project area will be systematically surveyed on foot to determine the presence and map the distribution of any suitable habitat for the Los Angeles pocket mouse within the project boundaries.
The Pacific pocket mouse ( Perognathus longimembris pacificus ) is one of 19 recognized subspecies of the little pocket mouse ( P.
CBI staff discovered one of the populations and led comprehensive efforts to identify all potential habitat areas and inform efforts to recover the species from the brink of extinction. pan1us), and/or Pacific pocket mouse (Perognathus mbris paci.ficus). The Pacific pocket mouse is among the smallest subspecies of little pocket mice, ranging up to 5.2 in (13.2 cm) in length from nose to tip of tail. The critically endangered Pacific pocket mouse ( Perognathus longimembris pacificus), once thought extinct was rediscovered at 4 sites along the coast of southern California during the 1990s. The Pacific Pocket Mouse (Perognathus longimembris pacificus) is a species of concern belonging in the species group 'mammals' and found in the following area(s): California.
