2013 Draft Mazama Pocket Gopher Status Update and Recovery Plan
DRAFT Mazama Pocket Gopher Status Update and Recovery Plan Derek W. Stinson Washington Department of Fish and Wildlife Wildlife Program 600 Capitol Way N Olympia, Washington January 2013 In 1990, the Washington Wildlife Commission adopted procedures for listing and de-listing species as endangered, threatened, or sensitive and for writing recovery and management plans for listed species (WAC 232-12-297, Appendix A). The procedures, developed by a group of citizens, interest groups, and state and federal agencies, require preparation of recovery plans for species listed as threatened or endangered. Recovery, as defined by the U.S. Fish and Wildlife Service, is the process by which the decline of an endangered or threatened species is arrested or reversed, and threats to its survival are neutralized, so that its long-term survival in nature can be ensured. This is the Draft Washington State Status Update and Recovery Plan for the Mazama Pocket Gopher. It summarizes what is known of the historical and current distribution and abundance of the Mazama pocket gopher in Washington and describes factors affecting known populations and its habitat. It prescribes strategies to recover the species, such as protecting populations and existing habitat, evaluating and restoring habitat, and initiating research and cooperative programs. Target population objectives and other criteria for down-listing to state Sensitive are identified. As part of the State’s listing and recovery procedures, the draft recovery plan is available for a 90-day public comment period.

Survey of the Current Distribution of the Southeastern Pocket Gopher ( Geomys Pinetis ) in Georgia
SURVEY OF THE CURRENT DISTRIBUTION OF THE SOUTHEASTERN POCKET GOPHER ( GEOMYS PINETIS ) IN GEORGIA Final Report to Georgia Department of Natural Resources Southern Wildlife Consults June 20, 2008 EXECUTIVE SUMMARY The southeastern pocket gopher ( Geomys pinetis ) is listed as a high priority species for conservation in Georgia. Reports from the early 1980s suggested that the species’ distribution had been significantly reduced from its historic distribution in the state. Because the species was locally abundant in suitable habitats, but absent from large parts of historical range, habitat loss was considered a primary factor driving the distribution reduction. However, little information is available on current distribution and availability of suitable habitat. The overall goal of this project was to assess the current distribution and habitat associations of the southeastern pocket gopher in Georgia. Specific goals were to determine the current occupancy status of historic southeastern pocket gopher localities known from museum and publication records, to develop habitat models of pocket gopher presence or absence based habitat characteristics at occupied and random locations, and to apply the predictive model across the potential distribution in Georgia to identify additional areas where suitable habitat conditions exist. We obtained a compiled a list of 297 historic southeastern pocket gopher locations in Georgia from Paul Skelley at the Florida State Collection of Arthropods. We surveyed 272 (97% of useable locations) of the historical pocket gopher localities in 41 counties during a roadside survey from June-August 2006. We documented current pocket gopher activity at 65 (24%) of the historic locations in 18 counties. Using a kernel density estimator in the GIS, we identified 5 high pocket gopher density areas. -
Ecological Relevance of Subterranean Herbivorous Rodents in Semiarid Coastal Chile
Revista Chilena de Historia Natural 66: 357-368, 1993 Ecological relevance of subterranean herbivorous rodents in semiarid coastal Chile Importancia ecol6gica de roedores herbfvoros subterráneos en el desierto costero de Chile LUIS C. CONTRERAS1, JULIO R. GUTIERREZ1, VICTOR VALVERDE1 and GEORGE W. COX2 1 Departamento de Biologfa, Universidad de La Serena, Casilla 599, La Serena, Chile. 2 Biology Depanment, San Diego State University, San Diego, CA 91182-0057, USA. ABSTRACT We first call attention to the ecological relevance and characteristics of subterranean herbivorous rodent activities in different ecosystems. Second, we note that in arid coastal Chile the ecological impact of their activities is considerable, showing similarities, as well as important differences, to impacts in other areas of the world. The amount of excavated soil deposited on the surface is similar to that reported for pocket gophers in North America. These rodents also promote dominance of introduced mediterranean annual plants. In Chile, as in South Africa, however, they seem to greatly promote the growth of geophytes, which are their preferred food. Their activities promote large-scale soil homogeneity. We hypothesize that these aspects of their ecology in Chile reflect a close relationship between a fluctuating and unpredictable climate, a relatively constant availability of clumped geophytes, and the colonial social system of these rodents, all of which promote a slow but constant shifting of their foraging areas. Subterranean rodents certainly play an important role in determining the structure and dynamics of plants in the coastal arid ecosystem in Chile. However, very little is known about the mechanisms involved. Key words: Chile, desert ecology, soil disturbance, Spalacopus, subterranean rodents, geophytes. -
