This book was released on 2014 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Oregon spotted frog (Rana pretiosa) occupies only a fraction of its original range and is listed as Threatened under the Endangered Species Act. We surveyed 93 sites in a rotating frame design (2010-13) in the Klamath and Deschutes Basins, Oregon, which encompass most of the species' core extant range. Oregon spotted frogs are declining in abundance and probability of site occupancy. We did not find an association between the probability that Oregon spotted frogs disappear from a site (local extinction) and any of the variables hypothesized to affect Oregon spotted frog occupancy. This 4-year study provides baseline data, but the 4-year period was too short to draw firm conclusions. Further study is essential to understand how habitat changes and management practices relate to the status and trends of this species.

This book was released on 2005 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: We evaluated the effects of herbage removal from livestock grazing on Oregon spotted frog (Rana pretiosa) habitat use by monitoring frog locations in grazed and matched ungrazed treatments across a range of grazing intensities at Jack Creek, Fremont-Winema National Forest, Oregon. Thirteen cattle exclosures were deployed along Jack Creek in the summer of 2003. Movements were monitored using radio telemetry on adult frogs (N = 24 frogs) within treatments sites from July through October 2004. Individual frogs were located 1 to 28 times ([mean]=11.7) and were tracked from 1 to 74 days [mean]=35.8 days). A 10-pinpoint intercept frame was used to estimate relative differences in removed vegetation cover. This difference between ungrazed treatments and paired grazed controls was used as a measure of grazing pressure at treatment sites, and examined in relation to frog habitat preference. Pin measurements ranged from an average monthly difference of -1.2 to 2.97 pin hits between an exclosure and its control. As pin differences increased by one unit, the odds of finding a frog in the exclosure increased by a factor of 1.62 (F1, 4 = 3.90, p = 0.05) with an approximate 95% confidence interval of 1.00 to 2.74. Based on the proportion of time frogs spent inside exclosures, there was evidence that as grazing pressure increased, frogs preferred ungrazed livestock exclosures. Secondary objectives of this study were to describe migration routes and identify overwintering sites of the R. pretiosa population on Jack Creek. From August to mid-December 2003, frogs (N = 36) were tracked from 5 to 92 days ([mean] = 49.5 days) and located 2 to 39 times ([mean] = 23.2 times). In mid-October, individuals were located in sheltered areas along the creek such as willow root complexes and abandoned beaver runs. Frogs also were found in deep (130 cm) pools associated with active springs and individuals in these areas were active within the pools under 5 cm of ice. Using mark-recapture techniques and deployment of cattle exclosures, we examined 1) frog migration and 2) grazing effects on frog habitat use for the Jack Creek R. pretiosa population in 2003-2004. Ultimately, a more complete understanding of the natural history of this species and how anthropogenic activities affect amphibians such as R. pretiosa will aid managers in mitigating potential adverse affects, especially in riparian systems, and contribute to recovery and restoration strategies.

Book excerpt: Endangered and Threatened Species - Designation of Critical Habitat for the Oregon Spotted Frog (US Fish and Wildlife Service Regulation) (FWS) (2018 Edition) The Law Library presents the complete text of the Endangered and Threatened Species - Designation of Critical Habitat for the Oregon Spotted Frog (US Fish and Wildlife Service Regulation) (FWS) (2018 Edition). Updated as of May 29, 2018 We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for the Oregon spotted frog (Rana pretiosa) under the Endangered Species Act. In total, approximately 65,038 acres (26,320 hectares) and 20.3 river miles (32.7 river kilometers) in Whatcom, Skagit, Thurston, Skamania, and Klickitat Counties in Washington, and Wasco, Deschutes, Klamath, Lane, and Jackson Counties in Oregon, fall within the boundaries of the critical habitat designation. The effect of this regulation is to designate critical habitat for the Oregon spotted frog under the Endangered Species Act.
