This document is scheduled to be published in the Federal Register on 04/25/2013 and available online at http://federalregister.gov/a/2013-09598, and on FDsys.gov Billing Code 4310–55 DEPARTMENT OF THE INTERIOR Fish and Wildlife Service 50 CFR Part 17 [Docket No. FWS–R8–ES–2012–0074] [4500030113] RIN 1018–AY07 Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for the Sierra Nevada Yellow-legged Frog, the Northern Distinct Population Segment of the Mountain Yellow-legged Frog, and the Yosemite Toad AGENCY: Fish and Wildlife Service, Interior. ACTION: Proposed rule. SUMMARY: We, the U.S. Fish and Wildlife Service, propose to designate critical 1 habitat for the Sierra Nevada yellow-legged frog, the northern distinct population segment (DPS) (populations that occur north of the Tehachapi Mountains) of the mountain yellow-legged frog, and the Yosemite toad under the Endangered Species Act of 1973, as amended (Act). In total, we propose to designate as critical habitat approximately 447,341 hectares (1,105,400 acres) for the Sierra Nevada yellow-legged frog in Butte, Plumas, Lassen, Sierra, Nevada, Placer, El Dorado, Amador, Calaveras, Alpine, Mariposa, Mono, Madera, Tuolumne, Fresno, and Inyo Counties, California; approximately 89,637 hectares (221,498 acres) for the northern DPS of the mountain yellow-legged frog in Fresno and Tulare Counties, California; and approximately 303,889 hectares (750,926 acres) for the Yosemite toad in Alpine, Tuolumne, Mono, Mariposa, Madera, Fresno, and Inyo Counties, California. DATES: We will accept comments received or postmarked on or before [INSERT DATE 60 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]. -
Species Status Assessment Report for the Eastern Population of The
Species Status Assessment Report for the Eastern Population of the Boreal Toad, Anaxyrus boreas boreas Prepared by the Western Colorado Ecological Services Field Office U.S. Fish and Wildlife Service, Grand Junction, Colorado EXECUTIVE SUMMARY This species status assessment (SSA) reports the results of the comprehensive biological status review by the U.S. Fish and Wildlife Service (Service) for the Eastern Population of the boreal toad (Anaxyrus boreas boreas) and provides a thorough account of the species’ overall viability and, therefore, extinction risk. The boreal toad is a subspecies of the western toad (Anaxyrus boreas, formerly Bufo boreas). The Eastern Population of the boreal toad occurs in southeastern Idaho, Wyoming, Colorado, northern New Mexico, and most of Utah. This SSA Report is intended to provide the best available biological information to inform a 12-month finding and decision on whether or not the Eastern Population of boreal toad is warranted for listing under the Endangered Species Act (Act), and if so, whether and where to propose designating critical habitat. To evaluate the biological status of the boreal toad both currently and into the future, we assessed a range of conditions to allow us to consider the species’ resiliency, redundancy, and representation (together, the 3Rs). The boreal toad needs multiple resilient populations widely distributed across its range to maintain its persistence into the future and to avoid extinction. A number of factors influence whether boreal toad populations are considered resilient to stochastic events. These factors include (1) sufficient population size (abundance), (2) recruitment of toads into the population, as evidenced by the presence of all life stages at some point during the year, and (3) connectivity between breeding populations. -

(Anaxyrus (Formerly Bufo) Canorus) in the Sierra National Forest, California
Journal of Herpetology, Vol. 47, No. 4, 555–564, 2013 Copyright 2013 Society for the Study of Amphibians and Reptiles Movements and Habitat Use of Yosemite Toads (Anaxyrus (formerly Bufo) canorus) in the Sierra National Forest, California CHRISTINA T. LIANG USDA Forest Service, Pacific Southwest Research Station, Davis, California 95618 USA; E-mail: [email protected] ABSTRACT.—The Yosemite Toad (Anaxyrus (formerly Bufo) canorus) is a high-elevation species endemic to the central Sierra Nevada mountain range in California whose populations are in decline. There is limited information on their terrestrial movement and habitat use, which impairs our understanding of the ecology and habitat needs of this sensitive species. I present radio-tracking data collected from 35 adult toads in the Sierra National Forest during daylight hours in the late spring and summer of 2007–2009. Movements, microsite cover type, and terrestrial habitat are analyzed and interpreted with regard to life-history characteristics of A. canorus. Adult toads moved a mean distance of 270 m from aquatic breeding sites, and the maximum distance recorded was 1.26 km. Females moved significantly longer distances than did males and had a larger home range. Distance traveled was related to ordinal day as well as the interaction between day and sex. Adult A. canorus used terrestrial environments extensively and were found in the mixed-conifer forest in dry habitat. Burrows were the most commonly used cover type, but other protective cover such as logs, rocks, and tree stumps were also used. The locations occupied by adult toads in the terrestrial environment were structurally different than other surrounding areas; occupied sites had less canopy cover and fewer woody species than did unoccupied sites. -

Saving the Yosemite Toad
EXPERT INSIGHTS SAVING THE YOSEMITE TOAD HEALTHY ECOSYSTEMS DEPEND ON HEALTHY TOADS BY HEATHER McKENNY, AQUATIC ECOLOGIST itting quietly in the warm, springtime sun in one of Yosemite’s ABOVE A female Yosemite toad in its natural high- picturesque meadows, you may be fortunate enough to experience elevation aquatic habitat. the rare joy of hearing the Yosemite toad’s musical call. Visitors have described the toad’s call as a strikingly clear, high-pitched trill with its mellow notes being a “pleasing additionS to the chorus of bird songs just after the snow leaves”. In fact, the toad’s scientific name “canorus” means “tuneful” in Latin, referring to the male’s melodious call to attract mates during the early-spring breeding season. Hearing the Yosemite toad’s chorus was once a common pleasure for spring visitors to the High Sierra. Sadly, Yosemite’s meadows are much quieter today due to substantial population declines. Scientists estimate that we have lost between 47 percent and 79 percent of our Yosemite toad populations, and that the species no longer occurs in as much as a third of its historic range. Because of the declines, the U.S. Fish and Wildlife Service considers the species a candidate for listing under the Endangered Species Act. Chytridiomycosis, a disease caused by the non-native amphibian chytrid fungus, rec- reational use such as pack stock grazing, climate change, and air pollution are among the factors implicated in the species decline. Scientific studies determining the importance of these and other threats are currently underway. The Yosemite toad, found only in the Sierra Nevada was a historically abundant species, occurring primarily in high- elevation wet meadows above 6,400 feet in elevation. -
MRP DEIS Volume 2: Chapters 9 Through 13 and Appendices
Analysis Topics: Natural Resources Special Status Species Special Status Species Affected Environment Special status species are plants and animals that are legally protected under the federal Endangered Species Act (ESA) of 1973 or other regulations, and species that are considered sufficiently rare by the scientific community to qualify for such status. Additional federal regulations protect special status species, including the Fish and Wildlife Coordination Act of 1934 (as amended), the Bald Eagle and Golden Eagle Protection Act, and the Migratory Bird Treaty Act. These are discussed in more detail in the paragraphs that follow. The California ESA, administered by the California Department of Fish and Game [CDFG], does not supersede the federal ESA, but operates in conjunction with it to provide additional protection to threatened and endangered species in California, as well as species that are not protected through federal regulations. In addition to threatened and endangered state-listed species, the CDFG maintains an informal list of plant and wildlife species of special concern because of population declines and restricted distributions, and/or because they are associated with habitats that are declining in California. The California Native Plant Society (CNPS) has also developed lists of plants of special concern in California. The National Park Service (NPS) makes every reasonable effort to conduct its actions in a manner consistent with relevant state laws and regulations, per NPS policy. Regulations and Policies Pertaining to Special Status Species Federal Laws and Regulations Endangered Species Act. The U.S. Fish and Wildlife Service (USFWS) has jurisdiction over species formally listed as threatened or endangered under the ESA (16 USC 1531–1544). -
