Shasta Salamander Report - June 23, 2011 Porcupine Vegetation and Road Management Project - Shasta Salamander Report - June 23, 2011 The following summary includes the best available science for Shasta salamander (Hydromantes shastae, HYSH) in regards to its range and habitat to determine whether a project would ‘trigger’ the need for pre-disturbance surveys under the Survey & Manage (SM) program of the 2001 SM ROD (USDA; USDI, 2001). Status Shasta salamander is a Region 5 Forest Service Sensitive species as well as a Survey & Manage species endemic to a small portion of the STNF (‘Category A’ SM species in the 2001 SM ROD). As a resident around the Shasta Lake reservoir and with limestone quarries in its habitat, this amphibian species is also categorized as State Threatened in California. The SM amphibian survey protocol was published in 1999 (Olson et al. 1999) prior to the former, current 2001 SM ROD. Under this outdated provision from the Northwest Forest Plan in 1994, Shasta salamander was a ‘protection buffer’ species. The geographic extent of surveys in the protocol was developed under this outdated provision. Shasta salamander no longer has the ‘protection buffer’ status in the 2001 SM ROD. In implementing the 2001 SM ROD for ‘Category A’ species, surveys would be conducted prior to signing NEPA decisions for projects that would be habitat disturbing activities (called pre- disturbance or clearance surveys). Habitat-disturbing activities are defined as those disturbances likely to have a significant negative impact on the species’ habitat, its life cycle, microclimate, or life support requirements (2001 SM ROD on S&G page 22). The line officer should seek specialists’ recommendations to help determine the need for a survey based on site-specific information of the project (2001 SM ROD on S&G page 22). In making this determination, the line officer should consider: • the probability of the species being present on the project site, as well as • the probability that the project would cause a significant negative effect on the species habitat or, • the persistence of the species at the site. These concepts are echoed in the older 1999 SM survey protocol: “surveys are triggered when the project is expected to affect suitable habitat conditions for the target species and/or the animals themselves. Site managers are expected to have the greatest discretion with regard to this final criterion.” The habitat conditions, range descriptions, and maps, described below, help to determine the need for a project pre-disturbance survey. Range and habitat Shasta salamander is a terrestrial salamander unique to a small area northeast of Redding (Olson et al. 1999) and endemic to the Shasta Lake area (Herman 2003). Shasta salamander has the smallest range of any Pacific Northwest amphibian (Herman 2003). The Shasta salamander’s type locality is: "entrance to limestone caves at the edge of Flat Creek Road in the narrows of Low Pass Creek (0.7-mile east of Squaw Creek Road, 18.4 miles north and 15.3 miles east of Redding), Shasta County, California", USA (Frost 2011, Gorman et al. 1953). The primary habitat for Shasta salamander is limestone caves and rock outcrops and slopes that surround these limestone features around Shasta Lake, Shasta County; where the majority of this salamander’s known sites are (Olson et al. 1999, Dept. Fish and Game 2008, California Herps 2011, Amphibia Web 2011). The limestone features provide summer refugia in the form of caves Shasta McCloud Management Unit – Shasta-Trinity National Forest - 1 Porcupine Vegetation and Road Management Project - Shasta Salamander Report - June 23, 2011 and crevices that hold moisture for the salamander. Shasta salamanders most likely spend the normal hot, dry summers underground (in the caves, Herman 2003). Shasta salamander has been found at volcanic rock outcrops, albeit rarely (Lewendal 1995). It primarily requires moist environments of limestone, especially in summer (Dept. Fish and Game 2008). Its elevation range is from 300-910 meters (984-2,986 feet elevation; Frost 2011, Amphibia Web 2011). Known sites are located within a 17 mile radius of O’Brien, California at Shasta Lake (Olson et al. 1999). As of March 2008, there are approximately 213 known locations distributed across wooded landscapes around Shasta Lake (Dept. Fish and Game 2008). To avoid adverse impacts on Shasta salamander, the California Department of Fish and Game recommends eliminating disturbance to and/or treatments on limestone outcrops during project planning to the extent feasible. The California Department of Fish and Game employs a project consultation boundary around Shasta Lake, which is larger than the salamander’s known range, by including convex polygons and watershed boundaries (see map below). 2 - Shasta McCloud Management Unit – Shasta-Trinity National Forest Porcupine Vegetation and Road Management Project - Shasta Salamander Report - June 23, 2011 Map of the range and distribution of Shasta salamander (Amphibia Web 2011) Shasta McCloud Management Unit – Shasta-Trinity National Forest - 3 Porcupine Vegetation and Road Management Project - Shasta Salamander Report - June 23, 2011 Map of known range of Shasta salamanders (shaded area; Herman 2003) Map of the range and distribution of Shasta salamander (California Herps 2011) 4 - Shasta McCloud Management Unit – Shasta-Trinity National Forest Porcupine Vegetation and Road Management Project - Shasta Salamander Report - June 23, 2011 Determination The Porcupine Vegetation and Road Management Project is located at least 25 miles northeast of the range of Shasta salamander. The Shasta Lake area is approximately 50 miles southwest of the project area. There is no limestone habitat in the project area. The closest limestone habitat and closest known site of Shasta salamander are approximately 25 miles from the project. The Forest Service’s corporate database, NRIS Wildlife, has no records of Shasta salamander in the project area. For these reasons, the line officer for the project has determined that the probability of Shasta salamander being present in the project area is not likely; the probability that the project would cause a significant negative effect on the species habitat is negligible; and the project would not affect the persistence of the Shasta salamander at the project site. Therefore, no Survey and Manage surveys for Shasta salamander have occurred. Debbie Derby Wildlife Biologist 6/23/2011 References Amphibia Web. 2011.

Our organizations work to protect and restore the mature forests, watersheds and native species in northwestern California. Our members and supporters deeply value the public lands and water bodies of the Shasta-Trinity National Forest, specifically the Shasta Unit of the Whiskeytown-Shasta-Trinity National Recreation Area (NRA) for its scenic, biological and cultural values. The proposed project would increase the height of the Shasta Dam by 18.5 feet. Shasta Dam is already the largest reservoir in the state and the proposed project would expand the capacity of Shasta Lake by up to 634,000 acre feet, which would inundate National Forest Lands that are within habitat of the imperiled Shasta salamander, the Shasta snow-wreath and other endemic species. The area that is proposed to be flooded also includes the ancestral territory of the Winnemem Wintu Tribe, and increasing the water capacity of the reservoir would put new demands for water on Northern California’s already strained watersheds and the communities that depend

  • The Klamath-Cascade: California’S Watershed in the Balance
    THE KLAMatH-CASCADE: CALIFORNIA’s WATERSHED IN THE BALANCE Laurie A. Wayburn with Anton Chiono INTRODUCTION SUSTAINING CALIFORNIA’s WATER SUPPLY Ensuring the future of the Klamath-Cascade forest watersheds to sustain a vital, rich, and resilient economy, ecology and people. Mounts Shasta and Lassen are iconic, defining features of California, towering skyward from one of the state’s most productive and beautiful regions: the Klamath-Cascade. Spanning almost 10 million acres, this is amongst California’s most valuable natural resource regions. Klamath-Cascade forests provide the vast majority of the state’s water. They are also the most diverse conifer forests globally and form California’s historic “timber-basket.” Now, the Region is at a crossroads. Global competition, sprawling development, and a depressed economy have the Region’s traditional, timber-based communities struggling to survive. By proxy, that timber economy paid for keeping a working forest landscape with all its resources intact, from water to wildlife to recreation. Effective from the 1850s through most of the 1900s, this proxy approach is no longer sufficient in the 21st century. With its cities growing from 300-600% in the last 2 ½ decades, the Region’s vital forest infrastructure is fragmenting and under attack. A new resource economy is needed to secure this broad base of forest services—water, timber, wood-based renewable energy, recreation, and climate stabilization—that all Californians rely on. Ruggedly beautiful, globally renowned, essential to the state’s vibrant economy and highly threatened—the future of the Klamath-Cascade is in our hands. 2 FOREST The Klamath-Cascade landscape is the most productive, diverse conifer forest on earth.
