Biological Resources Evaluation Report <br /> Griffith Energy Project <br /> Scientific Common Federal State Status <br /> Name Name Status /Other Habitat Potential to Occur* <br /> Status <br /> Amphibians <br /> Medium.This species lives in vacant or mammal- <br /> occupied burrows, such as California ground squirrel <br /> burrows, during the estivation period (March- <br /> November). They also require vernal pools or other <br /> seasonal water sources for breeding.Within the 1.24- <br /> mile radius assessed for potential breeding <br /> ponds/pools,four potential breeding pools exist(Table <br /> 4). One pool was visited and determined to be a <br /> potential CTS breeding pool and three potential <br /> breeding habitats could not be observed during the <br /> survey because they occur on private property. The <br /> nearest known breeding site is 2 miles southwest from <br /> Grassland, savanna, or open the Project site(CDFW 2021 a). CNDDB search results <br /> woodland habitats. Can occur show that there are additional occurrences 3 miles east <br /> in upland areas with of the project site from 2015 and 2016, and several <br /> Ambystoma California tiger occurrences found along a road 3 miles north of the <br /> small mammal burrows)w <br /> califomiense salamander Threatened Threatened underground refuges s)within Project site in 2016(CDFW 2021 a). Ground squirrel <br /> burrows in low-sloping areas are present on the Project <br /> 1.24 miles from a breeding site and provide upland refuges for CTS.Also, the soils <br /> pond. on site are moist enough to support burrowing <br /> amphibians, such as the slender salamanders observed <br /> during the survey. While the Project site and <br /> surrounding properties within the 1.24-mile radius <br /> undergo annual grazing, this is generally thought to be <br /> compatible with successful use by CTS(USFWS 2004). <br /> Overall, lack of development south of the Project site <br /> has resulted in relatively unimpeded potential CTS <br /> migration from most potential breeding ponds in that <br /> area. Therefore, the potential for this species to utilize <br /> the Project site as upland dispersal habitat is medium. <br /> CTS would not use the Project site as breeding habitat <br /> given the lack of aquatic habitat onsite. <br /> Tetra Tech, Inc. 5-18 July 2023 <br />
