Biological Resources Evaluation Report Griffith Energy Project Scientific Common Federal State Status Name Name Status /Other Habitat Potential to Occur* Status High.This species has been previously documented in the southwest corner of the Project site in June 2007 Coastal prairie, coastal scrub, (CDFW 2021 a). The most recent occurrences are also Great Basin grassland, Great the two closest occurrences: two observations 1 mile Athene Basin scrub, Mojavean Desert from the Project site in 2012 and 2014 (CDFW 2021 a). cunicularia Burrowing owl BCC SSC scrub, Sonoran Desert scrub, Within a 5-mile radius of the Project site, the CNDDB and valley and foothill has 44 previous occurrences of this species (CDFW grassland. 2021 a).Although no BUOW sign was found on the Project site at the time of survey, several burrow networks which could support BUOW were found onsite. Therefore, potential to occur is high. Observed.This species was observed flying overhead over the Project site during the survey.This species is Open grasslands, sagebrush known to frequent areas of the San Joaquin valley Ferruginous flats, desert scrub, low foothills where burrowing small mammals are present during the Buteo regalis hawk BCC WL and fringes of pinyon and winter season. Due to the number of California ground juniper habitats. squirrels present on the Project site,this species may use this area to hunt prey. The ferruginous hawk does not nest in the San Joaquin Valley and therefore,will not nest in the vicinity of the Project site. Low in Project site and medium in 0.5-mile buffer. This species has been previously documented approximately 4 miles from the Project site in 1994 (CDFW 2021 a). The most recent occurrence was of a nesting pair 4.5 miles east of the Project site in 2016 (CDFW 2021 a). Tree stands in Patterson run are suitable for Swainson's hawk nesting. Transmission Great Basin grassland, towers surround the Project site in all directions and are Buteo Swainson's riparian forest, riparian also suitable sites for nesting (Figure 8). In addition, swainsoni hawk BCC Threatened woodland, valley and foothill trees suitable for nesting are found north of the Project grassland. site, on the borders of residential areas.This species could use the Project site as foraging habitat, but there is a low potential for this species to nest in the Project site due to the level of human activity near the only trees on the Project site. Therefore,there is medium potential for this species to occur in the 0.5-mile buffer and low potential for this species to occur in the Project area. Tetra Tech, Inc. 5-21 July 2023
