<br /> 28 <br />TABLE 2A: SPECIAL STATUS SPECIES THAT COULD OCCUR IN THE PROJECT VICINITY. <br />PLANTS (adapted from CDFW 2023 and CNPS 2023) <br />Species Listed as Threatened or Endangered under the State and/or Federal Endangered Species Acts <br />Common and scientific names Status <br />General habitat <br />description *Occurrence in the study area <br />Diablo helianthella <br />Helianthella castanea <br />CRPR 1B Habitat: Broadleaved <br />upland forest, chaparral, <br />cismontane woodland, <br />coastal scrub, riparian <br />woodland, valley and <br />foothill grassland. <br />Elevation: 60-1300 <br />meters. <br />Blooms: Perennial herb; <br />March–June. <br />Absent. Potentially suitable <br />habitat is present on the site, <br />however, rare plant surveys in <br />September of 2014 did not detect <br />this perennial species on the site. <br />Follow up surveys in 2016, 2017, <br />2019 and 2023 continued to fail to <br />detect this species. <br />Brewer’s western flax <br />Hesperolinon breweri <br />CRPR 1B Habitat: Usually occurs on <br />serpentine soils of <br />chaparral, cismontane <br />woodland, and valley and <br />foothill grassland. <br />Elevation: 30-900 meters. <br />Blooms: Annual herb; <br />May–July. <br />Absent. Serpentine soils are <br />absent from the site. The nearest <br />documented occurrences of this <br />species are more than eleven miles <br />northeast of the site. <br />Shining navarretia <br />Navarretia nigelliformis ssp. <br />radians <br />CRPR 1B Habitat: Occurs in <br />cismontane woodlands, <br />valley and foothill <br />grasslands, and vernal <br />pools. <br />Elevation: 76-1000 <br />meters. <br />Blooms: Annual herb; <br />April-July. <br />Absent. While potentially suitable <br />habitat is present, the nearest <br />documented occurrences of this <br />species are more than eleven miles <br />to the east of the site, and it was <br />not detected during rare plant <br />surveys. <br />Prostrate vernal pool <br />navarretia <br />Navarretia prostrata <br />CRPR 1B Habitat: Occurs in mesic <br />areas within coastal <br />scrub, meadows and <br />seeps, alkaline valley and <br />foothill grasslands, and <br />vernal pools. <br />Elevation: 15-1210 <br />meters. <br />Blooms: April-July. <br />Absent. Suitable habitat for this <br />species is absent from the site. <br />Saline clover <br />Trifolium hydrophilum <br />CRPR 1B Habitat: Marshes and <br />swamps, valley, and <br />foothill grasslands on <br />mesic or alkaline soils, <br />and vernal pools. <br />Elevation: 0-300 meters. <br />Blooms: Annual herb; <br />April–June. <br />Absent. Suitable habitat for this <br />species is absent from the site.
