24 <br />Table 2: Special status species that could occur in the project vicinity. <br />PLANTS (adapted from CDFW 2017 and CNPS 2017) <br />Other special status plants listed by the CDFG and CNPS <br />Common and scientific names Status General habitat description *Occurrence in the study area <br />Alkali milk-vetch <br /> (Astragalus tener var. tener) <br />CNPS 1B Habitat: Occurs in alkaline <br />soils within low-lying areas, <br />playas, vernal pools and <br />annual grasslands. <br />Elevation: 1-60 meters. <br />Blooms: Annual; March – <br />June. <br />Absent. The grasslands and seasonal <br />wetlands of the site provide only <br />marginal habitat for this species due to <br />an absence of highly alkaline soils and <br />this species has not been observed in <br />the vicinity since 1989. There are no <br />documented occurrences within three <br />miles of the site and this species was <br />not observed during focused surveys <br />conducted in May 2017. <br />Heartscale <br />(Atriplex cordulata) <br />CNPS 1B Habitat: Occurs in saline or <br />alkaline soils of chenopod <br />scrub, meadows and seeps, <br />and sandy valley and foothill <br />grassland. <br />Elevation: 0-560 meters. <br />Blooms: April-October. <br />Absent. Habitat is absent on the site <br />for this species. There are no <br />documented occurrences within three <br />miles of the site. <br />Brittlescale <br /> (Atriplex depressa) <br />CNPS 1B Habitat: Occurs on alkaline <br />clay soils in chenopod scrub, <br />meadows and seeps, playas, <br />valley and foothill <br />grasslands, and vernal pools. <br />Elevation: 1-320 meters. <br />Blooms: Annual herb; April- <br />October. <br />Absent. Habitat is absent on the site <br />for this species. There are no <br />documented occurrences within three <br />miles of the site. <br />Lesser saltscale <br />(Atriplex minuscula) <br />CNPS 1B.1 Habitat: Occurs in alkaline <br />and sandy soils in chenopod <br />scrub, playas, and valley and <br />foothill grasslands. <br />Elevation: 15-200 meters <br />Blooms: Annual herb; May- <br />October. <br />Absent. Habitat is absent on the site <br />for this species. There are no <br />documented occurrences within three <br />miles of the site. <br />Big-scale balsamroot <br /> (Balsamorhiza macrolepis var. <br />macrolepis) <br />CNPS 1B Habitat: Occurs in chaparral, <br />cismontane woodland, valley <br />and foothill grassland, <br />sometimes on serpentine. <br />Elevation: 90-1400 meters. <br />Blooms: Perennial herb; <br />March-June. <br />Absent. While grasslands of the site <br />provide potentially suitable habitat for <br />this species, soils of the site are not <br />serpentine and this perennial plant <br />would have been identified if present on <br />the site during the 2012 through 2017 <br />surveys, including a focused rare plant <br />survey in May 2017. There are no <br />documented occurrences within three <br />miles of the site. <br />Big tarplant <br /> (Blepharizonia plumosa) <br />CNPS 1B Habitat: Occurs in valley and <br />foothill grasslands, usually <br />on clay or clay-loam soils. <br />Elevation: 30-505 meters. <br />Blooms: Annual; July- <br />October. <br />Possible. Potentially suitable habitat <br />occurs within the grasslands of the site <br />on clay-loam soils. Properly timed <br />surveys would need to be conducted to <br />determine its presence or absence from <br />the site. A focused survey for this <br />species is planned in summer and fall <br />2017. There are no documented <br />occurrences within three miles of the <br />site.
