Potentially suitable habitat <br />occurs within the grasslands of the site, <br />however, the species was not detected <br />during a focused survey conducted in <br />May 2017 and it is presumed absent <br />from the site. There are no <br />documented occurrences within three <br />miles of the site. <br />Mt. Diablo fairy-lantern <br /> (Calochortus pulchellus) <br />CNPS 1B Habitat: Occurs on wooded <br />or brushy slopoes within <br />chaparral, cismontane <br />woodland, riparian <br />woodland, and valley and <br />foothill grasslands. <br />Elevation: 30-840 meters. <br />Blooms: Bulb; April-June. <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 />Chaparral harebell <br /> (Campanula exigua) <br />CNPR 1B Habitat: Occurs in rocky <br />chaparral, usually on <br />serpentine. <br />Elevation: 300-1250 meters. <br />Blooms: Annual herb; May- <br />November. <br />Absent. Habitat is absent on the site <br />for this species. There is one <br />documented occurrence of this species <br />in the site’s vicinity approximately <br />three miles south of the site near Niles <br />Blvd. <br />Congdon’s tarplant <br /> (Centromadia parryi ssp. <br />congdonii) <br />CNPS 1B Habitat: Occurs on valley <br />and foothill grasslands on <br />alkaline soils. <br />Elevation: 0-230 meters. <br />Blooms: Annual herb; May- <br />November. <br />Possible. The 2008 Olberding Report <br />identified a population of Congdon’s <br />tarplant on the site and LOA identified <br />three very small populations on the site <br />during their July 9, 2012 site visit; <br />however, this species has not been <br />observed on the site during surveys <br />conducted in 2014 through 2017. A <br />focused survey for this species is <br />planned in summer and fall 2017. <br />Hispid bird’s-beak <br /> (Chloropyron mollis ssp. hispidus) <br />CNPS 1B Habitats: Occurs in alkaline <br />soils in meadows and seeps, <br />playas, and valley and <br />foothill grassland. <br />Elevation: 1-155 meters. <br />Blooms: Annual; June- <br />September. <br />Absent. Habitat is absent from the site <br />for this species. There are no <br />documented occurrences within three <br />miles of the site. <br />Santa Clara red ribbons <br /> (Clarkia concinna ssp. automixa) <br />CNPS 4 Habitats: Occurs in chaparral <br />and cismontane woodland. <br />Elevation: 90-1500 meters. <br />Blooms: Annual; April-July. <br />Absent. Habitat is absent from the site <br />for this species. There are no <br />documented occurrences within three <br />miles of the site. <br />Hospital Canyon larkspur <br /> (Delphinium californicum ssp. <br />interius) <br />CNPS 1B Habitat: Occurs in chaparral <br />openings and mesic <br />cismontane woodlands. <br />Elevation: 230-1095 meters. <br />Blooms: April-June. <br />Absent. Habitat is absent from the site <br />for this species. There are no <br />documented occurrences within three <br />miles of the site.
