of the potential for occurrence of each species is based on the distribution of <br />regional occurrences (if any), habitat suitability, and field observations. <br />SPECIAL -STATUS PLANTS: Twelve (12) species of special -status plants were <br />identified in the CNDDB (2021) search: alkali milk -vetch (Astragalus tener var. <br />tener), heartscale (Atriplex cordulata var. cordulata), big tarplant (Blepharizonia <br />plumosa), watershield (Brasenia schreberi), palmate-bracted salty bird's -beak <br />(Chloropyron plamatum), recurved larkspur (Delphinium recurvatum), San <br />Joaquin spearscale (Extriplex joaquinana), woolly rose mallow (Hibiscus <br />lasiocarpos var. occidentalis), delta tule pea (Lathyrus jepsonii var. jepsonii), <br />Sanford's arrowhead (Sagittaria sanfordii), Suisun marsh aster (Symphotrichum <br />lentum), and saline clover (Trifolium hydrophilum) (Table 3 and Attachment B). <br />No additional special -status species are identified in the USFWS IPaC Trust <br />Report (Attachment B). <br />Special -status plants generally occur in relatively undisturbed areas in vegetation <br />communities such as vernal pools, marshes and swamps, seasonal wetlands, <br />riparian scrub, and areas with unusual soils. All of the special -status plants <br />identified in Table 3 occur in habitat types that do not occur in the site. The site <br />contains ruderal grassland species that is routinely disked, The site has been <br />historically farmed for decades and is not suitable for special -status plants. Duck <br />Creek does not contain marsh or swamp habitat required by several of the <br />special -status plant species in Table 3; most of the marsh and swamp plant <br />species in Table 3 are associated with tidal marshes several miles to the west of <br />the site. No special -status plants or potentially suitable habitat for special -status <br />plants were observed in the site. Due to lack of suitable habitat, it is unlikely that <br />special -status plants occur in the site. <br />SPECIAL -STATUS WILDLIFE: Special -status wildlife species recorded in <br />project area in the CNDDB (2021) query include Swainson's hawk, tricolored <br />blackbird (Agelaius tricolor), least Bell's vireo (Vireo bellii pusillus), white-tailed <br />kite (Elanus leucurus), burrowing owl ,California tiger salamander (Ambystoma <br />3009 Pock Lane: Biology 19 November 24, 2021 <br />
