<br />Soil Investigations for Data Collection in the Delta <br />Initial Study/Proposed Mitigated Negative Declaration 108 <br />Peruvian dodder has a CRPR of 2B.2 but is not listed under FESA or CESA. <br />This species is an annual parasitic vine in the morning glory family, and it blooms <br />from July to October (CNPS 2019). Its current range in California includes the <br />Central Valley and South Coast, and southern Outer North Coast Ranges; <br />however, the last confirmed sighting of this species in California was in 1948 <br />(CNPS 2019, Jepson Flora Project 2019). It is presumed extirpated from San <br />Bernardino County, and records from Sacramento County are of uncertain <br />identity. It typically grows in marshes and swamps (CNPS 2019). Threats to this <br />species have not been identified (CNPS 2019, CDFW 2019). Potentially suitable <br />habitat for Peruvian dodder present within the Study Area. However, this species <br />has low potential to occur within the Study Area because the Study Area is <br />located outside of its known range so potential impacts would be less than <br />significant. <br />Implementation of Mitigation Measures MM BIO-1b, MM BIO-18 and MM BIO-19 <br />would further avoid, minimize and/or reduce the potential for impacts to Peruvian <br />dodder. <br />Livermore tarplant (Deinandra bacigalupii) <br />Livermore tarplant is listed as Endangered under CESA and has a CRPR of 1B.1 <br />but is not listed under FESA. This species is an annual herb in the sunflower <br />family, and it blooms from June to October (CNPS 2019). It is endemic to <br />California, and its current range includes the northwest San Joaquin Valley <br />(CNPS 2019, Jepson Flora Project 2019). It typically grows in meadows and <br />seeps (CNPS 2019). The microhabitat for Livermore tarplant includes alkaline <br />meadows (CDFW 2019). Threats to this species include urbanization and <br />development (CNPS 2019). This species has moderate potential to occur within <br />the Study Area based on the presence of potentially suitable habitat. <br />Implementation of Mitigation Measures MM BIO-1b, MM BIO-18, and MM BIO-19 <br />would reduce potential impacts to Livermore tarplant to: Less than Significant <br />with Mitigation Incorporated. <br />Recurved larkspur (Delphinium recurvatum) <br />Recurved larkspur has a CRPR of 1B.2 but is not listed under FESA or CESA. <br />This species is a perennial herb in the buttercup family, and it blooms from March <br />through June. It is endemic to California, and its current range includes the San <br />Joaquin Valley, southern Inner South Coast Ranges, and western Mojave Desert <br />(CNPS 2019; Jepson Flora Project 2019). It is presumed extirpated from the <br />Sacramento Valley as well as from Butte and Colusa counties (CNPS 2019; <br />Jepson Flora Project 2019). It typically grows in valley and foothill grassland, <br />chenopod scrub, and cismontane woodland. The microhabitat for recurved <br />larkspur includes alkaline soils in valley saltbush and valley chenopod scrub <br />(CDFW 2019). Threats to this species include agricultural conversion, grazing,
