<br />Soil Investigations for Data Collection in the Delta <br />Initial Study/Proposed Mitigated Negative Declaration 97 <br />there are fewer than 10 statewide extant occurrences, the soil investigation <br />will not be allowed to proceed at that location. <br />MM BIO-19: Botanical Considerations for Vegetation Removal <br />If access requires minor disturbances to or removal of vegetation, a qualified <br />botanist will be consulted to ensure that no special-status vegetation is <br />significantly impacted. <br /> <br />Bent-flowered fiddleneck (Amsinckia lunaris) <br />Bent-flowered fiddleneck has a CRPR of 1B.2, but it is not listed under FESA or <br />CESA. This species is an annual herb in the forget-me-not family, and it blooms <br />from March to June (CNPS 2019). It is endemic to California, and its current <br />range includes the North Coast Ranges, southwest Sacramento Valley, Central <br />Coast, and San Francisco Bay Area (CNPS 2019, Jepson Flora Project 2019). It <br />typically grows in coastal bluff scrub, cismontane woodland, and valley and <br />foothill grassland (CNPS 2019). The microhabitat for bent-flowered fiddleneck <br />includes gravelly slopes, grassland, and openings in woodland, often on <br />serpentine soils (Jepson Flora Project 2019). Bent-flowered fiddleneck is <br />threatened by development, competition from non-native plants, and mining <br />(CNPS 2019). Potentially suitable habitat for bent-flowered fiddleneck is present <br />within the Study Area. However, this species has low potential to occur within the <br />Study Area because the Study Area is located outside of its known range so <br />potential impacts would be less than significant. <br />Implementation of Mitigation Measures MM BIO-18 and MM BIO-19 would further <br />avoid, minimize and/or reduce the potential for impacts to Bent-flowered <br />fiddleneck. <br />California androsace (Androsace elongata ssp. acuta) <br />California androsace has a CRPR of 4.2, but it is not listed under FESA or CESA. <br />This species is an annual herb in the primrose family, and it blooms from March <br />to June (CNPS 2019). The current range of this species in California includes <br />the Inner North Coast Ranges, Cascade Ranges, southern Sierra Nevada <br />Foothills, Central Valley, San Francisco Bay Area, Inner South Coast Ranges, <br />South Coast, Western Transverse Ranges, San Bernardino Mountains, and <br />Peninsular Ranges (CNPS 2019, Jepson Flora Project 2019). It typically grows <br />in chaparral, cismontane woodland, coastal scrub, meadows and seeps, pinyon <br />and juniper woodland, and valley and foothill grassland (CNPS 2019). The <br />microhabitat for California androsace includes dry, grassy slopes (Jepson Flora <br />Project 2019). Threats to this species include grazing, trampling, non-native <br />plants, alteration of fire regimes, recreational activities, and wind energy <br />development (CNPS 2019). This species has moderate potential to occur within <br />the Study Area based on the presence of potentially suitable habitat.
