<br />Soil Investigations for Data Collection in the Delta <br />Initial Study/Proposed Mitigated Negative Declaration 125 <br />from the South Coast region, including Orange and Ventura counties. It typically <br />grows in shallow freshwater marshes and swamps (CNPS 2019). The <br />microhabitat for Sanford’s arrowhead includes standing or slow-moving <br />freshwater ponds, marshes, and ditches (CDFW 2019). Sanford’s arrowhead is <br />threatened by grazing, development, recreational activities, non-native plants, <br />road widening, and channel alteration and maintenance (CNPS 2019). This <br />species has moderate potential to occur within the Study Area based on the <br />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 Sanford’s arrowhead to: Less than Significant <br />with Mitigation Incorporated. <br />Marsh skullcap (Scutellaria galericulata) <br />Marsh skullcap has a CRPR of 2B.2, but it is not listed under FESA or CESA. <br />This species is a perennial rhizomatous herb in the mint family, and it blooms <br />from June through September (CNPS 2019). The current range of this species in <br />California includes the northern High Sierra Nevada, Modoc Plateau, and the <br />Sacramento-San Joaquin Delta region of the Central Valley (CNPS 2019; Jepson <br />Flora Project 2019). It typically grows in lower montane coniferous forest, <br />meadows and seeps, and marshes and swamps (CNPS 2019). The microhabitat <br />for marsh skullcap includes swamps and wet places (CDFW 2019). Marsh <br />skullcap is threatened by hydrological alterations, recreational activities, and non- <br />native plants (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 marsh skullcap to: Less than Significant with <br />Mitigation Incorporated. <br />Side-flowering skullcap (Scutellaria lateriflora) <br />Side-flowering skullcap has a CRPR of 2B.2, but it is not listed under FESA or <br />CESA. This species is a perennial rhizomatous herb in the mint family, and it <br />blooms from July through September (CNPS 2019). The current range of this <br />species in California includes the Sacramento-San Joaquin Delta region of the <br />Central Valley, and Saline Valley in the Great Basin (CNPS 2019; Jepson Flora <br />Project 2019). It typically grows in meadows and seeps, and marshes and <br />swamps (CNPS 2019). The microhabitat for side-flowering skullcap includes wet <br />meadows and marshes, and on logs in the Sacramento-San Joaquin Delta <br />(CDFW 2019). There are no listed threats to this species (CNPS 2019). This <br />species has moderate potential to occur within the Study Area based on the <br />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 side-flowering skullcap to: Less than <br />Significant with Mitigation Incorporated.
