Soil Investigations for Data Collection in the Delta Initial Study/Proposed Mitigated Negative Declaration 105 roadsides (CDFW 2019). Threats to this species include development, habitat alteration and disturbance, grazing, and road maintenance (CNPS 2019). This species has moderate potential to occur within the Study Area based on the presence of potentially suitable habitat. Implementation of Mitigation Measures MM BIO-1b, MM BIO-12, MM BIO-18, and MM BIO-19 would reduce potential impacts to Parry’s rough tarplant to: Less than Significant with Mitigation Incorporated. Hispid salty bird's-beak (Chloropyron molle ssp. hispidum) Hispid salty bird’s beak has a CRPR of 1B.1, but it is not listed under FESA or CESA. This species is an annual hemiparasitic herb in the broomrape family, and it blooms from June through September (CNPS 2019). It is endemic to California, and its current range includes the Central Valley (CNPS 2019; Jepson Flora Project 2019). It typically grows in meadows and seeps, playas, and valley and foothill grassland (CNPS 2019). The microhabitat for hispid salty bird’s beak includes alkaline soils (CDFW 2019). Threats to this species include agricultural conversion, development, and grazing (CNPS 2019). This species has moderate potential to occur within the Study Area based on the presence of potentially suitable habitat. Implementation of Mitigation Measures MM BIO-1b, MM BIO-18, and MM BIO-19 would reduce potential impacts to hispid salty bird’s-beak to: Less than Significant with Mitigation Incorporated. Soft salty bird's-beak (Chloropyron molle ssp. molle) Soft salty bird’s beak is listed as Endangered under FESA and Rare under CESA, and it has a CRPR of 1B.2. This species is an annual hemiparisitic herb in the broomrape family, and it blooms from June through November (CNPS 2019). It is endemic to California, and its current range includes the northern Central Coast and the Sacramento-San Joaquin Delta region of the Central Valley (CNPS 2019; Jepson Flora Project 2019). It is presumed extirpated from Marin, Sacramento, and Sonoma counties. It typically grows in coastal saltmarshes and swamps (CNPS 2019). The microhabitat for soft salty bird’s beak includes coastal saltmarsh with Distichlis, Salicornia, and Frankenia (CDFW 2019). Threats to this species include non-native plants, erosion, feral pigs, trampling, urbanization, and marsh drainage (CNPS 2019). Potentially suitable habitat for soft salty bird’s-beak is present within the Study Area. However, this species has low potential to occur within the Study Area because the Study Area is located on the edge of its known range and there is limited salt-marsh habitat in the Study Area so potential impacts would be less than significant. Implementation of Mitigation Measures MM BIO-1b, MM BIO-18, and MM BIO-19 would further avoid, minimize and/or reduce the potential for impacts to soft bird’s-beak.
