For a treatment to be considered beneficial to <br />special-status butterfly species, the qualified RPF or biologist would demonstrate with <br />substantial evidence that habitat function is reasonably expected to improve with <br />implementation of the treatment (e.g., by citing scientific studies demonstrating that the <br />species (or similar species) has benefitted from increased sunlight due to canopy opening, <br />eradication of invasive species, or otherwise reduced competition for resources). If it is <br />determined that treatment activities would be beneficial to special-status butterflies, no <br />compensatory mitigation would be required. <br />Table 3.6-34 Special-Status Butterflies and Associated Host Plants <br />Butterfly Species Host Plants <br />bay checkerspot butterfly dwarf plantain (Plantago virginica), purple owl’s clover (Castilleja <br />exserta) <br />Behren’s silverspot butterfly blue violet (Viola adunca) <br />callippe silverspot butterfly California golden violet (Viola pedunculata) <br />Carson wandering skipper salt grass (Distichlis spicata) <br />El Segundo blue butterfly seacliff buckwheat (Eriogonum parvifolium) <br />Hermes copper butterfly spiny redberry (Rhamnus crocea) <br />Kern primrose sphinx moth plains evening-primrose (Camissonia contorta), field primrose <br />(Camissonia campestris) <br />Laguna Mountains skipper Cleveland’s horkelia (Horkelia clevelandii), sticky cinquefoil <br />(Drymocallis glandulosa) <br />Lange’s metalmark butterfly naked-stemmed buckwheat (Eriogonum nudum)
