    March 26, 2021 Theodore Payne Foundation’s Wild Flower Hotline is made possible by donations, memberships and sponsors. Please support the Hotline today! COVID-19 restrictions are still appropriate in public places and different for each county, so visit websites first in planning your trip. At Placerita Canyon Nature Center in Newhall, spring is slow in arriving for annual wildflowers. However, there is a diversity of reliable chapparal shrubs in bloom along the Canyon Trail. A hiker should seek out the pink flowering chapparal currant (Ribes malvaceum), sugarbush (Rhus ovata), and the fragrant white blossoms of hoary leaved ceanothus (Ceanothus crassifolius). Deeper in the canyon areas where more shade and moisture are available, take in the majesty of the sycamore trees (Platanus racemosa) and flowering ash (Fraxinus dipetela). Wild cucumber (Marah macrocarpa) can be seen climbing up and over the shrubs and trees to get their place in the sun. Back out in the open, sunnier locations, look for the nice purple and yellow combo of purple nightshade (Solanum parishii) and golden yarrow (Eriophyllum confertiflorum). There are also some nice patches of goldfields (Lasthenia sp.) surrounded by black sage (Salvia mellifera). If you are entering via the Walker Ranch parking area, there is a large stand of golden currant (Ribes aureum) nearby. Spring color has been found in the Santa Monica Mountains recently! Along Dirt Mulholland east of Reseda Blvd and the Marvin Braude Mulholland Gateway Park see flowering big pod ceanothus (Ceanothus macrocarpa). Purple nightshade (Solanum parishii) contrasts nicely with the bright yellow California brittle brush flowers (Encelia californica).

The proposed project is the creation of a new interchange along I-10 east of the existing Dillon Road interchange (Postmile [PM] R62.3 to R63.7). This NES includes information on the biological resources in the Biological Study Area (BSA) for the proposed project and meets the State of California Department of Transportation (Caltrans) NES guidelines (Caltrans 2009). This information has been reported in accordance with accepted scientific and technical standards that are consistent with the requirements of the U.S. Fish and Wildlife Service (USFWS), the California Department of Fish and Wildlife (CDFW), and Caltrans. The BSA for the proposed project includes the proposed impact area plus a 500-foot buffer area. The following vegetation types and other areas occur in the BSA: desert annual grassland, white bursage scrub, cheesebush scrub, allscale scrub, creosote bush scrub, creosote bush – white bur sage scrub, Mojave desert wash scrub, wand holdback (unique stand), disturbed/unvegetated, and developed. The BSA is currently open space and provides moderate to high quality desert scrub habitat for wildlife species. Alluvial washes, including Smokey Gulch, and culverts passing beneath the I-10 in the BSA currently provide wildlife crossings that connect open space located north and south of I-10.
