Weeds

 
  Bromus diandrus Roth. Rip Gut Brome. WEED. Ala
  Cynodon dactylon (L.) Pers. Bermuda Grass. WEED. Ala
  Salsola soda L. Alkali Russian Thistle. WEED. Ala BFI
  Brassica nigra (L.) W. D. J. Koch. Black Mustard. WEED. Trs
  Cakile maritima Scop. European Sea Rocket. WEED. BFI
  Lepidium latifolium L. Broad-Leaved Pepper-Grass. WEED, priority: High. Ala
  Acacia dealbata Link (Silver Wattle)
  Acacia dealbata (Silver Wattle) is a tree (family Fabaceae) found in the coastal ranges, San Francisco Bay area, and south coast of California. It favors disturbed places in coastal prairies, riparian areas and coniferous forests. Silver wattle is often confused with green wattle (Acacia decurrens), but is distinguishable by the small, silvery hairs that grow on its twigs. It spreads via rhizomes and seeds, and easily resprouts after being cut. Acacia dealbata changes soil chemistry by fixing nitrogen, and the plantsí fallen leaves may have allelopathic effects that prevent the growth of native understory plants. Like many acacias, silver wattle is commonly planted as an ornamental.
  Lotus corniculatus L. Bird's Foot Trefoil. WEED, priority: Moderate. BFI
  Medicago polymorpha L. Bur Clover. WEED. BFI
  Marrubium vulgare L. Horehound. WEED. Ala
  Centaurea solstitialis L. Yellow Star-Thistle. WEED, priority: High. Trs
  Centaurea solstitialis (yellow starthistle) is a bushy winter annual (family Asteraceae) that invades 12 million acres in California. Yellow starthistle inhabits open hills, grasslands, open woodlands, fields, roadsides, and rangelands, and it is considered one of the most serious rangeland weeds in the state. It propagates rapidly by seed, and a large plant can produce nearly 75,000 seeds. Several insects from the Mediterranean region, including weevils and flies, have been employed as biocontrol agents for yellow starthistle with minor success.
  Dittrichia graveolens (L.) Greuter. Stinkwort. WEED, priority: Moderate. Trs
  Dittrichia graveolens (stinkwort) is a fall-flowering, sticky aromatic annual (family Asteraceae) that appears to be rapidly expanding its range in California.
