California Rangelands Web Site weed information
Most annual rangeland plants invaded during the colonization of California and displaced the native vegetation. Scientists have attempted to reverse this change will little success.
While restoration ecologists consider all of these species invasive many are important forage plants that support California's range livestock industry including wild oats, soft chess brome, annual ryegrass, filaree, rose clover and vetch.
As state and federal regulations reduce the use of herbicides and fire for weed and brush control, grazing and browsing for vegetation management is becoming more important.
