Abstract
Scotch broom, Cytisus scoparius (L.) Link, is an introduced perennial noxious weed infesting over 75,000 acres throughout 18 northern counties in California. It is an unpalatable invader of range and timber lands, and a deterrent to seedlings of some coniferous tree species. It also burns with such intense heat that many forest trees may be killed by a Scotch broom fire.
