Scotch broom, Cytisus scoparius (L.) Link, is an exotic weed which poses a serious threat to forested and other landscapes in southwestern British Columbia. This exotic weed has several characteristics which promote its invasiveness and displacement of native plant species: reduced leaves, active stem photosynthesis, nitrogen fixation, profuse seed production, rapid vertical growth, adaptability to various ecological niches, and lack of natural enemies. There is little data on the impact of broom on conifers in British Columbia. Therefore, two experimental sites were established on southern Vancouver Island to determine the nature and extent of invasiveness of Scotch broom in forested areas, and its impact on coniferous crop trees and other plant communities. Details and future prospects for investigation are discussed.
