The current assessment focused on several plant families and included terrestrial, wetland and aquatic plants. The earliest records for these species was based primarily on information gathered from herbariums at the Royal British Columbia Museum and the University of British Columbia. The first known collections in British Columbia for most of the weeds identified in this assessment were between the end of the nineteenth century and...
