Abstract: This management plan has been developed to provide guidance for the British Columbia (B.C.). populations of Vancouver Island beggarticks (Bidens amplissima).The Vancouver Island beggarticks is a wetland annual plant that blooms in August through September. Plants are erect and branched, 50 to 100 cm tall, with bright yellow daisy-like flowers. The habitat for this species is the narrow edge of wetlands, estuaries, ditches, and field depressions where water tables fluctuate. The Vancouver Island beggarticks is found only in southwestern B.C. including Vancouver Island. Of the 59 locations recorded in BC, there are 38 currently extant known populations and 2 extirpated and 19 likely extirpated populations. Vancouver Island beggarticks was designated as Special Concern by the Committee on the Status of Endangered Wildlife in Canada because of declines in populations and restricted distribution. It is listed as Special Concern in Canada on Schedule 1 of the Species at Risk Act (SARA). In B.C., the Vancouver Island beggarticks is ranked S3 (vulnerable) by the Conservation Data Centre and is on the provincial Blue list. The B.C. Conservation Framework ranks the Vancouver Island beggarticks as a priority 1 under goal 1 (contribute to global efforts for species and ecosystem conservation) and goal 2 (prevent species and ecosystems from becoming at risk). Threats to Vancouver Island beggarticks include competition from invasive plants (e.g., reed canarygrass [Phalaris arundinacea] and purple loosestrife [Lythrum salicaria]), mowing, infilling of wetlands by development, alteration of hydrological regimes, and natural succession. The management goals are: 1.To maintain or increase the distribution and abundance of all extant populations in B.C., including any new populations that may be identified. 2.To re-introduce and restore populations where feasible at protected wetland locations with suitable habitat within the species range in B.C. .....
