Conservation Evaluation of the Bog Bird's-foot Trefoil, Lotus pinnatus, in Canada

Résumé

In Canada, Bog Bird’s-foot Trefoil, Lotus pinnatus, is confined to vernally wet meadows, creek margins, ditches and seepages, where underground water comes to the surface. Seven localities, within a small area on the east coast of Vancouver Island near Nanaimo, British Columbia, have been confirmed in recent years. At two others it is considered extirpated. The lack of protection on private land, alterations to hydrology, and erosion arising from intensive recreational use of primary habitat by off-road vehicles as well as the appearance of invasive, species are the main concerns for British Columbia populations.
