Status of the Golden Paintbrush, Castilleja levisecta (Scrophulariaceae) in Canada

Abstract

In Canada, Golden Paintbrush, Castilleja levisecta, has been collected on southeastern Vancouver Island and some adjacent small islands. Populations at two sites have been confirmed in recent years while the species has probably been extirpated at seven previous collection sites. The confirmed populations collectively represent the northern range limit of C. levisecta. Threats to the two confirmed populations include marine oil disasters and increasing presence of introduced species.
