Species Rarity / Habitat Notes
Crassula connata Very low occupancy. Typically found in localised patches within a habitat patch; absent from most islands; widely dispersed across the larger islands of Vancouver and San Juan.
Meconella oregana Very low occupancy. Absent from most islands; moderately distributed on the southern tip of Vancouver Island but only known from single localities on other islands where it is highly local within a patch when found.
Perideridia montana Low occupancy. Widely distributed on the southern tip of Vancouver Island, but idiosyncratic distribution on smaller islands; often locally abundant and widely distributed within habitat patches when found; sometimes restricted to a narrower microhabitat (swales) in drier sites.
Trifolium dichotomum Low occupancy. Found on a few islands where records are highly clustered; locally abundant to common in patches where found, not widely distributed within patches when found.
Aquilegia formosa Low occupancy. Mostly found on larger islands where populations are spatially clustered, though widely distributed; preference as deer forage may mask distribution.
Castilleja attenuata Low occupancy. Sparsely distributed on smaller islands but widely distributed on the southern tip of Vancouver Island.
Plagiobothrys tenellus Low occupancy. Sparsely distributed on larger islands; often locally abundant and widely distributed within habitat patches when found.
Platanthera unalascensis Moderate occupancy. Sparsely distributed on larger islands but widely distributed on the southern tip of Vancouver Island.
Lepidium virginicum Moderate occupancy. Fairly broadly distributed across islands and habitat patches within islands, though infrequently occurring.
Primula pauciflora Moderate occupancy. Found on a few widely scattered islands; localities highly clustered within islands, where it is often locally common and widely distributed within patches when found.
