Recovery Strategy for Multi-Species at Risk in Vernal Pools and other Ephemeral Wet Areas Associated with Garry Oak Ecosystems in Canada Parks Canada

Abstract: This multi-species Recovery Strategy addresses recovery of six endangered plant species inhabiting vernal pools and other ephemeral wet areas: bog birdís-foot trefoil (Lotus pinnatus), tall woolly-heads (Psilocarphus elatior), Juncus kelloggii (Juncus kelloggii), Ranunculus alismifolius var. alismifolius (water plantain-buttercup), rosy-owl clover (Orthocarpus bracteosus), and dwarf sandwort (Minuartia pusilla). In Canada, these species occur (or occurred) primarily in Garry oak and associated ecosystems on Vancouver Island and Gulf Islands where they are largely restricted to low elevation coastal areas. The range of all species extends into the U.S., many of the species are widely disjunct from those populations. The Recovery Strategy is one component of the recovery program for Garry oak and associated ecosystems as outlined in the Recovery Strategy for Garry Oak and Associated Ecosystems and their Associated Species at Risk in Canada: 2001-2006. Four main habitat types are distinguished: vernal pools, vernal swales, vernal seeps, and seasonally wetted wetland margins. These habitats are all naturally highly fragmented, small isolated patches along shorelines and on small islands. Urbanization has intensified the natural fragmentation, and species occurring within them face an array of threats. Long-term goals for recovery of each species include maintaining existing populations at current levels of abundance or greater, restoring species to their approximate historical area of occupancy and extent of occurrence, and ensuring long-term population viability. Further information is needed on species distribution, populations; demography and population dynamics, vernal pool distribution/status; restoration targets; microsite attributes; optimal disturbance regimes; response of habitats and species to restoration activities; seed storage/propagation techniques and impacts of climate change.
