Located north of Vancouver, in the Puget Trough/Willamette Valley ecoregion, this Willamete Valley wet prairie represents the only example of its size and quality in Washington. These ecosystems, which are considered priority 1 plant communities, are seriously threatened by habitat destruction and degradation in one of the most rapidly urbanizing counties in the state. These priority parcels support the second largest of 20 known populations of Bradshaw's Lomatium, a globally critically imperiled, federally-listed endangered plant species. It also contains habitat for five state sensitive plant species and one rare animal species, the Slender-billed White Breasted Nuthatch. These proposed acquisitions would constitute the first phase of a multi-phased and multi-agency effort to protect a larger area of wet prairie and oak woodland. Other partners in the effort to protect these rare communities and species include the Columbia Land Trust, Washington Nature Conservancy, U. S. Fish and Wildlife Service and Clark County.
