This proposal is for acquisition of high priority properties within two coastal Natural Area Preserves in Pacific County that include the Bone and Niawiakum Rivers. These coastal wetland and estuary ecosystems are the highest quality examples remaining of native coastal salt marsh communities in Washington. The superb wetlands of the Bone River and Niawiakum River preserves are recognized as national priorities for protection, as evidenced by past and current USFWS grants awarded for coastal wetland acquisition at both sites. It is critical to secure additional funding to pursue acquisition of the remaining undeveloped lands, which are threatened with conversion to incompatible and/or ecologically irreversible uses, such-as residential development.
