Figure 1 illustrates the location of these parks on the Quimper Peninsula. Vegetation data was collected for all the mapped vegetation types. This report summarizes the activities and findings of the contracted work. Figure 1. Overview of Fort Worden, Lake Anderson, and Old Fort Townsend State Parks. 5 Survey Routes Figure 2.

Survey Routes for Old Fort Townsend State Park. 7 Vegetation Communities Methods Vegetation communities within Fort Worden, Lake Anderson and Old Fort Townsend State Parks were delineated and classified using a combination of field survey and remote sensing techniques. We relied on descriptions from the Washington State Department of Natural Resources (WADNR) late-seral forested plant associations of the Puget Lowland (Chappell, 2004), baseline inventory of rare, threatened and endangered plant species/communities along Washington’s Pacific coast (Kunze and Cornelius, 1982) and freshwater wetland vegetation (Kunze, 1994) to make final vegetation community assignments. In some cases, the WADNR descriptions were not adequate in describing existing vegetation associations. In these cases, alternative vegetation communities or plant associations were created by PBI or found in alternative reference material. Remote sensing techniques consisted of manually delineating plant associations or mosaics of plant associations in a digital environment. We reviewed orthorectified aerial photography from the 1990s and recent ASTER and LANDSAT Thematic Mapper satellite images for discernable vegetation or landform patterns. When available, we also used high resolution true color orthorectified aerial photography. Topographic maps, digital elevation models (DEMs), and light detection and ranging imagery (LIDAR) were also employed to assist the process of vegetation community delineation. The final vegetation polygons were created by hand in a GIS by ocular assessment. Field surveys consisted of visiting sites located within the vegetation polygons created during the remote sensing process. At representative sites within a polygon, vegetation data and site descriptions were recorded in a fashion consistent with the “plant community polygon” format provided by the Washington State Parks and Recreation Commission. Further refinements and editing of the drafted vegetation polygon layers were done by hand on hardcopy maps in the field, and later edited digitally in a GIS. Results We mapped and surveyed 79 vegetation community polygons, comprised of 28 vegetation community types, within Fort Worden, Lake Anderson and Old Fort Townsend State Parks. Vegetation community polygons are either stand-alone plant associations or mosaics of multiple plant associations. Tables 1 - 3 list the plant associations and/or cover types found in Fort Worden, Lake Anderson and Old Fort Townsend State Parks. See Appendix B for interpretation of “Status” codes. Figures 4 through 10 illustrate the location of the vegetation community polygons. Note that Figures 6, 8 and 10 only show the primary plant associations in each polygon (PA1 in the database). A printout of the complete set of data we collected for each polygon is attached in Appendix D. The ecological condition of each polygon was evaluated according to a simple ranking system described in Appendix C. 8 Table 1.
