Field data for the Vegetation Mapping Inventory Project of Ebey's Landing National Historic Reserve

This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. During the vegetation classification of Ebey’s Landing National Historical Reserve, we inventoried 51 alliances or associations, of which 31% were forests and woodland communities, 57% were shrublands and herbaceous types, and 10 % were agricultural or developed types. The long and varied history of human land use at Ebey’s Landing National Historical Reserve has resulted in ruderal classification for nearly one third of the forest, woodland, shrubland, and herbaceous types. Ruderal types are dominated by novel combinations of native and non-native vegetation due to human disturbance. The Reserve is home to seventeen plant associations considered critically imperiled or imperiled in the state of Washington, or globally. These communities include dry forests or woodlands restricted to a limited range in the rain shadow zone of the Puget Sound basin, remnant and restoration prairie types, rare wetlands, a salt marsh type, and a fen. Each vegetation type within the Ebey’s Landing National Historical Reserve was mapped to at least the alliance level and most were mapped at the association level of the National Vegetation Classification system. The map shows that the Reserve is 59% cultural or unvegetated, roughly split between the pasture and agricultural fields map class and the combined high and low density housing map classes. A third of the Reserve is forest and woodlands.
