Siletz Estuary Plant Community Mapping - Tabular Data, 2001

Tabular dataset for Siletz Estuary Plant Community Mapping survey, 2001.

This study mapped twelve wetland plant communities (or “alliances”) and 59 subcommunities (or “community elements”) in 252 ha (623 A) of tidal and formerly tidal wetlands within the Siletz estuary. The target shapefile polygon size for the GIS mapping project was 0.8 to 2 ha (1 to 5 A). Within the study area, plant communities (as generally defined by estuarine ecologists) tended to occupy larger areas (over 2 ha). Therefore, each polygon was assigned both to a plant community, and to a smaller, more closely defined "subcommunity" that was characterized by a particular group of dominant plant species. The average size of a polygon (subcommunity) on the final map was about 1.5 ha (3.7 A), but about a third of the polygons were under 0.8 ha (2 A) in size.
