Pagination or Media Count:
Data on forest vegetation in western Oregon were assembled for 2323 ecological survey plots. All data were from fixed-radius plots with the standardized design of the Current Vegetation Survey CVS initiated in the early 1990s. For each site, the database includes 1 live tree density and basal area of common tree species, 2 total live tree density, basal area, estimated biomass, and estimated leaf area 3 age of the oldest overstory tree examined, 4 geographic coordinates, 5 elevation, 6 interpolated climate variables, and 7 other site variables. The data are ideal for ecoregional analyses of existing vegetation.
