DRAFT Appendix A1: Ecounit Section and Subsection Attributes for Forest Service Class 1 Areas Below are four tables summarizing the climate, vegetation, and soil attributes associated with the Ecounit Sections and Subsections. Ecounit classification of the Forest Service Class 1 Areas was done by overlaying a GIS coverage of the Class 1 Areas on the DRAFT Subsection map. Once the map lines and subsection attributes are finalized, information at the subsection-level will be available for all Class 1 Areas (projected completion: spring 2005). Note that there are a few instances where Section Descriptions were not available.
