Year of origin for both natural and managed stands.

Size classification. Size class of layer 1 (r6 size class codes). The predominant size class of all trees in a given layer of a stand based on diameter at breast height, with a minimum height of 6" for size class 1. Note: size class information is sparse for managed stands. This information is best for natural stands.

Species 1 (major species). Most abundant tree species in primary canopy layer in a managed or natural stand (pnw6 char plant code) within National Forest land.
Species 2 (minor species). Second most abundant tree species in secondary canopy layer in a manged or natural stand (pnw6 char plant code) on National Forest land.
Number of layers. Estimated number of canopy layers in the stand for forested stands.

Commercial thin year. Year of the last commercial thinning activity record.
Timber type. Timber types are classifications of stand species composition from the original timber inventory used in the development of the Forest Plan. These classifications, in association with timber size, are used to identify the correct yield table for ASQ and PSQ calculations. (INTERIM FIELD).

Condition class (INTERIM FIELD). Classification based on size class for natural stands & managed stands with non-regenerative harvest (partial) cuts for clearcuts, overstory removals & partial cuts with evidence of regeneration.
Willamette National Forest data dictionary
Land cover. Land cover classification divides the land surface into categories based upon feature of the earth surface (vegetation, rock, ice/snow,water, etc.)
Land use. Land use classification divides the land surface into categories based on the way the land is used (green tree retention, special habitats, buildings, etc.) This is a multiple field.

Habitat features. Habitats with distinct features that occur in stand which my be important when considering management practices.
Cover percent of trees. The percent of ground area covered by the vertical projection of live foliage of all trees in all tree layers in a stand. Small openings in the canopy are included. Overlapping foliage is counted only once. Canopy cover cannot exceed 100%. See vegis data dictionary for examples.

Plant association. The potential natural plant community, defined as discrete, recurring collections of plant species which maintain stable populations over a long period of time. In some cases only a general classification of plant association is known for a polygon. These polygons are coded with a 2 character code and general description. Codes beginning with "A" will be migrated to "land_use." Codes ending in C0 (zero) were sometimes coded as CO in the database. This error will be corrected, but queries for that information need to include CO and C0.
Land ownership on Willamette National Forest within the proclamation boundary.

The VEG table exists in both Oracle and INFO databases. It was originally developed from queries of the district VEGIS database (oracle) and then transferred to INFO and attached to the VEG layer in GIS. Most attention was given to populating the following fields: yr_origin, size_class, land_use, land_cover, and activity. No attempt was made to ensure that all other fields were populated. This forestwide coverage was compiled from district data July, 2000. Forestwide coverages are compiled from district information as needed, on average every 6 months. The currency of data for individual polygons varies across the forest depending on district update and edit cycles.
