,FOIVEG_PUB_POLY: Forest Operations Vegetation Inventory Polygon feature class is a forest centric classification of vegetation with polygons that cover 100 % of western Oregon BLM lands. It describes forested lands in great detail and non-forest lands with broad and general classifications. For a complete description of this data and its structure see the FOI Vegetation Spatial Data Standard.,

Ecosections are areas with minor physiographic and macroclimatic or oceanographic variations. There are 114 ecosections in British Columbia varying from pure marine units to pure terrestrial units. Ecosections are meant to be mapped at small scales (1:250,000) for resource emphasis and area planning

Ecodivisions are areas of broad climatic and physiographic uniformity, defined at the continental level.

An ecoregion is an area with major physiographic and minor macroclimatic or oceanographic variation. There are 43 ecoregion in British Columbia of which 39 are terrestrial. Ecodivsions are meant to be mapped at 1:500,000 for regional strategic planning

Ecodomains are areas broad climatic uniformity, defined at the global level

The Phase 2, or Detailed, Forest Inventory is the second provincial level forest inventory conducted in the province of Alberta. The Phase 1 (Broad Scale) Forest Inventory (initiated in 1949 and completed by 1956) preceded the Detailed Inventory. The Phase 2 (Detailed) Forest Inventory was undertaken to cover lands where commercial timber commitments existed that were not inventoried as part of the Phase 1 (Broad Scale) Forest Inventory. The Phase 2 (Detailed) Forest Inventory utilized aerial photography from 1956 to 1966 to capture attribution similar to the Phase 1 (Broad Scale) Forest Inventory but at a more detailed level. A minimum stand size of 16.2 ha (40 acres) was used and the information was largely mapped at a scale of 1:31 680. Detailed information collected through the Phase 2 Inventory included species composition, stand density, stand heights, site class and the maturity or year of stand establishment. Cover type volume tables (CTVT) were developed, each applicable to different regions of the inventory area. Volume estimates were available by: cover type, species, and diameter class. The eastern slopes portion of the province from Township 2 to Township 47 that had never been captured by the Phase 1 (Broad Scale) Forest Inventory was mapped at the scale of 1:15 840. These maps are not available as geo-referenced rectified images or GIS-ready data.
