Description

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.
