74 - Historical Forest Inventory - Phase 1 (Broad Scale) Maps

Description

The Phase 1 (Broad Scale) Forest Inventory was initiated in 1949 and completed by 1956. The Phase 1 (Broad Scale) Forest Inventory included all publicly owned forested lands in the province except Indian lands, national parks, and an area known as the Rocky Mountains Forest Reserve. The Phase 1 (Broad Scale) Forest Inventory was used to define lands suitable for agriculture, to determine timber harvest levels and plan forest protection and timber and industrial development. Through aerial photo interpretation, land was classified as productive, potentially productive, or non-productive. On productive forest land, homogeneous groups of trees were classified by 'cover types'. Cover types included crown density, height and tree species. Burned, harvested or cultivated land was identified as potentially productive. Non-productive lands included areas with organic soils, barren rock and lakes. No ages or site classes are associated with the polygons. The minimum polygon size was 65 ha. These maps are not available as geo-referenced rectified images or GIS-ready data.
