The Forest Reserve Range Distribution Units dataset represent the functional grazing management areas within the Rocky Mountains Forest Reserve. Boundaries of the allotments and/or distribution units may be defined by fencelines, height of land, natural boundaries, and/or a combination of these. This is currently the most accurate representation of the distribution unit boundary and is subject to change. In some cases these boundaries may extend beyond the boundary of the Rocky Mountains Forest Reserve. In these cases this is a representation of the management unit as a whole.

This data collection contains various historical features within Alberta related to the Dominion Forestry Branch (DFB), and the early days of the Alberta Forest Service (AFS). The data collection consists of the following: Historical Forest Reserve Boundaries (1900 to 1930). Timber Berth boundaries (1910 to 1923). Early Ground and Aerial Fire Patrol Routes. Air Stations (1920s). Locations of DFB Forest Surveys (1910 to 1915). AFS Forest and District Boundaries (circa 1938). These datasets provide approximate locations of the features they represent and are intended for use in medium to small-scale mapping. No spatial accuracy tests were conducted on any of the data. Features derived from land locations tied in the Alberta Township System (ATS) are likely to be accurate providing there were no errors in transcribing the locations. However features digitized from old maps will have poor spatial accuracy ranging from several kilometres to a few hundred metres, depending on the map scale, map projection, and the accuracy of the features on the source map.
