This is a dataset of forest harvest areas for the Upper North Saskatchewan and Upper Red Deer River Basins of Alberta. This dataset was created to support spatial analyses of forest harvest areas in the Upper North Saskatchewan and Upper Red Deer River Basins for the Alberta Environment and Parks report entitled “Ecological response to land use and human activities in the eastern slopes of Alberta’s Rocky Mountains: A scientific assessment”. This is a polygon dataset covering the Upper North Saskatchewan and upper Red Deer River Basins of Alberta, Canada for the period 1961-2016. This dataset of forest harvest areas was created using three data sources obtained from Alberta Agriculture and Forestry: The AVI (Alberta Agriculture and Forestry, 2017a), the Post Inventory Final Cutblocks layer (Alberta Agriculture and Forestry, 2017b), and Regional Forestry Cultblock data (obtained directly from Alberta Agriculture and Forestry, March 2018).
