The Fish and Wildlife Enforcement Regions dataset is comprised of the polygons representing Fish and Wildlife Enforcement Regions in Alberta. Alberta Public Safety and Emergency Services, Government of Alberta, manages the Fish and Wildlife enforcement services to provide the public and other government departments' information regarding the locations of Fish and Wildlife Enforcement Regions throughout the province.

The Wildlife Management Unit (WMU) dataset is comprised of all the polygons that represent the Wildlife Management Units in Alberta. WMU is an area of wildlife managed under Wildlife Act, Alberta Regulation 143/79.

Wildlife Key Areas (WKA) are locations used by wildlife for critical, seasonal life functions. WKAs are identified by interpreting observed locations of wildlife at key times of year, not through intensive habitat assessment. Polygons derived from interviews with locals and from GIS interpretation of wildlife/habitat surveys. GIS interpretation follows criteria specific for taxon and/or populations of taxon. Key Areas are based on observed locations of wildlife at key times of year, not on habitat assessment. With new information, boundaries and designations of Key Areas can change and additional Key Areas can be identified. Furthermore, Key Areas are not the only sites important for wildlife. Other information sources can identify other sites important for wildlife for reasons outside the scope of the WKA Inventory Program. Updates to Key Areas occur only periodically. For the most current information, please consult with the Regional Biologist for your area of interest. If you have questions or would like to contribute to the WKA database, please contact the WKA Inventory Program ( [wka@yukon.ca](mailto:wka@yukon.ca) ).Distributed from [GeoYukon](https://mapservices.gov.yk.ca/GeoYukon/) by the [Government of Yukon](https://yukon.ca/) .
