Suffield National Wildlife Area (SNWA) is a National Wildlife Area located within the boundaries of CFB Suffield in Alberta, Canada.
SNWA was formally created on the 19th of June, 2003 when it was officially gazetted under Canada Wildlife Act Regulations. The Department of National Defence (DND) was delegated authority to administer and control the NWA. The Base Commander is responsible for operations, management, and permitting in the SNWA.
CFB Suffield itself was created in 1971 when control of the Suffield Block was transferred from the Defence Research Establishment Suffield as part of the reorganization to support the mechanized training activities of the British Army Training Unit Suffield on the northern two-thirds of the area. The 2960 km² area of the Suffield Block was expropriated by the Province of Alberta during the Second World War on behalf of the Canadian Federal Government. The land was leased to the Federal Government for ninety-nine years at a cost of one dollar per year to support the operation of the Experimental Station Suffield. Upon the termination of the Second World War, ownership of the British Block (or Suffield Block) was transferred from the province to the federal government in exchange for a large number of army and air camps and building from the Dominion Government (War Assets Corporation).
The portion of the Suffield Block that is now the National Wildlife Area was zoned for environmental protection and included three parts: the Middle Sand Hills, the Mixed Grass Prairie zone, the South Saskatchewan River zone.
