Outfitting Concessions (OCs) which are also known as Outfitting Areas, are legal boundaries that define an area where the holder of the concession has the exclusive right to outfit non-residents for the purpose of hunting big game animals (excepting special guiding licenses). If a non-resident wishes to hunt in the Yukon they must do so accompanied by a Yukon resident--either a private individual who does this for free, or a commercial operator who does this as a business(an outfitter). Each outfitter is licensed to operate within a particular OA. There are 20 such concessions in the Yukon--one per licensed outfitter. OCs are largely (but not always) defined by groupings of Game Management Areas. There are several areas within the Yukon (exclusive of National Parks) which are not covered by OCs. This data was built using the 1:250,000 National Topographic Data Base (NTDB) as the digitizing base.
