Current Limited Entry Hunting (LEH) Zones polygons are hunting opportunities created via a lottery, and the details are found in the LEH Synopsis. Participation in the LEH draw is available to any resident of BC who legally possesses a BC Resident Hunter Number. The purpose of Limited Entry Hunting is to achieve wildlife management objectives without resorting to such measures as shortening seasons or completely closing areas. It is only introduced where it has become necessary to limit the number of hunters, limit the number of animals that may be taken, or limit the harvest to a certain class of animal. The Zones are valid during the LEH hunting season, and changes are made effective July 1st of each yearly. Some zones change frequently, some change rarely.
