The permit drawings are for special hunts in select areas throughout the state. It is a way to keep some control over the harvest of certain species or genders of animals. Sheep, bear, moose and goats are the main targets of the drawings. If you want to meat hunt for a cow moose in unit 14 then a drawing is the only way to do that. No over the counter cow tags like there are doe tags in the states.
There are coveted areas for sheep and moose that get thousands of applications each year. Some guys apply for years to get a 14C sheep tag. Other get drawn for a Fort Rich archery moose tag every 4 to 5 years. Lots of folks think the system is not fair since it does not build up points for years that you apply but don't get drawn like it works in some western states for trophy deer areas.
