In over 40 years of hunting Alaskas I've learned the realities encountered by hunters are varied and difficult if not impossible to measure even in controlled studies.  Techniques must be applied in areas of the state that differ in terms geography and population densities. My relatives on the Kenai have seen conflicts between fed and state game managers that created wide disparities in management practices. The Feds let the brown bear population grow unchecked to the point where bears had wiped out most of the moose and were coming into residents yards looking for food on a regular basis. Something not seen in over 60 years of homesteading in Kasilof. Common sense finally won out and  a provision allowing the taking of brown bears on bait stations has resulted in a large spike in brown bear harvests and a return to a reasonable balance to both prey and predator populations in that area. Sometimes these harvest techniques are distasteful but IM can work and sb utilized carefully.
