Nice bio-babble, but the fact is the units in the Mat-Su valley are seriously below carrying capacity for an average year. When the population is way down it is time to limit the bull kill to achieve a better bull:cow, not increase the cow kill.
Not enough browsers allows the willows (especially) to outgrow their usefulness as browse and reduce the carrying capacity. As a kid I saw the Knik River flats absolutely covered with moose every winter. We are not within an order of magnitude of those days in the moose population.
