Hypothetical question: If predators were drastically reduced in a given area for the purpose of increasing moose numbers would you be willing to shoot calves?
I ask because the natural dynamic between predators and ungulates is self-reinforcing. Healthy cows typically drop twins yet you rarely see a cow with more than one calf in January. Why is that?
Roughly 75% of all moose calves don't live to see their first birthday. Most are eaten in their first month of life. Some fall to predation their first summer and the rest are taken by winter. Moose reproduction has evolved in response to, and in service of predators. They "know" that bears and wolves will take many and so they birth surplus individuals to occupy the predators allowing the others to escape. We must also bear in mind that the term carrying capacity relates to winter range conditions. When species are in balance the predation side of the equation checks herd size so that the habitat isn't over browsed and damaged.
When we hunt large bulls exclusively, or at least nearly so, we disrupt and extend the rut. This draws younger bulls into the breeding pool which stresses them before they are mature and increases their winter mortality and it causes more cows to not be bred during the their primary estrous cycle.
Come spring instead of 80-90% of calves being born essentially at once we get a significant second and even third calving period. This increases the aggregate calf crop's exposure to predation.
Back to the original question: If predators were effectively supressed in your hunting area and the moose population expanded greatly would you be willing to take those surplus calves out of the population?
