[QUOTE="BSK, post: 5429705, member: 17"] Doe removal - hence population stabilization or reduction - is only needed if the habitat cannot support the local population. Evidence of this would be 1) severe browse-lines on most food sources, 2) low fawn survival, 3) low body weights of adult deer, 4) high natural mortality rates, as most deer in an overpopulated herd do not die of starvation, they die of malnutrition-related diseases. Just remember, some habitat can support a lot of deer in a relatively healthy manner. Some habitats cannot support even a low deer density in a healthy manner. EVERYTHING is based on habitat quality. But as the deer density increases, habitat quality declines, as more mouths eat away the best food sources first, leaving only lower-quality food sources remaining. Also remember you CANNOT stockpile deer like in your example. Eventually you run out of food, or at least high-quality food, and reproductive success will rapidly decline (even without hunting). Most [U]healthy[/U] deer herds will double their population every 2 years. But as the herd explodes in size, eventually that population growth slows dramatically once the habitat resources begin to decline due to over-browsing. Eventually, a very overpopulated herd stops growing. Births equal deaths and the herd population stabilizes, albeit at an extremely low health level. [/QUOTE]
