In the spring, deer tend to make forbs around 66 percent of their diets. To a deer, home is the forest. Without this variation, natural selection would not be possible. Yet all climate change mitigation schemes rely on the existence of healthy natural areas. This is an example of the type of mistakenly human-centered planning that continues to be made in many fields, including climate change mitigation, resiliency planning, urban planning, agriculture and so on.

Doctoral dissertation, Harvard University, Graduate School of Arts & Sciences. Culling may be necessary in some circumstances if there is overpopulation of deer. If this happens for long enough, tipping points are reached, leading to a strange, simplified state that cannot recover naturally, even assuming the deer are somehow removed. Deer don't shift their breeding to match earlier springs, a maladaptive response that results in fewer offspring raised. Of course, there must also be a substantial water source as well.

The latter is an important way to gauge ecosystem decline when browse-sensitive species have disappeared.
