Why manage deer? - Lake County Forest Preserves

But in some of our highest-quality preserves, deer numbers are so high that their populations are not in balance with the habitat. These l ...

Habitat conservation
Habitat conservation is a land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
