Every animal must live somewhere, but all animals cannot live everywhere. Each species of animal needs a particular environment in which to live and landowners must be aware of those things in that environment that wildlife need to survive and reproduce. Landowners and resource managers should be cautious when considering alterations to wildlife habitat; when you alter the habitat of one species, you enhance or affect the habitat of another. From a long term perspective, management practices do not destroy ecosystems; they only temporarily modify them and change the assemblage of species comprising the ecosystem.
