Landowner's Guide: Edges and Fragments
Dave, most species don't need the seclusion that you talk about; they adapt and often thrive
becauseof our activity.
Habitat Planning, Working With Neighbors:
"As more and more land is converted to houses, highways, and shopping centers, wildlife habitats become fragmented and isolated. This fragmentation makes it difficult for wildlife to find the right combination of habitat components necessary for their survival."
Species Management, Whitetail Deer:
"White-tailed deer live in every county in Michigan and use many different habitats across the state. Their ability to use a variety of habitats was one of the factors that allowed the deer herd to grow from a half million animals in 1972 to nearly two million in 1989. To outdoor enthusiasts who watch or hunt deer, this is exciting. However, to others, deer are considered to be a management problem. For instance, many areas of the state are overpopulated with white-tailed deer and for some farmers, fruit growers, and rural landowners, high numbers of white-tails pose an economic problem. They may also have a tremendous negative impact on our plant communities. Therefore, as deer populations increase, there is an inevitable result of habitat deterioration, lowered deer production and health, and frequent deer die-off. Too many deer also make for unsafe driving conditions. Thus, consider these negative impacts before deciding to manage for deer. Remember that your decisions will affect not only yourself, but also your neighbors."
Edge Management:
"Before European settlement, Michigan's historical ecosystems included edges and fragments. However, today there is a large amount of habitat fragmentation, especially in the Lower Peninsula, due to the addition of nearly 10 million people to the state. As a result of habitat fragmentation, many edge-loving species have become abundant, while edge-sensitive species have reduced in numbers."
Your conclusion regarding seclusion isn't what I take away from the info.
With regards to edge habitat, the gist seems to be there was once less of it, now there is more due to fragmentation, if there is to be more by necessity of human use, it should be well-managed to be as beneficial as possible. In other words, make the best of the remaining degraded habitat. That is an admirable goal. I bet a lot of us do that.
Naturally, some species will benefit by changing the landscape, and some will not. But that isn't the same as just setting aside areas and letting them be wild. Those wild areas will revert to as near a truly natural species and plant life condition as possible. Even then, the plant and animal make-up is going to be continually changing due to natural causes, and there really is no place on the globe that human influences have zero impact.
Woolly Adelgid on hemlock is an example. Milder winters are thought to be allowing it to spread inland and northward. As it does so, the number of hemlocks will decrease, and whatever finds a use for hemlock will also be under stress. Some other plant will take over the hemlock niche, often found adjacent to wet areas in this area. Something will benefit from that next plant, maybe. We could have large tracts of wild forest that are still not totally immune from external changes.
There is a natural balance to relatively undisturbed nature. It is absurd to think that deer hunters know how many deer or deer predators there are
supposed to be. They know they would like to have plenty of deer to hunt, but that's a different question that leads down a much different solution path. Managing wildlife for the benefit of one or two species is really farming or ranching.
