Trail-Building: Habitat Destruction by a Different Name

Scientists are generally honest, in what they say – but not in what they choose to study. Despite a diligent search in one of the world's best libraries (the University of California, Berkeley), I wasn't able to find a single book or article on the harm done by trail-building. I notice that whenever I see a picture of a trail, I think "Oh, a trail – so what?" It takes an effort of will to think about the wildlife habitat that was destroyed in order to build the trail. And the habitat destruction isn't restricted to the trail bed. As Ed Grumbine pointed out in Ghost Bears, a grizzly can hear a human from a mile away, and smell one from five miles away. And grizzlies are probably not unique in that. In other words, animals within five miles of a trail are inhibited from full use of their habitat. That is habitat destruction! If there were no trails, we would be confronted by our own destructiveness every time we entered a park. It is only because the habitat has already been destroyed for us, that we can pretend that we are doing no harm. That leaves only one option compatible with wildlife conservation: minimizing the construction, extent, and use of trails.
