If you look at some of Ed Webster's historical photos, the tree cutting around cathedral is astounding . At least as a State park it's reasonable now.
The impact of climbing on the enviroment is pretty minimal..
There is people who bring other opinion: "Their must be an expert among us who can speak to what real impact that cleaning of cracks, scrubbing of lichens, and the disruption and annihilation of critters tiny and not so tiny has on New Hampshire's cliffs. As a climber who has done his share of un-earthing new routes, it has been my observation that if the routes do not get climbed it does not take long for mother nature to fill in the cracks and reestablish plants and critters. Most of the original equipment returns. The real question, however, is what rare and fragile plants and animals get annihilated and never come back and become local extirpated or made outright extinct? also, even things grow back, is it the original stuff?" (smartpig).
if we think at the peregrine falcon, at many trees like the one on recompense and pine tree eliminate, the trail at the bottom, the looking area at the top, the noise, the car on the road, bathroom, erosion, etc. Ecology is more the study of evolution of an area than just a picture of what you see one day....and money!
As you can see, bolt is not very important. But the evolution is. At the beginning, bolt was just to protect move that can be dangerous to do other wise, after, we place some bolt anchor to be able to rescue people, if we rescue people, we most place a couple of more bolt to avoid accident, as many people want to climb and just need and other bolt, why don't we bolt all the route except at obvious place where a noob can place a cam...and with time we will have a second rumney:
Rumney has become such a crowded mess I doubt there is much that can be done to keep the area in good shape. More people just bring more erosion and problems. Many people view Rumney as nothing more than a big outdoor gym IMO and care little about anchors or anything else other than beating the other guy to thier route. I was there last Saturday for the first time this year and it will likely be my last. What a ZOO!
