There's been extensive discussion recently about the fate of Mountain Biking trails in Jasper National Park. In particular, there have been calls to close most of the trails surrounding the townsite to mountain bikes. Most have cited the usual "Bikes to more damage than hikers" and "Bikes are worse for wildlife" lines.
However, I did some digging and it appears that the scientific jury is still out on this one. A few studies have found some mixed results, but most conclude by suggesting the more research is needed before conclusions can be drawn. I've added a list of references at the bottom of this post (just a list, as the actual articles are copyright material).
I did, however, find a review published by the New Zealand Department of Conservation that I think takes a solid, level-headed approach to the subject. It's worth a quick read if you have a few minutes. Essentially, it confirms most of what we already know. That is 1) that we don't know much about the environmental impacts of mountain bikes and 2) that the real issues here are more related to perception and social values than ecology.
Anyway, have a look and let me know what you think. If you know of any other research, I'd be keen to read that also.
