Walk along some MTB routes that haven't been made sustainable with gravel or plastic mesh with your eyes open. Better still, join a bike park supporters' group and spend a few months doing track maintenance and it will become very clear.
I love MTBing, I like gnarly technical bush riding, I'd like to see as many tracks as possible open for MTBs, but I can't imagine what you're thinking to suggest that bikes don't do more damage than feet. Feet make separate isolated marks so it is very unusual for walkers to all step in exactly the same place; bikes make a continuous groove which becomes a line for subsequent riders to follow. That means that, even on flat tracks, bikes are going to wear a groove in a way that walkers wouldn't.
Once you get onto slopes the relative performance of bikes against walkers is even worse: going uphill, back wheels spin and make little gouges; descending, the way most youngsters and beginners ride is to go as fast as possible and lock up the back wheel around the corners. But even careful descenders are likely to get some slide.
These grooves and gouges can amount to a significant amount of track damage by themselves. On a surface that hasn't been designed for riding, they will also become runoff channels for rainwater, and this leads to serious erosion damage in a relatively short time.
I hope this gives you a starting point to rethink your perspective. I also hope you can convince the council to open up tracks for MTBing, even if that means user group has to be set up to fund preliminary upgrading of track surfaces. Just don't tell them to "prove that mountain bikes do more damage then walkers", or the project will never get off the ground.

Your thinking is stuck in the 80's - science has done much to demonstrate that cycling creates no more or less damage than walking. the arguments you use here have been used by walkers for years to 'demonstrate' how bikes do more damage than they do, they are wrong. Walking creates a very different sort of damage, spaced compaction on sloping terrain - and less lateral displacement than cycling - but still similar in overall damage and maintenance cost requirements. This research also demonstrates that motorbikes and horses have an impact similar to walkers and riders (this is rather more depandant on substrate and slope than the comparison of walkers to riders though).fatwombat wrote:Giantman wrote:proveto me that mountain bikes do more damage then walkers.
