He got banned once...and looks to be cruising for another.
As to the question of allowing chainsaws to be used given the current conditions? I think its a good idea.
I've spent extensive time in beetle killed and areas where fire went through in many wilderness areas around the interior west, its a nightmare to clear trail in some of those areas. As hank4elk pointed out, the funding cuts that the FS has taken over the years, makes it about impossible to clear all the trails. In particular areas like the Frank Church, Selway/Bitterroot, and others. Not sure how many people have used a cross-cut but its a lot of work, and time consuming. Its one thing to use a cross cut when you're cutting 8-10 trees a mile, its another when you're cutting 50-100 or more per mile. Even if the FS had the funding to hire the massive crews it would take, there's still limitations on when you can access many of the trails. High water, snow, and high elevation limits the window you have to complete the work.
As to the FS being lazy and contracting work out, not true at all. I have worked with and around trail crews my entire career. They aren't lazy and for prairiehunter to make such a statement only further illustrates his lack of knowledge and contempt for anyone that works for the Government. Its misrepresentation and axe grinding, nothing more. Trail crews are not lazy and IME, we've lost some very good employees and crews due to budget cuts. That's unfortunate. Finally, many times the only option available is to contract the work as funding is often uncertain, many times "soft" money. It would be wonderful if we could get back to having adequate, annual, funding and fill permanent seasonal trail crew positions.
I just think its time to use chainsaws to get caught back up with trail maintenance, either that or trails are going to have to start being abandoned. Management takes money, something Congress should understand, but seems to forget.
