One would think it should be easy but I can tell you, as someone who deals with contractors, getting them to come back and do things is a giant pain. We had contractors walking away from retainage payments because they could go to the next job and make more money.
I dont deal with the environment side but I can tell you that one reason we like to contract out as much as possible is because it is far easier to deal with one company for the good and bad. In your case, it is probably far far easier to contract logging company to cut the trees than it would be to allow every Tom, Dick and/or Harry to go cut the trees. Simply from an enforcement and monitoring stand point. With contracts, you can set the rules and if the rules arent followed, its one person to point the finger at. If you open it up, even with rules, who do you blame if they arent followed?
I would be curious to know why they pile and burn it versus allowing a logging company to sell it. Just to clarify, are they burning everything cut or are they just piling and burning slash?
Not saying its right, not saying its the way that it should be done but sometimes, and more times than not, people are their own worst enemies.
