I would suggest you look at the forests. It is a real problem when looking at water sheds and fire protection and wild life habitat. It can be handled but only with the right chemicals.............that work.
Most of the Ash trees are gone due to the Emerald Ash Borer.
Forest fire will cause lodgepole seeds to sprout and renew the forest. Fire opens the cones to release the seeds.
The dead trees will burn. The pine beetle will die off to barely sustainable numbers, the forest will restart and rinse and repeat.
There are a lot of structures in the way though. But if have driven through Grand County Colorado, it is a forgone conclusion, thousands of acres are going to burn. If they started logging like hell it might help, but the housing slump says that won't happen.
