We hear all the time about the increase in wildfire control costs, which are unbudgeted, and the politicals are not keen to get saddled with a tax on their record, so budget cuts, or shifts. Also remember that the Reagan administration nearly doubled the miles of forest roads back then, the purpose of which was to extract some timber, do dome mining, etc. I would guess that road maintenance is one of the top budget items for both the BLM and the USFS, and a lot of those very roads are the ones that are getting trenched. The ones that aren't getting trenched are in a sad state down here in the Gifford Pinchot. The ones they paved cost even more to maintain, and were built with questionable engineering on unstable slopes in the first place. Reagan tried to shift the USFS to a model in which timber harvest paid the bills, but that kind of flies in the face of the original multiple use ideal the national forests were created to serve.
The worst thing I see down here is that they don't keep up ditches and culverts. Nothing will destroy a road faster than water. I think they should give up on grading more than twice a year to get ready for snow and smooth out the damage in the spring. The morons who fly down these roads at 40+ mph will washboard out a freshly graded road in two or three days, and I just don't think you can teach em'.
If we are going to have an outdoor playground for all Americans to enjoy, it is going to cost money, and the wildfire cost should be paid for by the folks who start the fires, cause climate change, whatever. (these fires are NOT the result of forest mismanagement... they are a result of extended dry periods with low humidity and abnormal wind plus name your spark)
As long as I have been alive, some of the trail work has been accomplished with volunteer labor. I wonder if today it is harder to find those willing to put some time in. A lot of the wilderness lakes down here are stocked by volunteers who bring the fish in in backpacks, and it's been that way as long as I can remember. Again I wonder if there are still (as many) people willing to do it.
