This one is just for our forest...the original plan was adopted in 1988 and, believe it or not, these management plans are revised...every 30-years or so.
There are other forest management plans around the western states currently in various stages of revision.
The original plan for our forest is a joke...the 10988 plan called for increasing grazing permits, (currently about 50% less than recommended) increasing road construction for logging access...a total joke...there is no, none, zero logging on our forest and there has not been a mile of road constructed in the past 10-years that I know of.
Thirty years ago there were 5-active sawmills within about 25-miles of our town...the last mill closed down in the early 1990’s.
The entire concept is just an appeasement process to convince everyone that the USFS is actively managing the forest. That is obviously a farce.
