Hi Jim,
you could try going onto the FC website and finding out who your 'local' forester is or who is responsible for maintaining the forestry in your area and speak to them direct, they may be more sympathetic than speaking to the FC directly.
Also, do you know if the fallen trees etc are a result of thinnings or windblow? If its thinnings then they should have removed what they cut, if its windblow then they might be planning to clear it up as part of their planned maintenance but who knows when?
Short term solution is build a sink hole
hope thats of use to you, how far north are you?
