Repair and maintain ALL primary and secondary FS and NPS roads that provide access to existing trails a/o, say, 1990. The White Chuck, West Side, Ipsut, Middle Fork, Suiattle, Steheiken, Dosewallips all come to mind. Where necessary to maintain access, relocate road beds to higher ground despite any wilderness boundary issues. The closing of capillary roads that lead to nowhere seems logical.
Only where real, quantifiable, unmanageable, and irreversible environmental damage can be demonstrated. Social considerations should be rare or non existent. (ie: Limits in the Enchantments; yes. Limits on St Helens; no.)
It already is making access more difficult for working individuals and families. It is concentrating use into fewer and fewer areas. It will eventually erode the user base and create apathy for the very lands being protected. It would mean that I cannot show my future grandchildren some of the great places I once enjoyed on the weekends. It would mean they won't grow up caring.
I hope your project is a sincere effort at balance. Is this work related to a master's thesis? If not, have you formulated a thesis statement for this project/paper? Quid pro quo?
