Respect ethical obligations to the non-human world. Forests are increasinglyvalued for more than their utilitariancontribution to human health and wel-

fare. Environmental philosophers havebeen identifying and defending the in-trinsic values in forest ecosystems, andopinion polls suggest increasing publicsupport for the rights and integrity ofwild forests. Although such values arehard to define and quantify, scientists,managers, and the public are using con-

Increasing the skills and expertise Community-Based Restorationof volunteer restorationists might there-fore be a goal for those who managevolunteer-driven restoration programs(see "The Volunteer Stewardship Net-work"). Informal peer teaching in thefield is a critical component of knowl-edge and a valued aspect of the volun-teer experience (Ross 1994), but formaltraining and certification programs canalso help equip volunteers with the ex-pertise and credentials needed to do thejob right. Combined with the appropri-ate level of professional supervision, thiseducational mix can create a corps ofcitizen stewards who remain motivated

and are trusted by the broader public(Harris 1997).

Create informed constituencies fornatural areas management. Restorationprograms that are volunteer-driven adda distinct value to ecological restora-tion that does not accrue to programsrun by in-house staff or outside con-tractors. By engaging local citizens inlong-term, hands-on efforts, managersdevelop an informed constituency forbroader land management concerns.As a form of collaborative manage-ment, volunteer-based restoration ef-forts have virtues that mirror those ex-

pressed in the ideals of participatorydemocracy--in this case, creating acommunity of citizens who are activelyinvolved in learning about, participat-ing in, and taking responsibility for theconsequences of land management de-cisions.
