The work

What they do

Professional society for wilderness managers and stewards from all four federal wilderness-managing agencies. Training, standards, and knowledge sharing.

Every year they sign one sentence and file it with the federal government: “THE MISSION OF THE SOCIETY FOR WILDERNESS STEWARDSHIP IS TO ADVANCE THE PROFESSION OF WILDERNESS STEWARDSHIP TO ENSURE THE LIFE-SUSTAINING BENEFITS OF WILDERNESS. AS A MEMBER-BASED ORGANIZATION, WE SEEK TO INCLUDE A DIVERSITY OF PEOPLE DEDICATED TO WILDERNESS STEWARDSHIP, INCLUDING MANAGERS, SCIENTISTS, EDUCATORS, VOLUNTEERS AND NON-GOVERNMENT CONSERVATION STAFF MEMBERS.”

That ratio is a good sign, not a scorecard. Plenty of great groups run leaner and lumpier. What matters is the extremes, and Society for Wilderness Stewardship is nowhere near one.

Honesty note: leadership comes from each year’s federal filing, so it can run a year behind. Orgs that claim their page can update it same-day. Work at SWS? Claim this page.

Those 10 volunteers are people who decided this ground was theirs to defend. If SWS is fighting for your place too, the matchmaker will find your way in.
