At its heart, conservation is about people - people with strong outdoor connections that steward and protect our landscapes, and grow a community of advocates for our wild places. The people that power conservation at The Mountaineers aren’t just our staff, they’re members and volunteers driven to preserve the outdoor experience for future generations.

The Mountaineers Conservation & Advocacy Committee (C&A Committee) is a standing committee of the Board of Directors tasked with advising the staff on conservation policy issues of potential importance to our members and stakeholders. The committee provides expertise and guidance to advance the organization’s conservation and advocacy work. Working directly with the Conservation & Advocacy Director and the CEO, the committee also supports the organization’s efforts to influence public policy and land management to protect public lands and the life-changing outdoor experiences they provide.

The committee is made up of The Mountaineers Board and Advisory Council members, as well as other members and individuals from outside the organization with deep expertise in conservation policy, communications, advocacy, and law, as well as a passion for protecting the Northwest’s special landscapes and the outdoor experiences they provide.

The C&A Committee is supported by The Mountaineers Conservation & Advocacy Director Betsy Robblee, Advocacy and Engagement Manager Conor Marshall, and CEO Tom Vogl. Braided River’s Executive Director Helen Cherullo and Conservation Impact Manager Erika Lundahl also bring valuable perspectives from their work inspiring conservation action through compelling narratives and visuals.

Making New Initiatives a Reality

Recent Conservation & Advocacy Committee work has focused on supporting several of our new initiatives, including: climate strategy, The Mountaineers land acknowledgment statement, and new opportunities for member engagement. Committee members' perspectives have been invaluable during our ongoing process to create a formal land acknowledgment statement for the organization and build resources to educate Mountaineers about ways we can respect and acknowledge the places we recreate as native lands.

The Committee also helped make our recent Conservation & Advocacy Town Hall an overwhelming success. This first-ever event provided a great opportunity for our conservation-minded members to learn about and provide feedback on our conservation and advocacy mission, strategy, and work. Staff are already working to implement some of the feedback we received from the event.

With the climate crisis impacting our public lands and communities in so many ways, the committee strives to shape our climate strategy so that we may effectively address the climate crisis as an increasing priority in our advocacy and other initiatives.
