This checklist presents considerations and best practices for carrying out all-lands projects that leverage partners’ diverse skills and capacities to accomplish more than the sum of their parts. Across the West, practitioners working on sustainable land management and restoration have increasingly focused on efforts that cross public, private, and tribal boundaries. Working across multiple land ownerships creates efficiencies, helps leverage resources, and better addresses the interconnected nature of today’s ecological and economic challenges. While this type of “all-lands” work has gained broad support and interest, it is also complex, involving multiple partners, different land ownerships, diverse objectives and priorities, and many funding sources.
