Landscape-scale collaboration has become an important pathway to manage and steward public lands and natural resources in the United States. To understand the impact of formalized, collaborative efforts, a new partnership called One Tam (, based in California's Marin County, was studied in its first four years. Findings from this research include a collection of interdependent, scalable impacts that are presented as the Partnership Impact Model -- highlighting three impact classifications: foundational, operational, and outcome. This emergent model has practical implications for collaboratives and funders struggling to identify ways to understand, describe, and optimize partnership impact.
