Representation is a hallmark of democratic governance. Widely studied within traditional modes of governance, representation is less studied in alternative governance settings, such as collaborative governance arrangements. Collaborative governance arrangements are specifically designed to encourage inclusion and participation among a diverse array of stakeholders in some part of the policy process. Our research contrasts different forms of representation observed in a collaborative governance arrangement and identifies factors contributing to observed patterns in representation therein. We analyze descriptive representation (i.e., "representation in form") or substantive representation (i.e., "representation in practice") and look for inconsistencies between them. Our case study is a regional food policy council located in the Western United States. Among our findings is that discrepancies between descriptive and substantive representation can be explained by shared goals, local norms, organizational structure, and heterogeneity in member capacity. We conclude our article with a discussion of the theoretical and practical implications of this research.
