This study examines the relationship between these benefits and membership levels for a sample of 91 land trusts, while controlling for local demographic and area characteristics. Trusts that offer member-only access to property have higher membership, but most trusts do not provide such benefits. Membership increases with local population, but at a decreasing rate, consistent with the free-riding behavior found in other studies of collective action. The study finds the existence of scope effects with respect to the amount of protected acreage. (JEL Q15, H00)
