This paper investigates links between the strength and type of social networks and private forest conservation activity in rural Nepal. Using Nepal household survey data, this paper tests the effects of alternative social network indices on the number of trees planted on private land. Our findings show that social networks can have positive spillovers effects. However, this generalization requires careful qualification about the type of social network involved. While there has been considerable discussion about building and enhancing social networks, the policy implication is that not all networks are created equal when it comes to enhancing critical conservation activities.
