In this article, local institutions for forest conservation and management are analysed. The discussion is based on data from 37 villages and 180 households randomly sampled from a protected area in Rajasthan, India. Local management institutions are described, factors affecting inter-village differences in management institutions and collective action are analysed in a logit model, and the impact of institutions and other variables on common resource dependency and forest outcomes is tested using instrumental variable regression. Village population size has a positive effect and prior institutional experience a negative effect on the probability of collective action. It is concluded that efforts at improving forest management should not be confined to the poorest farmers. Large landowners are heavily involved in degrading use practises, especially when resources have good market potential. Local management institutions play a positive role in the area, but their impact appears insufficient to safeguard forests and commons from continued degradation. Conservation policies should target win–win options through interventions aimed at improving technologies for private and common lands as well as institutional changes.
