So، this research through analysis of collaboration network between state and formal public institutions in implementation of mechanical and biological watershed management projects and comparing them together tries to answer this question: Whether the extent of collaboration of formal public institutions with state institutions in implementation of mechanical and biological watershed management projects differ? The data was gathered through questionnaires were filled by asking from formal public institutions of Rural District of Berentin located in Hormozgan province and the experts and managers of Organization of Natural Resources and Watershed Management.

Also، the network connectivity and involvement of public and state institutions of these projects is more than the other one. So، because of the high social support of public institutions from biological watershed management projects in this Rural District، these projects could be the best، the most effective and the cheapest solution for soil erosion decrease in this Rural District and even in Hormozgan Province.
