The present study was proposed to answer the problem of mangrove forest destruction through various policies of the East Kalimantan Regional government by using the literature study method followed up through Focus group discussion. As a result of this research, the implementation of policies carried out by the East Kalimantan Provincial Government can now be said to be successful, although there are still indicators that need to be improved, such as in the resource variable. Moreover, it was found that there were still problems that occurred with the management of the Mangrove Forest area in the previous government. There are recommendations from the results of this research to conduct a joint evaluation with the Central Government regarding the policy of private sector activity programmes, and there must be supervision after planting. Provisions in sectoral laws related to natural resources, apart from those that specifically regulate environmental protection as in Law 32/2009, are regulated in various forms.
