Conclusion
In conclusion remote sensing appears to be a significant tool for assessment and monitoring of coastal zone resources, especially mangrove forest. In addition, planning and management of forest land use is easily and effectively conducted using GIS. However, the integration of remote sensing and GIS for the development of mangrove forest management plans by natural resource managers and planners is necessary.
