The Korea Maritime Environment Corporation is conducting a comprehensive survey of the national marine ecosystem under the commission of the Ministry of Oceans and Fisheries (MOF) to ensure continuous use of the ocean, preserve and manage the marine ecosystem. The survey has set major peaks to investigate changes in the marine ecosystem around the Korean Peninsula. However as the peak has been set around the coast, it is necessary to expand the scope of investigation to encompass offshore areas. Meanwhile, the Aids to Navigation Division of the MOF supports a comprehensive national marine ecosystem survey providing photographs of fouling organisms during the Aids to Navigation lifting inspection, however, the photographs are provided only in consultation with the Korea Maritime Environment Corporation. Therefore, a study was conducted to generate information on fouling organisms using deep learning-based image processing algorithms by the lifting Aids to Navigation and dorsal buoys so that Aids to Navigation could be used as the major component of a comprehensive national marine ecosystem. If the Aids to Navigation are used as the peak of the survey, they could serve as fundamental data to enhance their own value as well as analyze abnormal marine conditions and ecosystem changes in Korea.

This survey was conducted from May 2017 to August 2018 as part of the National Marine Ecosystem Surveys sponsored by MOF (Ministry of Oceans and Fisheries) and KOEM (Korea Marine Environment Management Corporation). The survey was conducted at 157 stations including intertidal zones, coastal sand dunes and beaches. A total of 72 species of halophytes were identified and the total vegetated area was $1,813,546m^2$ in coastal waters of Korea. In the west coast region, Suaeda japonica was the dominant species, Phragmites communis in the southern coast, and Carex kobomugi in the east coast. Phragmites communis was the most dominant with $1,136,643m^2$ (62.7%) in the whole surveyed area. The top 11 dominant plants are Phragmites communis, Suaeda japonica, Suaeda maritima, Zoysia sinica, Carex kobomugi, Elymus mollis, Suaeda malacosperma, Phacelurus latifolius, Triglochin maritimum, Carex pumila and Carex scabrifolia, and Phragmites communis and Suaeda japonica accounted for 75.9% of the total vegetated area. The distribution of halophyte on the coast of Korea was determined by the habitat types rather than the climate ranges, and there was a difference in the species diversity and habitat range of the halophyte depending on the habitat diversities within the same area.

This study aimed at suggesting management policy directions for the uninhabited islands of Korea which are national land resources with economic potential for tourism and development and strategic value for boundary delineation of territorial waters and exclusive economic zone as well as their unique ecological status. Review of existing management arrangements related to the uninhabited islands revealed six management issues to be addressed: insufficient data and their low reliability, lack of management policy directions, increase in ecosystem deterioration and perturbation by human activities, lack of policy measures for meeting utilization and development demands, weak management base with insufficient personnel and budget, and legal measures not taking Into account their unique ecological and socioeconomic characteristics. The management policy directions to improve the management of the uninhabited islands of Korea include management directions and strategies, and suggestions for legal improvement. Considering the unique ecological value of the uninhabited islands, management directions suggested are anti-degradation in which current and future demands for their utilization and development do not degrade the ecological potential of the uninhabited islands and integration in which land and sea areas are managed as an integrated management unit. Four strategies proposed to follow the management directions are enhancement of the knowledge base through a comprehensive survey, development and legislation of guidelines for the rational management of utilization and development demands, establishment of the comprehensive island debris collection and disposal system, and enhancement of management capacity. Legal improvement for the effective implementation of the management policy directions should include comprehensive uninhabited islands survey, legal utilization restraints and management guidelines based on classification of the islands, management boundary, and improvement of regulations on designated islands.
