Various surveys and studies on the natural environment are being carried out in order to formulate scientific and effective natural environment conservation policies. A national ecosystem survey, detailed investigations of outstanding ecosystems, and national distribution studies on endangered wildlife are currently in progress.

The national ecosystem survey is a comprehensive study on natural environments throughout the country consisting of investigations in the nine fields of topography, vegetation, flora, benthic macro-invertebrates, insects, fish, amphibians and reptiles, birds, and mammals. The first survey was conducted in 1986 and the fourth survey is taking place from 2014 to 2018.

Detailed investigations of outstanding ecosystems involve close examinations by ecosystem characteristics and regions. The National Institute of Ecology is working on detailed investigations of coastal dunes and estuary ecosystems, a natural environment survey on uninhabited islands, detailed investigations of regions with outstanding ecosystems and landscapes, and an ecosystem investigation in the DMZ.

National distribution studies on endangered wildlife are carried out by the National Institute of Biological Resources with the aim of preparing suitable conservation and restoration measures by identifying ecological information on 246 species that have been designated as endangered wildlife.

An investigation on long-term ecological changes has been in progress since 2003. This project has been making mid- and long-term observations on changes in natural ecosystems according to climate change and environmental pollution.

The comprehensive natural environment GIS-DB project is being carried out to build a database of current vegetation maps, topographic maps, and fauna and flora distribution maps obtained from the national ecosystem survey and information on key species identified in the detailed ecosystem investigations. The GIS-DB has been used to produce an ecological map that classifies the entire national territory according to ecological value, and this map has been made available through the Environmental and Geospatial Information Service ( The map is also referred to during environmental impact assessments.
