There are many kinds of inhabited environments such as tidal flats (8 places), uninhabited islands (23 places) in the Namhae·Sacheon district of Hallyeohaesang National Park. Especially the Leeraksa tidal flat is excellent habitats that 5 endangered species inhabit.

However, as the sedimentary environment of the habitats has been simplified through coastal development and road construction, habitats for endangered species have been decreasing. The Korean National Park Services(KNPS) designated National Park Special Protection Area for the first time in Korea to protect the habitats for Milky Fidder Crab(Uca lactea) which is particularly vulnerable to environmental change.

The KNPS monitored inhabited environments as well as changes in the habitats and made seawater flow smoothly by removing the artificial structure which had been neglected for 30 years.

Analyzing sediments for three years, the KNPS realized the need for the Sand Capture Machine to prevent sand runoff. The KNPS benchmarked "Lahnung", the reclamation method in the German tidal flat and installed the Sand Capture Machine, which is on test operation.
