Liancourt Rocks
Liancourt Rocks was declared "Natural Monument #336" by South Korea in the 1990s. Some birds actually live on the islands, but most are just using them as a stopover to fly elsewhere.  The fork-tailed petrel, streaked shearwater, and black-tailed gulls live on the islands. The population of breeding birds counted on the rocks, however, has been declining in recent years.
