South Korea
South Korea occupies the southern half of the Korean Peninsula and is predominantly mountainous, with forested ridges covering much of the interior. Agricultural plains and most major cities are concentrated in the west and south, while the eastern Taebaek Mountains descend steeply towards the Sea of Japan. The country's long coastline includes extensive tidal flats, estuaries and thousands of islands, particularly along the Yellow Sea. South Korea has a temperate monsoon climate with hot, humid summers and cold, relatively dry winters. Jeju Island, formed by volcanic activity around Hallasan, adds a milder southern environment with distinctive forests, lava landscapes and coastal habitats.
Overview
South Korea is particularly important for East Asian migration and wintering waterbirds. The Yellow Sea coast lies on the East Asian–Australasian Flyway, with tidal flats supporting large concentrations of shorebirds, including Spoon-billed Sandpiper and Far Eastern Curlew. Cheorwon and other northern wetlands are famous for wintering Red-crowned and White-naped Cranes, while coastal areas attract Steller's Sea Eagle and numerous geese and ducks. Forests support Fairy Pitta, Yellow-rumped Flycatcher and various woodpeckers, and offshore islands can be excellent migration watchpoints. South Korea's extensive transport network makes many sites relatively easy to reach independently, although some productive areas near the Demilitarized Zone (DMZ) have controlled or restricted access. The combination of major migration sites, cranes and excellent infrastructure makes the country especially rewarding during migration and winter.
