Restoration of seabird habitats in Chilbaldo island
Proportion of the area of the contribution comprising Key Biodiversity Areas: 0%
Korea National Park Service (KNPS) has successfully restored the seabird breeding grounds of Chilbaldo Island in the Dadohaehaesang National Park, which is a stopover site for over 50 species of rare seabirds. The lighthouse on Chilbaldo island was operated until the 1990’s, which allowed people and alien species such as Artemisia indica, Brassica juncea, and Miscanthus sinensis to the island. They have gradually prospered until they impeded the growth of native species, which prevent birds from making nests for breeding. In particular, Achyranthes bidentata is a perennial plant that produces hook-shaped seeds in September and October. The wings of seabirds get entangled in them. It makes birds unable to flip their wings, driving them to death from exhaustion. Since 2014, KNPS has been restoring the habitats by intensively removing alien species and planting the native Carex boottiana Hook. & Arn. to allow seabirds to make nests stably between bedrock and underplant roots.
Potential conservation benefits in saving biodiversity
Potential reduction of species extinction risk resulting from threat abatement actions
Absolute value (STAR)
1% of the total biodiversity conservation potential of Republic of Korea is covered by this project.
0.3% of Asia's biodiversity conservation potential is from Republic of Korea.
25.9% of global biodiversity conservation potential is from Asia.
The chart below represents the relative disaggregation of the selected contribution's total potential opportunity for reducing global species extinction risk through taking actions to abate different threats to species within its boundaries. The percentages refer to the amount of the total opportunity that could potentially be achieved through abating that particular threat.
