Surveys of Korean flora have identified more than 3,000 species on the peninsula, of which more than 500 are endemic. The peninsula's floristic provinces are commonly divided between warm-temperate, temperate, and cold-temperate zones. The warm-temperate zone prevails over the southern coast and islands, including Jeju-do. It is largely typified by broad-leaved evergreens.
The temperate zone covers the great majority of the peninsula, away from the southern coast and high mountains. It is dominated by the Korean pine and various broad-leaved deciduous trees. Cold-temperate vegetation is found along the peninsula's northern fringe and in the high mountains, including the upper reaches of Hallasan on Jeju. Evergreens in this area include larch and juniper. Much of this vegetation is shared with Manchuria.
According to the World Wide Fund for Nature, the Korean Peninsula consists of several ecoregions. The Southern Korea evergreen forests occupy the southernmost portion of the peninsula, as well as the island of Jeju. The Central Korea deciduous forests occupy the more temperate central portion of the peninsula. The Manchurian mixed forests occupy the northern lowlands and low hills of the peninsula, and extend north into Manchuria as far as the Amur River on the Russia-China border. The Changbai Mountains mixed forests include the higher elevation mountain region along the North Korea-China border, where forests are dominated by conifers, with alpine meadows and rock slopes on the highest peaks.
