Mid-Holocene Vegetation and Environments on the Northeastern Coast of the Korean Peninsula
The pollen and spores from sediments of the core recovered from the shelf zone of the East Korea Bay, Eastern Sea (Sea of Japan) were studied. The vegetation of the northeastern coast of the Korean Peninsula was reconstructed based on pollen records. The most favorable conditions existed in mid-Holocene for the development of oak broadleaved forests. Fossil pollen grains of Quercus L. were studied with application of scanning electron microscope. Six types of fossil pollen grains were revealed: four types of them were assigned to deciduous oaks and two types to evergreen oaks. The deciduous oaks Q. dentata, Q. mongolica, and Q. serrata took significant part in vegetative associations of coast in mid-Holocene time.
