Pollen records indicate that montane alpine conifers or sub-alpine conifer-deciduous broadleaved forests were alternately prevailed in the Korean Peninsula (KP) under the cold climate conditions during the late Pleistocene. Meanwhile, during the Holocene, vegetation dynamics response to climate changes can be well reconstructed from ca. 7,000 to 2,000 yr BP in Korea, because Korean interior wetlands are known to have formed about 7,000 yr BP. And also the topmost layer (encompassing 2,000 yrs) of the wetland sequences are lost or disturbed due to human activity such as agricultural cultivation or industrial purpose. Fortunately, pollen records from Lake Youngrang and Lake Hyang which are distribute along the central eastern KP reflect that during the early Holocene the vegetation covers were different between eastern and western sides of the KP, owing to differences in geomorphology and oceanic influenced humidity. These characteristics of the vegetation were lasted until mid-Holocene. Afterward, since 2,000yr BP the vegetation over the KP was dominated by pine tree, pinus together with common cultivation plants such as rice (Gramineae) and sage (Artemsia), and the first appearance of buckwheat (Fagopyrum). The changed vegetation covers are interpreted to have been influenced by cool climate and human impact. The matter facing the palynologist for vegeta-tional and climatic interpretation of last 2,000 yrs is to firstly get human-disturbance free wetland site and/or lacustrine sediments bearing last 2,000 yrs natural history in the KP. It is strongly required to make dataset of previous pollen records and then get high-resolution vegetation history and climate changes. Detailed age-controlled pollen records in association with multi-proxies are also needed in order to level-up advanced pollen study in Korea. Finally pollen profile should provide both relative climate conditions and absolute temperature degree in future.
