一个花粉记录（CA。21，800至9，900 cal. yr BP）的一个玛珥揭示了韩国济州岛上最后一次冰消期植被和气候变化的详细历史。在LGM期间，21，800到14，400 cal. yr BP）卤虫占主导地位的草原，在寒冷干燥的条件下发展出冷温带落叶阔叶林。从约14，400 ~ 11，800 cal. yr BP，温带落叶阔叶林的扩张和草原植被的退缩表明植被从冰期向间冰期的过渡。在约1000年以后，暖温带常绿落叶阔叶林的出现，林下有蕨类植物。11，800 cal. yr BP表明温暖潮湿的条件，类似于济州岛的现代气候。蒿属和水龙骨科的显著波动表明在晚更新世至全新世过渡期湿度的变化。花粉记录反映了植被对末次冰消期气候变暖的响应，也反映了海平面上升对地理变化的影响。
A pollen record (ca. 21,800 to 9,900 cal. yr BP) from a maar reveals a detailed history of vegetation and climate changes during the last deglaciation on Jeju Island, South Korea. During the LGM (ca. 21,800 to 14,400 cal. yr BP) Artemisia-dominated grassland with patches of cool temperate deciduous broadleaved forest developed under cold dry conditions. From ca. 14,400 to 11,800 cal. yr BP a vegetation transition from glacial type to interglacial is indicated by the expansion of temperate deciduous broadleaved forest and the retreat of grassland vegetation. The appearance of warm temperate evergreen and deciduous broadleaved forests with a fern understory after ca. 11,800 cal. yr BP suggests warm humid conditions, similar to modern climate of Jeju Island. Prominent fluctuations in Artemisia and Polypodiaceae indicate variability in humidity during the Late Pleistocene to Holocene transition. The pollen record reflects a vegetation response not only to the last deglacial warming but also to the influence of geographical change resulted from sea-level rise.
