“…In the middle to late 20th century, Korean pollen investigations were carried out in peat or organic-rich soil from coastal wetlands or lagoons (e.g., ., Jo, 1979;Oh, 1971;Park, 1990;Tsukada, 1977;Yi et al, 1996;Yoon, 1997). Subsequently, a number of palynological studies were performed due to increased peat layer recovery from excavations of inland wetland and archaeological sites (e.g., Chung & Lee, 2006;Kim et al, 2001;Seo & Yi, 2001;Yi et al, 2006Yi et al, , 2008a. Attempts were made to reconstruct the natural vegetation history in response to climate change from the peat and wetland samples and to intrepret human-induced changes based on agecontrolled pollen profiles, (agriculture and land-use in forests).…”
