Tje dispersion and adaptation of the recently immograted plant, prickly lettuce (Lactuca serriola), were studied. The distribution of prickly lettuce was limited to south of the central districts of the Korean peninsula. The distrbution range is being diffused contimnuously by manual transportation. The 10 selected sites showed typical road side vegetation of an early successional stage; tje quadrats had 90% herbaceous cover, 5% shrub cover, and no tree cover. Dominant species were Kummerowia stipulacea, Ixeris chinensis, Ambrosia artemisiifolia, Lactuca indica, Toungia sonchifolia, Cephalonoplos segetum, Rubus parvifolius, Izeris polycdphala, Hemistepta lyrata, Cercis chinensis Artemisia capillaris. The investigated sites were divided into 4 patterns based on vegetation with high dissimilarity. The presence of mant patterns, despite high livels of differences, indicated that the characteristic prickly lettuce communities were not yet formed.
