 note = {In this paper, the author attempts to review studies on the forest limit. Comparing notion of the forest limit in various studies, we can find some confusion in the terminology and definition of the word. A difficulty of defining the forest limit due to existence of the ecotone affects this confusion. The forest limit is controlled not only by the present climatic conditions but also by the historical processes. Various informations on the climatic changes involve in the forest limit. In Japanese mountain area, the forest limit had been decided by the lower limit of Pinus pumila zone. For some similarities between the subalpine forests and Pinus pumila thickets, however, we can conclude the Japanese forest limit is not equivalent to the boundary between alpine and subalpine belts.},
