The age of the Kisohirasawa Peat Bed (36°N. Lat., 930m. above sea level) is determined to be the latest Pleistocene by radiocarbon dating. The results of pollen analysis together with the analyses of some plant remains of the bed are summarized as follows; (1) Subalpine conifer forests composed mainly of such genera as Picea, Abies, Tsuga and Pinus (Haploxylon) were dominant in the age. The montane deciduous broad-leaved trees such as Fagus were scarcely mixed in those forests. (2) Pollen grains of Abies consisted mainly of Abies veitchii LINDL. increase to the upper part of the peat bed. On the other hand, Pinus, that is composed mainly of Pinus parviflora SIEB. et ZUCC., decreases, and has thriven today both in the upper part of the montane zone and the lower part of subalpine zone. (3) The vegetation zone of Kiso Valley was lowered by about 1,000m in the early stage of the formation of the bed and was further lowered in the later stage.
