Three pollen diagrams of Komado-Ohyachi Moor in Fukushima Prefecture were compared. Data for the same period (from the climatic optimum in the Holocene to the present) were available from the three sites, which indicated that Fagus crenata forest was predominant over the whole Komado area, and at the same time one site (K12) was dominated by a Quercus mongolica var. grosseserrata stand and the other (JIMBO and SHIODA, 1980) was dominated by a Pinus parviflora var. pentaphylla stand. The former was referred to as“regional”vegetation and the latter two as“local”vegetations. Pollen analysis showed that Site K12 began as a community dominated by Cyperaceae in the latest Pleistocene and changed into a Moliniopsis japonica-Sphagnum community, a Fraxinus mandshurica var. japonica forest, a Osmundastrum cinnamomeum var. fokiense community, a Ilex crenata scrub, a Moliniopsis japonica-Osmundastrum cinnamomeum var. fokiense community and a Moliniopsis japonica-Cyperaceae community, in that order.
