Five vegetation stages were established on the basis of the composition of tree pollen assemblages and radiocarbon dating. The vegetation stages were as follows: superiority of the Castanea crenata forest (ca. 5300‒4400 cal BP), the Aesculus turbinata forest and the Castanea crenata forest (ca. 4200 cal BP), the Celtis-Aphananthe and Aesculus turbinata forest (ca. 3800‒3400 cal BP), expansion of the Castanea crenata forest (ca. 3300‒3200 cal BP), and deciduous broad-leaved forests such as Quercus subgen. Lepidobalanus, Carpinus-Ostrya, and Acer (ca. 3000‒2800 cal BP). The Castanea crenata forest was formed by the side of a river in the middle phase of the middle Jomon period, and it was actively occupied by the Jomon people. During the early to middle phase of the late Jomon period, it was estimated that the distribution of the river-side Castanea crenata forest was progressively decreased by use of timber, and afterwards, the Aesculus turbinata forest was expanded. At the side of the river, the distribution of Castanea crenata trees decreased in the late phase of the late Jomon period, but the Castanea crenata forest expanded again in the early phase of the final Jomon period. It was presumed that Cannabis sativa was cultivated in and around the site during the middle to late Jomon periods. Toxicodendron vernicifluum timbers have been excavated from the Shimoyakebe site at the early to middle phase of late Jomon period; however, it seems that male Toxicodendron vernicifluum trees were not distributed in this site at that time because of the absence of Toxicodendron vernicifluum pollen.},
