Site Outline

Tomakomai Experimental Forest (TOEF) is situated in the southwestern part of Hokkaido at the northern part of Tomakomai city (42o43′ N, 141o36′ E). It has 2,715ha area, approximately 1/20 part of whole Tomakomai city.
TOEF consists of mature deciduous broad-leaved forests (dominated by Quercus crispula, Acer mono, Tilia japonica), secondary deciduous broad-leaved forest, and manmade coniferous forest, either of which covers about 1/3 of the whole area. The some of secondary forests formed after unsuccessful afforestation, although some of them formed after clear-cutting or wind disturbance. The grounds are covered mainly with 5-10cm depth immature soil that originated from volcanic gravels, which largely affect the forest vegetation at this area.
