    Site NameTeshio CC-LaG experiment site
    AsiaFlux Site CodeTSE
    LocationTeshio Experimental Forest, Toikanbetsu, Horonobe, Hokkaido, Japan
    Position45deg 03' N, 142deg 06' E
    Elevation Elevation: ca.70m, a.s.l.
    Slope < 8 deg
    Terrain Type Flat Terrace
    Area 13.7 ha (Clear-cutting area), however, same vegetation type extends ca. >1 km for each direction before clear-cutting
    Fetch >1 km (mixed forest), 200-500 m (after clear-cutting)
    Climate Cool-temperate
    Mean annual air temperature 5.7degC
    Mean annual precipitation 1000mm
    Vegetation Type Conifer-Hardwood mixed forest until January, 2003, Young larch plantation from late October 2003 (ca. 30000 saplings (ca. 2500 saplings ha-1; 0.04 tC ha-1))
    See Takagi et al.(2009a)
    Dominant Species (Overstory) Quercus crispula, Betula ermanii, Betula platyphylla var. japonica, Abies sachalinensis, Picea jezoensis (mixed forest), hybrid (Larix gmelinii × L. kaempferi) larch (young larch plantation)
    Dominant Species (Understory) Sasa senanensis and Sasa kurilensis
    Canopy height 18-25 m (mixed forest), 1-2.5 m (larch plantation in 2006)
    Age Large trees in the clear-cutting area were more than 200-years old(Tsuji et al., 2006). In Autumn 2003, 2 year-old larch saplings were planted.
    LAI 3 and 4-4.5 in a full-growing period for canopy and Sasa layer, respectively in the mixed forest, Larch LAI in the stripe-cut row is ca. max 1.3 in 2005 and Sasa in the remained row is increasing (ca. max 5.7 in 2005) after the clear-cutting (measured by LAI-2000, LI-COR)
    Soil type The bedrock was Cretaceous sedimentary rock. The dominant soil was a Gleyic Cambisol (FAO 1988) with about 10 cm of O horizon, with a mor humus type, 20 cm of A horizon, and 30 cm of B horizon
