Site Description
A 4.71-ha site in a beech-dominated landscape, with montane creek stand (2.48 ha) as well as adjacent terrace stand (1.08 ha) and steep slope connecting between them. Deciduous species-mixed stand, without evidence for logging, under temperate climate with heavy snow (max. depth: 1.8 m) in winter. Characterized by canopy breakage and fluvial transport of sedimentation, as well as bumpy ground surface with a mixture of boulders and deep soils. As a result, a diverse array of tree species coexist, with rich ground layer vegetation, in the riparian stand, whereas beech is the dominant species in the terrace stand. Intensive monitoring for seedfall and tree community dynamics since 1990's.

General Characteristics, Purpose, History
Site Status
existing
Year Established
1988
Purpose
To quantify disturbance regime; to describe life history of major tree species (ca. 10 spp.) with reference to riparian disturbance characteristics; to examine major ecological theories in community ecology; to document annual patterns of tree growth, seed masting, and other parameters in community dynamics; to extract effect of climate change and disturbances on the community dynamics, especially for tree recruitment and growth and seed masting.
History
Started as a 0.5-ha plot in 1988; in 1990, expanded to a 1-ha riparian plot and intensive monitoring started with 121 seed traps (n = 121); in 1993, expanded to 4.71 ha including riparian and beech stands (site construction completed).
