Subtropical forest vegetation along elevation gradient in Taiwan: Lalashan transect
Source of data
Zelený, Li, Shen, Chen et al. (data collected within Vegetation Ecology Lab, NTU)
Description of the dataset
Vegetation plots (20 m x 20 m) with recorded all woody species with DBH > 1 cm and taller than 2 m. A set of leaf and wood traits have been sampled for most of the species recorded in the dataset (measurement was done three leaves per individual, and for each species we collected at least three individuals along the transect). Topography, soil, light, decomposition and microclimate data are also available.
