Abstract:
To test the effect of diversity on stand productivity, in summer 2018 and 2012 we measure the diameter at breast height (DBH) of alI individuals with a DBH of at least 10 cm. In 2012, we also measured the height (parallel to the stem if the tree was leaning) of the same trees with a hypsometer (Vertex III, Haglöf AB, Sweden).
Design:
In 2008, 27 plots were established. The size of each plot was 30 m x 30 m. We marked all trees with a DBH of at least 10 cm and monitor their growth in 2008 and 2012.
Spatial extent:
Comparative study plots (CSPs) 29°08'-29°17'N 118°02'-118°11'E
Temporal extent:
Data were recorded between spring 2008 and autumn 2012.
Taxonomic extent:
Trees with DBH >= 10 cm
Measurement cirumstances:
No information available
Data analysis:
We estimate stand basal area (2008 and 2012) and carbon stock in the aboveground biomass (2012). Both pararemeters are analzyed as a function of tree species richness.
