CSPs: Tree growth of trees >10cm dbh in the CSPs (2008-2012)

Usage Rights

This data is Private.

Dataset 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).

Dataset 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

Published

2012 data has not yet been published. 2008--2010 data has been published in Baruffol et al (2013) PLoS ONE 8(12): 10.

Temporal Extent

Data were recorded between spring 2008 and autumn 2012.

Taxonomic Extent

Trees with DBH >= 10 cm

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.
