Stem quality data for all exploratory plots

Usage Rights

This data is Free for members.

Dataset Design

Each tree in all plots was sampled for stem quality characteristics (score, deformation, defects, straightness, etc.)

Spatial Extent

All trees of all plots in the exploratory platform were sampled during one 8 month campaign in 2012

Data Analysis

Quality score, epicormic branching, curving, lean, branch free bole length - model effect of diversity, tree/plot/region/species effects on stem quality

Data columns available in the raw data part of this dataset
