<p>This report documents 1) the construction of Community Weighted Means (CWMs) and Variance (CWVs); and 2) the classification of plots into forest\non-forest based on species growth forms. It complements species composition data from sPlot 3.0 and gap-filled plant functional traits from TRY 5.0, as received by <a href="jkattge@bgc-jena.mpg.de">Jens Kattge</a> on Jan 21, 2020.</p>
<p><em>Changes in version 1.1</em> - Standardized Growth form names in sPlot_traits.</p>
<p><em>Changes in version 1.1</em> - Standardized Growth form names in sPlot_traits.<br />
<em>Changes in version 1.2</em> - Improved match of species to traits, accounted for non standardized species in CWM completeness.</p>

<p>Through the process described above, we managed to classify 1628735, of which 468259 is forest and 1160476 is non-forest.<br />
The total number of plots with attribution to forest\non-forest (either coming from sPlot’s native classification, or from the process above) is: 1726506.</p>
