What to write about
Data corrections come first: if a value here disagrees with the USDA Wood Handbook or another primary source, say which page and which figure, and it will be checked against the source and fixed.
Also welcome: suggestions for species or tools to add, questions about how a calculation works, and questions about reusing the data (the underlying USDA source is public domain; this site's original text is not).
Response time
This is a small independent project, not a staffed help desk — expect a reply within a few days. Correction reports are prioritized.
