TreeSource is the National database on wood and trees quality in Canada. Developped by the [Canadian Wood Fibre Centre](http://www.nrcan.gc.ca/forests/research-centres/cwfc/13457), it aims to gather the largest possible amount of information on trees quality (dendrometry, physico-mechanical and chemical properties) for economically important species across Canada, for research purposes.

Data are accessible for the whole forest sector (governments, academia, industry).

With more than **740 000 trees**, both coniferous and deciduous, **over 1.7 millions dendrometrical measurements**, and nearly **20 000** samples analyzed for **physico-mechanical properties** (wood density, MFA), TreeSource stands as the largest reference database on the topic.
