TreeSource is the National database on wood and trees quality in Canada. Developed by the [Canadian Forest Service](https://natural-resources.canada.ca/corporate/corporate-overview/canadian-forest-service), 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 **790 000 trees**, both coniferous and deciduous, **over 1.7 millions dendrometrical measurements**, and nearly **22 000** samples analyzed for **physico-mechanical properties** (wood density, MFA), TreeSource stands as the largest reference database on the topic. TreeSource is also host to the [CFS-TRenD database](https://ts.rncan.gc.ca/en/treerings), a collection of more than **17 millions** growth rings from Canadian Forest Service projects.
