What is TreeSource?
TreeSource is the National database on wood and trees quality in Canada. Developped by the Canadian Wood Fibre Centre, 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. For more contents statistics, see below.
