Measured traits in descending order are acoustic velocity at age 16 as a proxy for wood stiffness, average wood density at age 15, microfibril angle at age 15, diameter at breast height at age 15, tree height at age 15, the height‐to‐diameter ratio at age 15, and the cumulative number of weevil attacks.
Experimental sites Grandes‐Piles (GPI) and Saint‐Modeste (STM).
