| Abstract: | A dendrochronological technique was used to investigate canopy recruitment of beech (Fagus engleriana Seem.) trees in western Hubei Province of Central China by identifying growth releases through gap formation. The results
indicated that 83% and 17% of the canopy trees regenerate in gaps and the understory, respectively. Radial growth analyses
demonstrated that there are three modes for beech regeneration and canopy recruitment: (1) gap origin without suppression;
(2) gap origin with period(s) of suppression; and (3) understory origin. Multiple periods of release and suppression imply
that beech regeneration and canopy recruitment are very sensitive to gap formation. |
