The creation of natural canopy gaps is an important ecological process in the Acadian forest. Designing harvest gaps that emulate natural gap dynamics may be important for maintaining structural and biological diversity, as well as naturally regenerating desired tree species. We used a controlled study to 1) compare vegetation dynamics among and within harvested gaps, natural gaps, and under a closed canopy, and 2) examine the growth response of mature overstory edge trees of harvests gap and saplings inside of gaps as possible methods for dating natural gaps in the Acadian forest. For the vegetation dynamics study (objective I), we …
