Does basal area increase in stand age? Is Beech regeneration increasing? Is Sugar Maple failing to regenerate? Slide 5 Slide 6 Slide 7 Slide 8 Slide 9 Slide 10 Slide 11 Results Basal area increases as stand age increases. Early succession species decrease in mid-age stands. Late successional species increasing in mid and mature forest. In two stands which we have three inventories: Sugar Maple regeneration is decreasing Beech regeneration is increasing Slide 12 Future Work Inventory remaining stands. Change in biomass across stand ages? At what age is biomass greatest? Stand growth according to available soil nutrients? At what point does species composition change?
