Uneven-aged silviculture, southern style
Data spanning 60 years on uneven-aged loblolly-shortleaf pine stands in Arkansas show that two regulation methods have been successful in regulating stand development. Key attributes of these methods are that regulation is more important than balance, residual basal area drives stand development, and regeneration is the first indicator of sustainability. Marking uneven-aged stands is best kept simple: mark to cut the poorest trees and leave the best, regardless of target structure or method of regeneration. To be successful in the long term, new methods of regulating uneven-aged and multiaged stands should share these attributes.
