Proceedings of Past Forest Nursery Association Meetings:

The Development of Mixed Species Plantations as Successional Analogues to Natural Forest
P. Mark S. Ashton and Mark J. Ducey
1996: New England, CT
Moist temperate and tropical forests often regenerate after disturbance regimes (hurricanes, tree falls, pathogens) that promote allogenic processes (initial floristics) of stand development. Disturbance regimes that are more lethal to advance regeneration, such as land clearance for agriculture and subsequent abandonment, promote autogenic processes (relay floristics) of stand development. We propose models for development of mixed plantations that reflect these successional patterns. Initial findings from experiments adopting guidelines that carefully consider the spatial arrangement and timing of mixed plantings can promote the inclusion of late-successional canopy timber species with subcanopy species that provide non-timber forest products (latex, spices, medicinal herbs, fruits). Past experiments have demonstrated poor establishment of subcanopy and late-seral tree species when planted as a single species in open conditions.
