Description

  • This article summarizes the economic and ecological benefits of promoting a mixed species plantation on abandoned agricultural forests as opposed to monoculture plantations. This article uses studies from across the globe to demonstrate successful plantation designs.
  • Kelty argues that planting species with different phenologies, such as shade tolerance, height growth rate, crown structure, and foliar  and root depth phenology, improves a species' ability to capture more of  the available resources and thus increase growth and production (intraspecies competition can be more damaging than interspecies competition).
  • Mixed species plantations can also benefit from the facilitative interactions of different species (such as the benefits of N-fixing plants in nitrogen poor soils for improving site condition for other plants, i.e. Eucalyptus saligna and the N-fixing Falcataria moluccana).
  • Growing a mixed species plantation can reduce market risk by diversifying products and reducing the probability of pests and pathogens.
  • Finally, the planting of mixed species can faciliate forest restoration of abandoned agricultural sites and restore degraded landscapes to natural vegetation by the sequential introductions of different species with different characteristics.
