Description

  • This article summarizes a symposium on the role of plantations in the restoration of degraded tropical lands and includes recommendations for further research.
  • Research suggests that plantations may create favorable microclimates for the establishment of native species, while also aiding the development of litter and humus layers and encouraging seed dispersal by wildlife.
  • Plantation species may eventually be removed without disturbing woody understory regeneration to allow the development of secondary forest.
  • Plantations have been seen to catalyze native forest regeneration on severely degraded sites (such as mined or highly eroded land) and grass-dominated sites.
  • Furthermore, plantations tend to catalyze secondary forest growth better in drier sites closer to primary forest stands.
  • The species composition of plantations effects the resulting species composition and richness of the understory growth, with broadleaf species and mixed-species plantations yielding more favorable results.
  • Enrichment plantings of large-seeded forest species may be necessary to overcome seed dispersal barriers.
  • The authors recommend selecting fast-growing pioneer species as plantation trees, with preference for native species where possible.
