Description

  • This article provides information on the role of seed-dispersal in forest regeneration.
  • In natural forest, species with animal-dispersed species tend to predominated in both early and mid-stages of succession, while wind-dispersed species tend to be vines and canopy species.
  • The implications of wind versus animal seed dispersal are briefly summarized.
  • Traits of the site which attract seed dispersers are also discussed, including the use of perches, increased structural complexity of the vegetation and the presence of fruiting plants.
  • With regard to perches, the author states that perches attract bird seed dispersers when at a height above the level of herbaceous vegetation. 
  • The distance of a site to a potential seed source, as well as the size of the seeds affect natural regeneration success.
  • Relative to small seeds, the seed dispersal range of large seeds is proportionally much smaller. 
  • The author recommends careful consideration of these implications when implementing a restoration plan relying on some natural regeneration, including the use of perches, fruit-bearing trees, appropriate species composition, and enrichment planting of large seeded species.
