Species Info

  • Gliricidia sepium
  • Bursera simaruba

Description

  • In this article, the authors test the effectiveness of tree islands in abandoned pasture to recruit regeneration given various experimental conditions: changes in tree island size and distance to forest.
  • In three deforested sites in Honduras, single-species tree islands of Gliricidia sepium and Bursera simaruba were planted at 20 and 50m from forest edge in plots of 64, 16, and 4 square meters.
  • At two years after planting, seed rain and seedling establishment were tested in the understories of the plots as well as in open pasture.
  • Tree islands were found to increase the seed rain (especially animal-disperesed seeds) compared with open pasture and more frigivores visited the large Gliricidia islands than the small Gliricidia islands. Gliricidia islands had higher density of seedlings as Bursera.
  • Seed rain was not affected by distance to forest.
  • Meanwhile, seedling density did not appear to be affected by treatment.
  • However, the authors assert that there may not have been enough time for germination to occur under the tree islands.
  • Because similar seedling density was found in the perimeter around the islands, the authors suggest that tree islands can expand into the pasture.
