Species Info

70 Native Tree Species

Description

  • This article evaluates the diversity of species in a 10 year old native species plantation in the Para state of Brazil.
  • The study site was mined for bauxite in 1984 and planted in 1985 with 70 species of native forest tree species.
  • In 1995, plots were established in the reforestation area in which all of the trees, shrubs, vines, herbs, and grasses were inventoried.
  • Additionally, soil characteristics, canopy closure, wildlife presence and mychorrizal spores were measured.
  • The diversity and density of understory plant species was strongly correlated with the diversity of the planted species.
  • Species diversity decreased with distance from primary forest edge and increased with planted tree basal area.
  • The capture rate of birds was about 4.2 per 100 net hours, whereas the capture of bats was about 147 per 100 hours with the nets.
  • Smaller-seeded species were in higher proportion than larger-seeded species, which may require enrichment planting to improve diversity.
