Description

  • This research evaluates the structure (basal area, height, tree density, species diversity) and dynamics (basal area growth, height growth, mortality, recruitment) of tree plantations of (10, 9, and 5 years-old) in Sao Paulo state Brazil.
  • The 10 year-old plantations were planted in 3:2 mixtures of pioneer:non-pioneer species, and the 5 and 9 year-old plantations were planted with 4:1 mixtures of pioneer:non-pioneer species.
  • The researches identified and measured (height and DBH) stems with a greater than 4.8 cm DBH for both planted and regenerating trees.
  • In six 1m radius subplots, woody plants above 50cm in height and less than 4.8cm DBH were counted, measured, and identified.
  • In the 10 year old plantations, the overstory was dominated (44.5% tree density) by Cecropia pachystachya, Croton floribundus, Genipa americana, and Peltophorum dubium.
  • In the 5 an 9 year old plantations, the overstory was dominated (50% tree density) by Croton floribundus and Cecropia pachystachya.
  • Overall, the parameters for structure and dynamics were not significantly different between plantation designs.
  • The density and diversity of regenerating individuals was low compared with natural and other restoration forests.
  • Even though canopy closure appeared to arise before 5 years of age, the plantations still had a large abundance of grasses.
  • The authors suggest that if there are natural forest patches nearby, the higher proportion of pioneer to non-pioneer design may be preferred; but if there are not nearby sources of plant and wildlife species, planting a lower proportion of pioneer to non-pioneer species is preferred.
