Description

  • This study examines differences in survival and growth of native species in pure and mixed-species plantations treated with varying degrees of thinning, with a focus on the applicability to long-term management of native species plantations for owners of small and medium-sized farms.
  • Three plantations with four species each, including pure and mixed-species plots, were established; each plot was divided in half, with one half thinned and the other not thinned.
  • Measurements were compared between both pure and mixed-species plots, and between thinned and non-thinned plots.
  • In all three plantations, all species showed better survival in the mixed-species plots, with the exception of Genipa americana which had lower survival, diameter and height growth in the mixed-species plots.
  • Differences in tree diameter were significantly higher in the thinned subplots versus the non-thinned subplots, except for H. alchorneoides and B. elegans.
  • Basal area and tree volume were found to be highest in the non-thinned subplots.
  • By species, the trees with the best growth were V. guatemalensis, T. amazonia, J. copaia, V. koschnyi and V. ferruginea.
  • In pure-stands, the species with the best growth were C. brasiliense and G. americana.
