Description

  • This article details the results of a study of the potential of two exotic and five native tree species to restore degraded land in Costa Rica.
  • Thirty blocks were established over 25 hectares of abandoned cattle pasture and tree height was measured at 3 and 7 years and tree survival was measured after 7 years.
  • Across all of the blocks, P. tecunumanii exhibited the best growth and survival, while three native species (V. guatemalensis, T. amazonia, and C. brasilense) exhibited moderate growth and survival.
  • The highest mortality rates were observed in T. ochracea and E. deglupta.
  • The effects of erosion on survivorship and growth were also tested, with a negative correlation found between erosion and survival and/or growth in 5 of the 7 species; only P. tecunumanii did not appear to be affected by erosion.
  • The authors recommend utilizing the three more successful native species (V. guatemalensis, T. amazonia, and C. brasilense) on less eroded sites, while preference may be given to P. tecunumanii  on highly eroded sites.
  • The authors hypothesize that the pine species may have performed better than the natives species because it is ectomycorrhizal, suggesting that native species success may be improved with arbuscular mycorrhizal fungi inoculation.
