Description

  • This article looks at the ability of long-standing exotic pine plantations to aid in the establishment of native species in the understory and the effect that fire treatments have on those understory species.
  • The researchers evaluate the understory regeneration in 18-20 year old plantations of Pinus caribaea that underwent three different groundcover treatments: multiple times burned (within 5 years), once burned (within 5 years), and unburned.
  • The species richness and number of understory tree stems were highest in unburned plantations and lowest in the once burned plantations. 
  • Among all treatments, primary forest species that were shade-tolerant and had poor seed dispersal mechanism were largely missing, however the unburned plantations had a greater number of species that were considered primary rain forest species.
  • Along with the tree species diversity and counts, fern, vine, and bamboo growth was higher in unburned plantations.
  • Measures of soil productivity were significantly lower in multiple burned plantations, but in the once burned plantations soil measures were similar those in unburned plantations.
  • Meanwhile, the once-burned plantations had the lowest diversity of trees and shrubs compared with the other treatments. 
  • The authors propose that the one time fire might have been hotter and therefore had greater carbon inputs from burned plants while resulting in greater loss of vegetation and root collars (with coppicing ability). 
  • In this situation, the authors recommend that higher diversity of regeneration can be achieved by protecting plantations from fire and using nurse trees that do not increase forest flammability.
