Description

  • This study assesses the impact of the following harvesting methods, pit sawing and sawmilling of exotic species plantations on the colonization and regeneration of indigenous species in the grasslands of Kibale Forest Reserve, Uganda.
  • Tree enumeration was conducted to determine species richness and diversity. The data collected was analyzed using the Wilcoxon signed ranked test and a one-way ANOVA to identify the differences within and between exotic tree plantation and methods of harvesting on indigenous tree regeneration. 
  • The results showed higher number of tree species in the C. lusitanica and P. caribaea than in the Eucalytus. Pioneer, colonizing and secondary forest species contributed significantly to the density of the regeneration in logged exotic tree plantations. Pit sawing and sawmilling had little influence on species richness, but pit sawing enhanced higher tree regeneration densities.
  • The authors confer with other studies that C. lusitanica and P. caribaea could be used in afforestation, reforestation and accelerated natural forest colonization.
  • They recommend the establishment of selected exotic tree plantations next to natural forests with conducive nurse crop attributes and harvesting plantations at maturity could be both ecologically and socioeconomically viable means of afforesting and rehabilitating degraded terrestrial ecosystems.
