Description

  • The authors of this study looked at fallows of varying age within systems of shifting cultivation to understand factors that influence their recovery. The authors focused on the role of duration of cultivation and cropping history in influencing recovery. All cropping systems in the area are shade intolerant.
  • Primary forests, farms, and fallow areas were surveyed for basal area, stand complexity, and diversity (Fisher's alpha).
  • Elevation influenced recovery with submontane (800-1600 m) fallows had significantly greater basal area and stand complexity than lowland (300-800 m) fallows, though even after 31 years none of the fallows equaled primary forest values.
  • Fallow age, elevation, and cultivation duration had a significant effect on recovery, while cropping history did not.
  • Lowland fallows had a higher diversity than primary forests.
  • Fallows with primary/dense forest nearby recovered fastest.
  • Recommendations for improving recovery of fallows include planned use of remnant trees, significantly shorter cultivation times, and assisted regeneration.
