Description

  • This study assesses the potential for artificial gap openings to serve as a silvicultural method for logged-over dipterocarp forests, as many currently applied management and harvesting systems in tropical rainforests may not provide sustainable forest management based on patterns of regeneration and growth after logging.
  • Five artificial forest gaps (ranging from 406 to 1242 m2) were opened up randomly in a logged-over dipterocarp forest in South Kalimantan, Indonesia, in 1987.  Pioneer trees and climbers were slashed in 1990. 
  • in 1993, after 6 years, the growth of dipterocarp seedlings in artificial gaps was faster than in the surrounding forest.
  • It was also found that the growth of dipterocarp seedlings was fastest in relatively small gaps (less than 500m2), and that the growth of dipterocarp seedlings depended on gap size independently of the species concerned.
  • The authors confirm that it is feasible to simulate the natural regeneration pattern of dipterocarps as a silvicultural strategy.
  • Assisted natural regeneration and promoting the early growth of dipterocarps through the opening of forest gaps (with gap sizes smaller than 500m2) is recommended as an alternative to other post-logging operation strategies.
