  • The study examine the impacts of second logging cycle on biodiversity by comparing species richness, species composition and population-level responses of birds and dung beetle species across unlogged forest, first rotation forest and second rotation forest in Sabah, Malaysia.
  • 18 sites, 6 for each forest type, were sampled over a two year period from 2007 to 2009, through standardised point count and mist net census for bird species while pitfall traps were used for dung beetle counts.
  • The study revealed that species richness did not decline between the three forest types, but there were significant difference in the species composition with a loss of endemic species only during the second rotation.
  • Given that 75% of birds and dung beetle species found in unlogged forest were also presence after the second rotation, the authors suggested that second rotation forest may be worthy of conservation and should not be put up as a natural choice for conversion to plantations.
