Forest edge disturbance increases rattan abundance in tropical rain forest fragments

Abstract Human-induced forest fragmentation poses one of the largest threats to global diversity yet its impact on rattans (climbing palms) has remained virtually unexplored. Rattan is arguably the world’s most valuable non-timber forest product though current levels of harvesting and land-use chang...

Rattan is arguably the world’s most valuable non-timber forest product though current levels of harvesting and land-use change place wild populations at risk. To assess rattan response to fragmentation exclusive of harvesting impacts we examined rattan abundance, demography and ecology within the forests of northeastern, Australia.
