A regional perspective on the effects of human disturbance on the termites of Sundaland

The remains of the rainforests of Sundaland are threatened by logging,burning and conversion to agriculture. In this study theeffects of different levels of disturbance and recovery on termites wereexamined. This was carried out on a regional scale and incorporated sixdifferent disturbance effects. Termites were found to be strongly effected bydisturbance, particularly by complete removal of the forest canopy. Recoveryfrom severe disturbance is discussed and we find that completely cleared andfarmed land, when left fallow near to a source area of primary forest for over50 years, can completely recover its termite assemblage andassociated ecosystem services. Over larger areas termites do not recover fromdisturbance events for millennia. The conservation implications of our findingsare discussed, with reference to both the conservation of species and ofecosystem services. We propose that most Sundan termite species can be conservedin a relatively small area. However, termite composition and ecosystem processesthroughout the region may be altered forever, if current widespread rainforestdestruction is not halted.     

The Tropical managed Forests Observatory: a research network addressing the future of tropical logged forests

While attention on logging in the tropics has been increasing, studies on the long-term effects of silviculture on forest dynamics and ecology remain scare and spatially limited. Indeed, most of our knowledge on tropical forests arises from studies carried out in undisturbed tropical forests. This bias is problematic given that logged and disturbed tropical forests are now covering a larger area than the so-called primary forests. A new network of permanent sample plots in logged forests, the Tropical managed Forests Observatory (TmFO), aims to fill this gap by providing unprecedented opportunities to examine long-term data on the resilience of logged tropical forests at regional and global scales. TmFO currently includes 24 experimental sites distributed across three tropical regions, with a total of 490 permanent plots and 921 ha of forest inventories.
