Atelier sur la gestion de la faune sur les concessions de l'exploitation forestiere d' Afrique centrale
Community-based forest management has been promoted widely to enable local communities capture the value of the forests they inhabit. Most community forests have focused on non-timber forest products. In Cameroon, the 1994 Forest Law introduced community forestry with a strong emphasis on timber ...

External influences on and conditions for community logging management in Cameroon
Selective logging applied in tropical forests is based on one universal criterion: a minimum diameter cutting limit for all commercial timber species. Minimum diameter cutting limits in mixed dipterocarp forests of the Malesia region lead to high felling intensities (10–20+ trees per hectare). Su...

In this paper we seek to identify the floristic determination biases contained in large-scale commercial inventories conducted by logging companies and to determine whether this impacts on the observed patterns of alpha and beta diversity. The study focused on floristic data recently collected by...

Detecting large-scale diversity patterns in tropical trees: can we trust commercial forest inventories?
Tropical deforestation is leading to a loss of economically productive timber concessions, as well as areas with important environmental or socio-cultural values. To counteract this threat in Southeast Asia, sustainable forest management (SFM) practices are becoming increasingly important. We ass...

Logging concessions can affect wildlife populations through indirect or direct effects. However, if wildlife is appropriately taken into account in the forest management plans, then logging concessions can become an opportunity for conservation, as they can play a crucial role as buffers around p...

Using landscape approaches to improve the integration of wildlife in forest management plans
Based on an extensive review of the literature, and broad consultation with experts, we have assessed the sensitivity of Bornean vertebrates to the direct and indirect effects of timber harvest. Well-implemented selective logging has a relatively limited direct impact on wildlife populations: few...
