Examples are used to illustrate the different present-day forms of forest management, based first and foremost on decision-making procedures governing management choices rather than on technical criteria governing the choice and implementation of programmes. These examples range from the Gabonese...

L'adaption de l'amengement forestier a des situations diverses
The various factors common to forest management schemes are examined : sustained output, biodiversity conservation, and multiple uses. These factors are combined in different ways from case to case. Consideration of them in the management process includes specific kinds of financial impact for ea...

Variations in the natural 13C abundance of soil organic matter (SOM) at different depths combined with SOM radiocarbon dating were used to reconstruct the history of the forest-savanna successions over the last millennium in the Gabon coastal area. A chronosequence was established by comparing th...

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...

Dung counts have been widely used to estimate duiker abundance and densities in tropical African forests. However, one of the major limitations of this method is that species’ identification of dung based on morphological characteristics is extremely difficult in most cases. Some authors made the...

We analysed seasonality of dung decay time and the influence of rainfall, leaf fall, beetle attack and moisture on dung decay. Our study was carried out at the Ipassa Reserve, north-east Gabon. We compared the seasonality of dung decay with the seasonality of dung beetle abundance and guild struc...
