Management in the production forest concessions of the Congo Basin is based on rotation principles, with the concessionary industry involved at every stage in the drafting and implementation of the felling permit granted. In this process, forest organization by area, based on management inventory...

Reflexion sur l'amenagement des forets de production dans le basin du Congo
Due to the need for forest certification, the criteria and indicators for sustainable management of tropical forests have tended to operate more and more as standards, with criteria holding pride of place as compared to indicators. In practice, they are used as the definition of sustainability ap...

Most of the world’s biodiversity will continue to exist outside protected areas and there are also managed lands within many protected areas. In the assessment of millennium targets, there is therefore a need for indicators to measure biodiversity and suitability of habitats for biodiversity both...

Measuring biodiversity and sustainable management in forests and agricultural landscapes
The relationship between trees, grass and soil in a dry savanna in Mali was investigated, to identify variables that are most relevant to assess vegetation units. A 65 ha plateau was inventoried using a systematic square grid sampling pattern. Thirteen soil or topography variables, and tree and g...

The high species diversity of mixed tropical forests hinders the development of forest dynamic models. A solution commonly adopted is to cluster species in groups. There are various methods for grouping species that can be linked to three strategies (i) the ecological subjective strategy, (ii) th...

Who is logging the Congo?: a multi-country characterization of timber companies
Tropical forests could satisfy multiple demands for goods and services both for present and future generations. Yet integrated approaches to natural forest management remain elusive across the tropics. In this paper we examine one combination of uses: selective harvesting of timber and non-timber...

The Brazilian Amazon is a significant source of timber as well as a rich source of non-timber forest products (NTFPs) such as medicinal barks, oils and fruits. Lack of quantity, quality, uniformity and price as well as a lack understanding of NTFPs socioeconomic, cultural or spiritual value and f...

From conflict of use to multiple use: forest management innovations by small holders in Amazonian logging frontiers
Today in the Central Africa region, production forests under management cover an area similar to that of protected forests. This is the result of a complex process initiated about 10 years ago, after a long gestation history and a sudden increase in speed in the mid 90s. Managed forests should be...
