Central African rainforests are no longer considered as pristine, but as the outcome of a long history of changes due mainly to climatic variation. For the later part of the Holocene it has been hypothesised that climate changes together with human activities triggered modifications in terms of distribution and botanical composition. While developing a research project to explore the mechanisms of forest change, new research avenues for the archaeology of rainforests became apparent. In this paper, we outline the results of this approach, implemented on a forest concession (Cameroon). We introduce our methodology based on the analysis of botanical inventories (focused on large trees of human linked species and light demanding species), coupled to systematic core boring and test pits. A sampling strategy for the collection of charcoal and its identification is developed and archaeological remains found in association are analyzed at the Royal Museum for Central Africa. [less ▲]

The impact of the Pleistocene climate oscillations on the structure of biodiversity in tropical regions remains poorly understood. In this study, the forest refuge theory is examined at the molecular level in Milicia excelsa, a dioecious tree with a continuous range throughout tropical Africa. Eight nuclear microsatellites (nuSSRs) and two sequences and one microsatellite from chloroplast DNA (cpDNA) showed a deep divide between samples from Benin and those from Lower Guinea. This suggests both that these populations were isolated in separate geographical regions, probably for several glacial cycles of the Pleistocene, and a poor mixture of gene pools despite M. excelsa’s wind-pollination syndrome. The divide can also be related to seed dispersal patterns, which should be largely determined by the migration behaviour of M. excelsa's main seed disperser, the frugivorous bat Eidolon helvum. Within Lower Guinea, a north-south divide, observed with both markers despite weak genetic structure (nuSSRs: FST=0.035, cpDNA: GST=0.506), suggested the existence of separate Pleistocene refugia in Cameroon and the Gabon/Congo region. We inferred a pollen-to-seed dispersal distance ratio of 1.76, consistent with wide-ranging gene dispersal by both wind and bats. Simulations in an Approximate Bayesian Computation framework suggested low nuSSR and cpDNA mutation rates but imprecise estimates of other demographic parameters, probably due to a substantial gene flow between the Lower Guinean gene pools. The decline of genetic diversity detected in some Gabonese populations could be a consequence of the relatively recent establishment of a closed canopy forest which may negatively affect M. excelsa's reproductive system.

Les forêts communautaires constituent une des innovations sociales les plus importantes de la nouvelle loi n° 016/01 portant code forestier au Gabon. Cet article détaille les différentes parties de la loi relatives à ces dernières et fournit une première interprétation de l’esprit de cette loi et de la volonté du législateur. Les grands thèmes qui y sont défendus tournent autour de la communauté locale, de la décentralisation de la gestion des ressources, de l’aménagement et de la gratuité. La volonté de l’état gabonais d’associer les populations à la gestion de la forêt dans l’optique de contribuer à la réduction de la pauvreté est évidente. [less ▲]

The new generation of hypsometers, of which the Swedish Forestor Vertex is representative, use ultrasonic pulses to determine heights from 0 to 100 m, as well as distances and angles. The authors describe the operating principle for this hypsometer and point out some precautions that should be taken when using it. They highlight its main advantages and provide data on its precision. [less ▲]

Au Gabon, la gestion d’une forêt communautaire devrait reposer sur un plan simple de gestion, document qui a pour objectif d’orienter à moyen et à long termes les activités entreprises par les communautés villageoises. Les expériences précédentes en matière foresterie communautaire en Afrique centrale ont mis en évidence des modalités d’élaboration de plans de gestion trop complexes et trop onéreuses pour les communautés villageoises. Cet article se propose de présenter une méthodologie pour concevoir des plans de gestion réellement simples, réalistes, participatifs, peu coûteux et respectant le cadre légal gabonais en vigueur. Ces plans simples de gestion sont basés sur un aménagement par contenance, un inventaire d’exploitation multi-ressource, une cartographie simplifi ée et des normes de gestion pragmatiques. Les résultats sont présentés pour deux sites partenaires du projet DACEFI, le village de La Scierie et le regroupement de villages de Ebe Messe Melane. [less ▲]
