Macroscopic charcoal fragments were systematically recorded through auger investigations and pits observations in four forest types: the open canopy Marantaceae forest, the dense forest with Marantaceae, the Gilbertiodendron dewevrei forest and the Triplochiton scleroxylon forest. In addition, the charred Elaies guineensis seeds were distinguished from the other charcoals in the pits. Ten selected charcoals, including charred E. guineensis seeds, were dated by AMS. Abundance of charcoal fragments in the soils at various depths indicated several episodes of fires in the region. A dryer climatic phase, between 2320 and 1330 BP, associated with a large scale human occupation related to the important harvesting of oil palm nuts, could explain the widespread Marantaceae forests. Recent slash-and-burn shifting cultivation, c. 200 BP, would allow T. scleroxylon installation. Implications for forest management are discussed. http://hdl.handle.net/2268/148531 Title: Base de données des relevés phytosociologiques <br/> <br/>Author, co-author: Dufrêne, Marc http://hdl.handle.net/2268/148497 Title: Nouvelles estimations des effectifs de l’Agrion de Mercure (Coenagrion mercuriale) dans la plaine du Biran (Commune de Beauraing, Belgique) avec une analyse des principaux facteurs écologiques expliquant son abondance. <br/> <br/>Author, co-author: Couvreur, Jean-Marc; Dufrêne, Marc; Goffart, Philippe; Vandevyvre, Xavier; Etienne, Fabrice; Testart, D. http://hdl.handle.net/2268/148424 Title: Le stockage sous bâches de grumes <br/> <br/>Author, co-author: Riguelle, Simon; Jourez, Benoît http://hdl.handle.net/2268/148420 Title: Visualisation des données de l'Atlas de la Flore de Wallonie <br/> <br/>Author, co-author: Dufrêne, Marc http://hdl.handle.net/2268/148419 Title: Portail "Biodiversité en Wallonie" <br/> <br/>Author, co-author: Dufrêne, Marc; Grenson, Michel; Barbier, Yvan http://hdl.handle.net/2268/148418 Title: La cartographie des sites Natura 2000 : méthodologie et développement des outils nécessaires. <br/> <br/>Author, co-author: Dufrêne, Marc; Delescaille; Derochette, Luc http://hdl.handle.net/2268/148404 Title: Stockage de bois sous bâches hermétiques <br/> <br/>Author, co-author: Riguelle, Simon http://hdl.handle.net/2268/148392 Title: Développement d'un outil d'aide à la décision pour la gestion des chablis en Région wallonne <br/> <br/>Author, co-author: Riguelle, Simon <br/> <br/>Editor: Jourez, Benoît; Hebert, Jacques http://hdl.handle.net/2268/148384 Title: Outils et procédures pour l'inventaire de chablis <br/> <br/>Author, co-author: Riguelle, Simon; Jourez, Benoît; Hebert, Jacques; Lejeune, Philippe http://hdl.handle.net/2268/148374 Title: Some calcareous grasslands plant species harbor higher reproductive performances in restored habitats compared to reference habitats <br/> <br/>Author, co-author: Harzé, Mélanie; Bizoux, Jean-Philippe; Piqueray, Julien; Mahy, Grégory http://hdl.handle.net/2268/148364 Title: Développement d’un outil dynamique d’aide à la décision pour la gestion des chablis en Région wallonne.
