The UMR EcoFoG possesses an herbarium reference collection based on samples harvested all along the different forest plots studied by our teams. This collection is maintained by a botanist and stored on the Agronomical Campus of Kourou, INRA building. A Excel database is linked to this collection and the taxa found in it are listed in the Guyafor database. The collection gathers more than 3000 samples representing 74 families, 288 genera and…

The project Bridging Information on Tree Diversity in French Guiana, and a Test of Ecological Theories (BRIDGE) brings together researchers from nine different European research groups in tropical ecology, and seeks to improve our knowledge on the various dimensions of tree biological diversity in French Guiana. The project includes ten one-hectare old-growth forest tree plots across a range of geology and rainfall in French Guiana. The amount…

Guyadiv is a network of permanent forest plots installed in French Guiana. The site Piton de l'Armontabo is composed of one 1ha-plot. A complete inventory of this plot has been made in 2006 : 538 trees with dbh>=10cm have been registrated and 533 species have been identified. 99,1% of the registrated trees have been identified to the species level. We only have the point coordinates and not the precise demarcation of the sample plot. In…

The experimental site of Guyaflux in the Paracou forest (Sinnamary, French Guiana) has been created in 2003 and is set up for at least 20 years. Guyaflux has several aims : 1. to characterise the greenhouse gases exchanges between the forest ecosystem and the atmosphere. 2. to assess the contribution of Guianese tropical humid forest ecosystem to the biospheric carbon sink. 3. to assess the impact of environmental constraints on carbon…
