Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Montagne des Chevaux is composed of 3 plots : one 1ha-plot, one 125x100m-plot, one 120x131m-plot. A complete inventory of the trees has been made in 2009. 2161 trees with dbh>=10cm have been registrated, 699 species have been identified in the first plot, 656 in the second plot and 757 in the third plot. 98.9%, 97% and 97.3% of the inventoried trees have been determined to the species level. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 300 meters in each direction.
