Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Wayapi Trois Sauts is composed of one 20x400m-plot. A complete inventory has been made in 1989 : 419 trees with dbh>=10cm have been registrated and 321 species have been identified. 76,6% 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 plots. In order to calculate the bounding box for the plot, we have expanded the point location 400 meters in each direction.

The Paracou Research Station encompasses 5000 ha of tropical rain forest near Sinnamary, French Guiana, and is accessible by paved road. The site includes several types of forest plots, each with unique research objectives. Logging Plots: Fifteen nine-hectare plots (numberred 1 to 15) were established in 1984 to study the impact of different logging treatments on tropical tree population structure. This zone is reserved exclusively for studies investigating the impact of the different logging treatments on forest populations. Primary Forest Plot: A 25 hectare plot (no. 16) was established in 1991 for studies of undisturbed forest. Researchers whose interests are unrelated to the effects of logging treatments are encouraged to conduct their work in this plot. Clearcut Plot: a 6.25 ha plot (no. 17) was established in 1989 at a nearby reserve along the road to St. Elie to study the effects of clearcutting on tropical forest dynamics

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Paracou covers a 130,5ha area. It is composed of 16 plots, managed by CIRAD. 114373 trees are being followed since 1984. 30 campaignes of inventories have been made : every year since 1984.
