The Nouragues forestry experimental site is located the Nouragues experimental station in French Guiana (other experimental sites than Nouragues plots are established in Nouragues station). This experimental site is composed by several plots not contiguous, some of them are divided into smaller plots (1ha). For each plot, the following information is recorded for all trees and lianas with DBH ≥ 10cm : 1. location of individuals inside the plot, 2. botanical identification (when it is possible), 3. diameter at breast height, or 30 cm above last aerial root, last buttress or last irregularity, 4. total height of tree (subsample). Since 2012, on Grand Plateau and Petit Plateau : 1. coefficient of light exposure 2. coefficient of infestation by lianas in tree crown.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Monts d'Arawa is composed of 2 1ha-plots. A complete inventory has been made in 2006 : 1528 trees have been registrated. 512, 480 and 530 species have been identifies respectively on each plot. The percents of trees identified to the species level are : 99.6%, 99.8%, 99.4% on the 3 plots. 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 200 meters in each direction.

Guyadiv is a network of permanent forest plots installed in French Guiana. The Guyadiv plan in Crique Plomb and Montagne Plomb sites implements several types of plots and sampling methods: A first group of plots belongs to the Paget's plan, initiated in 1998. These 30x40m-plots are used for floristic and structural inventories.Then, 8 1ha-plots are used for floristic inventories concerning trees with DBH>10cm, since 2002 (campaigns in 2002, 2004 and 2005). These plots are located on greatly contrasted forest facies (high-density forest on thinned soils, forest on dismantled ferricrust, forest on deap DVL soils). The third type of sampling method is a "cluster points" (points-grappe) plan for floristic linear inventories. 18 points have been carried out, that is to say almost 8500m or 10ha of statements (ca. 5500 trees). 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 600 meters in each direction.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Eperon Barré is composed of two plots : one 1ha-plot and one 100x200m-plot. A complete inventory has been made in 2009 and 952 trees with dbh>=10cm have been registrated. 535 and 405 species have been identified in the two plots. 99,1% and 98,3% 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 these plots, we have expanded the point location 500 meters in each direction.

Several forest inventories in mangroves were conducted in different places and on different dates. Inventories take place at 6 main locations : Iracoubo, Sinnamary, Macouria, Cayenne, Petit Cayenne and Kaw. 1. at Iracoubo, forest inventories were carried out in 2003 and cover an area of 4800 m², 2. at Sinnamary, forest inventories were conducted in 1997, 2003 and 2004 on 9440 m², 3. at Macouria, 2824 m² were inventoried in 2006, 4. in the south-west of Cayenne, 10800 m² were inventoried in 1993, 5. at Petit-Cayenne, forest inventories were conducted in 2011 on 10000 m², 6. and in the Area of Kaw, three inventories in 2002, 2004 and 2005 cover an area of 34925 m². During the forest inventories, the collected data concern DBH, overall height or 1st branch height, the inter-trees distance in a forest plot, sometimes the surface salinity and state of the tree (living/dead).
