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.

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Acarouany (Javouhey) covers 6ha. It is composed of one plot, managed by CIRAD. 2872 trees are being followed. A first inventory campaign has been made in 2006, a second one in 2008, and a third one in 2012.

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Risquetout covers a 23,7ha area. It is composed of 4 plots managed by ONF. 7174 trees are being followed since 1995. 9 campaignes of inventories have been made in 1995, 1999, 2001, 2002, 2003, 2004, 2006, 2008, 2009.

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Laussat covers a 4ha area. It is composed of one plot, managed by CIRAD. 2334 trees are being followed. A first inventory has been made in 2009

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).

Guyadiv is a network of permanent forest plots in French Guiana. The experimental site of Piste de St Elie is composed of one 10-ha plot (100 m x 1000 m), an adjacent 2-ha plot (100 m x 200 m), and three distant plots: a 5-ha (100 m x 500 m) and two 1-ha (19 ha total area). These plots are located in the ECEREX area of Piste Saint Elie. The botanists who have set-up the plots and contributed to identification and tree measurements are D. Sabatier, M.-F. Prévost, J.-F. Molino, B. Riéra, E. Fonty and C. Madelaine. During the inventories, the data recorded are: geographical position of the trees, dbh and identification by botanical sampling. On all 19 plots, all trees above10 cm dbh were censused. On a 1-ha plot (20 m x 500 m) nested within the 10-ha plot, all trees above 2 cm dbh were also censused. The first year of inventory of trees with dbh >= 10 cm was 1986, 1987, 1988 or 1991 (depending on the plots), and 1994 for trees with dbh between 2 and 10 cm. A second inventory was conducted in 2003 on the 10-ha plot (including trees with dbh between 2 and 10 cm) and the two distant 1-ha plots.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Haute Beiman is composed of two 1ha-plots. A complete inventory of the trees has been made in 2012. 645 and 507 trees with dbh>=10cm have been registrated, respectively to each plot. 613 and 465 species have been identified. 95% of the trees in the first plot have been identified to the species level, and 91.7% in the second plot. 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.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Mont Itoupé is composed of 10 20x120m-plots. An incomplete inventory on the pool of trees with dbh>=10cm has been made in 2010. 104 trees by plot have been registrated (except one plot with 102 trees inventoried). 104, 103, 101, 103, 104, 96, 102, 104, 99, 103 species have been identified, respectively to each plot. 100%, 99%, 97.1%, 99%, 100%, 92.3%, 98.1%, 100%, 97.1% and 99% of the inventoried trees have been identified to the level of species, respectively to each plot. 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.
