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.

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 Montagne Tortue covers a 19,2ha area. It is composed of 3 plots managed by ONF. 9210 trees are being followed. 5 campaignes of inventories have been made in 2002, 2005, 2007, 2009, 2010.

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

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.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Massif des Emerillons is composed of 3 1ha-plots. A complete inventory has been made in 2007. 533, 482 and 455 trees with dbh>=10cm have been registrated respectively on each plot. 530 tree species have been identified in the first plot, 482 in the second plot and 453 in the third plot. 99.4%, 100% and 99.6% of the trees registrated have been identified to the species level respectively 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 500 meters in each direction.

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 Savane Roche Virginie is composed of three 1ha-plots. 3 complete inventories have been made in 2006, 2007 and 2008 : 1664 trees with dbh>=10cm have been registrated. 475, 507 and 657 species have been identified respectively to each plot. 97,9%, 99,2% and 98,4% of the inventoried 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 300 meters in each direction.

Guyadiv is a network of permanent forest plots installed in French Guiana. The ONF experimental site of Montagne Tortue is composed of 2 plots : one 1ha-plot and one 110x115m-plot. A complete inventory has been made in 2002 : 982 trees with dbh>=10cm have been registrated. 494 and 476 species have been identified. 98,2% and 99,4% 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 300 meters in each direction.
