Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Rivière Grand Inini is composed of two 20x500m-plots. A complete inventory has been made in 1990 : 1266 trees with dbh>=10cm have been registrated. 621 species have been identified in the first plot and 639 in the second plot. 99,7% and 99, 4% of the registrated trees have been identified to the species level, respectively on 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.

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.

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.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Crique Cacao is composed of two plots (20x530m and 20x200m). A complete inventory has been made in 1987, 662 trees with dbh >= 10cm have been inventoried. In the first plot, 433 species have been determined and 193 in the second plot. The percentages of trees identified to the species level are respectively 93.7% and 96.5% for 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.

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 site Piton de l'Armontabo is composed of one 1ha-plot. A complete inventory of this plot has been made in 2006 : 538 trees with dbh>=10cm have been registrated and 533 species have been identified. 99,1% 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 plot. In order to calculate the bounding box for the plots, we have expanded the point location 100 meters in each direction.

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 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 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.
