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 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.

The site Roche Koutou is composed of four 2 to 3km-transects (20m wide). 4411 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. 756 under-storey plants have been inventoried on 34 plots on this site (IRD). Soils have been described using 16 samples (1.20m depth max.). No laboratory analysis available for soils.

The site Toponowini is composed of four 3km-transects (20m wide). 4603 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. 506 under-storey plants have been recorded on 20 25m²-plots by Institut de recherche pour le développement (IRD). Soils have been described using 23 samples (1.20m depth max.). Laboratory analysis are available for two soil-profile.

The site Quartzites is composed of two 3km-transects (20m wide). 2638 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories available. 276 under-storey plants have been recorded on 17 25m²-plots by Institut de recherche pour le développement (IRD). Soils have been described using 13 samples (1.20m depth max.) and two soil pits (1.50m depth). Laboratory analyses are available for one profile and for the two soil pits

The site Piton de l'Armontabo is composed of four 3km-transects (20m wide). 4054 trees with dbh>=20cm have been recorded by Office National des Forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. There is no inventory of under-storey plants on this site. Soils have been described using 15 samples (1.20m depth max.). Laboratory analyses are available for one soil-profile.

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.

The site Yaroupi is composed of four 3km-transects (20m wide). 3965 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). Fauna inventories have been made by Office national de la chasse et de la faune sauvage (ONCFS) few days after. No under-storey plots on this site. Soils have been described using 22 samples (1.20m depth max.). Laboratory analysis are available for one soil-profile.
