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.

This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 59 895 ha. 34 016 trees have been inventoried in 244 plots (120 ha) Pre-census DBH is 15 cm on all plot (originally trees with DBH 10-15cm have been measured on one plot out of 10 but not included in the digital version) DBH have been measured by classes : 15-20 cm for the first class and with a range of 10 cm since 20 cm. Plots have been located on GIS in 2008 using original maps and field note-books (indicating slopes, rivers, etc...).

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.

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).

The site Paracou is composed of two 3km-transects (20m wide). 2438 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories. No under-storey plants inventory. Soils have been described using 6 samples (1.20m depth max.). No laboratory analysis available for soils.

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.

This database contains botanical records either relating to material present in one of the Naturalis collections, or to material that has been or is being used in research projects. The records usually relate to herbarium specimens, but it also contains data on silica-gel samples, wood samples, spirit collections, carpological collections, etc.; rarely to observations only. The Naturalis collections have their strong points in The Netherlands and surrounding countries, Southeast Asia and New Guinea, West- and Central-Africa, Ethiopia and the Guyanas.

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 Régina is composed of two 3km-transects (20m wide). 1958 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories available. 284 under-storey plants have been recorded on 14 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

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Tibourou covers a 6ha area. It is composed of one plot managed by CIRAD. 2817 trees are being followed since 2006. 3 campaignes of inventories have been made in 2006, 2009 and 2012.
