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 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 Guyafor site of Nouragues covers a 3ha area (Parare plots). It is managed by CNRS. 18916 trees are being followed. 8 campaignes of inventories have been made in 1985, 1993, 1995, 2000, 2004, 2007, 2008, 2010. The bounding box of this metadata sheet represents only the extension of Parare plots.

The Paracou Research Station encompasses 5000 ha of tropical rain forest near Sinnamary, French Guiana, and is accessible by paved road. The site includes several types of forest plots, each with unique research objectives. Logging Plots: Fifteen nine-hectare plots (numberred 1 to 15) were established in 1984 to study the impact of different logging treatments on tropical tree population structure. This zone is reserved exclusively for studies investigating the impact of the different logging treatments on forest populations. Primary Forest Plot: A 25 hectare plot (no. 16) was established in 1991 for studies of undisturbed forest. Researchers whose interests are unrelated to the effects of logging treatments are encouraged to conduct their work in this plot. Clearcut Plot: a 6.25 ha plot (no. 17) was established in 1989 at a nearby reserve along the road to St. Elie to study the effects of clearcutting on tropical forest dynamics

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Paracou covers a 130,5ha area. It is composed of 16 plots, managed by CIRAD. 114373 trees are being followed since 1984. 30 campaignes of inventories have been made : every year since 1984.
