This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 23 706 ha. 11 427 trees have been inventoried in 97 plots (47 ha) Pre-census DBH is 10 cm on one plot out of 10 and 15 cm in the others. DBH have been measured by classes : 10-20 cm or 15-20 cm for the first class and with a range of 10 cm since 20 cm. Plots have been located on GIS in 2006 using original maps and field note-books (indicating slopes, rivers, etc...).

This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 40 556 ha. 25 735 trees have been inventoried in 169 plots (82 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 2009 using original maps and field note-books (indicating slopes, rivers, etc...).

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).
