  • This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 73 113 ha. 44 091 trees have been inventoried in 288 plots (140 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...).

  • The “Inventaire Papetier” was conducted by the CTFT (Centre Technique Forestier Tropical became CIRAD in 1984) and ONF between 1972 and 1976. To assess the forest resources in French Guiana, the forest was divided in large blocks along the coast (4 blocks near St Laurent, 4 blocks near Kourou and Sinnamary, 6 southern of Cayenne). Within the blocks, the forest was inventoried in 25*200m plots placed every 200-400m on parallel lines separated by 1 to 3km. The DBH was measured in 10cm classes, starting at 10cm, 15cm, or 20cm.
