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.

The site Mont Inery is composed of two 3km-transects (20m wide). 1969 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 5 samples (1.20m depth max.). No laboratory analysis available for soils.

The site Montagne Tortue is composed of one 3km-transects (20m wide). 940 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 7 samples (1.20m depth max.). No laboratory analysis available for soils.

The site Montagne Maripa is composed of one 3km-transects (20m wide). 960 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories. No under-storey plants inventory. No soils have been sampled on this site. No laboratory analysis available for soils.

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.

The site Manaré is composed of three 3km-transects (20m wide). 3401 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 2 samples (1.20m depth max.). No laboratory analysis available for soils.

The site Crique Grillon is composed of two 3km-transects (20m wide). 1959 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 8 samples (1.20m depth max.). No laboratory analysis available for soils.

The site Centre Spatial Guyanais (CSG) is composed of four 3km-transects (20m wide). 5007 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 plants inventory available. Soils have been described using 21 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...).

The site Limonade is composed of three 3km-transects (20m wide). 3354 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 16 samples (1.20m depth max.). No laboratory analysis available for soils.
