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…

The site Itoupé is composed of 6 3km-transects (20m wide). 5516 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). Fauna inventories are available on this site. 834 under-storey plants have been recorded on 35 25m²-plots. Soils have been described using 28 samples (1.20m depth max.). Laboratory analysis are available for two soil profiles.

Guyafor is a network of permanent forest plots installed in French Guiana. The site of Risquetout covers a 23,7ha area. It is composed of 4 plots managed by ONF. 7174 trees are being followed since 1995. 9 campaignes of inventories have been made in 1995, 1999, 2001, 2002, 2003, 2004, 2006, 2008, 2009.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site Piton de l'Armontabo is composed of one 1ha-plot. A complete inventory of this plot has been made in 2006 : 538 trees with dbh>=10cm have been registrated and 533 species have been identified. 99,1% 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 plot. In…

This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 18 737 ha. 17 560 trees have been inventoried in 80 plots (40 ha). Pre-census DBH is 10 cm on all plot. DBH have been measured by classes with a range of 10 cm. Plots have been located on GIS in 2006 using original maps and field note-books (indicating slopes, rivers, etc...).

The aerial laser scanning (ALS) dataset acquired on 26th September 2011 covers part of the Paracou experimental station in French Guiana. Plots entirely covered include Paracou 4, 5, 7, 8, 9, 10, 11, 12, and 14. Plots 3, 6, 13, and 15 are partially covered by the data. The area includes both natural unlogged forest and logged over forest.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Petite Montagne Tortues is composed of 7 plots : 5 30x40m-plots and 2 20x20m-plots. A complete inventory has been made in 2005 : 483 trees with dbh>=10cm have been registrated. Respectively to each plot, 67, 70, 79, 49, 22, 57 and 80 species have been identified. The percents of trees identified to the species level are 95,7%, 79,5%, 95,2%, 92,5% 62,9%, 91…
