  • 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 site Crique Bastien is composed of two 3km-transects (20m wide). 2608 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories available. No under-storey plants inventories are available. Soils have been described using 3 samples (1.20m depth max.). No laboratory analysis available for soils.

  • The site Sables Blancs is composed of two 2.5km-transects (20m wide). 1627 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories. No under-storey plants inventory. No soil sample has been made on this site. No laboratory analysis available for soils.

  • 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...).

  • Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Monts d'Arawa is composed of 2 1ha-plots. A complete inventory has been made in 2006 : 1528 trees have been registrated. 512, 480 and 530 species have been identifies respectively on each plot. The percents of trees identified to the species level are : 99.6%, 99.8%, 99.4% on the 3 plots. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 200 meters in each direction.

  • Guyadiv is a network of permanent forest plots installed in French Guiana. The ONF experimental site of Montagne Tortue is composed of 2 plots : one 1ha-plot and one 110x115m-plot. A complete inventory has been made in 2002 : 982 trees with dbh>=10cm have been registrated. 494 and 476 species have been identified. 98,2% and 99,4% 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 plots. In order to calculate the bounding box for these plots, we have expanded the point location 300 meters in each direction.

  • Guyadiv is a network of permanent forest plots in French Guiana. The experimental site of Piste de St Elie is composed of one 10-ha plot (100 m x 1000 m), an adjacent 2-ha plot (100 m x 200 m), and three distant plots: a 5-ha (100 m x 500 m) and two 1-ha (19 ha total area). These plots are located in the ECEREX area of Piste Saint Elie. The botanists who have set-up the plots and contributed to identification and tree measurements are D. Sabatier, M.-F. Prévost, J.-F. Molino, B. Riéra, E. Fonty and C. Madelaine. During the inventories, the data recorded are: geographical position of the trees, dbh and identification by botanical sampling. On all 19 plots, all trees above10 cm dbh were censused. On a 1-ha plot (20 m x 500 m) nested within the 10-ha plot, all trees above 2 cm dbh were also censused. The first year of inventory of trees with dbh >= 10 cm was 1986, 1987, 1988 or 1991 (depending on the plots), and 1994 for trees with dbh between 2 and 10 cm. A second inventory was conducted in 2003 on the 10-ha plot (including trees with dbh between 2 and 10 cm) and the two distant 1-ha plots.

  • Guyafor is a network of permanent forest plots installed in French Guiana. The Guyafor Database compiles coordinates of the 11 sites (Paracou, Bafog, Organabo, Risquetout, Montagne Tortue, Saut Lavilette, Acarouany (Javouhey), Montagne Plomb, Tibourou, Nouragues, Laussat) and their subdivisions of the guianese permanent plots network. Each site contains georeferenced trees, botanically identified and regularly measured (diameter) for varying periods, depending to the site. To have more informations about each site, please refer to the attached metadata sheets

  • Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Eperon Barré is composed of two plots : one 1ha-plot and one 100x200m-plot. A complete inventory has been made in 2009 and 952 trees with dbh>=10cm have been registrated. 535 and 405 species have been identified in the two plots. 99,1% and 98,3% 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 plots. In order to calculate the bounding box for these plots, we have expanded the point location 500 meters in each direction.

  • Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Savane Roche Virginie is composed of three 1ha-plots. 3 complete inventories have been made in 2006, 2007 and 2008 : 1664 trees with dbh>=10cm have been registrated. 475, 507 and 657 species have been identified respectively to each plot. 97,9%, 99,2% and 98,4% of the inventoried trees have been identified to the species level. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 300 meters in each direction.
