No under-storey plants inventory. Soils have been described using 5 samples (1.20m depth max.). No laboratory analysis available for soils.

Guyadiv is a network of permanent forest plots installed over the years in French Guiana. In these plots, all trees above 10 cm dbh are identified, measured and mapped. Several plots are part of permanent research stations (Paracou, Nouragues, Piste Saint Elie). The diversity of arborescent species flora is studied (floristic list). This flora diversity depends on the forest vegetation (architecture, structure, biomass, dynamic in the long term,…

The site Aimara is composed of four 3km-transects (20m wide). 4568 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. 534 under-storey plants have been recorded on 21 25m²-plots by Institut de recherche pour le développement (IRD). Soils have been described using 19 samples (1.20m depth max.). Laboratory…

Guyadiv is a network of permanent forest plots installed in French Guiana. The Guyadiv plan in Crique Plomb and Montagne Plomb sites implements several types of plots and sampling methods: A first group of plots belongs to the Paget's plan, initiated in 1998. These 30x40m-plots are used for floristic and structural inventories.Then, 8 1ha-plots are used for floristic inventories concerning trees with DBH>10cm, since 2002 (campaigns in…

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Matiti have been set up by Marie-Françoise Prévost and Pierre Grenand. It is composed of one 20x4000m-plot. An incomplete inventory has been made on the pool of trees with dbh>=10cm in 2001 : 497 trees have been registrated. 442 species have been identified and 88,9% of the registrated trees have been identified to the species level. We only have the point…

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Haute Beiman is composed of two 1ha-plots. A complete inventory of the trees has been made in 2012. 645 and 507 trees with dbh>=10cm have been registrated, respectively to each plot. 613 and 465 species have been identified. 95% of the trees in the first plot have been identified to the species level, and 91.7% in the second plot. We only have the point…

This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 78 255 ha. 47 205 trees have been inventoried in 317 plots (152 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…
