Guyadiv Crique Plomb and Montagne Plomb: plots of forest inventory since 1998.

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 2002, 2004 and 2005). These plots are located on greatly contrasted forest facies (high-density forest on thinned soils, forest on dismantled ferricrust, forest on deap DVL soils). The third type of sampling method is a "cluster points" (points-grappe) plan for floristic linear inventories. 18 points have been carried out, that is to say almost 8500m or 10ha of statements (ca. 5500 trees). 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 600 meters in each direction.
