Habitats inventories have been installed over the years in French Guiana using a standardized multi-scale protocol. In each site, we established two to four transects, about 2.5 to 3-km long in different directions to optimally sample the local environmental variability. Each 20-m width transect was divided into 100 m segments so that the basic sampling units are 0.2-ha plots. All the plots were geo-referenced using a Garmin 76CSx GPS receiver…
