The aerial laser scanning (ALS) dataset, acquired in October 2004, covers five plots of Crique Plomb and Montagne Plomb area in French Guiana. In this area. the forest presents contrasting and diversified characteristics : high forest, forest grown on ferricrust, and superficial saprolit with high density of stem per hectare. Ground echoes are available as well as a digital terrain model (DTM), a digital surface model (DSM), and a digital canopy model (DCM) with a 1 meter resolution.

The aerial laser scanning (ALS) dataset, acquired between 8 and 9 April 2009, covers five plots of Crique Plomb and Montagne Plomb area in French Guiana. In this area. the forest presents contrasting and diversified characteristics: high forest, forest grown on ferricrust, and superficial saprolit with high density of stem per hectare. Ground echoes are available as well as a digital terrain model (DTM), a digital surface model (DSM), a digital canopy model (DCM) with a 1 meter resolution and a triangulated irregular network (TIN) digital terrain model with a precision of 5 meters.

The site Crique Plomb is composed of three 3km-transects (20m wide). 3998 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories. No under-storey plants inventory. Soils have been described using 10 samples (1.20m depth max.). One laboratory analysis available for soils.

The image covers the experimental sites Counami, Paracou, Piste Saint Elie, Crique Plomb and Montagne Plomb in French Guiana.

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.

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, dynamic after perturbation and biogeography) which is also studied. The contribution of flora diversity to forest vegetation (carbon cycle issue...) is another topic approach in the studies. Analyses are conducted at different spatial scales (local - intra site, regional, subcontinental via ATDN network) and temporal scale (impact of logging, impact of old settlements : COUAC project). We only have the point coordinates and not the precise demarcation for most of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location between 100 and 600 meters in each direction. Information specific of each site (Paracou, Montagne Plomb, Crique Plomb, Piste Saint Elie, Counami...) is available. Please refer to the attached metadata sheets. This network relies greatly on the IRD Herbier de Guyane (CAY) and its network of international specialists.

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 and delineated in the field using a Vertex laser clinometer. In each plot, all trees (including palm-trees) greater than 20 cm diameter at breast height (DBH) or above the buttresses were identified by local forest-plotters from ONF. They referred to a vernacular nomenclature whose names correspond either to a botanical species, genus or family. Tested against true botanical data on 4279 trees (Guitet et al., 2014), this nomenclature proved 83% effective accuracy at the family level and 74% at the level of the most precise botanical equivalent of our vernacular names (i.e. the species, genus or family level depending on the precision reached by forest-plotters). Soil samples were also collected in 490 selected plots representative of the different topographical positions along each transect. Chemical and textural analyses are available. Plants of the under-storey have been collected by IRD in several 5m x 5m sub-plots on different sites : Kourouaï, Piton Baron, Aïmara, Saut Parasol, Mont Itoupé, Waki, Toponowini, Bagote, Haute Beiman, Roche Koutou, Regina. Standardized line transects surveys were conducted by ONCFS in 25 sites on the same transects in order to record large mammals and terrestrial birds. Transects were walked at less than 1 kmh-1 speed every morning (7:00-11:00) and afternoon (14:30-18:00) by only one observer by trail, systematically alternating transects on consecutive days to avoid observer bias. All encounters of focus species and their localization on the trail were systematically recorded and the perpendicular distance between animal and transect was measured with a laser ranger finder to the nearest meter.
