Guyadiv: a forest inventories network in French Guiana since 1986

Installations de suivi environnemental
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,…

Guyafor: permanent plots of forest inventories in French Guiana since 1968

Installations de suivi environnemental
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…

Guyaflux: a micrometeorological tower for studying greenhouse gases exchanges between the guianese amazonian forest and atmosphere since 2003

Installations de suivi environnemental
The experimental site of Guyaflux in the Paracou forest (Sinnamary, French Guiana) has been created in 2003 and is set up for at least 20 years. Guyaflux has several aims : 1. to characterise the greenhouse gases exchanges between the forest ecosystem and the atmosphere. 2. to assess the contribution of Guianese tropical humid forest ecosystem to the biospheric carbon sink. 3. to assess the impact of environmental constraints on carbon…

The Nouragues forestry experimental site: permanent plots of forest inventories since 1985.

Installations de suivi environnemental
The Nouragues forestry experimental site is located the Nouragues experimental station in French Guiana (other experimental sites than Nouragues plots are established in Nouragues station). This experimental site is composed by several plots not contiguous, some of them are divided into smaller plots (1ha). For each plot, the following information is recorded for all trees and lianas with DBH ≥ 10cm : 1. location of individuals inside the plot…

Worldwide Reference System (WRS-1 and -2) used in cataloging Landsat data.

Systèmes de maillage géographique
The Worldwide Reference System (WRS) is a global notation used in cataloging Landsat data. Landsat 8, Landsat 7 follow the WRS-2, as did Landsat 5. Landsat 4, Landsat 3, Landsat 2, and Landsat 1 followed WRS-1. The shapefile holds the bounding box coordinates.

Bridge: plots of old-growth forest to gather information on tree diversity and to test ecological theories in French Guiana since 2007.

Installations de suivi environnemental
The project Bridging Information on Tree Diversity in French Guiana, and a Test of Ecological Theories (BRIDGE) brings together researchers from nine different European research groups in tropical ecology, and seeks to improve our knowledge on the various dimensions of tree biological diversity in French Guiana. The project includes ten one-hectare old-growth forest tree plots across a range of geology and rainfall in French Guiana. The amount…

Guyadiv Piste Saint Elie: plots of forest inventory since 1986.

Installations de suivi environnemental
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.…

The Paracou forestry experimental site: permanent plots of forest inventories since 1984.

Installations de suivi environnemental
The Paracou Research Station encompasses 5000 ha of tropical rain forest near Sinnamary, French Guiana, and is accessible by paved road. The site includes several types of forest plots, each with unique research objectives. Logging Plots: Fifteen nine-hectare plots (numberred 1 to 15) were established in 1984 to study the impact of different logging treatments on tropical tree population structure. This zone is reserved exclusively for studies…
