GUYAFOR: a network of research permanent plots
of tropical forests in French Guiana
GUYAFOR is dedicated to long-term studies in forest dynamics and biodiversity to provide a scientific basis
for the sustainable management of forest resources. Forest plots have been established in French Guiana since the late 60's. They have been recently integrated into the GUYAFOR network with standardized protocols for both tree inventories and environmental characterization.

Data base management tools
FOREST PERMANENT PLOTS
To understand forest structure and floristic composition across gradients of soil type and precipitation
To understand long-term forest dynamics in mature and logged forests:
the role of demographic processes (growth, mortality, regeneration)
biomass dynamics and carbon cycling the consequences of climate change
