La cartographie des zones humides du littoral guyanais a été réalisée en 1999 dans la perspective d’un développement durable d’activités de carrières.

Il s'agit des périmètres des Zones d'Activités Economiques guyanaises recensées en 1999 par l'AUDeG. Les périmètres ont été définis à partir des zones à vocation artisanale et industrielle des documents d'urbanisme approuvés ou en cours d'étude et des fichiers du cadastre.

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 investigating the impact of the different logging treatments on forest populations. Primary Forest Plot: A 25 hectare plot (no. 16) was established in 1991 for studies of undisturbed forest. Researchers whose interests are unrelated to the effects of logging treatments are encouraged to conduct their work in this plot. Clearcut Plot: a 6.25 ha plot (no. 17) was established in 1989 at a nearby reserve along the road to St. Elie to study the effects of clearcutting on tropical forest dynamics
