Guyadiv Paracou: plots of forest inventories in Paracou experimental station since 1986

Guyadiv is a network of forest inventory plots installed in French Guiana. In Paracou experimental station 2 sets of plots pertain to the Guyadiv network Transects (> 2cm dbh) Ten 20x250m-transects have been inventoried within ten larger experimental plots. In those plots all stems > 2cm dbh have been censused (mapped and identified to species level). Plots were measured twice (once between 1994-1998, and once in 2002) 3 transects in plots subjected to treatment 1 (commercial logging only, of trees of DBH>50cm between 1986 and 1988, on average 10 stems per ha) 3 transects in plots subjected to treatment 2 (commercial logging as treatment 1 + thinning by poison-girdling of all non-commercial species of DBH≥40cm between 1986 and 1988) 3 transects in control plots (without treatments) 1 transect in plots subjected to treatment 3 (commercial logging + logging for fuelwood of all non-commercial treed of DBH between 40 and 50 cm + thinning of trees of more than 50cm DBH between 1986 and 1988) In addition 10 0.5 ha plots within the Guyaflux foot print have been set-up in which all trees > 10cm dbh have been inventoried.

Statement
1. We have received for the Guyadiv Paroucou site one shapefile that represents the delimitation of the GuyaFor plots, the GuyaDiv transects and the GuyaFlux plots. Another shapefile that represents the demarcation of Paroucou site in the GuyaFor network was also available. We have a shift of around 10 meters in x and y if we compare the demarcation of the Paroucou plots in the two shapefiles. 2. We finally used the demarcation of Paroucou from the GuyaFor network as reference information for this dataset. We included the original GuyaDiv shapefile as an additional information into the downloadable zip file.
