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.
