Tree harvesting in OPTMix experimental plots is now completed (related articles here and here). Most of the exploitation was performed in one month (from 2017-09-25 to 2017-11-03) and was realized in very good conditions.
A big thank you to the National Forest Office (ONF) who carried out and coordinated this operation and who was able to find solutions to take into account all the constraints of this experimental device.
