Plot’s description
Proposition
Damages on Ducamp’s plot
Damages and area 40-60 / 0.45 ha
60 and + / 3.97 ha Biodiversity / 0.13 ha
Ducamp’s plot description
Naturel regeneration of Pinus Pinaster Zone of Quercus Robur Quercus Robur little present
Proposition
• Harvest Pinus Pinaster (and keep Quercus Robur)
• Plantation of Pinus Pinaster
Biomass / semi-specialized stand
• Density: 2 500 t/ha (2 X normal density)
• Harvest at 7 years of 1 250 t/ha
• After normal running

Games damages
-To privilege other hardwood of natural regeneration
-To chose a vigorous species
-Important games damages, avoid to plant Malus Sylvestris
Conclusion
Biodiversity + production
-To change the mentality in te wood production
-Respect to the environnemental regulation
-To increase the biological diversity
-To incorporate hardwood area
-To choose the best system for the Biomass
-To improve plantation’s system for the border hardwood
Finally, it’s possible!
