Biomass availability in forests, poplar plantations and hedges for various timber uses. National assessment based on the national forest inventory data and wood consumption statistics

This article provides an assessment of the quantities of potentially exploitable timber in French forests, poplar plantations and hedges for the period 2007 to 2020. The first step consisted in computing the gross available quantities of timber, prior to deduction of the various current consumptions. This was done applying the reference silvicultural scenarios to all the plots in the French national forest inventory, on the basis of their features (species, structure, fertility, age, observed per hectare volume). Current consumption was then subtracted from these quantities. It was estimated using the annual sectoral 'forest exploitation' survey in industry and an estimation of fuelwood consumption by households. The outcome is an excess availability of more than 28 million cubic metres of timber per year for bio-energy or pulp uses, and nearly 15 million cubic metres of workable timber, essentially hardwoods.
