Il ceduo oggi: quale gestione oltre le definizioni?

摘要: Abstract: The economical-social change, the competitiveness and “modernity” of fossil fuels, their prompt diffusion are concurrent factors that heavily reduced use coppice firewood charcoal since fifties last century. Therefore, a shift took place in 60 years from homogeneous area made intensively managed, young stands to more differentiated standing crops, as for structural features, growing stocks growth dynamics, even though all them originated common matrix. Nowadays, former includes managed under lengthened rotations, outgrown coppices, conversion into high forest. 2005 National Forest Inventory reported 87% crops was included age-classes 20-40 over 40 years, with variable percentages according tree species, beech up thermophilous oaks. Here, basis historical judgment on system, reasons underlying establishment, current standards cultivation doubled critically analyzed. demand reduce fuels by renewable bio-energy sources face effects climate change (unpredictability, rainfall reduction, higher air temperature, prolonged droughts, water stress, fire risk) give new boost system. Main goals today to: (i) optimize capacity production heavy deficit at country level; (ii) make best regeneration ability inherent system against sensitive seed changing environment. positive trend, maintenance resprouting well vital stools density area, address sustainable increase rotations age 50 already highlighted few regional regulations. It would allow recovery volume increment 1-1.5 M m3 internal production. Unsuitable stand locations or bio-ecological conditions forest obviously excluded. approach within territorial context, possible innovation definition flexible silvicultural models then outlined. useful updating harmonization regulations finally recalled.
