Abstract: MCPFE recognized dead wood as an indicator in the assessment of the biodiversity and naturalness of forests ecosystems. Dead wood could play an important role in limiting atmospheric CO2 levels too. Investigations have been carried out in unmanaged Fagus sylvatica and Quercus frainetto stands in three protected areas (Aspromonte National Park, Serre Regional Park and Pollino National Park) in southern Italy. In this context, dead wood is divided into: coarse woody debris (CWD), standing dead tress (SDT), litter, stumps and root biomass. The aim of this work was to produce data about the quantities and the quality of dead wood. The average volume of CWD is 4.5 m3 ha-1 in beech forest and 23.3 m3 ha-1 in Quercus frainetto stands. The average volume of SDT is 4.8 m3 ha-1 in beech forest and 4.7 m3 ha-1 in Quercus frainetto stands. Average total litter production is 4.9 Mg ha-1 in beech forest and 4.6 Mg ha-1 in Quercus frainetto stands. Stumps volume is, respectively, of 0.13 and 0.37 m3 ha-1. With regard to root biomass, significant differences in volume between SDT and stumps were recorded. The carbon stored in dead wood is 5.39 Mg C ha-1 in beech forest and 12.8 Mg C ha-1 in Quercus frainetto stands. Old Quercus frainetto trees (diameter > 60 cm) are frequent in the Aspromonte National Park and play an important role in maintaining animal and vegetable biodiversity. Observations on the dead wood management in Fagus sylvatica and Quercus frainetto stands in Mediterranean area are here made.
