Virgin forests are considered valuable reference areas for studying forest ecosystem structures and functions as they have been naturally grown with no human interventions. In the Mediterranean region there are few such areas and even scarcer data on deadwood which is a key element for multi-functional forest management. Data regarding the amount and variety of standing and lying deadwood were recorded in the core zones of the Frakto virgin forest in the central Rodopi Mountains in eight square plots of 0.25 ha each. The average deadwood volume accounted for 175.71 m3 ha-1 with lying deadwood consisting mainly of conifers and representing over 60% of the total deadwood. The deadwood distribution showed a decreasing trend towards larger size classes while in terms of quality deadwood it was represented by all stages of decay, thus showing high variability. The research outcomes contribute to knowledge standards when adopting management regimes in mixed beech forests aiming at sustainable forest ecosystem management.
