- Abstract
The concepts regarding the presence and the usefulness of the dead wood, both standing dead trees and logs fallen on the forest ground, have changed lately. If in the past the presence of dead wood in the forest was considered as an indicator of inadequate management of the stands, nowadays it is believed that the existence of dead forest trees is of great importance both in terms of biodiversity conservation and its role as renewable energy resource, as well as for maintaining soil fertility. Therefore, this paper presents the results of research undertaken in the natural beech forests from the "lzvoarele Nerei" reserve concerning the situation and dynamics of dead wood from these forests and its importance for biodiversity conservation. The paper shows that the volume of dead wood (standing snags or logs fallen on the ground) from the unevenaged natural beech forests varies by altitude between 50 and 223 m3 per hectare, with an average 87 m3/ha. The largest values were recorded at 1,000 m altitude, where the vegetation conditions are optimal for the beech species, and the lowest values were found at 1,350 m altitude; the largest share of dead wood is represented by the fallen trunks on the ground. The dead wood volume from the natural beech forests far exceeds the limit of 15 - 20 m3/ha, considered by entomologists and phytopathologists as the minimum amount needed for biodiversity conservation of insects and mushrooms.
