The paper presents the results of a naturalness assessments, and also of the first inventory in two newly established forest reserves (Voievodeasa and Loben) from North of Romanian Eastern Carpathians. The evaluation of naturalness used the historical data concerning the wood extraction, as were recorded in the forest management plans. In selected stands of higher local naturalness was further conducted an inventory, following the methodology recommended by COST E4 and based on a systematic grid with circular plots of 500 m2 . Expected, the results showed that extraction impacted the structural characteristics of stands, esspecially the standing/downing trees volume. The comparison of structural data resulted from inventory (density and volume of both alive and dead standing trees and coarse woody debris) with local references - “virgin“ forests located about 40 km apart of the forest reserves under study - suggested a degree of correspondence between 20-40%. The same data, compared with published information available from mixed forest of beech-fir-spruce accross temperate zone of Europe confirmed the departure of selected stands from the references of naturalness and their distinct grouping, compared with other forest reserves.
