Sixteen forest reserves are situated in the northern part of Hungary
which belongs to the Carpathian region according to EURAC delimitation (Ruffini
et al.2006). These Hungarian forest reserves expand the natural forest remnant/
forest reserve net of the Carpathians towards the lower hilly region, representing
the deciduous beech and oak forest belts near their lower (xeric) distribution limits.
This paper outlines the Hungarian forest reserves belonging to the Carpathian
region and the preliminary results of current projects in the Vár-hegy Forest
Reserve (Bükk Mts., Hungary) as a case study. The alteration of tree species
composition was investigated here based on the reconstruction of forest history in
the previous 130 years (management period) and analyses of forest stand inven-tory. In another project CO2 sequestration changes of these forest stands were
modeled since the clear-cutting in the 1880th and carbon stored in the forest
ecosystem compartments was estimated. Our results show that the forest reserve
stands are presently in a transition state from the managed forest towards a more
natural mixed forest with several age-classes.
