Natural forests are characterized by diverse structural complexity. Homogeneous forest with one dominating tree of the same age usually lacks small sunny glades, different kinds of cavities, hollows on the trees, or e.g. decaying dead wood in a stream. Therefore, in the sessile oak dominated forests of Nagyoroszi and Diósjenő, we restored the natural forest structure where these elements can be found or will be able to develop.
By doing this we moved all together approx. 400 m3 of wood in Nagyoroszi and 260 m3 of wood in Diósjenő, which is about 10 % of the forest stock. Depending on local conditions and needs we felled down a tree to create a small leak (10-15 m2) to allow little light to penetrate through the closed canopy. Depending on local conditions in other cases we created larger glades (20-150 m2), thus we created e.g. spaces for the wild blackberry, strawberry and rosehip. Furthermore, the reconstruction of the natural forest structure also meant that we felled down few of the trees which are abundant and dense to assist suppressed or rare trees such as wild cherry, goat willow or wild service tree. We also created decaying and dead wood by barking the trees to favor birds, saproxylophagous beetles by providing living and feeding places. Thus we not only enriched the structural elements of the forest but provided space for the diversity of life to survive and flourish.
