Stabilnost gozdnih površin v Sloveniji kot kriterij krajinske pestrosti in obstojnosti

The stability of forest core areas is an important indicator of biotic diversity on a landscape level in the process of deciding whether certain forests could be cleared. Consequently, we decided to estimate the stability of forest core areas in Slovenia between 1975 and 2012, as we are in...
