Zagrożone gatunki drzew Białowieskiego Parku Narodowego (Rezerwat Ścisły)

An assessment of the current dynamic status of tree species occurring in the Strict Reserve of the Białowieża National Park is presented. On the basis of long−term trends and analysis of large−scale inventory data, the three major groups of trees are distinguished: 1) ‘safe’ group, containing hornbeam and lime, 2) ‘presently safe, but declining in a long−term run’ group, involving spruce, birch and alder, and 3) ‘threatened and highly threatened’ group, consisting of oak, pine, ash, maple, elm and aspen.
