At present forest on the territory of Great Dnister bogs
occurs as not very big and separated fragments. It was been shown the forests
an antropogenically changed alder thickets wich are derivative from association
of Ribo nigri – Alnetum. Comparison of species composition of this association
on the Great Dnister bogs and on the territory of reserve „Roztocha” shows that
species-composition on the bogs are poorer. We can find the explanation of this
matter in conditions of it’s forming and existence or it’s development.
