Badín and additional 23.75 hectares are protected as a buffer zone. Dominant tree species are fir ("Abies alba"), beech ("Fagus sylvatica"), maple ("Acer pseudoplatanus"), ash ("Fraxinus excelsior"), and elm ("Ulmus glabra"). On average, fir threes achieve an age of 350–400 years and beech trees 210–230 years in Badínsky prales. The biggest living fir tree is 46 m tall with a stem diameter of 148 cm. Several dead trees that have already fallen down are even bigger. The local fauna, still partially unexplored, includes red deer, roe deer, boar, brown bear, lynx, wild cat, fox, and marten.
