Forest

Forests cover two thirds of the park's area including valley bottoms, steep slopes and high plateaus.

The most characteristic tree species in the Triglav National Park are beeches, spruces and larches. Though especially spruces, larches and dwarf pines create the image of the Alpine world, the Julian Alps are also characterised by warmth-loving stands of hornbeams and ashes on the southern side of the park.

Only species and individual trees which adapt to the harsh conditions of the mountainous areas of TNP can thrive. On the Soča side of the park the tree line does not extend above 1600 metres. The highest reaching tree species is the beech, which is comfortable with frequent cloudiness and abundant precipitation, but spruces and larches manage to survive on higher ground. In the centre of the park and in the north, the higher forest belt is dominated by spruces and larches, which set the tree line at 1800 metres.

The Triglav National Park contains forests reserves with a total are of over 1000 hectares, which are completely left to natural development.
