Forest Reserve Virgin Forest Krokar is located in a vast forest area of over 90,000 hectares with sustainable close-to-nature forestry. Two peaks and a karst plateau with deep sinkholes and steep slopes characterise the area within the Dinaric Alps in southern Slovenia. It is assumed that the beech found refuge here during the ice age and was subsequently able to spread out from here again. Beech and fir define the scenery of this picturesque wilderness, which is home to an original fauna. Other plant species survived the glacial periods here and are endemic today. The wild woodlands provide an impression of what European beech forests can become in the course of the ongoing ecological process.
