Abstract

We studied soil conditions and floristic comsposition in the forest of beech and Hairy Alpenrose (Rhododendro hirsuti-Fagetum) and in the south-Alpine Austrian black pine forest (Fraxino orni-Pinetum nigrae) within the area of the forest fire in Govci (which is located in the northwestern edge of the Trnovski gozd plateau, western Slovenia) and compared them with conditions in preserved beech and black pine forests five years after the wildfire. The black pine forest overgrows Lithosols and Moder Rendzinas. In the beech forest beside these soils, more-developed Mull Rendzinas and Brown Rendzinas have evolved as well. On the scene of forest fire fertility, thickness and areal shares of soils were greatly reduced and surface stoniness with rockiness proved to be increased. Vegetation of the burnt forests differs from preserved forests mostly in the abundant appearance of some species characteristic for forest clearings and burnt sites (class Epilobietea angustifolii). In the moss layer species Ceratodon purpureus, Polytrichum juniperinum and Marchantia polymorpha are typical for places of the fire (the last two especially for the burnt beech forest).
