Abstract
Na območju Šumka % Trstelj je bilo leta 2006 v požaru zajetih 720 ha gozda, od tega je 75 % gozda zajel vršni požar. V zadnjih letih se uveljavlja izkoriščanje sečnih ostankov za sekance, kar vodi v osiromašenje tal z organskimi snovmi. Raziskovalni objekt se nahaja v Kraškem gozdnogospodarskem območju na rastišču jesenske vilovine s črnim gabrom (Seslerio-Ostryetum), kjer je bilo postavljenih 12 večjih raziskovalnih ploskev, porazdeljenih po tri na štirih različnih lokacijah požarišča glede na način izvedbe sanacije. Ugotovili smo, da je bil vpliv rastiščnih, edafskih in reliefnih dejavnikov na uspešnost naravne in umetne obnove mnogo večji kot sam način izvedbe sanacije v posameznem stratumu. Odkrili smo tudi, da je bila uspešnost naravne obnove zadovoljiva v nasprotju z umetno obnovo, kjer je bilo mladje zelo redko. Glede na naše ugotovitve sklepamo, da bodo na teh ploskvah v prihodnosti prevladovali mešani sestoji termofilnih listavcev, predvsem črni gaber, hrasti in mali jesen, ki se jim bosta na boljših rastiščih pridružila v skupinah poljski brest in posamezno gorski javor. Tem avtohtonim vrstam bo ostajala primešana robinija, ki pa ji v primerjavi z avtohtonimi vrstami življenjska moč močno pojema.

Title:Comparison of different types of reconstructions of burnt forest in the area ʺTrstelj - Šumkaʺ
Abstract:
In the area Šumka % Trstelj in the year 2006 the fire covered 720 ha of the forest, of which 75% was crown fire. In recent years, exploitation of logging residues for wood chips is applied, which leads to the impoverishment of the soil with organic matter. The research facility is located in the Kras forest management area, at the site of the autumn moor grass (Sesleria autumnalis) and black hornbeam (Seslerio-Ostryetum), where 12 major research plots were formed. The research plots were separated in 3 groups and set on 4 different locations of the burnt area, depending on the mode of salvage logging. The results indicated that site, edaphic and relief factors had a greater impact on the performance of natural and artificial regeneration, as the mode of salvage logging in each stratum itself. The effectiveness of the natural regeneration was satisfactory in contrast to the artificial regeneration, where the number of seedlings was low. According to our findings, we expect that in the future, the plots will be dominated by mixed stands of thermophilic deciduous species, mainly hornbeam, oak and flowering ash. In the future, they will be joined on better sites by groups of field elm and individually sycamore. This native species will remain being mixed with black locust, whose vitality is in comparison with native species, decreasing.
