Girdling is a measure where by removing of bark, cambium and few last annual rings, we make competitive ability of tree becoming weak. Purpose of girdling is at belated thinning to preserve stand stability. In the thesis we divided the girdling analysis on two parts. In the first part we analysed existential objects with girdled trees in 8 locations in forest management units Gornja Radgona and Ljutomer. On each tree we measured and defined thoracic diameter, approximate height of girdling from the ground, length of girdled section, length of crown, fall off of crown in percentage (%), tool with which they executed girdling and execution time. In the second part we executed the time comparison between girdling and felling by chain saw on 50 areas of dimension 7x7 m. We tested 5 methods with girdling by hatchet: girdling at 0,5 m of height, girdling at 1 m of height, girdling at 1,5 m of height and method girdled at 0,5 m and 1 m of height where bottom part of bark is tearing apart from trunk of tree. Among tree genus greatest regenerative ability indicated beech and ordinary white beech (hornbeam), when the least regenerative abilitymanifested non-indigenous robinia, linden and trembling tree. Greatest influence on dying away speed besides tree genus also has the time past from girdling. At the same thoracic diameter the classical felling is more favourable considering time up to thickness of 9 mm. Above this thickness, from point of view of expenses it is better to perform girdling. Between individual girdling methods we found out distinctive difference considering use of time between girdling method at 1 m of height and the girdling method at 0,5 m where bottom part of bark is tearing apart from trunk of tree. On thebasis of our researches and experiences we suggest prosecution of girdling in seedling only at points and combined with classical tree felling.
