    Opis:
    The objective of the study was to examine the sprouting ability and growth of silver birch after cleaning in a 11−year−old oak stand in Kolumna Forest District (central Poland). The purpose of the cleaning was to remove naturally regenerated birch. Six different treatments were applied as a cleaning methods. They differed in time of application and height of cutting or breaking the birch sprouts, i.e. spring cleaning at ground level in every second oak row (W1) or over the entire surface (W2), cutting or breaking at a height of 1 m in spring (W3a, W3b) and cutting or breaking at a height of 1 m in summer (W4a, W4b). We analyzed the formation of new sprouts and their height and dbh increment over a 4−year period after the treatment. On average, after spring cleaning 10−20% of birches produced new sprouts when birch was cut at the ground level. When cut at one meter, 85−90% of birches produced new sprouts. Cleaning in the summer decreased the sprouting ability by 20−25%. There were also significant differences in height growth of sprout between spring (better) and summer (worse) time of cleaning. There were no significant differences in sprouting ability and sprout growth between cutting and breaking when done at the same time of the year. Thus, the most effective way to restrict competition of birch in young oak stands is cutting at ground level.

    Opis:
    Naturally regenerated silver birch is one of the most abundant competitor for planted seedlings in central Poland. The effect of the interaction between planted oak seedlings and naturally regenerated birch was studied in 14−17−years−old sessile oak stand. The experiment was established at stand age of 14−years. At that time, there were around 4000 oaks and 10000 birches per hectare. A sample of dominant individuals of oak were selected and one of three treatments were applied to each individual. The treatments included: (i) removal of all naturally regenerated trees in a radius of 1 m (W1), (ii) removal of all naturally regenerated trees in a radius of 2 m (W2) and (iii) untreated control (K). Breast height diameter and height of selected oaks were measured during three years following the experiment establishment. The release of competition resulted in greater diameter and height growth. The diameter growth was increasing with an increment of free space from oak and was the greatest in the W2 treatment. The increment of height growth was similar regardless of the treatment radius. In practical forestry, silver birch can be recommended as admixture in pure oak stands with low survival rate as replacement for dead oaks. However, a minimum distance of 2 m between oak and birch should be kept.

    Opis:
    We examined growth of oaks after cleaning carried out in a 11−year−old stand in Kolumna Forest District (central Poland). The purpose of the treatment was to remove naturally regenerated species mainly birch. Four different cleaning variants were applied. They differed in time of application and height of unwanted trees i.e. spring cleaning at ground level in every second oak row (W1) or over the entire surface (W2), breaking at a height of 1 m in spring (W3) or in summer (W4) and control (K) where trees were not removed. We analyzed height and its increment, dbh and its increment as well as slenderness, i.e. h:d ratio, in 4−year−long period after treatment. The study reviled that the cleaning, regardless of the applied method, significantly improved oak growth, while lack of cleaning led to increased competition of birch. The pressure from the other species firstly reduced diameter increment and later the height increment (tab.). As a result, the h:d ratio of oaks increased. The 4−year height and dbh increment were similar in all the applied treatments but in the last year of study the dbh increment in variants W2 and W4 was significantly higher than in W1 and W3 due to greater competition of birch in these variants (figs. 1 and 2). Cleaning done on a limited area provides satisfactory growth and stability for young oaks, but it is probable that such a stand needs more frequent intervention than the one from W2 cleaning variant.
