Wpływ terminu i sposobu wycinania brzozy brodawkowatej na jej regenerację i wzrost w uprawie dębowej Effect of time and cleaning method on silver birch sprouting ability and growth in oak young growth
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.
