SUMMARY<br />
Investigations on the influence of stand teendirtg on<br />
the production and quality of Sessile Oak coppice forests<br />
In the SR of Bosnia and Hercegovina there exist considerable areas of former<br />
scrubs of Sessile Oak in which, 15—20 years ago, were sporadically performed<br />
improvement interventions by cleaning, so that today they correspond to<br />
coppice forests. Cleanings were performed by thinning stool^shoots. For the purpose<br />
of determining the influence of stand tending on the production of volume<br />
and its quality by the method of intensive thinning, the author has laid out an<br />
experimental plot in the management unit of Kruščica (Lašva forest region).<br />
In the paper are set out data on the condition of the stand before the thinning<br />
and on the intensity of the intervention performed.<br />
Data on the condition of the stand on the experimental plot before and<br />
after intervention are presented in Graphs 2—5. In these graphs the 1st group<br />
of columns refers to the control subplot, 2nd group to subplot I or subplot of<br />
a more intensive selective thinning (17.7 °/o by stem number and 26.8 °/» by volume),<br />
while the 3rd group refers to subplot II or the subplot of weaker thinning<br />
(7.4 u /o by stem number and 11.4%» by volume). In Graphs 2—4 'the entire<br />
height indicates the total amount removed, while the hatched area designates<br />
the removal by thinning, i. e. Graph 2 — stem distribution, Graph 3 — removal<br />
by basal area, Graph 4 — removal by volume.<br />
In Graph 5 is presented the quality of the stems, i. e., under A — upper<br />
storey, B — middle storey, C — lower storey, and D — total; horizontally hatched<br />
area — good stem quality, vertically hatched area — medium stem quality, and<br />
slanted hatched area — poor stem quality; I — before thinning, and II — after<br />
thinning.<br />
