In the region of Knehyne-Velka Stolova in the Moravian-Silesian Beskids, where there are ecologically difficult conditions for functioning forest ecosystems, possibilities were studied for the naturat regeneration of beech. The study of problems was particularly related to generative propagation, however, cases of vegetative propagation were also found. Potential possibilities of regeneration are related to the seed year 1995. Rooting ability of layered branches or lying beech trees wes studied. Analysis is given of a rooting beech branch.

Surface liming even in higher doses did not affected soil Ph and improving the content of Mg and Ca was only temporary. Spot fertilization by fine-ground amphibolite is significant particularly from the aspect of long-term affects. Short-term affects manifested themselves slightly but in the whole system of particular parameters. Application of higher amounts (3 kg.ha-1) of amphibolite has its substantiation in the future.

Hadas, P. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic))
According to the geostatistical methods annual sums of precipitation, mean annual concentrations of SO2, total potential deposition of sulphur as inputs to the mountain forest ecosystem of Moravian-Silesian Beskids on the spatial level in 1996 were derived. For this purpose, all possible meteorological and monitoring stations in the surroundings of the cesearch teiritory were used.

The planned supraregional biocentre (SRBC) is a support to the system of landscape ecological stability. The sense of this long-term complex project consists in learning features of the ecotope and dynamics of the forest in its present natural and cultural forms and in all existing stages. A draft management plan will be worked out on this basis for the planned SRBC forest area of 1000 hectares, focused on the dynamic ecological stability.
