Stojecova I. Kupka Faculty of Forestry and Wood Sciences Czech University of Life Sciences in Prague Prague Czech Republic ABSTRACT Wild cherry is one of the noble hardwood species that increase the biodiversity of our forests and at the same time it could increase the income for forest owners. The preconditions for achieving these goals are the high quality of stem and appropriate silvicultural management. This means that wild cherry should occupy the main crown layer in the stand. The height frequency diagram depicts two groups of wild cherry trees in the stand belonging to dominant codominant and suppressed tree classes. Height periodic increment measured between the years 2001 and 2007 is significantly p different in these two groups confirming that there is no transition chance for the trees from the suppressed group to become a part of the main crown layer and play the role of future crop tree. The same is true of the diameter frequency diagram which also has a two-peak shape remaining also at the end of the surveyed period. Our result suggests that silvicultural care should be focused only on trees belonging to future crop trees. Keywords wild cherry silviculture stand forming species stand crown layer tree classes Actual silvicultural and management regimes should ensure the sustainability of forest ecosystems in terms of production their diversity and other goals expected by modern society. Species which fulfil these goals are in focus of modern silviculture. One of these species is wild cherry Prunus avium L. and that is why it is also a subject of research. The wild cherry has its optimum in the first to the fourth fifth forest vegetation zone Cizkova Bendíková 1999 Skvareninová Skvarenina 2005 in a rich and floodplain forest. It shows the best growth performance on fresh nutritious loamy and calcareous soils
