The Survival and Growth Rates of Woody Vegetation in the Man-Made Vracov Biocorridor During the Period of 1993-2007

The first biocorridors were established in the territory of the Czech Republic in the nineties of the 20^th century. One of them, planted on a formed agricultural land, was the Vracov biocorridor. This paper deals with the growth and development of trees on two permanent research plots in the period of 1993 to 2007. Repeated inventories of trees as well as monitoring of biometrical parameters were carried out there in both, the tree and shrub layers. The number of trees decreases with the increasing level of stand canopy. Moreover, mean heights and diameters of Quercus robur, Tilia cordata and Cerasus avium were compared. Under the given conditions, the growth of these tree species can be positively evaluated.
