Srovnání hodnot stability stromu zjištěných různými přístrojovými metodami

The thesis is focused on the comparison of tree stability values and break resistance of stem against fracture using various instrumental methods. The accuracy and suitability of individual methods is discussed in the literature review. At the selected locality, the trees were visually evaluated and subsequently the break resistance of stem was measured. The methods used were acoustic tomography and pulling test. The basic value of the stability of a healthy tree under wind load and the stability value with respect to stem damage by defect or rotting are compared
