Assesment of landscape permeability - example of Prague highway bypass

Permeability of the landscape is crucial for the survival of many species. However, nowadays is quickly increasing the landscape fragmentation and the connectivity of landscape elements is decreasing. Fragmentation of the landscape is mainly affected by road constructions, which cause even other significant ecological impacts. In connection with recovery of the permeability of the landscape are therefore made these line barriers often passable. Construction of the road over- and under- passes is common measure, but the remaining question is if constructions of these objects help to achieve required measures. The practical part of this thesis is therefore focused on analysis of selected passageways of Prague highway bypass and on the evaluation of their using. Keywords: Landscape fragmentation, landscape permability, ecoducts, mitigation measure
