Ohrožení a ochrana obratlovců (Vertebrata) ve fragmentované krajině (Jablunkovsko)

Abstract

The main goal of this thesis is to clarify the issue of fragmentation of the landscape as the main result of the barrier effect of roads at Jablunkovsko. Highways, high-speed roads as well as lower class roads are creating a barrier in the country which organisms cannot always overcome. The study focuses on this issue and presents possible solutions focused mainly on the technical requirements of migration objects. On a practical example of the migration corridor „Jablunkov“ is verified the function of the landscape and examined the intensity of its permeability for each species of vertebrates (Vertebrata). At the same time are discussed the major negations of the culvert along with possible solutions. Finally the thesis presents an evaluation of the mortality of animals on the II. class road.
