Designing migration corridors for large mammals in the Czech Republic

Abstract

The presented article introduces methods and some results of a project aiming to improve the protection of landscape permeability for migration of large mammals. The main aim of the project was delimitation of migration corridors, representing an ecological network connecting areas of existing, or potential presence of focal species. Based on mapping of current and historical occurrence of selected species of large predators and ungulates, areas of potential presence of such species were defined, including further analysis of connectivity of these areas. At the same time, all categories of anthropogenic and natural barriers were described. Migration corridors were designed over detailed topographic datasets, according to the results of habitat analyses of both groups of animals, and subsequently were tested in the field. The project resulted in a coherent network of existing and proposed migration corridors, with sections categorised according to permeability, as well as methodical protection and a management plan.
