An ecological network in the landscape consists of all existing and proposed landscape segments of ecological significance that can contribute to the conservation of landscape biodiversity. The concept of creation of territorial systems of ecological stability applied in the Czech Republic corresponds to the latest landscape ecological knowledge and landscape planning procedures used abroad. Biocorridors interconnect biocentres thus enable migration, interactions and permeability of landscape for organisms. Unlike biocentres, they don't need to provide for a permanent existence of all species of the represented communities. Thanks to the interconnection of biocentres by means of biocorridors there is an ecological network forming in the landscape. Development of the local biocorridor Vracov and the regional biocorridor Věstonice in south Moravia is presented.
