Location
Cieszynskie Zrodla Tufowe site is situated in the western part of the Silesian Foreland, customary called the Cieszyn Foreland (Cieszyn and Biała Watersheds according to J. Kondracki). The site encompases the area of 2,7 km2 within Jasienica, Debowiec, Goleszow, Skoczow communes. The site includes four isolated, active spring areas:
Geology and land formation
The unique value of the Cieszyn Foreland is the geological formation of the area. Gentle hills, which are cut by numerous deep v-shaped valleys, are built of rocks belonging to the strongly undulated Cieszyn nappe (the Cieszyn beds). Marls and schists with limestone insert (so-called the lower and upper Cieszyn schists) and the Cieszyn limestones which build the majority of the Cieszyn Foreland culminations because of their resistance, dominate in the bedrock of the site. They represent a particular type of calcareous flysh, exceptional in the Polish Flysh Carpathians.
Interesting that among sedimentary rocks occur magmatic rocks veins, which were folded together with sediments of the Cieszyn nappe. Outcrops of these rocks can be observed in closed quarries in the vicinity of Goleszów and Grodziec.
Ecosystem
Natural peculiarities of the site are springs flowing out in the contact zone between the Cieszyn limestones and marls or schists. The springs are characterized by small (0.2-2 l/s) but constant outflow as well as small variability of physical and chemical properties during the year (water temperature between 8.5-9.1 °C). The spring waters are slightly alkalic and intermediary between normal fresh water (mineralization up to 0.5 g/l) and mineral water (more than 1 g/l).
Some of the springs are accompanied by active deposition of calc-sinter (calcareous tufa and travertines). They are deposed in a physical way (on thresholds) and in a biological way (activity of mosses and algae).
Within the area of the site the following habitat types from Annex I of Habitat Directive have been identified:
Flora and fauna
The area of Cieszynskie Zrodla Tufowe is marked by plant biodiversity. Many interesting plant species can be found here including: horsetail, autumn crocus, Common Spotted Orchid, oxlip, European Common Twayblade.
The world of animals is represented by amphibians: Fire Salamander, European Fire-bellied Toad and Great Crested Newt.
Nature protection
The area is mostly unprotected. It includes two nature reserves: Morzyk (11.47 ha; 1996) and Skarpa Wislicka (24.17 ha; 1996). Two other nature reserves: Turowka (on Gora Jasieniowa hill) and Kamieniec are planned.
