Ostoja Sławniowicko – Burgrabicka – EN

Site name and code:          Ostoja Sławniowicko – Burgrabicka PLH160004

Site of Community Importance since 2008

Area: 771.6 ha

Administrative location: Nysa country – municipality of Głuchołazy.

Bombina variegata

The site is a part of the Eastern Sudetes, including villages of Sławniowice and Burgrabice. The refugium is a very important element in the ecosystem of the region – here are the key species of bats and amphibians, including particularly valuable breeding and wintering colonies of lesser horseshoe bat. This species occurs in Poland mainly in the Carpathian Mountains, in the Sudetes it occurs around Sławniowice, Burgrabice and Głuchołazy. This species of bat is at risk of extinction, however within the refugium it occurs in large numbers; there are its wintering and two breeding places. Another species occurring in the area is greater mouse-eared bat (summer colonies). The bats especially like the premises of the mine in Sławniowice and the church in the neighboring Burgrabice. The site is also important for the yellow-bellied toad. It is one of two places of its occurrence in the Sudetes (here runs the boundary of the range of the occurrence of the species in Poland).

A description of the subjects of protection within the site

Bombina variegata

The information collected during work on the project revealed that the site of the lesser horseshoe bat as key species is now in a good state of preservation. The population has been maintained in the area for many years, both in terms of summer and wintering colonies. Confirmed numbers put the breeding colony in second place in Poland and definitely the first in the Sudetes. We can therefore be optimistic about the future of this species, but in order to maintain favorable living conditions for horseshoe bats and greater mouse-eared bats, which form colonies together, the risks that may prevent the existence of these species should be seriously taken into account. The major threat to bats inhabiting the mine is a change of use of the building. The danger may be in improperly carried out repairs, sealing the inlets and their illumination. In the case of winter shelters risks would be mainly related to changes in microclimate of the wintering grounds, caused primarily by penetration or filling (sealing) inlets by humans. In order for bats to have a safe access to breeding and feeding sites, attention should be paid to the preservation of trees and shrubs formations around their wintering and resting places, and in case of summer shelters (attic of the church and the industrial building) to maintaining existing inlets.

More facts:

…. the mezereum has been found within the refugium, i.e. a small shrub flowering in early spring. Fruits, leaves and bark of this species are toxic, so even skin contact with the plant can cause swelling and blistering.

… also another valuable species has been identified within the site – the red algae Hildenbrandia rivularis, listed in the Red List of threatened algae in Poland as a vulnerable plant. Sanguineous thallus of the red algae is a flat crust tightly adhering to the stones submerged in water, which looks like thin deposit. This species grows in relatively clean flowing waters.
