Site name and code: Teklusia PLH160017
Special Area of Conservation
Site of Community importance since 2011
Area: 316.48 ha
Administrative location: Opole voivodeship: Kluczbork county – municipality of Wołczyn.
The area is located in a valley depression of the Wołczyńska Struga tributary, slightly dissection adjacent glacial upland. The bottom of the valley is flat, lined with alluvial soil, silt and peat.
Teklusia is one of the few sides with preserved, diverse natural habitats in the agricultural landscape of the Silesian Lowland. The site consists mainly of fragments of the Jakubowska Woda stream valley which is a tributary of Wołczyńska Struga, which flows into the Stobrawa (the Odra river drainage basin). A characteristic feature of this valley is peat deposit lined on the ground. Its central part, once used as meadows and pastures in the second half of the twentieth century, has once again become a bog as a result of the cessation of the meadow management and the lack of renewal of the drainage and irrigation ditches and drains system. In this part, riparian forests and alder phytocoenosis have developed. Its southern part has been colonized by beavers whose building a dam on the main watercourse bed contributed to additional flooding of the area. However, the substantial part of the refugium continues to be used as hay meadows, characterized by a mosaic structure of plant communities and the great rich flora. Occurring plant communities represent all wet sedge rushes, bog meadows, intermittently wet meadows, as well as hay meadows. Important elements of the site landscape in the area of the settlement Teklusia are small enclaves of meadows and pastures surrounded by fragments of forest and woodlots. The existing mosaic of plant communities creates favorable habitat conditions for different groups of animals, of which birds have been initially recognized.

A description of the subjects of protection within the site
Beavers play a major role in shaping the humidity conditions of the site. Within the area there is probably only one permanent population of the family, which is too little for beavers to remain the subject of conservation within the site. On the outskirts of alluvial forest there are preserved fragments of bog meadows and intermittently wet meadows with rare species of plants, such as the broad-leaved marsh orchid Dactylorchiza Majalis and bogbean Menyanthes trifoliata, and rare species of purple marshlocks Comarum palustre, Senecio rivularis and fibrous tussock sedge Carex appropinqua, which forms its own community rarely occurring in south-western Poland. Meadows with highly diverse composition of phytocoenoses are also very valuable within the site, they are reflecting the diversity of the local-habitat conditions and, moreover, the degree of humidity, trophy substrate and the intensity of its use. In particular the meadow situated at the northern end of the area in the direction of Skałąg and west towards Komorzna, which is characterized by rich floristic composition should be mentioned. The most valuable fragments of grasslands are the ones with protected fern – adder’s-tongue Ophioglossum vulgatum or locally endangered species such as sneezewort Achillea ptarmica and shining meadow rue Thalictrum lucidum. The refugium fills a gap in the protection of grassland habitats on the border of Silesia and Wielkopolska Region.
….. Teklusia is the northernmost of Natura 2000 sites, situated within the Opole voivodeship.
….. beaver is the only species of European animals that just as a man is able to shape the environment of its life. European beavers were reintroduced in the Opole region, so reinstated in the environment, at the turn of the twentieth and twenty-first century.
….. Transition mires owe their name to indirect water conditions that affect their humidity. These are the habitats with typical peat plants (e.g. peat moss) and also bog plants (bogbean, purple marshlocks) occurring.
