Description of the Area Surrounding the Biotope: River in the Western Bieszczady, the largest tributary of the San River after Osława. It is 48.1 km long and is the third in the Bieszczady Mountains in this respect. Its sources are located on the southern slopes of Rosocha in the Hyrlata massif, at an altitude of approx. 1000 m above sea level. It flows into Lake Solińskie in the village of Bukowiec. At the beginning, it flows around the massif of Hyrlata from the west, flowing through the town of Solinka. Then it flows eastwards through Żubracze and Majdan, separating Wysoki Dział from the border zone. Further, behind Cisna, which is the largest town lying on the river, its valley is the border between the Łopiennik and Durna ranges and the Jasło ridge belonging to the border range. In the area of Dołżyca turns to the north and flows between the massifs of Łopiennik and Falowa. Behind the village of Buk, the largest tributary – Wetlina – flows on the right. Then, through Polanki, Terka and Bukowiec, it reaches Lake Solińskie. Its waters form the western part of the reservoir, which in the vicinity of Polańczyk joins the San flowing in the eastern branch. The Bieszczady Mountains are built of sedimentary rocks, clay shale and sandstones, which are generally referred to as the Carpathian flysch. These sediments were formed in the Cretaceous to the Older Tertiary (Paleogene) period, and then uplifted and folded in the Early Tertiary (Neogene) period. in the river valleys, we can find especially alders, ash, fir and many species of willows.
