Site description
The site comprises the stretch of the Nida river valley between the villages of Mostowice and Skowronno Dolne, as well as a wedge of a few square kilometres' area between Umianowice and Skowronno. The valley widens gradually up to 6 km width, to the gorge near the village of Sobowice. The whole of the site is covered by a system of small watercourses, and there are four low hills. There are many oxbow lakes, mires and seasonally flooded areas with aquatic vegetation (e.g. Potamogeton) and reed Phragmites. Amongst the meadows there are areas of wet alder Alnus forest and clumps of willow Salix, while the riversides are lined with trees/scrub of Salix and poplar Populus.

Key biodiversity
A total of 125 species have been recorded breeding, including 47 waterbirds.
