The forest reserve was established by the ordinance of the Minister of Environmental Protection, Natural Resources and Forestry of December 31, 1993, on an area of 160.56 ha. It was created thanks to the efforts of prof. Witold Rosa, head of the Forest Management Department at SGGW in the years 1977-1985. It is located on the south-eastern edge of the Nieporęt commune, in the fork of the Marki-Nieporęt and Marki-Legionowo roads, on the Czarna river. The name refers to the historical forest in the vicinity of Słupno, which was heavily thinned by logging and peat exploitation. The reserve is dominated by riparian forest, alder swamps, oak-hornbeam forests, and mixed coniferous forests. 80% of the tree stand is alder and birch. Rez. “Puszcza Słupecka” is one of the most valuable forest areas in Mazovia. Many rare protected plant species occur here, including the mezereon (Daphne mezereum) – a highly poisonous plant whose fruits can cause human death if ingested. In the reserve, golden orioles, black storks, and cranes nest, and moose, roe deer, wild boars, raccoon dogs, and foxes occur, as well as the adder among reptiles.

Rezerwat Puszcza Słupecka. The reserve was established to preserve, for scientific and educational purposes, diverse forest communities: alluvial forests, oak-hornbeam forests, and pine forests with rich occurrences of protected, rare, and endangered plants. The reserve itself is not open to visitors, but the old railway line to the peat mine runs along its edges (on the embankment).

Very nice singles in the area, unfortunately it is not that easy to get there... especially from the south.

The lake has dried up but there are three shelters. A good place for a short stop.
