The mid forest Piskory Lake and the Nature Reserve (area of 203.02 ha) are located within the borders of the Wieprz Ancient River Valley Protected Landscape Area. This place is exceptionally abundant in fauna and flora species. The system of didactic paths with information boards presenting descriptions of birds and interesting facts from their lives, and special platforms facilitating animal watching, which have been created in the nature reserve, allow you to not only passively contemplate the local nature but also actively explore it.

The establishment of the reserve was associated with the implementation of the naturalization programme and biological enrichment of the lake and its vicinity in the years 1995–98. The introduced rare plant species fantastically acclimated to the area, thus enriching the species diversity and enhancing the natural assets of the lake and its vicinity. The capacity of the water reservoir is 1,500,000 m3.

The rather shallow Piskory Lake (up to 1.8 m deep) is in 98% covered with littoral zone plants, and therefore, this reservoir is considered as notably rich in natural assets. All waterfowl species can find very good conditions for nesting and preying here. The flora growing in the lake has characteristics of zone structure.

The shallowest east side of the lake, adjacent to alder forests out of which flow the stream tributaries feeding the lake (Rabik and Duży Pioter Streams), features willow thickets, accompanied by the Mannagrass Reed bed transforming into Carex Reedbeds that form characteristic clusters. The centre of the lake boasts interlacing stripes of the bulrush and common reeds, while in the deepest part near the outlet, the reservoir of the open water is partially covered by the communities of bulrushes.

The shoreline around the lake features mainly willow thickets, alder forests and oak-hornbeam forests. These areas boast a protected fern – the European Waterclover, which does not occur on any other sites in Poland, as well as the Floating Ferns and the Round-leaved Sundews that are under strict protection. Piskory is the habitat of waterfowl and wetland birds of highest value in the Lublin Region. Among about 120 species featured here are also very rare species, such as the Cranes, Black Storks, Great Crested Grebes, Red-necked Grebes, Black-necked Grebes, Grey Herons, Great White Herons, Greylag Geese, Common Kestrels, Eurasian Hobbies, Corn Crakes, Eurasian Woodcocks, Redshanks, and Garganeys. The abundant reeds provide shelter for the representative of the rail family: the Water Rails, Little Crakes or Spotted Crakes, and also to Eurasian Coots and Common Moorhen. Piskory is an ideal nesting site for terns – there are large colonies of the White-winged Terns and Black Terns, while Whiskered Terns can also be encountered here. The edge of the forest features the Nightjars, while the middle of the forest – the Eurasian Woodcocks. Among the accipitriformes, the most prominent is the largest bird of prey in Poland, the White-tailed Eagle. The Western Marsh-Harriers nest in the reeds. In the vicinity of the lake you can also see the Montagu’s Harriers, Common Buzzards, hawks, Eurasian Sparrowhanks and Common Kestrels. The swampy alder forests are an ideal habitat for the Eurasian Eagle-Owl, often spotted here by bird watchers.

In addition to birds, the area is abundant in the representatives of amphibians and reptiles: frogs, newts, lizards and snakes. Grass snakes occur in large numbers, while you can also encounter here the Common European Vipers. Among the game are roe-deer, deer, wild boars, muskrats, hares, pheasants, and grey partridges. The moose population is also large. The forests offer shelter to foxes, racoon dogs, badgers and martens. Around the entire lake you can encounter, or in fact see the activity of the beaver, the largest Polish rodent, which is manifest by the broken and gnawed trees.
