Overview

In the west of Poland close to the German border is a large area of marshes where the Warta, Odra and Postomia Rivers meet. This area is a Landscape Park, a Ramsar Site and the Slonsk Reserve, an extremely important passage stopover and wintering site for tens of thousands of waterfowl and other birds.

In addition the area is the most important wetland in western Poland for breeding birds and around 160 species have been known to nest out of a total of more than 240 species recorded. The reserve covers more than 4000ha of rivers, oxbows, a reservoir, shallow lakes and drainage channels set in a landscape of regularly flooded meadows and pastures.

Birds

Notable Species

Lesser Spotted Eagle can be seen in summer as well as both kites, Marsh Harrier and Montagu's Harrier breed and White-tailed Eagle, a former regular breeder, is now mainly a winter visitor.

Summering waterfowl include Greylag Goose, Common Shelduck, Gadwall and Northern Shoveler. Breeding passerines include Thrush Nightingale and Fieldfare, Penduline Tit and Hawfinch.

Warblers are numerous and varied with Grasshopper Warbler, Savi's Warbler and River Warbler, Marsh Warbler, Reed Warbler and Great Reed Warbler, Sedge Warbler and sometimes Aquatic Warbler in the wetlands and Barred Warbler, Icterine Warbler and others in scrub and woodland.

A wide variety of waders and waterfowl visit these marshes on passage and the area also attracts Common Crane in good numbers. Slonsk is an important wintering ground for geese, particularly Greater White-fronted Goose and Bean Goose, and also for large numbers of Whooper Swan. White-tailed Eagle is present in winter.

Site Information

Areas of Interest

There is a dam from Slonsk north towards the River Warta which gives good views but ask permission at the pumping station before walking it.

Access and Facilities

Some of this area is rather inaccessible and much of the reserve requires a permit to visit. However, there is a road from the north-west of Slonsk village that passes through part of the reserve and much can be seen from the roads to the east of Kostrzyn.

There is a border crossing from Germany at Kostrzyn which is only a little over 100km east of Berlin.

The nearby town of Gorzow Wielkopolski has hotel accommodation.
