The name itself Ujście Warty - the Warta Mouth already indicates the location of this place. Tthe place, where the Warta ends and flows into the Odra river, a wide valley spreads out, which is part of Toruńsko-Eberswaldzka proglacial stream valley. Over 250 back, the part of the Warta behind Gorzów was divided into many meandering arms, which formed an inland delta, flowing into the Odra south of Kostrzyn. The Warta wetland (Warthe Bruch)was flooded by both rivers and o riparian forest grew in the area. Nowadays the lower Warta valley is drained and deforestated. Extensive farming system does not disturb existence of extremely attractive habitats vital for Poland and Europe.

The vicinity of Słońsk is dominated by open areas distinct from the rest of Lubuskie region, where about 50% of the land is covered with woodland. Periodically flooded meadows and pastures partly covered by willow trees and bushes cut overgrown old drainage canals. Dozens of kilometers of embankments make nature observation easy during walking and biking. The wide and flat valley is surrounded in the north and south by morainal hills and lakes creating a beautiful postglacial landscape. Among dominant coniferous forests in Lubuskie Lake District, you can also find pieces of interesting old deciduous woods - beech-, dry-ground-woods and alder carrs.

Warta floodplain, as one of the most important european wetlands of international importance, has been on the Ramsar List since 1984. About 270 bird species have been registered there, over 170 of them have bred in the area recently. In spring the Ujście Warty National Park is very important due to the breeding area of many rare and endangered bird species and the high density of some Polish bird populations. It concerns e.g. Shelduck, Gadwall, Oystercatcher, Shoveler, Greylag Goose, Red-necked and Black-necked Grebes, Black Tern and Little Gull.

The park is also a very important habitat for moulting, migrating and wintering birds. Flocks of 10-20 (sometimes over 100) Black Storks are very common in July/August. Outside the breeding season the park can hold Tundra Bean and White-fronted Geese (even up to 200 000), Cranes (around 20 000), ducks (78 000) and Whooper Swans (2 500).
White-tailed Eagles, which can be observed all year round, are most numerous in winter (50 is the maximum number observed).
