Uggleviken

Together with Lillsjön, Laduviken and Storängsbotten, Uggleviken used to be part of a bay forking across Norra Djurgården.

The Royal Institute of Technology occupies approximately 20 per cent of the catchment area and on the west side are a number of allotment-gardens.

Pipes from settled areas opening out on the southern side are believed to be the major environmental burden, together with run-off water from the road north of the wetland.

Specimens in isolated ponds in the area contain species of Oligochaeta, and Gastropoda, such as Valvata cristata and Anisus leucostoma.

Many species of birds are found in the marsh, including thrush nightingale, redwing, dunnock, and Eurasian wren.
