Laajalahti bay, Vanhankaupunginlahti bay and Viikki

Year of compilation: 2000

Site description
The site includes two shallow, sea bays, dominated by reed Phragmites, and a largish area of adjacent farmland, situated close to Helsinki. The farmland of Viikki is separated from Vanhankaupunginlahti by a narrow zone of young, wet, deciduous forest and by some older mixed forest.

Key biodiversity
An important breeding and staging area for wetland birds. The site also supports one of the largest national populations of a breeding bird new to Finland, Panurus biarmicus (65 pairs).

Pressure/threats to key biodiversity
The entire area suffers from considerable human impact. All parts of Viikki are cultivated, and recreational activities, especially hiking and birdwatching, are common. Housing development and road construction plans seriously threaten parts of the area. Water quality has improved in recent years as a result of new and effective sewage treatment. Laajalahti and Vanhankaupunginlahti have several bird-watching towers and wooden trails. Part of the area is a candidate SAC.
