Vorma


Year of compilation: 2000

Site description
Vorma is the initial stretch of the largest river in Norway, the Glomma, flowing out of Mjøsa, the largest lake in Norway. The most important places for birds at this site are found between the outlet from Mjøsa and Eidsvoll, and along the Andelva river which flows from Lake Aurdal into the Vorma river. The area around the rivers is mostly cultivated. Water is used for electricity generation.



Key biodiversity
The best area for Cygnus cygnus is up the Vorma river from Eidsvoll Station to Minnesund at the outlet of Lake Mjøsa, an area that does not freeze in winter.



Pressure/threats to key biodiversity
As part of the development of a new main airport in Norway at Gardemoen, there is a railroad planned along the Vorma river upstream from Eidsvoll station. This is the most important area for swans Cygnus, and could be critically impacted. Wintering swans and other waterbirds have been counted at Vorma and Glomma since 1988. The Norwegian railroad bureau (NSB) has also initiated studies on wintering waterbirds, related to new railroad projects in the area.
