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.
