Site description (2000 baseline)
The site consists of the Otra river and surrounding areas. The river is the largest in the southernmost part of Norway, and has been regulated for hydroelectric purposes to a great extent, although no dams exist within the site itself. Forests cover most of the surrounding area, mainly consisting of pine Pinus.

Key biodiversity
After several decades of very low breeding numbers in Norway, due to the severe influence of acid rain on freshwater ecosystems, Pandion haliaetus are now increasing in this area, probably as a result of full national protection of the species in 1962, and re-colonization following the re-introduction of trout Salmo trutta and the liming of rivers and streams.
