Site description
A 10-km long fjord in the south-eastern part of the Trondheimsfjord, 20-25 km east of Trondheim. At the outlet of the Stjørdalselva river there are meadows, intertidal flats of sand and mud, and shallow subtidal habitat. Further out, on the northern side of the site, there are fewer mudflats. The sea here is still quite shallow: as far as 1-2 km offshore it is not more than 10-20 m deep.

Key biodiversity
This is a notable staging area for congregatory seabirds and waterbirds, especially in spring˜for example, in April there are 20,000-30,000 seabirds present. Birds are partly attracted by herring roe, which may be washed ashore in layers up to 0.5 m thick during storms and rough seas (the area is important for spawning herring Clupea harengus in spring).
