Ornithological information 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).
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.

Habitats
| IUCN habitat | Habitat detail | Extent (% of site) |
|---|---|---|
| Coastline | Mud flats & sand flats; Tidal rivers & enclosed tidal waters | 18% |
| Sea | Sea inlets and coastal features | 80% |
Land use
| Land-use | Extent (% of site) |
|---|---|
| fisheries/aquaculture | 20% |
| urban/industrial/transport | 5% |
Management considerations The entanglement and drowning of seabirds in fishing nets is a major problem, especially in spring. Land-claim for industrial development and roads has destroyed mudflats in the inner parts of the fjord. Further road-building is planned, but no final decisions in this respect have yet been made.
