Biological diversity

Diversity is extremely important, no matter it is at land or at sea. Our goal is to preserve the biological diversity and in order to do so we apply our blue-green strategy.

The Port of Oslo makes our city green where we can, and give much-needed space to vulnerable species.

The islands near the Port of Oslo have vulnerable species and protected areas. Our port activities can have a devastating effect on these islands. However, we are very aware of the damage that could occur and the organisation does everything it can to to reduce the risk.

On land, the greatest challenge is the invasive plants that threaten to out-compete the native flora. The Port of Oslo fights these black-listed species every season, and prevents them from spreading to the protected areas, such as Hovedøya. That is how the Port of Oslo contributes to monitoring and protecting threatened species in our harbour.

In the ocean, the Port of Oslo in cooperation with the City Council works to meet the demands made by the Water Framework Directive to achieve good ecological status. Artificial reefs and blue-mussel ropes have been deployed in Bjørvika outside the Opera House, and at Tjuvholmen.

The blue-green strategy is the Port of Oslo's plans to keep the city's emissions out of the fjord. That means that the port needs to completely stop its own pollution as well as keeping an eye on the fjord in such a manner that its future stays blue-green.

The reefs have led to a healthier ecosystem, and the mussel ropes keeps the water clean.

Blue-green strategy in Port of Oslo:

No-species in Oslo port – blacklisted species

Yes-species in Oslo port - vulnerable species
