Belt in Balance

Naturpark Lillebælt’s Project for the Aquatic Environment

Belt in Balance

Through “Belt in Balance”, Naturpark Lillebælt will communicate, research, and improve the sea and coastal environment near the Little Belt for the enjoyment of citizens, visitors, and many volunteers, ad with support from two foundations.

Overall budget: 35.3 million DKK

Backing from foundations: 17.1 million DKK

Timeframe: April 2020 – April 2025

What is our Purpose With the Project?

  • We want provide and tell people about new, exciting nature experiences along Denmark’s sea and coast, so people get a deeper understanding of the marine and coastal areas, as well as a fascination, enjoyment, and interest in once again visiting the sea and coast.
  • To create specific improvements to the aquatic environment – the core of Naturpark Lillebælt. We create new stone reefs, biohuts (fish kindergartens), fishing for crabs, voluntary preservations, and minor noise in the sea. These initiatives shall provide better living conditions for cod, sea trout, and porpoises, and fewer crabs. Budget: 6.5 million DKK. Of these, 3.42 million DKK go towards 8,555 m3 rocks and 0.25 million DKK go towards biohuts.
  • Provide knowledge about the Little Belt through research into the improvements for porpoises, cod, fry, and sea trout. Budget: 5.6 million DKK. Of these 3.38 DKK go towards DTU Aqua and AU.
  • Communicate knowledge and research to citizens, visitors, and associations. We will improve the facilities and the mediation out by Naturpark Lillebælt’s coast, so especially schools and young people receive better opportunities to experience the sea, learn, and understand what happens beneath the surface. Budget 23.2 million DKK. Of these 9.6 million DKK go towards facilities and mediation.

What can you do?

You are very welcome to participate in this project. For example by:

  • Loaning boats to researchers, when they are researching cod/porpoise reefs, smolt reefs, and reservations.
  • Catching cod and sea trout at specific times, so they may be marked and monitored.
  • Adopt a fish kindergarten. Help take care of and track the development in the fish kindergartens, so we can see if more fish gather around it.
  • Input to new installations along the coasts, which focus on the mediation of sea and coast.
  • Your stories about the Little Belt Sea and coast, as a communicator or guide for schools or visitors.
