International day for biological diversity

Biodiversity is important for healthy ecosystems and for things that people depend on, such as crop pollination, clean water, a stable climate, and pleasant natural environments. When biodiversity decreases, nature becomes more sensitive and vulnerable. Climate change makes the situation worse because animals and plants find it harder to survive when their habitats change. At the same time, balanced ecosystems can help slow climate change by storing carbon dioxide and reducing the effects of extreme weather. Protecting biodiversity is therefore also important for the climate.

Invasive species – a threat to biodiversity

Invasive alien species are a threat to biodiversity. These are species that spread quickly in places where they do not naturally belong. They can take over areas, outcompete native Swedish species, and change ecosystems. Since they often lack natural enemies in their new environment, they can have a major impact on nature in a short time.

New national list to be aware of

The Swedish government has introduced Sweden’s first national list of invasive species. It came into effect on May 15, 2026, and includes 34 species considered especially harmful to nature in Sweden, both on land and in water. The new list complements the EU list and makes it possible to act early against species that are not yet a major problem across Europe but risk causing damage here.

Examples of species found here in Boden and included on the new national list are Canadian goldenrod, Japanese rose, and lupine. The underwater plant Canadian waterweed is also included on the list.

What do the rules on invasive species mean?

• More species are now regulated nationally in addition to the invasive species listed by the EU.
• It is forbidden to spread, sell, intentionally grow, or release the identified invasive species into nature. This also applies during transport.
• Put all plant material in sealed bags and dispose of it as combustible waste or at a recycling center — never in compost or in nature.
• Landowners and operators are responsible for preventing the spread of invasive species from their properties.
• Measures must be taken when invasive species are found in order to prevent further spread.

What can you do?

• Plant native species whenever possible.
• Do not dump garden waste in nature.
• Report sightings of invasive species to the Swedish Species Information Centre (Artdatabanken).

Together, we can make a difference!
