Facts:
Biodiversity refers to the variety within a species, between species, and across ecosystems. High biodiversity enhances the resilience of ecosystems and species—their ability to cope with changes.
We identify, measure, and analyze threats to biodiversity, proposing and evaluating the impact of measures to mitigate biodiversity loss. Our work focuses on endangered species like the noble crayfish and the eel, as well as invasive species such as round goby, American lobster, signal crayfish, and pink salmon.
The state of global biodiversity is critical, and significant changes are needed to reverse the negative trend. The loss of biodiversity is often caused by human activities such as habitat destruction, overexploitation, and the spread of invasive species.
An invasive species is one that, with human assistance—whether intentional or accidental—has been moved from one area to another, crossing a natural barrier (e.g., freshwater species from North America introduced into Swedish water systems). Some invasive species are harmful, meaning they negatively affect native plants and animals or cause economic damage.
Perhaps the most impactful event has been the introduction of the signal crayfish, which has been a carrier of crayfish plague, putting the native freshwater crayfish population at great risk.
You can report invasive species directly on Artportalen or in Rappen. For American lobster sightings, you can report directly to us.
