Endangered Species in Sweden

Sweden's wildlife has been shaped by centuries of human activity — hunting, forestry, agriculture, urbanisation, and now climate change. While some species have recovered dramatically (brown bear, white-tailed eagle, beaver), others remain critically threatened. The Swedish Species Information Centre (ArtDatabanken (Species Data Bank)) at the Swedish University of Agricultural Sciences (SLU) maintains the Swedish Red List — the definitive assessment of which species are at risk and why.

The Swedish Red List

The most recent Red List (2020) assessed over 21,600 species. Of these, approximately 4,750 were classified as threatened or near-threatened — roughly 22 per cent of assessed species. The breakdown:

The Arctic fox is Sweden's single most endangered mammal. From a Scandinavian population of fewer than 50 adults in the early 2000s, intensive conservation has raised numbers to roughly 450 across Sweden, Norway, and Finland — but the species remains critically endangered and dependent on human support.

Why endangered:

Competition from the red fox, which has expanded into higher elevations as climate warms
Disruption of lemming cycles (the fox's primary food source)
Small, fragmented population vulnerable to inbreeding

Conservation actions:

Supplementary feeding stations in the mountains
Red fox culling in Arctic fox habitat
Captive breeding programme at Nordens Ark zoo (Bohuslän)
Cross-border coordination with Norway and Finland
Genetic monitoring to manage inbreeding

Lesser Horseshoe Bat (Liten hästskonäsa (Lesser Horseshoe Bat))

Once found across southern Sweden, this tiny bat now survives in only a handful of sites, primarily in Skåne. Loss of insect-rich habitat, disturbance of hibernation roosts, and pesticide use have pushed it to the brink.

Endangered Birds

Lesser White-fronted Goose (Fjällgås (Lesser White-fronted Goose))

Ortolan bunting (Ortolansparv (Ortolan Bunting)) — Critically Endangered in Sweden; agricultural intensification destroyed its habitat
White-backed woodpecker (Vitryggig hackspett (White-backed Woodpecker)) — Endangered; requires deciduous forest with abundant dead wood — now extremely rare in managed Swedish forests

Endangered Marine Species

Baltic Harbour Porpoise (Tumlare (Harbour Porpoise))

The Baltic Sea harbour porpoise population is critically small — estimated at fewer than 500 individuals in the Baltic Proper. Bycatch in fishing nets, underwater noise pollution, and environmental contaminants are the primary threats. The Belt Sea population (western Baltic) is healthier at ~40,000.

European Eel (Ål (European Eel))

Sweden's native crayfish (Astacus astacus) has been devastated by crayfish plague — a fungal disease carried by the invasive North American signal crayfish (Pacifastacus leniusculus), which was introduced to Swedish waters in the 1960s. The noble crayfish survives in isolated, plague-free waterways but its long-term future is uncertain. Most crayfish consumed at Swedish kräftskivor (crayfish parties) are now signal crayfish or imported.

Threatened Habitats

The species most at risk in Sweden are often tied to specific habitats that have been lost or degraded:

Old-Growth Forest

Less than 5% of Sweden's productive forest qualifies as old-growth. The species that depend on it — dead-wood beetles, old-growth lichens, cavity-nesting birds — are among the most threatened groups on the Red List. Over 2,000 Red-Listed species are forest-dependent.

Traditional Meadows and Pastures

Over 90% of Sweden's flower-rich ängsmark (meadowland) has disappeared since the mid-20th century. With it, hundreds of insect, plant, and bird species have declined. The remaining hay meadows and grazed pastures are among Sweden's most biodiverse habitats — and among the most labour-intensive to maintain.

Wetlands

Drainage for agriculture and forestry has destroyed or degraded a significant proportion of Sweden's mires and wetlands, particularly in the south and centre. Wetland restoration is increasingly prioritised, both for biodiversity and for carbon storage.

Baltic Sea Floor

Large areas of the Baltic seabed are now oxygen-depleted "dead zones," caused by eutrophication. These hypoxic conditions eliminate bottom-dwelling fauna and disrupt the food web. The dead zone area fluctuates but has exceeded 60,000 km² in bad years.

Conservation Programmes and Success Stories

Sweden invests significantly in species conservation, with notable successes:

Brown bear: From ~130 (1930) to ~2,800 today
White-tailed eagle: From ~50 pairs (1970s) to ~900 pairs today
Beaver: From extinct in Sweden to ~130,000 today (reintroduced 1920s)
Peregrine falcon: From near-extinction (DDT era) to ~400 breeding pairs
Wolf: From extinct (1960s) to ~400–500 individuals, though still controversial

Rewilding Initiatives

Rewilding efforts in Sweden include:

Restoration of natural water flows in rivers (removing small dams, reconnecting floodplains)
Forest set-asides and dead wood retention in commercial forestry
Reintroduction of grazing animals to maintain open landscapes
Wetland restoration (returning drained mires to natural conditions)
Corridors and connectivity planning, particularly for large carnivores

The Swedish Environmental Protection Agency (Naturvårdsverket (Environmental Protection Agency)) coordinates national conservation strategy, while county administrative boards (länsstyrelser (county boards)) implement regional measures.
