Over 4,000 of the 21,000 species assessed by the Swedish Species Information Centre are not considered to have Swedish populations that are viable in the long term. The trend is worst for marine life, and there are signs that biodiversity is also deteriorating in the mountains.
Unfortunately, the situation in forest and farmland habitats remains unchanged; these landscapes are where the majority of red listed species are found. However, long-term nature conservation work in freshwater habitats has begun to bear fruit –some amphibian species are among those whose status has improved.
New species on the Red List include fish such as lumpfish (Cyclopterus lumpus), whiting (Merlangius merlangus) and burbot (Lota lota) which have all declined considerably. The eel remains Critically Endangered and has been joined by the piked dogfish (Squalus acanthias). The Swedish freshwater crayfish is in rapid decline as a result of crayfish plague, and is also Critically Endangered.
The ash (Fraxinus excelsior)– the 'world tree' of Norse mythology – together with all three species of elm found in Sweden (wych elm (Ulmus glabra), field elm (Ulmus minor) and European white elm (Ulmus laevis)) have also been red-listed.
"They have been attacked and killed by fungal diseases. But it is essential that they are not cut down unnecessarily, because many insects and cryptogams depend on them," says Professor Ulf Gärdenfors.
But the new Red List also brings some good news. The wolf, lynx, wolverine and brown bear have all been classified as less threatened than on the last list. The brown bear has been removed from the list completely, since its numbers are now considered to represent a viable population. Under fish, the wels catfish (Siluris glanis) and asp (Aspius aspius) have also been given a less critical classification following several years' conservation work. The fire-bellied toad (Bombina bombina) has left the list entirely, as did the European tree frog (Hyla arborea) and the edible frog (Rana esculenta) when the last version of the list was published, again as a result of successful nature conservation.
The Red List is to be presented on 28 April at the Swedish Species Information Centre annual conference on flora and fauna conservation, held in Uppsala at the Ultuna campus of the Swedish University of Agricultural Sciences. Read more at http://www.artdata.slu.se/flofa/Background information:
The Swedish Species Information Centre is a national centre for knowledge on Sweden's wild plants, fungi and animals. Known information about the occurrence, ecology etc. of species is compiled and made available online from databases. The national Red List is produced on the basis of this knowledge. The list represents an assessment of the species that risk becoming extinct in Sweden. The Species Information Centre monitors the status of species and habitats given priority in the European Union. The Centre is also responsible for the Swedish Taxonomy Initiative, including the Encyclopedia of the Swedish Flora and Fauna. The Species Information Centre forms an administrative unit of SLU - the Swedish University of Agricultural Sciences, and is also an important interface between researchers, conservations and the general public.For more information please contact:

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
