Der Guardian schreibt über das Lupinenproblem (Wie eine Invasion lila Blumen Island zu einem Instagram-Paradies machte – und eine Krise der Artenvielfalt verursachte | Wildblumen)

Not a problem. It’s binding and creating soil for other plants to later grow in places where they otherwise couldn’t

>Now, there is broad agreement among most Icelandic scientists that the experiment has gone too far. The lupin occupies just 0.3% of Iceland, according to the most recent satellite assessment in 2017, but it is classified as an invasive species and continues to spread around the island at a rapid pace without human help, often squeezing out native plants and grasses. Scientists expect lupin coverage to have tripled by the next assessment in 2027, turbocharged by a warming climate. In the coming years, one study estimates that the species could grow to cover nearly a sixth of Iceland.

>“The history of the lupin in Iceland is one of good intentions and unexpected consequences,” says Pawel Wasowicz, director of botany at the Natural Science Institute. “Back in 1945, nobody knew about invasive species. The term didn’t exist. Nobody had an idea of climate change. You could get free packets of seeds at petrol stations to spread it. That’s how the invasion started. They thought it would be a medicine that solved their problems, but it has spread far more than expected,” he says. There are no serious efforts from Icelandic authorities to control its spread nationally.

>> “Revegetating land with lupins is like fixing a toothache with a rock. It’ll work, but you’ll most likely damage a whole lot of other things that weren’t damaged to begin with,”

> In areas where the lupin was first sown in southern Iceland, the moss layer beneath the flowers developed to the point that the flowers lost the ability to reproduce, giving way to native plants again. But scientists say **this process will only play out in some parts of Iceland, meaning the lupins will continue to spread and dominate**. For now, scientists say it is too late to eradicate the flowers. Instead, the best option may just be holding them back from some of the most biodiverse and precious areas.
