The total of wild bee types in Europe experiencing extinction has over doubled in the last ten years, and the total of at-risk butterfly types has almost doubled.
This pressing issue for crucial pollinating species was disclosed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least 172 bee types out of 1,928 were facing extinction in the European continent.
The number of butterfly types at risk of extinction in the European continent has risen from thirty-seven to 65 since the previous assessment, carried out over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
“Beyond their aesthetic appeal and cultural importance, pollinating species like bees along with butterflies are essential supports for our physical condition, our food chains and our financial structures – sustaining the fruits, veggies and seeds that sustain us,” said the IUCN director general. “The newest European red list assessments reveal significant difficulties, with risks mounting for butterfly species and crucial non-managed bee species.”
The reasons of the quick recent decreases are the persistent harm or degradation of living environments caused by intensive agriculture and deserted farmland, draining of wetlands, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoid pesticides. The division of habitat friendly to pollinators substantially boosts the danger of local extinctions.
Global heating is also demonstrated to be a significant danger: 52% of all threatened butterfly species in the European continent are endangered by the climate change crisis – roughly twice as many as a decade ago.
Up to ninety percent of blooming plants in European nations depend on insect pollination, according to the wild bee assessment’s lead coordinator. “Sadly, native bee colonies are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If wild bees vanish, many native plants might be at risk too – of which meadows rich in flowers and beautiful orchid species are just a handful of illustrations.”
Fifteen types of bumblebee species, which have an essential part in pollinating peas, beans, peanuts and clover, and 14 types of cellophane bee species, known for fertilizing trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type found only in the mainland and the only species of this genus in Europe, is now evaluated as critically at risk – the scientific classification nearest to disappearance in the wild.
Butterfly types that are only found on mountain peaks are especially at risk to global heating as they need to move uphill as their habitats become more heated but ultimately have no room left. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among over forty percent of types unique to Europe (only found in Europe) at risk of extinction.
In the Mediterranean, species such as the highly at-risk Karpathos grayling are endangered by intense drought and wildfires.
In the meantime, in the Arctic region, climate change is leading to the timberline to advance northwards by dozens of meters each year, with scrub taking over wetlands and tundra. Warmer conditions also mean reindeer can not anymore cross the ice to browse northern grasslands and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this zone, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The biggest living space for all these pollinating species is bloom-filled grassy areas and that is disappearing very fast across the European continent because of all these factors,” said a lead coordinator for the butterfly assessment. “The good news is that so many citizens are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to turn around the decline in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are property owners who are engaged. We hope they can get the incentives that will support them on their way.”
According to the coordinator, there is “low-hanging fruit” in terms of action for pollinating species which won’t reduce food production – and may enhance it – such as growers establishing margins rich in flowers around their cultivated areas.
EU commissioner for environment, described the protection status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Prompt and unified steps is required to address this risk. Together with member states, the Commission of the European Union has established an EU-wide monitoring system for pollinating species based on the EU nature restoration regulation, which will help to track our progress. Now, we need to prioritize execution and partnership with participating nations to protect our pollinating insects,” she said.
The publication of the evaluations of bees along with butterflies follows the pioneering Europe-wide evaluation of hoverflies, a further vital group of pollinators. Published in twenty-twenty-two, it disclosed that thirty-seven percent of all hoverfly species in European nations were facing extinction.
