The count of native bee types in Europe experiencing extinction has over doubled over the past decade, whereas the number of at-risk butterfly species has nearly doubled.
This dire scenario for crucial pollinating species was revealed by scientific studies for the red list of threatened species, which found that at least over 170 bee varieties out of nearly two thousand were threatened with extinction in the European continent.
The count of butterflies threatened with extinction in the European continent has risen from 37 to over sixty since the previous assessment, conducted a decade and a half ago. One species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
In addition to their beauty and cultural value, pollinating species like bees and butterflies are crucial elements for our well-being, our food supplies and our economies – sustaining the produce, vegetables and seeds that sustain us,” commented the IUCN director general. “The most recent assessments of the European red list reveal serious challenges, with dangers growing for butterfly species and vital wild bee species.”
The causes of the quick recent decreases are the persistent harm or degradation of living environments caused by agricultural intensification and land abandonment, wetland drainage, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoid chemicals. The division of pollinator-friendly habitat significantly raises the risk of disappearances in specific areas.
Climate change is also revealed to be a major threat: Fifty-two percent of all at-risk butterflies in the European continent are imperilled by the climate crisis – approximately double the number as a decade ago.
As many as 90% of blooming plants in European nations depend on animal pollination, as stated by the wild bee assessment’s lead coordinator. “Sadly, native bee populations are in severe drop and are not easily replaceable by domesticated hives,” he said. “If native bees die out, many native plants might be in danger as well – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
Fifteen types of bumblebee species, which play a crucial role in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for fertilizing trees such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the sole species of this genus in the European continent, is now classified as critically at risk – the research category closest to extinction in the wild.
Butterfly species that are exclusively located on mountain tops are particularly vulnerable to global warming as they have to climb upward as their habitats become hotter but in the end have no room left. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of species endemic to Europe (only found in Europe) at risk of extinction.
In the Mediterranean, types such as the highly at-risk Karpathos grayling are imperilled by extreme wildfires and drought.
At the same time, in the Arctic region, global heating is causing the forest boundary to advance northwards by tens of metres each year, with underbrush taking over marsh and tundra. Warmer conditions also mean reindeer can no longer cross the frozen water to feed on northern grasslands and maintain them clear. Eight types of butterflies are threatened with extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The largest living space for all these pollinators is grassland rich in flowers and that is declining quickly across European nations because of all these reasons,” said a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many people are aware now and there’s a lot more understanding. Under the European Union nature restoration law, all member states have to halt the decline in pollinators by 2030, and they are going to have to begin taking action. There are landowners who are interested. We hope they can get the encouragements that will assist them on their way.”
According to Warren, there is “readily achievable actions” in terms of steps for pollinating species which will not decrease agricultural output – and could improve it – such as farmers establishing bloom-filled edges around their farmland.
Jessika Roswall, characterized the preservation condition of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Prompt and unified steps is necessary to tackle this risk. Along with participating nations, the EU Commission has established an Europe-wide monitoring system for pollinating species based on the European Union nature restoration legislation, which will aid in following our progress. Now, we need to concentrate on implementation and partnership with participating nations to safeguard our pollinating species,” she said.
The release of the assessments on bees and butterflies is subsequent to the first Europe-wide study on hoverflies, a further essential pollinating insect category. Issued in twenty-twenty-two, it showed that 37% of all hoverfly varieties in European nations were at risk of extinction.
