The number of wild bee varieties in the European continent experiencing disappearance has more than doubled over the past decade, and the total of endangered butterfly types has nearly doubled.
This critical situation for essential pollinators was disclosed by scientific assessments for the red list of threatened species, which found that at least over 170 bee species out of 1,928 were at risk of extinction in European nations.
The total of butterfly types facing extinction in the European continent has increased from thirty-seven to 65 since the last study, performed a decade and a half ago. One type, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
In addition to their aesthetic appeal and cultural importance, pollinating species like bees along with butterflies are lifelines for our well-being, our food systems and our economic systems – sustaining the fruits, veggies and seeds that feed us,” commented the IUCN director general. “The newest European red list evaluations reveal major obstacles, with threats mounting for butterfly types and essential native bee species.”
The causes of the quick recent decreases are the persistent destruction or damage of natural habitats caused by agricultural intensification and land abandonment, wetland drainage, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of environments suitable for pollinators greatly increases the danger of disappearances in specific areas.
Global warming is also revealed to be a primary risk: Fifty-two percent of all endangered butterfly species in European nations are threatened by the climate crisis – roughly twofold the amount as a previous decade.
Nearly 90% of plants that flower in Europe rely on pollination by animals, as stated by the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee groups are in severe drop and cannot be easily replaced by managed bee colonies,” he said. “If wild bees vanish, many native plants might be threatened too – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen types of bumblebee types, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee types, recognized for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species unique to the continent and the single type of this genus group in Europe, is now classified as severely threatened – the scientific classification nearest to disappearance in the wild.
Butterflies that are only found on high-altitude areas are particularly vulnerable to global warming as they must ascend higher as their habitats become warmer but ultimately run out of space. In the southern part of Spain, the grayling of Nevada and the anomalous blue of Andalusia are among above 40 percent of European endemics (solely present in Europe) facing extinction.
In the Mediterranean region, types such as the highly at-risk grayling of Karpathos are threatened by extreme wildfires and drought.
Meanwhile, in the Arctic region, global heating is resulting in the tree line to shift northward by many meters each year, with bushes encroaching on bog and tundra. Warmer conditions also mean caribou can no longer cross the ice sheets to feed on Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are facing extinction in this area, including the fritillary of Freyja and the Arctic ringlet.
“The greatest living space for all these pollinators is grassland rich in flowers and that is disappearing very fast in the European continent because of all these factors,” said one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many people care now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member states have to halt the drop in pollinating insects by twenty-thirty, and they are going to have to initiate measures. There are landowners who are interested. We hope they can get the incentives that will help them on their way.”
According to the coordinator, there is “readily achievable actions” in terms of action for pollinating species which won’t reduce agricultural output – and may enhance it – such as agricultural producers developing bloom-filled edges around their fields.
the EU’s environment commissioner, described the conservation status of wild bees, butterflies and other pollinators as “critical”.
“Prompt and unified steps is required to address this risk. Together with participating nations, the EU Commission has established an EU-wide monitoring system for pollinating insects based on the EU nature restoration law, which will help to track our development. Now, we need to prioritize execution and collaboration with member states to preserve our pollinating insects,” she said.
The release of the assessments on bees and butterflies follows the initial EU-wide study on hoverflies, a further essential pollinating insect category. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly types in the European continent were threatened with extinction.
