The count of wild bee varieties in the European continent confronting extinction has over doubled over the past decade, while the count of at-risk butterfly types has nearly doubled.
This pressing issue for vital pollinators was unveiled by scientific studies for the IUCN red list, which determined that at least 172 bee types out of 1,928 were facing extinction in Europe.
The count of butterflies threatened with extinction in the European continent has risen from 37 to over sixty since the last study, conducted a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
In addition to their visual charm and cultural significance, pollinators like bees and butterflies are lifelines for our physical condition, our food supplies and our financial structures – supporting the produce, vegetables and seeds that nourish us,” said Grethel Aguilar. “The latest European red list evaluations reveal major obstacles, with dangers growing for butterflies and crucial wild bee varieties.”
The causes of the swift recent drops are the ongoing damage or destruction of living environments caused by intensive agriculture and deserted farmland, wetland drainage, overgrazing by livestock, and the use of fertilisers and pesticides including neonicotinoid pesticides. The division of habitat friendly to pollinators significantly raises the danger of extinctions at local level.
Global heating is also demonstrated to be a significant danger: Fifty-two percent of all threatened butterflies in Europe are endangered by the climate crisis – roughly twice as many as a ten years ago.
As many as ninety percent of plants that flower in Europe rely on pollination by animals, as per the wild bee assessment’s lead coordinator. “Unfortunately, native bee groups are in sharp decrease and cannot be easily replaced by managed bee colonies,” he said. “If native bees vanish, many non-cultivated plants might be threatened too – of which bloom-filled grasslands and beautiful orchid species are just a few examples.”
15 varieties of bumblebees, which have an essential part in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, known for aiding tree pollination such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the single type of this biological genus in the European continent, is now assessed as critically at risk – the scientific category most akin to extinction in the wild.
Butterfly types that are only found on high-altitude areas are especially at risk to global heating as they have to climb upward as their habitats become warmer but in the end have no room left. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean area, species such as the severely threatened grayling of Karpathos are endangered by extreme wildfires and drought.
Meanwhile, in the Arctic region, global warming is leading to the tree line to advance northwards by many meters each year, with bushes encroaching on marsh and tundra. Higher temperatures also mean reindeer can no longer cross the ice to browse northern grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The biggest environment for all these pollinators is bloom-filled grassy areas and that is declining quickly throughout the European continent because of all these factors,” remarked a lead coordinator for the butterfly assessment. “The good news is that so many people are aware now and there’s a lot more awareness. Under the European Union nature restoration law, all member countries have to halt the decrease in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are property owners who are interested. It is hoped they can get the motivations that will support them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of measures for pollinating insects which will not decrease agricultural output – and could improve it – such as agricultural producers establishing margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, characterized the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is required to confront this risk. In collaboration with member states, the EU Commission has implemented an Europe-wide tracking system for pollinating insects based on the EU nature restoration law, which will aid in following our progress. Now, we need to prioritize application and partnership with member states to preserve our pollinators,” she said.
The release of the evaluations of bees along with butterflies comes after the initial EU-wide study on hoverflies, an additional crucial group of pollinators. Issued in 2022, it revealed that thirty-seven percent of all hoverfly species in the European continent were threatened with extinction.
