The total of wild bee types in the European continent facing disappearance has over doubled over the past decade, whereas the count of endangered butterfly species has nearly doubled.
This pressing issue for crucial pollinating species was disclosed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which found that at least 172 bee varieties out of over 1900 were at risk of extinction in European nations.
The number of butterflies at risk of extinction in European nations has increased from thirty-seven to sixty-five since the last study, conducted 14 years ago. A single species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
Apart from their aesthetic appeal and cultural importance, pollinators like bees and butterflies are lifelines for our physical condition, our food chains and our economic systems – maintaining the fruits, veggies and seeds that sustain us,” commented Grethel Aguilar. “The latest European red list assessments reveal major obstacles, with dangers growing for butterfly types and vital native bee types.”
The factors of the swift recent drops are the continuing damage or destruction of living environments caused by farming intensification and abandoned land, wetland drainage, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoids. The breaking up of environments suitable for pollinators significantly raises the danger of disappearances in specific areas.
Global warming is also demonstrated to be a significant danger: 52% of all threatened butterfly types in Europe are threatened by the climate emergency – about twofold the amount as a ten years ago.
As many as ninety percent of plants that flower in the European continent depend on pollination by animals, as stated by Dr Denis Michez. “Unfortunately, wild bee groups are in severe drop and cannot be easily replaced by managed colonies,” he said. “If wild bees disappear, many wild plants might be threatened too – of which flower-rich meadows and beautiful orchid species are just a handful of illustrations.”
15 varieties of bumblebee species, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee types, known for fertilizing trees such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type found only in the continent and the single type of this biological genus in European nations, is now classified as critically at risk – the scientific category closest to disappearance in the wild.
Butterfly species that are solely present on high-altitude areas are particularly vulnerable to climate change as they need to move uphill as their environments become more heated but in the end have no room left. In the southern part of Spain, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (only found in Europe) threatened with extinction.
In the Mediterranean region, varieties such as the critically endangered Karpathos grayling butterfly are endangered by intense wildfires and drought.
At the same time, in the Far North, climate change is causing the forest boundary to move north by many meters each year, with bushes encroaching on bog and tundra. Higher temperatures also mean reindeer can no more cross the ice to graze northern grasslands and prevent them from overgrowing. Eight butterfly species are facing extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The largest habitat for all these pollinating insects is grassland rich in flowers and that is vanishing rapidly throughout European nations because of all these reasons,” stated Martin Warren. “The positive thing is that so many individuals care now and there’s a lot more awareness. Under the EU nature restoration legislation, all member countries have to turn around the drop in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are land holders who are interested. We hope they can obtain the incentives that will help them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of action for pollinating species which won’t reduce agricultural output – and could improve it – such as farmers establishing bloom-filled edges around their farmland.
Jessika Roswall, characterized the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Immediate and joint measures is required to address this danger. In collaboration with member countries, the European Commission has established an Europe-wide observation system for pollinating insects based on the EU nature restoration regulation, which will assist in monitoring our advancement. Now, we need to concentrate on implementation and cooperation with member countries to protect our pollinating insects,” she said.
The release of the bee and butterfly assessments is subsequent to the first Europe-wide evaluation of hoverflies, another vital group of pollinators. Published in 2022, it disclosed that thirty-seven percent of all hoverfly varieties in European nations were at risk of extinction.
