The total of non-managed bee types in European nations confronting disappearance has more than doubled during the previous ten-year period, while the number of threatened butterfly types has nearly doubled.
This dire scenario for essential pollinators was disclosed by scientific assessments for the red list of threatened species, which established that at least one hundred seventy-two bee species out of over 1900 were at risk of extinction in European nations.
The number of butterfly species at risk of extinction in European nations has risen from over thirty-five to over sixty since the previous assessment, conducted over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
In addition to their beauty and cultural significance, pollinators like bees and butterflies are essential supports for our physical condition, our food chains and our financial structures – supporting the produce, vegetables and seeds that feed us,” commented the IUCN’s director general. “The latest assessments of the European red list reveal significant difficulties, with threats increasing for butterfly species and crucial wild bee types.”
The causes of the swift recent drops are the ongoing harm or degradation of living environments caused by intensive agriculture and land abandonment, draining wetlands, overgrazing by livestock, and the use of fertilisers and pesticides including neonicotinoids. The division of habitat friendly to pollinators substantially boosts the danger of extinctions at local level.
Global heating is also shown to be a major threat: 52% of all threatened butterfly species in the European continent are imperilled by the climate crisis – roughly double the number as a ten years ago.
As many as nine out of ten of plants that flower in the European continent require insect pollination, as stated by the wild bee assessment’s lead coordinator. “Regrettably, wild bee colonies are in sharp decrease and are not easily replaceable by managed colonies,” he said. “If wild bees vanish, many non-cultivated plants might be threatened too – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee species, which have an essential part in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, recognized for pollinating trees such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the single type of this genus group in Europe, is now evaluated as severely threatened – the scientific category most akin to dying out in natural habitats.
Butterflies that are solely present on mountain peaks are especially at risk to global warming as they must ascend higher as their living spaces become warmer but ultimately run out of space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean area, species such as the highly at-risk grayling of Karpathos are endangered by severe dry conditions and fires.
At the same time, in the Arctic region, global heating is resulting in the tree line to move north by many meters each year, with scrub invading bog and tundra. Hotter climates also mean caribou can no more cross the ice sheets to feed on Arctic grasslands and maintain them clear. Eight types of butterflies are threatened with extinction in this area, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The greatest habitat for all these pollinators is grassland rich in flowers and that is declining quickly throughout European nations because of all these reasons,” remarked Martin Warren. “The positive thing is that so many individuals are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all participating nations have to turn around the decrease in pollinators by the year 2030, and they are going to have to initiate measures. There are landowners who are involved. It is hoped they can receive the motivations that will support them on their way.”
As stated by the coordinator, there is “low-hanging fruit” in terms of action for pollinating species which will not lower crop yields – and may enhance it – such as agricultural producers creating bloom-filled edges around their fields.
Jessika Roswall, described the protection status of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is necessary to tackle this danger. Together with member states, the European Commission has implemented an Europe-wide observation system for pollinating species based on the European Union nature restoration legislation, which will help to track our development. Now, we need to prioritize implementation and partnership with participating nations to protect our pollinating species,” she said.
The issuance of the evaluations of bees along with butterflies follows the initial European-wide assessment of hoverflies, a further crucial group of pollinators. Issued in 2022, it revealed that over one-third of all hoverfly varieties in the European continent were at risk of extinction.
