The count of non-managed bee species in Europe facing dying out has increased twofold in the last ten years, whereas the count of at-risk butterfly has nearly doubled.
This pressing issue for crucial pollinating species was revealed by scientific assessments for the IUCN red list, which determined that at least 172 bee varieties out of over 1900 were threatened with extinction in European nations.
The total of butterflies at risk of extinction in European nations has risen from thirty-seven to over sixty since the earlier research, carried out over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural value, pollinators like bees along with butterflies are crucial elements for our well-being, our food systems and our economies – supporting the fruits, vegetables and seeds that feed us,” stated Grethel Aguilar. “The most recent European red list evaluations reveal significant difficulties, with threats increasing for butterflies and essential non-managed bee species.”
The factors of the quick recent decreases are the continuing damage or destruction of living environments caused by agricultural intensification and abandoned land, draining wetlands, excessive grazing by animals, and the application of chemical fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of pollinator-friendly habitat substantially boosts the risk of extinctions at local level.
Global heating is also shown to be a significant danger: Over half of all at-risk butterfly species in the European continent are endangered by the climate change crisis – approximately twice as many as a decade ago.
As many as ninety percent of flowering plants in European nations depend on animal pollination, according to the lead coordinator of the wild bee assessment. “Unfortunately, non-managed bee groups are in severe drop and cannot readily be substituted by domesticated hives,” he said. “If wild bees die out, many native plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a handful of illustrations.”
Fifteen species of bumblebee species, which play a crucial role in pollinating crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee types, known for fertilizing trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species unique to the continent and the only species of this biological genus in European nations, is now assessed as severely threatened – the scientific classification nearest to dying out in natural habitats.
Butterfly species that are only found on mountain peaks are especially at risk to global heating as they must ascend higher as their environments become warmer but in the end run out of space. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among over forty percent of types unique to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean region, types such as the highly at-risk grayling of Karpathos are endangered by intense drought and wildfires.
Meanwhile, in the Arctic region, global warming is causing the tree line to move north by dozens of meters each year, with bushes invading marsh and tundra. Warmer conditions also mean reindeer can no longer cross the ice to browse Arctic grasslands and keep them open. 8 butterfly varieties are threatened with extinction in this area, including the fritillary of Freyja and the ringlet of the Arctic.
“The greatest living space for all these pollinators is bloom-filled grassy areas and that is vanishing rapidly across the European continent because of all these reasons,” 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 understanding. Under the EU’s nature restoration regulation, all participating nations have to reverse the drop in pollinating insects by the year 2030, and they are going to have to begin taking action. There are property owners who are involved. Let’s hope they can receive the encouragements that will help them on their way.”
According to the coordinator, there is “easy opportunities” in terms of action for pollinating species which will not decrease food production – and may enhance it – such as growers establishing flower-rich margins around their fields.
the EU’s environment commissioner, portrayed the protection status of wild bees, butterflies and other pollinators as “dire”.
“Prompt and unified steps is needed to tackle this danger. Along with member countries, the European Commission has implemented an European Union-wide observation system for pollinating species based on the European Union nature restoration legislation, which will aid in following our advancement. Now, we need to concentrate on application and partnership with participating nations to safeguard our pollinators,” she said.
The publication of the bee and butterfly assessments is subsequent to the pioneering Europe-wide evaluation of hoverflies, another crucial pollinator group. Published in 2022, it revealed that thirty-seven percent of all hoverfly species in Europe were threatened with extinction.
