The count of native bee species in European nations confronting extinction has increased twofold in the last ten years, and the total of at-risk butterfly species has nearly doubled.
This pressing issue for essential pollinators was unveiled by scientific assessments for the IUCN red list, which established that at least one hundred seventy-two bee varieties out of nearly two thousand were facing extinction in European nations.
The total of butterfly types facing extinction in European nations has risen from over thirty-five to 65 since the last study, performed over a decade past. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
Apart from their aesthetic appeal and cultural significance, pollinators like bees and butterfly species are essential supports for our well-being, our food chains and our economic systems – maintaining the fruits, veggies and seeds that nourish us,” stated Grethel Aguilar. “The most recent European red list assessments reveal major obstacles, with threats mounting for butterfly types and crucial non-managed bee varieties.”
The reasons of the swift recent drops are the continuing destruction or damage of living environments caused by intensive agriculture and abandoned land, draining wetlands, livestock overgrazing, and the application of pesticides and fertilisers including neonicotinoid pesticides. The breaking up of environments suitable for pollinators greatly increases the risk of local extinctions.
Climate change is also revealed to be a significant danger: Fifty-two percent of all at-risk butterflies in European nations are threatened by the climate crisis – about double the number as a ten years ago.
Up to nine out of ten of blooming plants in European nations depend on insect pollination, according to the lead coordinator of the wild bee assessment. “Regrettably, native bee groups are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees die out, many non-cultivated plants might be threatened too – of which bloom-filled grasslands and lovely orchid types are just a handful of illustrations.”
Fifteen species of bumblebee species, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, recognized for aiding tree pollination such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the only species of this biological genus in European nations, is now assessed as severely threatened – the scientific classification most akin to disappearance in the wild.
Butterfly types that are solely present on high-altitude areas are particularly vulnerable to global warming as they have to climb upward as their living spaces become hotter but ultimately have no room left. In Spain’s southern region, the grayling of Nevada and the anomalous blue of Andalusia are among more than 40% of species endemic to Europe (only found in Europe) at risk of extinction.
In the Mediterranean area, species such as the severely threatened grayling of Karpathos are imperilled by extreme dry conditions and fires.
In the meantime, in the Arctic Circle, global heating is resulting in the forest boundary to move north by dozens of meters each year, with bushes invading marsh and tundra. Hotter climates also mean caribou can not anymore cross the ice to feed on Arctic meadows and keep them open. Eight types of butterflies are facing extinction in this zone, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The largest living space for all these pollinating insects is bloom-filled grassy areas and that is disappearing very fast throughout the European continent because of all these reasons,” stated one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens care now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to reverse the decline in pollinating species by 2030, and they are going to have to begin taking action. There are landowners who are engaged. We hope they can get the incentives that will support them on their way.”
As per the coordinator, there is “easy opportunities” in terms of action for pollinating insects which won’t reduce food production – and may enhance it – such as farmers creating bloom-filled edges around their cultivated areas.
Jessika Roswall, described the protection status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Urgent and collective action is necessary to confront this threat. In collaboration with member states, the EU Commission has implemented an European Union-wide monitoring system for pollinating species based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to concentrate on application and cooperation with member states to protect our pollinating insects,” she said.
The publication of the assessments on bees and butterflies is subsequent to the initial Europe-wide assessment of hoverflies, a further crucial pollinator group. Released in 2022, it disclosed that 37% of all hoverfly varieties in Europe were threatened with extinction.
