The number of wild bee species in Europe facing extinction has increased twofold over the past decade, while the number of at-risk butterfly species has close to doubled.
This pressing issue for essential pollinating insects was unveiled by scientific assessments for the red list of threatened species, which found that at least 172 bee types out of nearly two thousand were facing extinction in European nations.
The number of butterfly species at risk of extinction in Europe has grown from thirty-seven to 65 since the previous assessment, performed a decade and a half ago. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
Apart from their beauty and cultural significance, pollinators like bees along with butterflies are lifelines for our well-being, our food supplies and our economies – supporting the fruits, vegetables and seeds that feed us,” said Grethel Aguilar. “The newest European red list assessments reveal serious challenges, with dangers mounting for butterflies and vital non-managed bee types.”
The factors of the quick recent decreases are the continuing harm or degradation of habitats caused by intensive agriculture and land abandonment, draining wetlands, overgrazing by livestock, and the use of pesticides and fertilisers including neonicotinoids. The breaking up of pollinator-friendly habitat substantially boosts the danger of extinctions at local level.
Climate change is also revealed to be a primary risk: Fifty-two percent of all threatened butterfly species in the European continent are imperilled by the climate change crisis – about twice as many as a ten years ago.
Up to nine out of ten of blooming plants in Europe rely on insect pollination, according to Dr Denis Michez. “Regrettably, non-managed bee populations are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees disappear, many non-cultivated plants might be in danger as well – of which bloom-filled grasslands and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebee types, which play a crucial role in fertilizing legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, famous for pollinating trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species found only in the continent and the single type of this genus group in European nations, is now assessed as severely threatened – the research category nearest to extinction in the wild.
Butterflies that are solely present on high-altitude areas are especially at risk to global heating as they need to move uphill as their habitats become more heated but in the end exhaust available space. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean, varieties such as the highly at-risk Karpathos grayling butterfly are threatened by severe dry conditions and fires.
In the meantime, in the Arctic region, global heating is leading to the tree line to advance northwards by tens of metres each year, with underbrush taking over bog and tundra. Warmer conditions also mean reindeer can not anymore cross the ice to graze northern grasslands and maintain them clear. 8 butterfly varieties are threatened with extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The greatest environment for all these pollinators is grassland rich in flowers and that is declining quickly throughout European nations because of all these elements,” said a lead coordinator for the butterfly assessment. “The good news is that so many individuals are concerned now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all member countries have to turn around the decline in pollinators by 2030, and they are going to have to initiate measures. There are land holders who are engaged. We hope they can receive the incentives that will help them on their way.”
As per Warren, there is “readily achievable actions” in terms of measures for pollinating insects which won’t reduce agricultural output – and could improve it – such as farmers creating flower-rich margins around their cultivated areas.
the EU’s environment commissioner, portrayed the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is necessary to tackle this threat. In collaboration with participating nations, the Commission of the European Union has put in place an European Union-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will help to track our advancement. Now, we need to prioritize implementation and cooperation with member states to protect our pollinators,” she said.
The issuance of the assessments on bees and butterflies is subsequent to the pioneering European-wide study on hoverflies, an additional crucial pollinating insect category. Released in twenty-twenty-two, it revealed that 37% of all hoverfly types in Europe were threatened with extinction.
