The number of non-managed bee types in European nations facing disappearance has increased twofold in the last ten years, and the total of at-risk butterfly types has nearly doubled.
This dire scenario for crucial pollinators was disclosed by research studies for the red list of threatened species, which found that at least over 170 bee varieties out of 1,928 were facing extinction in European nations.
The number of butterfly species facing extinction in Europe has grown from 37 to 65 since the previous assessment, carried out a decade and a half ago. A single species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their aesthetic appeal and cultural value, pollinators like bees along with butterflies are crucial elements for our physical condition, our food supplies and our financial structures – supporting the produce, vegetables and seeds that feed us,” stated Grethel Aguilar. “The newest European red list assessments reveal serious challenges, with risks growing for butterfly species and crucial non-managed bee types.”
The causes of the swift recent drops are the persistent harm or degradation of natural habitats caused by farming intensification and deserted farmland, draining of wetlands, overgrazing by livestock, and the application of fertilisers and pesticides including neonicotinoids. The breaking up of habitat friendly to pollinators significantly raises the danger of extinctions at local level.
Global heating is also revealed to be a significant danger: 52% of all at-risk butterfly types in the European continent are endangered by the climate change crisis – roughly twofold the amount as a decade ago.
As many as nine out of ten of blooming plants in European nations rely on animal pollination, as stated by Dr Denis Michez. “Sadly, native bee colonies are in severe drop and cannot readily be substituted by domesticated hives,” he said. “If wild bees disappear, many non-cultivated plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a handful of illustrations.”
Fifteen species of bumblebees, which have an essential part in fertilizing peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, known for pollinating trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee unique to the continent and the only species of this biological genus in European nations, is now evaluated as critically endangered – the scientific category nearest to dying out in natural habitats.
Butterfly species that are solely present on mountain peaks are especially at risk to global warming as they need to move uphill as their habitats become hotter but eventually exhaust available space. In the southern part of Spain, the grayling of Nevada and the anomalous blue of Andalusia are among over forty percent of types unique to Europe (solely present in Europe) facing extinction.
In the Mediterranean, types such as the severely threatened Karpathos grayling butterfly are endangered by severe wildfires and drought.
At the same time, in the Far North, global warming is resulting in the timberline to advance northwards by dozens of meters each year, with scrub encroaching on wetlands and tundra. Warmer conditions also mean reindeer can not anymore cross the frozen water to browse northern grasslands and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The biggest environment for all these pollinators is bloom-filled grassy areas and that is disappearing very fast in the European continent because of all these elements,” remarked one of the lead coordinators of the butterflies assessment. “The good news is that so many individuals are aware now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all participating nations have to reverse the drop in pollinators by 2030, and they are going to have to begin taking action. There are landowners who are interested. It is hoped they can get the motivations that will support them on their way.”
According to Martin Warren, there is “easy opportunities” in terms of action for pollinators which will not decrease crop yields – and could improve it – such as farmers establishing flower-rich margins around their fields.
the EU’s environment commissioner, characterized the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Urgent and collective action is required to tackle this risk. Together with member states, the EU Commission has implemented an EU-wide observation system for pollinators based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to prioritize implementation and collaboration with member states to safeguard our pollinating species,” she said.
The release of the bee and butterfly assessments is subsequent to the initial Europe-wide evaluation of hoverflies, another crucial group of pollinators. Issued in 2022, it showed that 37% of all hoverfly types in Europe were facing extinction.
