The total of wild bee types in Europe confronting extinction has more than doubled in the last ten years, and the total of endangered butterfly types has close to doubled.
This pressing issue for essential pollinating species was disclosed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which established that at least over 170 bee varieties out of over 1900 were at risk of extinction in the European continent.
The count of butterfly species at risk of extinction in the European continent has grown from over thirty-five to sixty-five since the last study, conducted a decade and a half ago. One species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
“Beyond their visual charm and cultural significance, pollinating species like bees and butterflies are crucial elements for our health, our food systems and our economic systems – maintaining the fruits, veggies and seeds that sustain us,” stated Grethel Aguilar. “The newest assessments of the European red list reveal major obstacles, with risks growing for butterflies and essential non-managed bee varieties.”
The reasons of the quick recent decreases are the persistent destruction or damage of habitats caused by intensive agriculture and land abandonment, draining of wetlands, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoids. The division of habitat friendly to pollinators substantially boosts the threat of extinctions at local level.
Global warming is also demonstrated to be a major threat: 52% of all at-risk butterflies in European nations are imperilled by the climate crisis – about twice as many as a previous decade.
Nearly nine out of ten of plants that flower in European nations depend on animal pollination, according to the wild bee assessment’s lead coordinator. “Unfortunately, native bee colonies are in sharp decrease and are not easily replaceable by managed bee colonies,” he said. “If native bees disappear, many native plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”
Fifteen species of bumblebees, which play a crucial role in fertilizing crops such as peas, beans, peanuts and clover, and 14 species of cellophane bees, famous for fertilizing trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the continent and the single type of this genus group in the European continent, is now classified as critically endangered – the scientific category most akin to disappearance in the wild.
Butterflies that are exclusively located on mountain tops are particularly vulnerable to climate change as they need to move uphill as their environments become more heated but in the end exhaust available space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among more than 40% of European endemics (exclusive to Europe) at risk of extinction.
In the Mediterranean, types such as the highly at-risk Karpathos grayling butterfly are threatened by severe wildfires and drought.
Meanwhile, in the Arctic region, global warming is causing the forest boundary to shift northward by tens of metres each year, with scrub taking over wetlands and tundra. Higher temperatures also mean caribou can no more cross the ice to graze Arctic grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this zone, including Freyja’s fritillary and the Arctic ringlet.
“The greatest living space for all these pollinating species is bloom-filled grassy areas and that is declining quickly throughout European nations because of all these elements,” said 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 awareness. Under the EU nature restoration legislation, all member countries have to halt the drop in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are property owners who are involved. It is hoped they can obtain the motivations that will help them on their way.”
As per Martin Warren, there is “low-hanging fruit” in terms of action for pollinating insects which will not lower crop yields – and might boost it – such as agricultural producers creating margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, described the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Prompt and unified steps is necessary to address this threat. Along with member states, the Commission of the European Union has established an European Union-wide tracking system for pollinating species based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to focus on execution and partnership with participating nations to preserve our pollinating species,” she said.
The issuance of the bee and butterfly assessments is subsequent to the first EU-wide study on hoverflies, an additional crucial pollinating insect category. Issued in 2022, it showed that thirty-seven percent of all hoverfly varieties in Europe were facing extinction.
