The number of wild bee types in Europe experiencing extinction has more than doubled over the past decade, and the count of at-risk butterfly types has close to doubled.
This critical situation for essential pollinating species was unveiled by research studies for the IUCN red list, which established that at least 172 bee varieties out of over 1900 were at risk of extinction in European nations.
The number of butterfly species at risk of extinction in Europe has risen from over thirty-five to sixty-five since the last study, conducted a decade and a half ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
“Beyond their beauty and cultural importance, pollinating species like bees and butterflies are essential supports for our well-being, our food supplies and our economies – supporting the fruits, veggies and seeds that nourish us,” stated the IUCN director general. “The most recent assessments of the European red list reveal serious challenges, with threats increasing for butterfly types and essential native bee varieties.”
The causes of the rapid recent declines are the continuing damage or destruction of habitats caused by farming intensification and land abandonment, draining of wetlands, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoid pesticides. The division of habitat friendly to pollinators greatly increases the risk of extinctions at local level.
Global heating is also revealed to be a primary risk: Fifty-two percent of all at-risk butterflies in Europe are imperilled by the climate change crisis – about twice as many as a ten years ago.
Up to ninety percent of flowering plants in Europe require insect pollination, according to the lead coordinator of the wild bee assessment. “Sadly, native bee populations are in severe drop and are not easily replaceable by managed colonies,” he said. “If native bees die out, many native plants might be in danger as well – of which bloom-filled grasslands and lovely orchid types are just a handful of illustrations.”
Fifteen species of bumblebee species, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for pollinating trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the only species of this genus group in Europe, is now evaluated as critically at risk – the research category closest to dying out in natural habitats.
Butterfly types that are solely present on high-altitude areas are highly susceptible to climate change as they have to climb upward as their environments become hotter but in the end exhaust available space. In the southern part of Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among more than 40% of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean area, types such as the severely threatened Karpathos grayling are imperilled by severe dry conditions and fires.
At the same time, in the Far North, climate change is causing the forest boundary to move north by dozens of meters each year, with scrub encroaching on bog and tundra. Higher temperatures also mean caribou can not anymore cross the frozen water to browse northern grasslands and maintain them clear. Eight butterfly species are threatened with extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The biggest environment for all these pollinating species is bloom-filled grassy areas and that is declining quickly in the European continent because of all these factors,” stated one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many individuals care now and there’s a lot more consciousness. Under the European Union nature restoration law, all participating nations have to reverse the drop in pollinating species by the year 2030, and they are going to have to initiate measures. There are property owners who are interested. Let’s hope they can obtain the incentives that will help them on their way.”
As per Warren, there is “readily achievable actions” in terms of action for pollinators which will not decrease food production – and may enhance it – such as agricultural producers establishing flower-rich margins around their farmland.
the EU’s environment commissioner, characterized the preservation condition of wild bees, butterflies and other pollinators as “dire”.
“Prompt and unified steps is needed to confront this danger. Together with participating nations, the Commission of the European Union has put in place an European Union-wide observation system for pollinating species based on the EU nature restoration law, which will help to track our advancement. Now, we need to prioritize application and collaboration with member countries to preserve our pollinators,” she said.
The issuance of the bee and butterfly assessments is subsequent to the pioneering European-wide study on hoverflies, a further essential group of pollinators. Published in twenty-twenty-two, it showed that over one-third of all hoverfly species in Europe were at risk of extinction.
