The number of non-managed bee varieties in European nations facing disappearance has increased twofold in the last ten years, while the count of endangered butterfly types has close to doubled.
This pressing issue for essential pollinators was revealed by scientific assessments for the IUCN red list, which determined that at least one hundred seventy-two bee species out of over 1900 were threatened with extinction in European nations.
The number of butterfly species threatened with extinction in Europe has increased from over thirty-five to over sixty since the previous assessment, conducted over a decade past. A single species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
“Beyond their aesthetic appeal and cultural significance, pollinators like bees and butterflies are crucial elements for our physical condition, our food chains and our economies – maintaining the fruits, veggies and seeds that nourish us,” stated Grethel Aguilar. “The most recent European red list evaluations reveal serious challenges, with dangers growing for butterflies and essential native bee species.”
The factors of the swift recent drops are the persistent destruction or damage of natural habitats caused by farming intensification and land abandonment, draining of wetlands, excessive grazing by animals, and the application of fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of environments suitable for pollinators significantly raises the danger of disappearances in specific areas.
Global warming is also shown to be a major threat: Over half of all at-risk butterflies in Europe are threatened by the climate crisis – about double the number as a ten years ago.
Up to 90% of flowering plants in the European continent depend on pollination by animals, according to Dr Denis Michez. “Regrettably, wild bee populations are in severe drop and cannot be easily replaced by managed bee colonies,” he said. “If wild bees die out, many non-cultivated plants might be at risk too – of which meadows rich in flowers and attractive orchid varieties are just a handful of illustrations.”
Fifteen types of bumblebee species, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for aiding tree pollination such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species unique to the European continent and the only species of this genus in Europe, is now assessed as critically endangered – the research category nearest to disappearance in the wild.
Butterfly types that are exclusively located on high-altitude areas are especially at risk to global warming as they have to climb upward as their living spaces become more heated but ultimately have no room left. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among more than 40% of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean region, varieties such as the critically endangered grayling of Karpathos are threatened by extreme drought and wildfires.
At the same time, in the Arctic Circle, climate change is resulting in the timberline to shift northward by dozens of meters each year, with underbrush invading bog and tundra. Hotter climates also mean caribou can no longer cross the ice to browse Arctic meadows and maintain them clear. Eight butterfly species are threatened with extinction in this area, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The greatest environment for all these pollinators is grassland rich in flowers and that is declining quickly across European nations because of all these elements,” remarked a lead coordinator for the butterfly 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 decrease in pollinators by the year 2030, and they are going to have to start doing something. There are land holders who are interested. Let’s hope they can get the motivations that will assist them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which will not lower crop yields – and might boost it – such as growers establishing margins rich in flowers around their fields.
the EU’s environment commissioner, portrayed the preservation condition of native bees, butterflies and additional pollinators as “dire”.
“Urgent and collective action is required to confront this threat. Together with member countries, the European Commission has implemented an Europe-wide observation system for pollinating insects based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to prioritize implementation and partnership with member states to preserve our pollinators,” she said.
The issuance of the bee and butterfly assessments follows the pioneering European-wide assessment of hoverflies, another vital pollinator group. Released in twenty-twenty-two, it revealed that over one-third of all hoverfly varieties in European nations were threatened with extinction.
