The count of non-managed bee species in the European continent experiencing extinction has increased twofold in the last ten years, and the number of at-risk butterfly species has close to doubled.
This dire scenario for vital pollinating species was disclosed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least one hundred seventy-two bee species out of nearly two thousand were threatened with extinction in Europe.
The total of butterflies threatened with extinction in Europe has risen from 37 to over sixty since the earlier research, conducted a decade and a half ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
Apart from their visual charm and cultural significance, pollinating species like bees and butterflies are essential supports for our health, our food supplies and our economies – maintaining the produce, vegetables and seeds that sustain us,” stated the IUCN director general. “The newest assessments of the European red list reveal major obstacles, with risks growing for butterfly types and essential non-managed bee varieties.”
The factors of the rapid recent declines are the persistent destruction or damage of habitats caused by agricultural intensification and abandoned land, wetland drainage, livestock overgrazing, and the utilization of chemical fertilisers and pesticides including neonicotinoid chemicals. The division of pollinator-friendly habitat greatly increases the risk of disappearances in specific areas.
Global heating is also shown to be a significant danger: Fifty-two percent of all endangered butterflies in Europe are imperilled by the climate change crisis – roughly twofold the amount as a decade ago.
Nearly nine out of ten of blooming plants in the European continent require insect pollination, as stated by the wild bee assessment’s lead coordinator. “Regrettably, native bee populations are in drastic decline and cannot be easily replaced by managed colonies,” he said. “If non-managed bees die out, many native plants might be at risk too – of which bloom-filled grasslands and attractive orchid varieties are just a handful of illustrations.”
Fifteen types of bumblebees, which have an essential part in pollinating legumes like peas, beans, peanuts and clover, and 14 species of cellophane bees, known for fertilizing trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the mainland and the only species of this biological genus in European nations, is now evaluated as critically endangered – the research category closest to dying out in natural habitats.
Butterfly types that are exclusively located on mountain tops are particularly vulnerable to global heating as they must ascend higher as their habitats become warmer but in the end run out of space. In southern Spain, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (only found in Europe) at risk of extinction.
In the Mediterranean region, species such as the highly at-risk Karpathos grayling butterfly are endangered by extreme drought and wildfires.
In the meantime, in the Arctic region, global heating is causing the tree line to move north by tens of metres each year, with bushes encroaching on wetlands and tundra. Hotter climates also mean Arctic deer can no longer cross the ice to graze northern grasslands and maintain them clear. Eight butterfly species are facing extinction in this area, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The largest environment for all these pollinators is grassland rich in flowers and that is vanishing rapidly across Europe because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens care now and there’s a lot more understanding. Under the EU nature restoration legislation, all member states have to turn around the drop in pollinators by 2030, and they are going to have to start doing something. There are land holders who are engaged. We hope they can obtain the motivations that will assist them on their way.”
As per the coordinator, there is “readily achievable actions” in terms of measures for pollinating insects which won’t reduce agricultural output – and may enhance it – such as growers establishing flower-rich margins around their farmland.
the EU’s environment commissioner, portrayed the conservation status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Immediate and joint measures is necessary to address this danger. In collaboration with member states, the European Commission has put in place an Europe-wide observation system for pollinators based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to concentrate on execution and collaboration with member states to preserve our pollinating insects,” she said.
The publication of the evaluations of bees along with butterflies follows the initial European-wide evaluation of hoverflies, an additional essential pollinator group. Issued in twenty-twenty-two, it revealed that over one-third of all hoverfly types in European nations were at risk of extinction.
