The number of non-managed bee varieties in European nations experiencing extinction has increased twofold during the previous ten-year period, whereas the count of at-risk butterfly species has close to doubled.
This pressing issue for vital pollinators was unveiled by research studies for the IUCN red list, which determined that at least over 170 bee species out of 1,928 were threatened with extinction in European nations.
The total of butterflies facing extinction in the European continent has increased from thirty-seven to sixty-five since the previous assessment, performed a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
In addition to their visual charm and cultural importance, pollinating insects like bees along with butterflies are lifelines for our physical condition, our food systems and our economic systems – sustaining the fruits, vegetables and seeds that sustain us,” said the IUCN director general. “The newest European red list evaluations reveal major obstacles, with dangers increasing for butterfly types and vital wild bee species.”
The causes of the swift recent drops are the continuing harm or degradation of habitats caused by intensive agriculture and abandoned land, draining wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoid pesticides. The breaking up of environments suitable for pollinators significantly raises the threat of extinctions at local level.
Climate change is also revealed to be a primary risk: 52% of all at-risk butterfly species in the European continent are imperilled by the climate change crisis – roughly twofold the amount as a previous decade.
As many as ninety percent of flowering plants in European nations depend on insect pollination, as stated by the lead coordinator of the wild bee assessment. “Sadly, native bee colonies are in sharp decrease and are not easily replaceable by managed colonies,” he said. “If native bees die out, many native plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebee species, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and fourteen varieties 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 species found only in the European continent and the only species of this biological genus in the European continent, is now assessed as critically endangered – the scientific category most akin to extinction in the wild.
Butterflies that are exclusively located on high-altitude areas are highly susceptible to global heating as they have to climb upward as their living spaces become more heated but in the end run out of space. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean, species such as the severely threatened Karpathos grayling butterfly are imperilled by extreme drought and wildfires.
At the same time, in the Arctic Circle, global heating is causing the timberline to advance northwards by tens of metres each year, with bushes taking over bog and tundra. Warmer conditions also mean Arctic deer can not anymore cross the ice sheets to browse Arctic meadows and maintain them clear. Eight butterfly species are at risk of extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The biggest habitat for all these pollinators is grassland rich in flowers and that is disappearing very fast in European nations because of all these reasons,” stated a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many citizens are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all participating nations have to halt the decline in pollinators by 2030, and they are going to have to start doing something. There are land holders who are interested. We hope they can get the encouragements that will support them on their way.”
According to the coordinator, there is “readily achievable actions” in terms of steps for pollinating species which will not decrease food production – and could improve it – such as growers establishing bloom-filled edges around their farmland.
EU commissioner for environment, described the preservation condition of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Prompt and unified steps is required to tackle this risk. Together with participating nations, the EU Commission has implemented an EU-wide tracking system for pollinating species based on the EU nature restoration regulation, which will help to track our development. Now, we need to concentrate on application and cooperation with member states to safeguard our pollinating insects,” she said.
The release of the bee and butterfly assessments follows the pioneering Europe-wide study on hoverflies, an additional crucial pollinator group. Published in 2022, it revealed that thirty-seven percent of all hoverfly species in European nations were at risk of extinction.
