The count of wild bee varieties in the European continent confronting disappearance has over doubled in the last ten years, whereas the count of threatened butterfly types has close to doubled.
This critical situation for crucial pollinating insects was revealed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which established that at least 172 bee types out of nearly two thousand were facing extinction in European nations.
The count of butterflies facing extinction in Europe has grown from 37 to 65 since the earlier research, conducted a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
In addition to their beauty and cultural significance, pollinators like bees and butterflies are crucial elements for our well-being, our food supplies and our economic systems – supporting the fruits, veggies and seeds that sustain us,” commented the IUCN director general. “The latest European red list evaluations reveal significant difficulties, with threats increasing for butterfly types and essential native bee species.”
The causes of the swift recent drops are the continuing harm or degradation of living environments caused by farming intensification and land abandonment, draining wetlands, livestock overgrazing, and the use of chemical fertilisers and pesticides including neonicotinoid chemicals. The division of pollinator-friendly habitat significantly raises the threat of local extinctions.
Global heating is also shown to be a primary risk: Fifty-two percent of all threatened butterfly species in Europe are endangered by the climate change crisis – roughly double the number as a previous decade.
As many as nine out of ten of flowering plants in Europe depend on pollination by animals, as per the lead coordinator of the wild bee assessment. “Unfortunately, wild bee groups are in drastic decline and are not easily replaceable by managed bee colonies,” he said. “If native bees die out, many non-cultivated plants might be at risk too – of which meadows rich in flowers and lovely orchid types are just a few examples.”
Fifteen types of bumblebee species, which perform a vital function in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, famous for pollinating trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the only species of this biological genus in European nations, is now assessed as severely threatened – the scientific classification most akin to disappearance in the wild.
Butterfly species that are only found on mountain peaks are highly susceptible to global heating as they have to climb upward as their living spaces become more heated but eventually have no room left. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among over forty percent of European endemics (only found in Europe) threatened with extinction.
In the Mediterranean, species such as the critically endangered Karpathos grayling butterfly are threatened by intense dry conditions and fires.
At the same time, in the Far North, global heating is resulting in the tree line to advance northwards by dozens of meters each year, with bushes taking over bog and tundra. Higher temperatures also mean Arctic deer can no longer cross the ice to browse northern grasslands and prevent them from overgrowing. Eight butterfly species are at risk of extinction in this area, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The greatest habitat for all these pollinating insects is flower-rich grassland and that is disappearing very fast throughout European nations because of all these reasons,” said one of the lead coordinators of the butterflies assessment. “The good news is that so many citizens care now and there’s a lot more consciousness. Under the EU nature restoration legislation, all participating nations have to reverse the decline in pollinators by the year 2030, and they are going to have to initiate measures. There are property owners who are engaged. We hope they can get the motivations that will support them on their way.”
According to the coordinator, there is “readily achievable actions” in terms of action for pollinating species which will not lower agricultural output – and might boost it – such as growers developing margins rich in flowers around their farmland.
Jessika Roswall, portrayed the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is required to tackle this threat. Together with member countries, the Commission of the European Union has implemented an EU-wide monitoring system for pollinating species based on the EU nature restoration regulation, which will aid in following our development. Now, we need to focus on application and partnership with participating nations to preserve our pollinators,” she said.
The release of the assessments on bees and butterflies is subsequent to the pioneering Europe-wide evaluation of hoverflies, a further essential pollinator group. Published in 2022, it revealed that thirty-seven percent of all hoverfly species in European nations were at risk of extinction.
