The total of wild bee types in European nations confronting disappearance has over doubled in the last ten years, and the number of threatened butterfly types has close to doubled.
This dire scenario for vital pollinators was unveiled by research studies for the red list of threatened species, which determined that at least 172 bee types out of over 1900 were at risk of extinction in Europe.
The total of butterfly types threatened with extinction in European nations has risen from over thirty-five to sixty-five since the previous assessment, carried out over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
Apart from their visual charm and cultural significance, pollinating insects like bees and butterfly species are crucial elements for our physical condition, our food systems and our economic systems – sustaining the produce, vegetables and seeds that feed us,” stated the IUCN’s director general. “The latest European red list evaluations reveal serious challenges, with threats mounting for butterflies and essential non-managed bee varieties.”
The reasons of the quick recent decreases are the continuing harm or degradation of natural habitats caused by farming intensification and abandoned land, wetland drainage, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoid pesticides. The breaking up of habitat friendly to pollinators significantly raises the danger of extinctions at local level.
Climate change is also demonstrated to be a primary risk: 52% of all endangered butterflies in the European continent are threatened by the climate emergency – about double the number as a previous decade.
Nearly ninety percent of plants that flower in Europe rely on insect pollination, as stated by the lead coordinator of the wild bee assessment. “Unfortunately, non-managed bee groups are in drastic decline and cannot readily be substituted by managed bee colonies,” he said. “If wild bees die out, many wild plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a few examples.”
Fifteen types of bumblebee types, which perform a vital function in fertilizing peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for fertilizing trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the single type of this biological genus in the European continent, is now assessed as critically at risk – the scientific classification most akin to extinction in the wild.
Butterfly types that are exclusively located on high-altitude areas are particularly vulnerable to global warming as they have to climb upward as their environments become warmer but eventually exhaust available space. In the southern part of Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of species endemic to Europe (solely present in Europe) at risk of extinction.
In the Mediterranean region, species such as the critically endangered Karpathos grayling butterfly are endangered by intense wildfires and drought.
At the same time, in the Arctic Circle, global heating is resulting in the forest boundary to shift northward by many meters each year, with scrub encroaching on bog and tundra. Higher temperatures also mean reindeer can not anymore cross the frozen water to feed on northern grasslands and prevent them from overgrowing. Eight butterfly species are at risk of extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.
“The biggest environment for all these pollinating insects is grassland rich in flowers and that is vanishing rapidly in Europe because of all these factors,” stated Martin Warren. “The positive thing is that so many citizens care now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member states have to turn around the drop in pollinating species by twenty-thirty, and they are going to have to start doing something. There are land holders who are involved. It is hoped they can receive the motivations that will help them on their way.”
As per the coordinator, there is “readily achievable actions” in terms of measures for pollinating insects which won’t reduce food production – and could improve it – such as growers establishing margins rich in flowers around their fields.
the EU’s environment commissioner, characterized the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Immediate and joint measures is required to confront this risk. Together with member countries, the EU Commission has implemented an European Union-wide observation system for pollinating insects based on the EU nature restoration regulation, which will assist in monitoring our advancement. Now, we need to concentrate on implementation and collaboration with member states to preserve our pollinators,” she said.
The publication of the evaluations of bees along with butterflies comes after the initial EU-wide study on hoverflies, an additional vital group of pollinators. Issued in 2022, it disclosed that over one-third of all hoverfly types in Europe were facing extinction.
