The count of wild bee species in the European continent confronting disappearance has more than doubled in the last ten years, whereas the count of threatened butterfly species has close to doubled.
This critical situation for vital pollinating insects was revealed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least 172 bee varieties out of nearly two thousand were threatened with extinction in the European continent.
The count of butterfly types facing extinction in Europe has risen from thirty-seven to over sixty since the earlier research, conducted over a decade past. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural value, pollinators like bees and butterfly species are lifelines for our health, our food chains and our economic systems – maintaining the produce, vegetables and seeds that sustain us,” stated Grethel Aguilar. “The latest assessments of the European red list reveal significant difficulties, with risks growing for butterflies and crucial non-managed bee types.”
The causes of the quick recent decreases are the continuing damage or destruction of natural habitats caused by farming intensification and land abandonment, draining wetlands, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoids. The division of environments suitable for pollinators significantly raises the threat of disappearances in specific areas.
Global warming is also demonstrated to be a primary risk: 52% of all endangered butterfly species in Europe are imperilled by the climate crisis – roughly double the number as a decade ago.
Nearly ninety percent of plants that flower in Europe depend on animal pollination, according to the lead coordinator of the wild bee assessment. “Regrettably, non-managed bee groups are in sharp decrease and cannot be easily replaced by domesticated hives,” he said. “If native bees die out, many native plants might be in danger as well – of which flower-rich meadows and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebees, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and 14 types of cellophane bee species, known for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type found only in the continent and the only species of this genus group in Europe, is now assessed as severely threatened – the scientific category most akin to disappearance in the wild.
Butterflies that are only found on mountain peaks are especially at risk to global warming as they need to move uphill as their environments become more heated but eventually have no room left. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among more than 40% of types unique to Europe (only found in Europe) facing extinction.
In the Mediterranean region, types such as the highly at-risk Karpathos grayling butterfly are imperilled by severe wildfires and drought.
At the same time, in the Arctic region, global warming is resulting in the forest boundary to shift northward by many meters each year, with scrub taking over marsh and tundra. Higher temperatures also mean Arctic deer can no longer cross the frozen water to browse Arctic meadows and maintain them clear. 8 butterfly varieties are threatened with extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The biggest habitat for all these pollinating species is flower-rich grassland and that is vanishing rapidly in Europe because of all these elements,” remarked one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are concerned now and there’s a lot more consciousness. Under the European Union nature restoration law, all participating nations have to turn around the decrease in pollinators by the year 2030, and they are going to have to initiate measures. There are landowners who are involved. It is hoped they can obtain the encouragements that will assist them on their way.”
As stated by Martin Warren, there is “low-hanging fruit” in terms of action for pollinating insects which won’t reduce agricultural output – and might boost it – such as farmers establishing margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, characterized the conservation status of wild bees, butterflies and other pollinators as “severe”.
“Prompt and unified steps is required to tackle this risk. In collaboration with member states, the Commission of the European Union has established an European Union-wide monitoring system for pollinating insects based on the EU nature restoration law, which will assist in monitoring our development. Now, we need to focus on implementation and collaboration with participating nations to protect our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies is subsequent to the pioneering European-wide evaluation of hoverflies, another essential pollinating insect category. Released in twenty-twenty-two, it showed that 37% of all hoverfly varieties in European nations were facing extinction.
