The count of wild bee varieties in the European continent experiencing extinction has increased twofold over the past decade, and the total of endangered butterfly species has close to doubled.
This pressing issue for crucial pollinators was disclosed by research studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least one hundred seventy-two bee species out of 1,928 were facing extinction in Europe.
The total of butterfly species facing extinction in European nations has increased from thirty-seven to 65 since the earlier research, conducted over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
“Beyond their visual charm and cultural significance, pollinating species like bees and butterflies are essential supports for our health, our food chains and our financial structures – supporting the fruits, veggies and seeds that sustain us,” commented Grethel Aguilar. “The latest European red list evaluations reveal significant difficulties, with risks growing for butterfly species and crucial non-managed bee types.”
The reasons of the quick recent decreases are the ongoing destruction or damage of habitats caused by intensive agriculture and abandoned land, wetland drainage, overgrazing by livestock, and the application of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat substantially boosts the threat of disappearances in specific areas.
Climate change is also demonstrated to be a primary risk: Fifty-two percent of all endangered butterfly species in the European continent are threatened by the climate change crisis – roughly twofold the amount as a decade ago.
Up to nine out of ten of plants that flower in Europe depend on insect pollination, according to the wild bee assessment’s lead coordinator. “Sadly, native bee groups are in sharp decrease and cannot be easily replaced by managed bee colonies,” he said. “If wild bees disappear, many wild plants might be at risk too – of which meadows rich in flowers and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebees, which perform a vital function in pollinating peas, beans, peanuts and clover, and 14 types of cellophane bees, famous for aiding tree pollination such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the only species of this genus in European nations, is now assessed as severely threatened – the research category most akin to disappearance in the wild.
Butterfly species that are exclusively located on mountain tops are especially at risk to climate change as they have to climb upward as their environments become hotter but in the end have no room left. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue are among above 40 percent of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean area, types such as the critically endangered Karpathos grayling butterfly are threatened by severe wildfires and drought.
Meanwhile, in the Arctic region, global warming is leading to the tree line to advance northwards by dozens of meters each year, with bushes encroaching on bog and tundra. Warmer conditions also mean reindeer can no more cross the ice sheets to browse Arctic grasslands and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The largest living space for all these pollinating species is grassland rich in flowers and that is vanishing rapidly across European nations because of all these reasons,” remarked Martin Warren. “The good news is that so many citizens are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member countries have to turn around the drop in pollinators by twenty-thirty, and they are going to have to begin taking action. There are property owners who are engaged. Let’s hope they can get the incentives that will help them on their way.”
As per Warren, there is “easy opportunities” in terms of measures for pollinating insects which will not lower food production – and may enhance it – such as agricultural producers creating margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, described the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Prompt and unified steps is necessary to tackle this risk. Along with participating nations, the European Commission has put in place an Europe-wide tracking system for pollinators based on the European Union nature restoration legislation, which will assist in monitoring our advancement. Now, we need to prioritize implementation and collaboration with member countries to preserve our pollinating species,” she said.
The publication of the assessments on bees and butterflies comes after the initial Europe-wide study on hoverflies, another essential pollinator group. Published in 2022, it disclosed that over one-third of all hoverfly species in the European continent were threatened with extinction.
