The number of non-managed bee species in the European continent confronting disappearance has more than doubled during the previous ten-year period, and the count of threatened butterfly has nearly doubled.
This pressing issue for crucial pollinating insects was disclosed by research studies for the red list of threatened species, which determined that at least one hundred seventy-two bee types out of 1,928 were threatened with extinction in Europe.
The count of butterflies threatened with extinction in European nations has grown from 37 to sixty-five since the earlier research, carried out over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
In addition to their visual charm and cultural significance, pollinators like bees and butterfly species are lifelines for our well-being, our food chains and our economies – sustaining the fruits, veggies and seeds that nourish us,” said the IUCN’s director general. “The latest European red list assessments reveal serious challenges, with dangers mounting for butterfly types and essential non-managed bee species.”
The causes of the rapid recent declines are the ongoing harm or degradation of natural habitats caused by farming intensification and abandoned land, draining wetlands, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoid chemicals. The fragmentation of pollinator-friendly habitat substantially boosts the threat of local extinctions.
Climate change is also demonstrated to be a major threat: 52% of all endangered butterfly types in the European continent are imperilled by the climate emergency – roughly twice as many as a ten years ago.
As many as nine out of ten of plants that flower in European nations depend on animal pollination, according to Dr Denis Michez. “Regrettably, non-managed bee groups are in severe drop and cannot readily be substituted by managed bee colonies,” he said. “If native bees die out, many non-cultivated plants might be in danger as well – of which flower-rich meadows and lovely orchid types are just a handful of illustrations.”
Fifteen species of bumblebees, which have an essential part in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee species, recognized for aiding tree pollination such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the single type of this genus in the European continent, is now evaluated as critically endangered – the scientific classification most akin to dying out in natural habitats.
Butterflies that are exclusively located on mountain tops are highly susceptible to global heating as they have to climb upward as their habitats become more heated but eventually exhaust available space. In the southern part of Spain, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean area, types such as the critically endangered grayling of Karpathos are endangered by intense wildfires and drought.
In the meantime, in the Arctic region, climate change is leading to the timberline to move north by tens of metres each year, with bushes invading bog and tundra. Hotter climates also mean reindeer can not anymore cross the ice sheets to browse northern grasslands and prevent them from overgrowing. Eight types of butterflies are facing extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The largest living space for all these pollinating species is flower-rich grassland and that is vanishing rapidly across European nations because of all these elements,” remarked a lead coordinator for the butterfly assessment. “The encouraging aspect 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 drop in pollinators by the year 2030, and they are going to have to start doing something. There are landowners who are interested. Let’s hope they can get the motivations that will help them on their way.”
As stated by the coordinator, there is “readily achievable actions” in terms of measures for pollinating species which will not lower food production – and could improve it – such as agricultural producers developing bloom-filled edges around their fields.
Jessika Roswall, characterized the preservation condition of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Immediate and joint measures is needed to confront this risk. Along with participating nations, the European Commission has implemented an Europe-wide tracking system for pollinating insects based on the EU nature restoration law, which will aid in following our advancement. Now, we need to focus on execution and cooperation with participating nations to safeguard our pollinators,” she said.
The issuance of the assessments on bees and butterflies follows the first EU-wide evaluation of hoverflies, another crucial pollinating insect category. Published in 2022, it showed that 37% of all hoverfly species in European nations were threatened with extinction.
