The count of wild bee types in European nations confronting dying out has over doubled in the last ten years, whereas the total of at-risk butterfly has close to doubled.
This pressing issue for vital pollinating insects was disclosed by research studies for the red list of threatened species, which determined that at least 172 bee types out of over 1900 were threatened with extinction in Europe.
The count of butterfly types facing extinction in Europe has grown from thirty-seven to 65 since the previous assessment, carried out a decade and a half ago. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
“Beyond their beauty and cultural importance, pollinating insects like bees and butterflies are lifelines for our health, our food chains and our economies – sustaining the produce, vegetables and seeds that feed us,” stated the IUCN director general. “The latest European red list assessments reveal major obstacles, with dangers increasing for butterfly species and essential wild bee types.”
The reasons of the quick recent decreases are the ongoing destruction or damage of living environments caused by intensive agriculture and abandoned land, draining of wetlands, livestock overgrazing, and the utilization of pesticides and fertilisers including neonicotinoids. The division of habitat friendly to pollinators significantly raises the danger of local extinctions.
Global warming is also demonstrated to be a significant danger: Over half of all threatened butterfly types in Europe are threatened by the climate change crisis – approximately twice as many as a previous decade.
Nearly nine out of ten of flowering plants in Europe rely on animal pollination, as per the lead coordinator of the wild bee assessment. “Sadly, wild bee colonies are in drastic decline and cannot readily be substituted by managed colonies,” he said. “If non-managed bees disappear, many non-cultivated plants might be in danger as well – of which flower-rich meadows and beautiful orchid species are just a handful of illustrations.”
15 varieties of bumblebee types, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee species, famous for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the European continent and the single type of this genus group in European nations, is now assessed as severely threatened – the scientific category closest to disappearance in the wild.
Butterfly types that are only found on mountain tops are particularly vulnerable to climate change as they need to move uphill as their habitats become more heated but ultimately exhaust available space. In southern Spain, the Nevada grayling and the anomalous blue of Andalusia are among over forty percent of species endemic to Europe (only found in Europe) facing extinction.
In the Mediterranean region, varieties such as the severely threatened Karpathos grayling are endangered by extreme dry conditions and fires.
In the meantime, in the Far North, global heating is resulting in the tree line to shift northward by tens of metres each year, with underbrush encroaching on bog and tundra. Higher temperatures also mean caribou can no longer cross the ice sheets to feed on Arctic meadows and keep them open. 8 butterfly varieties are at risk of extinction in this region, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The largest environment for all these pollinating species is flower-rich grassland and that is declining quickly in European nations because of all these reasons,” 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 awareness. Under the EU nature restoration legislation, all member states have to reverse the drop in pollinating species by twenty-thirty, and they are going to have to start doing something. There are property owners who are interested. Let’s hope they can receive the encouragements that will support them on their way.”
As stated by the coordinator, there is “readily achievable actions” in terms of action for pollinating insects which won’t reduce crop yields – and could improve it – such as farmers developing margins rich in flowers around their farmland.
the EU’s environment commissioner, portrayed the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Prompt and unified steps is necessary to address this danger. Along with member countries, the Commission of the European Union has established an European Union-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will help to track our advancement. Now, we need to focus on implementation and collaboration with participating nations to safeguard our pollinating species,” she said.
The issuance of the assessments on bees and butterflies comes after the pioneering Europe-wide assessment of hoverflies, a further crucial group of pollinators. Issued in 2022, it revealed that 37% of all hoverfly types in the European continent were at risk of extinction.
