The number of native bee species in European nations confronting dying out has increased twofold in the last ten years, whereas the total of endangered butterfly species has almost doubled.
This dire scenario for crucial pollinators was revealed by scientific assessments for the IUCN red list, which established that at least over 170 bee types out of 1,928 were facing extinction in the European continent.
The total of butterfly species facing extinction in European nations has increased from thirty-seven to sixty-five since the earlier research, performed 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
Apart from their beauty and cultural importance, pollinating insects like bees along with butterflies are essential supports for our well-being, our food chains and our economies – maintaining the produce, vegetables and seeds that feed us,” commented Grethel Aguilar. “The latest European red list assessments reveal serious challenges, with dangers increasing for butterfly types and vital wild bee species.”
The reasons of the quick recent decreases are the ongoing harm or degradation of living environments caused by intensive agriculture and abandoned land, draining wetlands, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of environments suitable for pollinators substantially boosts the danger of disappearances in specific areas.
Global warming is also shown to be a major threat: Over half of all at-risk butterfly types in Europe are imperilled by the climate change crisis – roughly twice as many as a decade ago.
As many as 90% of blooming plants in Europe rely on pollination by animals, as stated by the lead coordinator of the wild bee assessment. “Sadly, native bee populations are in severe drop and cannot be easily replaced by managed colonies,” he said. “If non-managed bees die out, many wild plants might be at risk too – of which flower-rich meadows and beautiful orchid species are just a few examples.”
Fifteen species of bumblebee species, which have an essential part in fertilizing peas, beans, peanuts and clover, and 14 species of cellophane bees, known for pollinating trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the only species of this biological genus in the European continent, is now assessed as critically at risk – the research category closest to disappearance in the wild.
Butterflies that are exclusively located on high-altitude areas are particularly vulnerable to global heating as they must ascend higher as their environments become warmer but in the end exhaust available space. In southern Spain, the Nevada grayling and the Andalusian anomalous blue are among above 40 percent of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean, types such as the highly at-risk grayling of Karpathos are threatened by extreme drought and wildfires.
Meanwhile, in the Arctic Circle, climate change is causing the timberline to advance northwards by tens of metres each year, with underbrush taking over marsh and tundra. Warmer conditions also mean Arctic deer can not anymore cross the ice to graze Arctic grasslands and keep them open. 8 butterfly varieties are threatened with extinction in this area, including the fritillary of Freyja and the ringlet of the Arctic.
“The biggest environment for all these pollinating species is bloom-filled grassy areas and that is declining quickly in the European continent because of all these factors,” stated one of the lead coordinators of the butterflies assessment. “The encouraging aspect 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 reverse the decrease in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are land holders who are involved. Let’s hope they can obtain the motivations that will support them on their way.”
As stated by the coordinator, there is “easy opportunities” in terms of action for pollinating species which will not decrease agricultural output – and could improve it – such as agricultural producers developing bloom-filled edges around their farmland.
EU commissioner for environment, described the preservation condition of wild bees, butterflies and other pollinators as “dire”.
“Immediate and joint measures is needed to address this danger. Along with member countries, the EU Commission has put in place an EU-wide monitoring system for pollinators based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to focus on implementation and collaboration with participating nations to protect our pollinators,” she said.
The release of the assessments on bees and butterflies is subsequent to the initial Europe-wide assessment of hoverflies, a further essential group of pollinators. Issued in twenty-twenty-two, it disclosed that thirty-seven percent of all hoverfly species in the European continent were threatened with extinction.
