The number of non-managed bee species in European nations facing dying out has over doubled in the last ten years, whereas the number of at-risk butterfly species has close to doubled.
This dire scenario for essential pollinating insects was revealed by research studies for the IUCN red list, which found that at least over 170 bee varieties out of over 1900 were facing extinction in the European continent.
The count of butterfly species facing extinction in the European continent has risen from over thirty-five to 65 since the earlier research, conducted a decade and a half ago. One type, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
Apart from their visual charm and cultural significance, pollinating insects like bees along with butterflies are lifelines for our physical condition, our food chains and our economic systems – supporting the fruits, vegetables and seeds that nourish us,” said Grethel Aguilar. “The most recent European red list assessments reveal significant difficulties, with threats mounting for butterfly species and crucial non-managed bee varieties.”
The factors of the swift recent drops are the persistent destruction or damage of natural habitats caused by intensive agriculture and land abandonment, draining wetlands, excessive grazing by animals, and the utilization of chemical fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of pollinator-friendly habitat greatly increases the threat of local extinctions.
Global heating is also demonstrated to be a major threat: Over half of all endangered butterfly species in the European continent are endangered by the climate change crisis – roughly double the number as a ten years ago.
Nearly ninety percent of blooming plants in European nations rely on insect pollination, as per the lead coordinator of the wild bee assessment. “Unfortunately, native bee populations are in severe drop and cannot readily be substituted by managed bee colonies,” he said. “If non-managed bees vanish, many non-cultivated plants might be threatened too – of which flower-rich meadows and lovely orchid types are just a few examples.”
Fifteen species of bumblebee types, which perform a vital function in fertilizing crops such as peas, beans, peanuts and clover, and 14 species of cellophane bees, recognized for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the sole species of this biological genus in European nations, is now evaluated as critically at risk – the research category most akin to disappearance in the wild.
Butterflies that are exclusively located on high-altitude areas are highly susceptible to climate change as they need to move uphill as their environments become more heated but ultimately exhaust available space. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among above 40 percent of European endemics (only found in Europe) facing extinction.
In the Mediterranean, varieties such as the highly at-risk Karpathos grayling butterfly are imperilled by intense dry conditions and fires.
In the meantime, in the Arctic Circle, global warming is leading to the forest boundary to shift northward by dozens of meters each year, with bushes encroaching on bog and tundra. Hotter climates also mean Arctic deer can not anymore cross the ice to graze Arctic meadows and keep them open. 8 butterfly varieties are facing extinction in this region, including the fritillary of Freyja and the ringlet of the Arctic.
“The biggest habitat for all these pollinating species is grassland rich in flowers and that is disappearing very fast throughout the European continent because of all these reasons,” remarked a lead coordinator for the butterfly assessment. “The good news is that so many individuals are aware now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all member countries have to turn around the decline in pollinating species by 2030, and they are going to have to begin taking action. There are landowners who are interested. Let’s hope they can get the incentives that will assist them on their way.”
As stated by Martin Warren, there is “readily achievable actions” in terms of measures for pollinating insects which will not decrease agricultural output – and may enhance it – such as growers creating margins rich in flowers around their fields.
the EU’s environment commissioner, described the protection status of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Prompt and unified steps is necessary to tackle this threat. Together with participating nations, the Commission of the European Union has implemented an Europe-wide tracking system for pollinators based on the EU nature restoration regulation, which will assist in monitoring our advancement. Now, we need to prioritize implementation and partnership with member countries to preserve our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies follows the initial European-wide assessment of hoverflies, another crucial group of pollinators. Released in twenty-twenty-two, it disclosed that over one-third of all hoverfly species in Europe were at risk of extinction.
