The count of native bee types in European nations confronting dying out has increased twofold in the last ten years, while the count of at-risk butterfly species has nearly doubled.
This dire scenario for vital pollinating species was revealed by scientific assessments for the red list of threatened species, which established that at least 172 bee types out of nearly two thousand were facing extinction in Europe.
The number of butterfly species facing extinction in Europe has grown from over thirty-five to over sixty since the earlier research, conducted 14 years ago. A single species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
In addition to their aesthetic appeal and cultural importance, pollinators like bees along with butterflies are lifelines for our health, our food systems and our financial structures – sustaining the fruits, vegetables and seeds that sustain us,” commented Grethel Aguilar. “The most recent European red list evaluations reveal serious challenges, with risks growing for butterfly species and crucial native bee types.”
The causes of the rapid recent declines are the persistent destruction or damage of living environments caused by intensive agriculture and land abandonment, draining of wetlands, excessive grazing by animals, and the application of chemical fertilisers and pesticides including neonicotinoid chemicals. The division of environments suitable for pollinators substantially boosts the danger of local extinctions.
Global warming is also demonstrated to be a significant danger: Fifty-two percent of all at-risk butterfly types in Europe are endangered by the climate change crisis – approximately twice as many as a previous decade.
As many as ninety percent of plants that flower in European nations depend on insect pollination, as stated by Dr Denis Michez. “Regrettably, wild bee colonies are in sharp decrease and cannot be easily replaced by managed bee colonies,” he said. “If wild bees disappear, many non-cultivated plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a few examples.”
Fifteen types of bumblebee species, which play a crucial role in pollinating legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee species, famous for aiding tree pollination such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species unique to the mainland and the single type of this biological genus in the European continent, is now evaluated as critically endangered – the scientific category nearest to extinction in the wild.
Butterfly types that are only found on high-altitude areas are highly susceptible to global heating as they need to move uphill as their living spaces become warmer but ultimately exhaust available space. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of types unique to Europe (only found in Europe) facing extinction.
In the Mediterranean region, species such as the highly at-risk grayling of Karpathos are threatened by severe dry conditions and fires.
Meanwhile, in the Arctic region, global warming is resulting in the forest boundary to shift northward by dozens of meters each year, with bushes encroaching on bog and tundra. Higher temperatures also mean reindeer can not anymore cross the frozen water to browse northern grasslands and keep them open. 8 butterfly varieties are at risk of extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The largest living space for all these pollinating species is bloom-filled grassy areas and that is disappearing very fast across Europe because of all these factors,” stated one of the lead coordinators of the butterflies assessment. “The positive thing is that so many individuals care now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to halt the decrease in pollinating insects by the year 2030, and they are going to have to start doing something. There are land holders who are engaged. It is hoped they can obtain the motivations that will assist them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of action for pollinating insects which won’t reduce crop yields – and might boost it – such as farmers creating margins rich in flowers around their farmland.
Jessika Roswall, portrayed the preservation condition of native bees, butterflies and additional pollinators as “dire”.
“Immediate and joint measures is needed to confront this threat. Together with participating nations, the EU Commission has established an EU-wide monitoring system for pollinating insects based on the EU nature restoration regulation, which will help to track our progress. Now, we need to focus on implementation and cooperation with member countries to protect our pollinators,” she said.
The publication of the bee and butterfly assessments is subsequent to the initial European-wide study on hoverflies, a further vital pollinator group. Released in twenty-twenty-two, it showed that 37% of all hoverfly species in Europe were at risk of extinction.
