The count of native bee types in European nations confronting dying out has more than doubled during the previous ten-year period, and the number of at-risk butterfly species has nearly doubled.
This dire scenario for crucial pollinators was disclosed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which determined that at least one hundred seventy-two bee types out of nearly two thousand were threatened with extinction in Europe.
The count of butterflies threatened with extinction in European nations has grown from over thirty-five to sixty-five since the previous assessment, performed a decade and a half ago. One species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
In addition to their beauty and cultural significance, pollinators like bees and butterflies are essential supports for our health, our food systems and our economies – sustaining the produce, vegetables and seeds that nourish us,” said the IUCN’s director general. “The newest European red list assessments reveal major obstacles, with threats increasing for butterfly types and vital native bee types.”
The reasons of the rapid recent declines are the ongoing harm or degradation of natural habitats caused by farming intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the application of fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of environments suitable for pollinators substantially boosts the danger of extinctions at local level.
Global warming is also revealed to be a major threat: Over half of all at-risk butterfly types in the European continent are threatened by the climate change crisis – roughly twofold the amount as a ten years ago.
Up to ninety percent of plants that flower in European nations depend on insect pollination, as stated by Dr Denis Michez. “Sadly, native bee populations are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If native bees vanish, many non-cultivated plants might be threatened too – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee types, which play a crucial role in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for fertilizing trees such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species found only in the continent and the sole species of this genus group in European nations, is now classified as critically at risk – the scientific classification nearest to dying out in natural habitats.
Butterflies that are solely present on mountain tops are especially at risk to global warming as they need to move uphill as their environments become warmer but ultimately exhaust available space. In Spain’s southern region, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (only found in Europe) at risk of extinction.
In the Mediterranean region, varieties such as the severely threatened Karpathos grayling butterfly are endangered by severe dry conditions and fires.
At the same time, in the Arctic Circle, global warming is causing the tree line to move north by dozens of meters each year, with scrub taking over bog and tundra. Higher temperatures also mean reindeer can no more cross the ice to feed on Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are facing extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The greatest living space for all these pollinating species is grassland rich in flowers and that is vanishing rapidly in Europe because of all these elements,” stated a lead coordinator for the butterfly assessment. “The good news is that so many citizens are aware now and there’s a lot more consciousness. Under the European Union nature restoration law, all member states have to reverse the decline in pollinating species by the year 2030, and they are going to have to begin taking action. There are property owners who are involved. It is hoped they can receive the motivations that will help them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of action for pollinating species which won’t reduce agricultural output – and could improve it – such as agricultural producers developing bloom-filled edges around their cultivated areas.
the EU’s environment commissioner, described the conservation status of native bees, butterflies and additional pollinators as “severe”.
“Urgent and collective action is needed to tackle this threat. In collaboration with participating nations, the European Commission has put in place an Europe-wide observation system for pollinating species based on the EU nature restoration regulation, which will help to track our development. Now, we need to prioritize execution and collaboration with member states to safeguard our pollinating insects,” she said.
The publication of the bee and butterfly assessments follows the first European-wide assessment of hoverflies, a further essential pollinating insect category. Issued in 2022, it revealed that thirty-seven percent of all hoverfly types in European nations were facing extinction.
