The number of wild bee varieties in Europe facing dying out has over doubled in the last ten years, while the number of threatened butterfly types has close to doubled.
This pressing issue for essential pollinators was revealed by research studies for the red list of threatened species, which found that at least 172 bee species out of nearly two thousand were threatened with extinction in European nations.
The number of butterfly species facing extinction in the European continent has risen from 37 to sixty-five since the earlier research, carried out a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
“Beyond their aesthetic appeal and cultural significance, pollinators like bees along with butterflies are lifelines for our physical condition, our food systems and our economic systems – sustaining the fruits, veggies and seeds that sustain us,” stated the IUCN director general. “The latest European red list assessments reveal major obstacles, with risks increasing for butterfly types and vital non-managed bee species.”
The factors of the rapid recent declines are the persistent destruction or damage of natural habitats caused by farming intensification and land abandonment, draining wetlands, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat significantly raises the threat of extinctions at local level.
Climate change is also demonstrated to be a primary risk: 52% of all threatened butterflies in Europe are endangered by the climate change crisis – approximately twofold the amount as a decade ago.
Nearly ninety percent of blooming plants in Europe require insect pollination, as per the lead coordinator of the wild bee assessment. “Sadly, native bee populations are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees vanish, many native plants might be threatened too – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
15 varieties of bumblebee types, which perform a vital function in pollinating legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for fertilizing trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type found only in the European continent and the single type of this genus group in the European continent, is now assessed as critically endangered – the research category most akin to extinction in the wild.
Butterflies that are only found on mountain peaks are especially at risk to global heating as they need to move uphill as their environments become hotter but ultimately run out of space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue butterfly are among more than 40% of types unique to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean region, species such as the critically endangered Karpathos grayling butterfly are threatened by intense drought and wildfires.
Meanwhile, in the Far North, climate change is leading to the tree line to move north by tens of metres each year, with bushes encroaching on bog and tundra. Hotter climates also mean caribou can not anymore cross the ice to feed on Arctic meadows and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The largest environment for all these pollinators is bloom-filled grassy areas and that is disappearing very fast in European nations because of all these reasons,” said a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many citizens are aware now and there’s a lot more understanding. Under the EU nature restoration legislation, all participating nations have to reverse the drop in pollinators by the year 2030, and they are going to have to start doing something. There are land holders who are involved. 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 action for pollinating species which will not lower agricultural output – and may enhance it – such as growers creating margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, characterized the protection status of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Urgent and collective action is required to address this threat. Along with member countries, the Commission of the European Union has implemented an Europe-wide tracking system for pollinating insects based on the European Union nature restoration legislation, which will help to track our development. Now, we need to prioritize implementation and partnership with participating nations to preserve our pollinating insects,” she said.
The release of the bee and butterfly assessments follows the initial Europe-wide study on hoverflies, another crucial group of pollinators. Issued in twenty-twenty-two, it disclosed that over one-third of all hoverfly types in the European continent were threatened with extinction.
