The count of native bee types in European nations experiencing disappearance has increased twofold in the last ten years, while the number of endangered butterfly species has nearly doubled.
This pressing issue for essential pollinating species was unveiled by scientific assessments for the red list of threatened species, which determined that at least over 170 bee varieties out of nearly two thousand were threatened with extinction in Europe.
The total of butterflies facing extinction in the European continent 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 confirmed extinct.
Apart from their visual charm and cultural value, pollinating species like bees along with butterflies are lifelines for our physical condition, our food supplies and our economic systems – maintaining the fruits, veggies and seeds that nourish us,” stated Grethel Aguilar. “The newest European red list assessments reveal significant difficulties, with threats growing for butterfly types and essential non-managed bee species.”
The reasons of the swift recent drops are the persistent destruction or damage of natural habitats caused by intensive agriculture and land abandonment, draining wetlands, livestock overgrazing, and the utilization of pesticides and fertilisers including neonicotinoids. The division of pollinator-friendly habitat significantly raises the threat of local extinctions.
Climate change is also revealed to be a primary risk: Fifty-two percent of all at-risk butterfly species in European nations are threatened by the climate emergency – roughly twofold the amount as a ten years ago.
Nearly nine out of ten of plants that flower in European nations rely on animal pollination, as stated by the lead coordinator of the wild bee assessment. “Sadly, native bee colonies are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If native bees disappear, many non-cultivated plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a handful of illustrations.”
Fifteen types of bumblebee types, which play a crucial role in pollinating peas, beans, peanuts and clover, and 14 species of cellophane bee types, known for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the sole species of this biological genus in the European continent, is now assessed as critically endangered – the scientific classification closest to dying out in natural habitats.
Butterfly species that are only found on mountain peaks are especially at risk to climate change as they must ascend higher as their living spaces become warmer but eventually have no room left. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among above 40 percent of European endemics (solely present in Europe) facing extinction.
In the Mediterranean region, types such as the highly at-risk grayling of Karpathos are imperilled by severe dry conditions and fires.
At the same time, in the Arctic region, global heating is resulting in the tree line to move north by tens of metres each year, with bushes invading marsh and tundra. Higher temperatures also mean Arctic deer can no longer cross the ice sheets to feed on northern grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this zone, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The greatest habitat for all these pollinators is bloom-filled grassy areas and that is declining quickly throughout the European continent because of all these factors,” said Martin Warren. “The positive thing is that so many citizens are concerned now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member states have to halt the decline in pollinating species by the year 2030, and they are going to have to initiate measures. There are land holders who are interested. It is hoped they can get the incentives that will assist them on their way.”
According to Warren, there is “easy opportunities” in terms of action for pollinating insects which will not lower agricultural output – and could improve it – such as agricultural producers developing flower-rich margins around their cultivated areas.
the EU’s environment commissioner, portrayed the preservation condition of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Urgent and collective action is needed to confront this threat. Along with member states, the Commission of the European Union has established an European Union-wide monitoring system for pollinators based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to concentrate on application and partnership with participating nations to preserve our pollinating species,” she said.
The issuance of the bee and butterfly assessments follows the initial EU-wide study on hoverflies, a further crucial group of pollinators. Published in 2022, it showed that thirty-seven percent of all hoverfly types in the European continent were facing extinction.
