The total of native bee varieties in the European continent confronting dying out has more than doubled during the previous ten-year period, whereas the count of threatened butterfly has close to doubled.
This critical situation for crucial pollinating species was revealed by scientific assessments for the IUCN red list, which found that at least one hundred seventy-two bee types out of 1,928 were at risk of extinction in European nations.
The total of butterfly types threatened with extinction in European nations has grown from over thirty-five to over sixty since the previous assessment, performed a decade and a half ago. A single species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
Apart from their visual charm and cultural value, pollinators like bees and butterflies are essential supports for our health, our food supplies and our economies – supporting the fruits, veggies and seeds that sustain us,” said the IUCN’s director general. “The newest European red list assessments reveal major obstacles, with dangers mounting for butterfly types and essential native bee types.”
The reasons of the swift recent drops are the continuing harm or degradation of habitats caused by agricultural intensification and abandoned land, wetland drainage, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoids. The breaking up of habitat friendly to pollinators substantially boosts the risk of local extinctions.
Climate change is also shown to be a primary risk: 52% of all at-risk butterflies in Europe are endangered by the climate crisis – roughly twofold the amount as a ten years ago.
Nearly 90% of blooming plants in European nations rely on insect pollination, according to the wild bee assessment’s lead coordinator. “Sadly, native bee colonies are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees vanish, many non-cultivated plants might be in danger as well – of which flower-rich meadows and lovely orchid types are just a handful of illustrations.”
Fifteen types of bumblebee types, which play a crucial role in fertilizing crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for aiding tree pollination such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the continent and the sole species of this genus group in the European continent, is now evaluated as critically endangered – the scientific classification most akin to extinction in the wild.
Butterfly species that are only found on high-altitude areas are particularly vulnerable to global warming as they need to move uphill as their living spaces become warmer but in the end exhaust available space. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean, varieties such as the highly at-risk Karpathos grayling butterfly are threatened by extreme dry conditions and fires.
Meanwhile, in the Arctic region, global heating is causing the timberline to shift northward by dozens of meters each year, with underbrush taking over wetlands and tundra. Higher temperatures also mean reindeer can not anymore cross the ice sheets to feed on Arctic grasslands and maintain them clear. 8 butterfly varieties are facing extinction in this area, 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 vanishing rapidly across European nations because of all these reasons,” stated one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many citizens care now and there’s a lot more understanding. Under the EU nature restoration legislation, all member states have to reverse the drop in pollinators by twenty-thirty, and they are going to have to begin taking action. There are landowners who are involved. We hope they can get the incentives that will support them on their way.”
As stated by the coordinator, there is “readily achievable actions” in terms of measures for pollinators which will not lower agricultural output – and could improve it – such as farmers establishing bloom-filled edges around their farmland.
Jessika Roswall, characterized the protection status of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Prompt and unified steps is needed to tackle this risk. In collaboration with member countries, the Commission of the European Union has established an Europe-wide observation system for pollinating insects based on the European Union nature restoration legislation, which will aid in following our advancement. Now, we need to focus on implementation and partnership with member countries to safeguard our pollinating species,” she said.
The publication of the assessments on bees and butterflies follows the initial Europe-wide assessment of hoverflies, another vital group of pollinators. Issued in twenty-twenty-two, it revealed that thirty-seven percent of all hoverfly varieties in the European continent were at risk of extinction.
