The number of native bee types in Europe experiencing extinction has more than doubled over the past decade, whereas the number of endangered butterfly has nearly doubled.
This pressing issue for vital pollinating insects was disclosed by research studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least 172 bee varieties out of 1,928 were at risk of extinction in the European continent.
The total of butterfly types facing extinction in Europe has increased from thirty-seven to 65 since the previous assessment, carried out a decade and a half ago. One species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their visual charm and cultural significance, pollinating species like bees and butterflies are essential supports for our health, our food systems and our economic systems – maintaining the fruits, vegetables and seeds that feed us,” stated Grethel Aguilar. “The most recent European red list evaluations reveal serious challenges, with risks mounting for butterflies and essential native bee species.”
The reasons of the rapid recent declines are the continuing damage or destruction of habitats caused by farming intensification and abandoned land, draining wetlands, livestock overgrazing, and the utilization of chemical fertilisers and pesticides including neonicotinoid chemicals. The division of pollinator-friendly habitat significantly raises the threat of extinctions at local level.
Global heating is also demonstrated to be a significant danger: Over half of all endangered butterfly types in European nations are threatened by the climate emergency – roughly twice as many as a decade ago.
Nearly ninety percent of blooming plants in the European continent depend on pollination by animals, as stated by the wild bee assessment’s lead coordinator. “Unfortunately, native bee populations are in drastic decline and cannot readily be substituted by domesticated hives,” he said. “If non-managed bees die out, many non-cultivated plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a handful of illustrations.”
Fifteen species of bumblebee species, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, recognized for pollinating trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species exclusive to the continent and the only species of this genus in European nations, is now evaluated as critically at risk – the scientific classification most akin to extinction in the wild.
Butterflies that are solely present on mountain tops are particularly vulnerable to global warming as they have to climb upward as their environments become warmer but eventually have no room left. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue are among above 40 percent of European endemics (exclusive to Europe) facing extinction.
In the Mediterranean, species such as the highly at-risk Karpathos grayling butterfly are threatened by intense dry conditions and fires.
Meanwhile, in the Far North, global heating is causing the timberline to move north by tens of metres each year, with scrub taking over marsh and tundra. Warmer conditions also mean reindeer can no more cross the ice sheets to browse Arctic grasslands and keep them open. Eight types of butterflies are at risk of extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The largest environment for all these pollinating insects is grassland rich in flowers and that is disappearing very fast in the European continent because of all these reasons,” stated a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many citizens are aware now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member states have to halt the drop in pollinating insects by 2030, and they are going to have to start doing something. There are land holders who are involved. We hope they can receive the motivations that will support them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of action for pollinators which won’t reduce agricultural output – and might boost it – such as agricultural producers creating margins rich in flowers around their fields.
the EU’s environment commissioner, characterized the preservation condition of native bees, butterflies and additional pollinators as “dire”.
“Urgent and collective action is needed to tackle this risk. Together with member countries, the EU Commission has implemented an EU-wide tracking system for pollinating insects based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to prioritize execution and partnership with member countries to preserve our pollinators,” she said.
The issuance of the bee and butterfly assessments comes after the pioneering Europe-wide assessment of hoverflies, a further crucial pollinator group. Published in twenty-twenty-two, it disclosed that thirty-seven percent of all hoverfly types in European nations were at risk of extinction.
