The number of wild bee species in European nations experiencing extinction has over doubled in the last ten years, whereas the total of threatened butterfly has almost doubled.
This pressing issue for essential pollinators was disclosed by scientific assessments for the IUCN red list, which found that at least over 170 bee varieties out of nearly two thousand were at risk of extinction in the European continent.
The total of butterfly types at risk of extinction in the European continent has grown from 37 to sixty-five since the last study, carried out over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
In addition to their visual charm and cultural value, pollinating insects like bees along with butterflies are essential supports for our physical condition, our food systems and our financial structures – sustaining the produce, vegetables and seeds that sustain us,” said the IUCN’s director general. “The latest assessments of the European red list reveal major obstacles, with threats increasing for butterflies and crucial native bee varieties.”
The factors of the swift recent drops are the persistent harm or degradation of natural habitats caused by agricultural intensification and abandoned land, draining wetlands, excessive grazing by animals, and the use of pesticides and fertilisers including neonicotinoid chemicals. The breaking up of environments suitable for pollinators greatly increases the danger of local extinctions.
Climate change is also revealed to be a major threat: Fifty-two percent of all threatened butterflies in the European continent are threatened by the climate emergency – about twofold the amount as a previous decade.
As many as 90% of plants that flower in Europe require insect pollination, according to Dr Denis Michez. “Unfortunately, non-managed bee colonies are in severe drop and are not easily replaceable by managed colonies,” he said. “If native bees vanish, many wild plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a few examples.”
Fifteen types of bumblebee species, which play a crucial role in pollinating legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type unique to the continent and the single type of this biological genus in the European continent, is now assessed as severely threatened – the scientific category most akin to dying out in natural habitats.
Butterfly types that are solely present on high-altitude areas are especially at risk to global warming as they must ascend higher as their habitats become warmer but eventually have no room left. In the southern part of Spain, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of European endemics (exclusive to Europe) facing extinction.
In the Mediterranean region, types such as the critically endangered Karpathos grayling are endangered by severe dry conditions and fires.
Meanwhile, in the Arctic region, global heating is leading to the tree line to shift northward by dozens of meters each year, with scrub invading bog and tundra. Hotter climates also mean caribou can no more cross the ice sheets to graze northern grasslands and keep them open. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The largest habitat for all these pollinators is bloom-filled grassy areas and that is declining quickly in European nations because of all these elements,” stated Martin Warren. “The good news is that so many individuals are concerned now and there’s a lot more consciousness. Under the European Union nature restoration law, all participating nations have to reverse the decline in pollinating insects by twenty-thirty, and they are going to have to start doing something. There are property owners who are engaged. It is hoped they can receive the encouragements that will help them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of steps for pollinating species which won’t reduce food production – and could improve it – such as growers establishing flower-rich margins around their farmland.
Jessika Roswall, portrayed the protection status of wild bees, butterflies and other pollinators as “critical”.
“Urgent and collective action is needed to confront this threat. Together with member countries, the EU Commission has established an European Union-wide monitoring system for pollinators based on the EU nature restoration regulation, which will help to track our development. Now, we need to focus on implementation and partnership with participating nations to preserve our pollinating species,” she said.
The release of the bee and butterfly assessments follows the initial Europe-wide evaluation of hoverflies, another essential pollinator group. Published in twenty-twenty-two, it showed that over one-third of all hoverfly varieties in Europe were threatened with extinction.
