The number of wild bee types in Europe experiencing dying out has increased twofold over the past decade, while the count of at-risk butterfly species has nearly doubled.
This dire scenario for vital pollinating insects was unveiled by scientific studies for the red list of threatened species, which established that at least 172 bee types out of over 1900 were facing extinction in European nations.
The count of butterfly species threatened with extinction in Europe has increased from 37 to 65 since the last study, performed a decade and a half ago. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their visual charm and cultural value, pollinating species like bees and butterfly species are lifelines for our well-being, our food chains and our financial structures – maintaining the produce, vegetables and seeds that feed us,” said the IUCN’s director general. “The newest European red list evaluations reveal major obstacles, with risks mounting for butterfly species and essential non-managed bee varieties.”
The reasons of the swift recent drops are the persistent harm or degradation of habitats caused by farming intensification and abandoned land, wetland drainage, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoids. The fragmentation of pollinator-friendly habitat substantially boosts the danger of local extinctions.
Global warming is also shown to be a major threat: Over half of all threatened butterfly types in European nations are endangered by the climate change crisis – roughly double the number as a ten years ago.
As many as nine out of ten of plants that flower in the European continent depend on animal pollination, as per Dr Denis Michez. “Regrettably, wild bee colonies are in drastic decline and cannot readily be substituted by domesticated hives,” he said. “If non-managed bees die out, many native plants might be threatened too – of which meadows rich in flowers and beautiful orchid species are just a handful of illustrations.”
Fifteen species of bumblebee species, which play a crucial role in aiding the pollination of legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, known for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee unique to the continent and the single type of this genus group in Europe, is now assessed as critically at risk – the scientific category closest to dying out in natural habitats.
Butterfly species that are only found on mountain peaks are particularly vulnerable to climate change as they need to move uphill as their living spaces become warmer but in the end have no room left. In the southern part of Spain, the grayling of Nevada and the anomalous blue of Andalusia are among over forty percent of types unique to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean, varieties such as the severely threatened Karpathos grayling are imperilled by severe dry conditions and fires.
Meanwhile, in the Arctic Circle, global heating is resulting in the forest boundary to advance northwards by many meters each year, with underbrush taking over wetlands and tundra. Hotter climates also mean Arctic deer can no longer cross the ice sheets to browse northern grasslands and maintain them clear. Eight types of butterflies are at risk of extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The greatest living space for all these pollinating insects is bloom-filled grassy areas and that is declining quickly in European nations because of all these elements,” stated one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are aware now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all participating nations have to halt the decline in pollinating insects by twenty-thirty, and they are going to have to start doing something. There are land holders who are interested. It is hoped they can get the incentives that will help them on their way.”
As stated by Warren, there is “easy opportunities” in terms of measures for pollinating species which will not decrease agricultural output – and could improve it – such as agricultural producers developing bloom-filled edges around their farmland.
EU commissioner for environment, characterized the protection status of native bees, butterflies and additional pollinators as “critical”.
“Urgent and collective action is needed to tackle this threat. In collaboration with participating nations, the European Commission has put in place an EU-wide monitoring system for pollinating insects based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to focus on execution and collaboration with participating nations to protect our pollinators,” she said.
The publication of the assessments on bees and butterflies follows the pioneering European-wide evaluation of hoverflies, a further crucial group of pollinators. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly types in the European continent were threatened with extinction.
