Worrying Rise in Endangered Wild Bee Varieties Throughout the European Continent
The number of wild bee types in European nations experiencing dying out has over doubled during the previous ten-year period, and the count of at-risk butterfly types has close to doubled.
This critical situation for essential pollinators was unveiled by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least one hundred seventy-two bee species out of nearly two thousand were at risk of extinction in the European continent.
The count of butterfly species threatened with extinction in Europe has increased from 37 to sixty-five since the earlier research, performed a decade and a half ago. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
In addition to their visual charm and cultural importance, pollinating species like bees along with butterflies are crucial elements for our well-being, our food supplies and our economies – sustaining the produce, vegetables and seeds that feed us,” commented the IUCN’s director general. “The most recent European red list assessments reveal significant difficulties, with risks mounting for butterflies and essential non-managed bee varieties.”
The causes of the swift recent drops are the ongoing destruction or damage of habitats caused by agricultural intensification and land abandonment, draining wetlands, livestock overgrazing, and the application of chemical fertilisers and pesticides including neonicotinoid chemicals. The fragmentation of pollinator-friendly habitat significantly raises the risk of disappearances in specific areas.
Global heating is also demonstrated to be a major threat: 52% of all threatened butterfly types in Europe are threatened by the climate change crisis – roughly twofold the amount as a previous decade.
Nearly nine out of ten of plants that flower in Europe require pollination by animals, as per the wild bee assessment’s lead coordinator. “Unfortunately, non-managed bee populations are in severe drop and cannot readily be substituted by domesticated hives,” he said. “If non-managed bees vanish, many non-cultivated plants might be at risk too – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
Fifteen species of bumblebee types, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, famous for aiding tree pollination 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 genus in Europe, is now evaluated as critically at risk – the scientific category most akin to disappearance in the wild.
Butterfly species that are exclusively located on mountain tops are particularly vulnerable to global warming as they have to climb upward as their habitats become hotter but ultimately exhaust available space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean area, varieties such as the severely threatened grayling of Karpathos are endangered by intense dry conditions and fires.
Meanwhile, in the Far North, global heating is leading to the tree line to shift northward by many meters each year, with scrub taking over marsh and tundra. Warmer conditions also mean reindeer can no more cross the frozen water to graze northern grasslands and keep them open. Eight types of butterflies are threatened with extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The greatest environment for all these pollinating species is flower-rich grassland and that is disappearing very fast in the European continent because of all these reasons,” stated Martin Warren. “The positive thing is that so many individuals are concerned now and there’s a lot more understanding. Under the EU nature restoration legislation, all member states have to halt the decrease in pollinating insects by the year 2030, and they are going to have to begin taking action. There are landowners who are interested. Let’s hope they can get the incentives that will support them on their way.”
According to the coordinator, there is “low-hanging fruit” in terms of action for pollinators which will not decrease agricultural output – and may enhance it – such as farmers developing margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, portrayed the protection status of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is necessary to tackle this threat. In collaboration with participating nations, the EU Commission has established an European Union-wide monitoring system for pollinating insects based on the European Union nature restoration legislation, which will assist in monitoring our development. Now, we need to focus on execution and partnership with member states to safeguard our pollinators,” she said.
The release of the assessments on bees and butterflies comes after the pioneering EU-wide assessment of hoverflies, a further vital group of pollinators. Issued in 2022, it revealed that over one-third of all hoverfly varieties in Europe were at risk of extinction.
