The count of wild bee types in European nations facing dying out has more than doubled during the previous ten-year period, while the count of threatened butterfly species has close to doubled.
This dire scenario for essential pollinators was revealed by scientific studies for the IUCN red list, which determined that at least 172 bee species out of over 1900 were at risk of extinction in European nations.
The number of butterflies threatened with extinction in European nations has grown from over thirty-five to over sixty since the previous assessment, conducted a decade and a half ago. One species, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural importance, pollinating species like bees along with butterflies are lifelines for our physical condition, our food chains and our economies – maintaining the fruits, vegetables and seeds that sustain us,” said Grethel Aguilar. “The newest assessments of the European red list reveal serious challenges, with dangers increasing for butterfly species and crucial non-managed bee types.”
The causes of the swift recent drops are the continuing damage or destruction of natural habitats caused by intensive agriculture and abandoned land, draining wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoids. The division of habitat friendly to pollinators substantially boosts the threat of local extinctions.
Climate change is also demonstrated to be a primary risk: Over half of all threatened butterfly types in the European continent are endangered by the climate emergency – roughly twofold the amount as a decade ago.
Up to 90% of flowering plants in the European continent rely on animal pollination, as stated by the wild bee assessment’s lead coordinator. “Unfortunately, native bee groups are in severe drop and cannot readily be substituted by domesticated hives,” he said. “If native bees vanish, many native plants might be in danger as well – of which flower-rich meadows and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebee species, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for aiding tree pollination such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type unique to the European continent and the single type of this biological genus in European nations, is now evaluated as severely threatened – the scientific classification most akin to extinction in the wild.
Butterfly species that are exclusively located on high-altitude areas are particularly vulnerable to climate change as they have to climb upward as their habitats become hotter but eventually run out of space. In Spain’s southern region, the Nevada grayling and the anomalous blue of Andalusia are among over forty percent of species endemic to Europe (only found in Europe) threatened with extinction.
In the Mediterranean, species such as the severely threatened Karpathos grayling are imperilled by severe drought and wildfires.
Meanwhile, in the Far North, global heating is leading to the forest boundary to shift northward by many meters each year, with underbrush invading wetlands and tundra. Warmer conditions also mean reindeer can no longer cross the ice to feed on Arctic grasslands and prevent them from overgrowing. Eight types of butterflies are threatened with extinction in this region, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The biggest environment for all these pollinators is bloom-filled grassy areas and that is vanishing rapidly throughout the European continent because of all these elements,” stated one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many individuals are aware now and there’s a lot more consciousness. Under the European Union nature restoration law, all member states have to halt the decline in pollinating species by the year 2030, and they are going to have to initiate measures. There are property owners who are involved. It is hoped they can obtain the motivations that will help them on their way.”
As stated by Martin Warren, there is “low-hanging fruit” in terms of steps for pollinating insects which will not decrease food production – and may enhance it – such as growers establishing bloom-filled edges around their fields.
Jessika Roswall, portrayed the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Urgent and collective action is required to address this danger. In collaboration with participating nations, the EU Commission has established an European Union-wide observation system for pollinating species based on the EU nature restoration law, which will assist in monitoring our development. Now, we need to focus on implementation and partnership with member countries to protect our pollinators,” she said.
The issuance of the assessments on bees and butterflies comes after the first EU-wide evaluation of hoverflies, a further vital pollinating insect category. Released in 2022, it disclosed that 37% of all hoverfly varieties in the European continent were facing extinction.
