Worrying Rise in Endangered Non-Managed Bee Types Across Europe
The number of non-managed bee types in the European continent facing disappearance has over doubled during the previous ten-year period, and the count of at-risk butterfly has almost doubled.
This critical situation for essential pollinating species was disclosed by scientific studies for the IUCN red list, which established that at least 172 bee varieties out of over 1900 were facing extinction in the European continent.
The number of butterfly species facing extinction in European nations has increased from 37 to 65 since the earlier research, performed over a decade past. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
In addition to their visual charm and cultural importance, pollinating species like bees along with butterflies are crucial elements for our health, our food chains and our economies – supporting the fruits, vegetables and seeds that feed us,” said the IUCN’s director general. “The latest European red list assessments reveal serious challenges, with dangers growing for butterflies and vital native bee varieties.”
The causes of the quick recent decreases are the persistent harm or degradation of natural habitats caused by farming intensification and deserted farmland, draining wetlands, livestock overgrazing, and the utilization of chemical fertilisers and pesticides including neonicotinoids. The fragmentation of environments suitable for pollinators greatly increases the danger of local extinctions.
Climate change is also shown to be a significant danger: Fifty-two percent of all threatened butterflies in European nations are imperilled by the climate emergency – roughly double the number as a ten years ago.
Up to nine out of ten of plants that flower in Europe rely on pollination by animals, as stated by the wild bee assessment’s lead coordinator. “Regrettably, native bee populations are in sharp decrease and cannot readily be substituted by domesticated hives,” he said. “If wild bees die out, many wild plants might be at risk too – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
15 varieties of bumblebees, which play a crucial role in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for pollinating trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type found only in the continent and the sole species of this genus group in the European continent, is now evaluated as critically at risk – the scientific classification closest to disappearance in the wild.
Butterflies that are only found on mountain peaks are especially at risk to global warming as they have to climb upward as their environments become more heated but ultimately exhaust available space. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue 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 imperilled by extreme wildfires and drought.
At the same time, in the Far North, global warming is leading to the tree line to move north by many meters each year, with scrub invading wetlands and tundra. Higher temperatures also mean caribou can no more cross the ice sheets to feed on Arctic meadows and maintain them clear. Eight types of butterflies are at risk of extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.
“The biggest habitat for all these pollinators is flower-rich grassland and that is disappearing very fast in the European continent because of all these reasons,” remarked Martin Warren. “The positive thing is that so many individuals are concerned now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member countries have to reverse the drop in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are property owners who are involved. It is hoped they can get the motivations that will support them on their way.”
As stated by Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which will not lower food production – and could improve it – such as growers establishing flower-rich margins around their fields.
the EU’s environment commissioner, portrayed the protection status of native bees, butterflies and additional pollinators as “severe”.
“Urgent and collective action is required to tackle this danger. In collaboration with participating nations, the European Commission has put in place an European Union-wide tracking system for pollinating insects based on the EU nature restoration regulation, which will help to track our progress. Now, we need to focus on implementation and partnership with member countries to safeguard our pollinators,” she said.
The publication of the evaluations of bees along with butterflies comes after the initial Europe-wide study on hoverflies, another essential pollinator group. Released in 2022, it showed that over one-third of all hoverfly types in European nations were threatened with extinction.
