Concerning Rise in Threatened Non-Managed Bee Species In European Nations

The number of wild bee types in Europe facing disappearance has over doubled over the past decade, while the total of at-risk butterfly types has close to doubled.

This dire scenario for essential pollinators was disclosed by research studies for the IUCN red list, which determined that at least one hundred seventy-two bee types out of over 1900 were facing extinction in the European continent.

The number of butterflies facing extinction in Europe has increased from 37 to over sixty since the last study, conducted 14 years ago. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.

In addition to their visual charm and cultural significance, pollinators like bees and butterfly species are crucial elements for our well-being, our food supplies and our financial structures – supporting the fruits, veggies and seeds that feed us,” stated the IUCN director general. “The latest European red list assessments reveal significant difficulties, with dangers increasing for butterfly species and crucial native bee varieties.”

The causes of the swift recent drops are the persistent destruction or damage of living environments caused by agricultural intensification and land abandonment, draining wetlands, excessive grazing by animals, and the use of chemical fertilisers and pesticides including neonicotinoids. The division of environments suitable for pollinators greatly increases the threat of local extinctions.

Global heating is also revealed to be a significant danger: Over half of all at-risk butterfly types in Europe are imperilled by the climate change crisis – about twofold the amount as a decade ago.

Up to 90% of plants that flower in European nations require animal pollination, as stated by the wild bee assessment’s lead coordinator. “Regrettably, wild bee colonies are in severe drop and cannot readily be substituted by managed bee colonies,” he said. “If wild bees vanish, many native plants might be threatened too – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”

Fifteen species of bumblebee species, which have an essential part in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for fertilizing trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type unique to the mainland and the single type of this genus group in Europe, is now classified as critically at risk – the research category closest to disappearance in the wild.

Butterflies that are only found on mountain peaks are highly susceptible to global warming as they have to climb upward as their living spaces become hotter but eventually have no room left. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue are among more than 40% of types unique to Europe (solely present in Europe) at risk of extinction.

In the Mediterranean region, varieties such as the severely threatened grayling of Karpathos are endangered by intense drought and wildfires.

In the meantime, in the Arctic Circle, climate change is leading to the timberline to shift northward by many meters each year, with bushes invading marsh and tundra. Warmer conditions also mean caribou can no longer cross the frozen water to graze northern grasslands and prevent them from overgrowing. 8 butterfly varieties are at risk of extinction in this zone, including Freyja’s fritillary and the Arctic ringlet butterfly.

“The largest environment for all these pollinating insects is grassland rich in flowers and that is vanishing rapidly throughout the European continent because of all these reasons,” remarked Martin Warren. “The encouraging aspect is that so many citizens are concerned now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member states have to halt the decline in pollinating insects by 2030, and they are going to have to initiate measures. There are land holders who are engaged. We hope they can receive the incentives that will assist them on their way.”

As per Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which will not lower crop yields – and could improve it – such as farmers establishing bloom-filled edges around their fields.

EU commissioner for environment, portrayed the protection status of non-managed bees, butterfly species and other pollinating insects as “dire”.

“Immediate and joint measures is required to address this threat. In collaboration with member states, the European Commission has put in place an Europe-wide observation system for pollinators based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to concentrate on implementation and cooperation with member countries to safeguard our pollinating insects,” she said.

The publication of the assessments on bees and butterflies comes after the initial Europe-wide evaluation of hoverflies, a further crucial pollinator group. Released in twenty-twenty-two, it showed that over one-third of all hoverfly types in the European continent were facing extinction.
