Worrying Surge in Endangered Native Bee Varieties Throughout European Nations

The total of non-managed bee species in Europe experiencing extinction has increased twofold during the previous ten-year period, whereas the number of endangered butterfly has almost doubled.

This critical situation for crucial pollinating insects was disclosed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which determined that at least one hundred seventy-two bee species out of over 1900 were at risk of extinction in Europe.

The number of butterfly types threatened with extinction in the European continent has grown from 37 to sixty-five since the previous assessment, performed a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.

Apart from their visual charm and cultural significance, pollinators like bees along with butterflies are essential supports for our physical condition, our food supplies and our economic systems – supporting the produce, vegetables and seeds that sustain us,” stated the IUCN director general. “The newest assessments of the European red list reveal serious challenges, with dangers growing for butterflies and essential non-managed bee varieties.”

The reasons of the rapid recent declines are the continuing damage or destruction of living environments caused by intensive agriculture and land abandonment, draining wetlands, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of habitat friendly to pollinators significantly raises the danger of extinctions at local level.

Climate change is also revealed to be a primary risk: Fifty-two percent of all threatened butterflies in European nations are imperilled by the climate change crisis – approximately double the number as a previous decade.

Up to nine out of ten of blooming plants in the European continent depend on pollination by animals, according to the wild bee assessment’s lead coordinator. “Regrettably, native bee colonies are in severe drop and cannot readily be substituted by managed colonies,” he said. “If native bees vanish, many non-cultivated plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”

15 varieties of bumblebee types, which have an essential part in fertilizing legumes like peas, beans, peanuts and clover, and 14 species of cellophane bees, known for fertilizing trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee exclusive to the continent and the single type of this genus group in European nations, is now classified as severely threatened – the research category nearest to disappearance in the wild.

Butterflies that are only found on mountain tops are highly susceptible to climate change as they have to climb upward as their living spaces become warmer but in the end run out of space. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue butterfly are among more than 40% of European endemics (solely present in Europe) at risk of extinction.

In the Mediterranean, species such as the severely threatened grayling of Karpathos are threatened by extreme dry conditions and fires.

In the meantime, in the Arctic region, global warming is causing the timberline to advance northwards by many meters each year, with underbrush taking over marsh and tundra. Hotter climates also mean caribou can no more cross the ice sheets to graze Arctic grasslands and maintain them clear. 8 butterfly varieties are threatened with extinction in this area, including Freyja’s fritillary and the Arctic ringlet butterfly.

“The biggest living space for all these pollinating species is bloom-filled grassy areas and that is vanishing rapidly throughout European nations because of all these reasons,” stated Martin Warren. “The good news is that so many citizens are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all participating nations have to halt the drop in pollinating species by 2030, and they are going to have to initiate measures. There are property owners who are engaged. It is hoped they can obtain the incentives that will support them on their way.”

As per the coordinator, there is “easy opportunities” in terms of measures for pollinating species which will not decrease crop yields – and may enhance it – such as farmers creating margins rich in flowers around their cultivated areas.

EU commissioner for environment, described the preservation condition of native bees, butterflies and additional pollinators as “dire”.

“Urgent and collective action is required to confront this threat. Together with member countries, the Commission of the European Union has established an European Union-wide monitoring system for pollinating insects based on the EU nature restoration law, which will help to track our advancement. Now, we need to prioritize implementation and collaboration with participating nations to safeguard our pollinators,” she said.

The issuance of the assessments on bees and butterflies is subsequent to the initial EU-wide assessment of hoverflies, a further essential group of pollinators. Issued in 2022, it revealed that 37% of all hoverfly types in European nations were threatened with extinction.
