Worrying Surge in At-Risk Non-Managed Bee Species Across European Nations

The number of wild bee varieties in European nations facing extinction has over doubled in the last ten years, and the number of threatened butterfly types has nearly doubled.

This critical situation for crucial pollinating species was revealed by scientific studies for the red list of threatened species, which established that at least 172 bee species out of 1,928 were threatened with extinction in European nations.

The count of butterfly species at risk of extinction in the European continent has risen from 37 to sixty-five since the last study, carried out over a decade past. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.

Apart from their visual charm and cultural value, pollinators like bees along with butterflies are lifelines for our health, our food chains and our economies – sustaining the produce, vegetables and seeds that nourish us,” said the IUCN director general. “The newest assessments of the European red list reveal major obstacles, with risks increasing for butterflies and crucial wild bee types.”

The causes of the quick recent decreases are the ongoing destruction or damage of habitats caused by farming intensification and land abandonment, draining wetlands, overgrazing by livestock, and the application of chemical fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of habitat friendly to pollinators substantially boosts the risk of extinctions at local level.

Global heating is also revealed to be a major threat: Fifty-two percent of all threatened butterfly species in the European continent are endangered by the climate crisis – roughly twice as many as a ten years ago.

Up to 90% of plants that flower in European nations depend on insect pollination, as per the lead coordinator of the wild bee assessment. “Unfortunately, native bee groups are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If native bees vanish, many native plants might be threatened 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 aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for pollinating trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type exclusive to the mainland and the only species of this genus in European nations, is now evaluated as critically at risk – the scientific classification nearest to disappearance in the wild.

Butterfly types that are solely present on high-altitude areas are especially at risk to climate change as they have to climb upward as their environments become hotter but eventually run out of space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue are among above 40 percent of species endemic to Europe (exclusive to Europe) facing extinction.

In the Mediterranean region, types such as the highly at-risk grayling of Karpathos are endangered by severe drought and wildfires.

At the same time, in the Arctic Circle, global warming is resulting in the tree line to advance northwards by many meters each year, with bushes invading bog and tundra. Hotter climates also mean Arctic deer can not anymore cross the ice to feed on northern grasslands and prevent them from overgrowing. 8 butterfly varieties are at risk of extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.

“The biggest environment for all these pollinating insects is bloom-filled grassy areas and that is disappearing very fast throughout Europe because of all these factors,” said one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many individuals are concerned now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all member states have to reverse the decrease in pollinating insects by twenty-thirty, and they are going to have to start doing something. There are property owners who are interested. It is hoped they can get the incentives that will support them on their way.”

As per the coordinator, there is “easy opportunities” in terms of action for pollinating species which will not decrease agricultural output – and might boost it – such as growers developing flower-rich margins around their cultivated areas.

the EU’s environment commissioner, described the protection status of native bees, butterflies and additional pollinators as “severe”.

“Immediate and joint measures is necessary to address this risk. Along with member countries, the EU Commission has implemented an European Union-wide observation system for pollinating insects based on the EU nature restoration law, which will aid in following our progress. Now, we need to prioritize application and partnership with member countries to preserve our pollinating species,” she said.

The release of the assessments on bees and butterflies is subsequent to the first EU-wide assessment of hoverflies, an additional vital group of pollinators. Published in twenty-twenty-two, it revealed that thirty-seven percent of all hoverfly types in Europe were at risk of extinction.
