Alarming Rise in Endangered Non-Managed Bee Varieties Across European Nations

The total of non-managed bee varieties in Europe confronting dying out has increased twofold over the past decade, while the count of at-risk butterfly has close to doubled.

This critical situation for crucial pollinating species was disclosed by scientific assessments for the IUCN red list, which found that at least over 170 bee varieties out of over 1900 were facing extinction in the European continent.

The number of butterfly species at risk of extinction in the European continent has grown from 37 to sixty-five since the earlier research, carried out a decade and a half ago. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.

“Beyond their beauty and cultural significance, pollinating insects like bees along with butterflies are lifelines for our well-being, our food chains and our economic systems – sustaining the fruits, vegetables and seeds that sustain us,” stated the IUCN’s director general. “The latest European red list evaluations reveal significant difficulties, with threats growing for butterfly types and crucial native bee varieties.”

The reasons of the rapid recent declines are the persistent harm or degradation of habitats caused by agricultural intensification and deserted farmland, wetland drainage, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoid pesticides. The breaking up of pollinator-friendly habitat substantially boosts the threat of disappearances in specific areas.

Global warming is also revealed to be a significant danger: Over half of all threatened butterfly species in the European continent are endangered by the climate crisis – roughly double the number as a previous decade.

As many as ninety percent of flowering plants in European nations rely on animal pollination, as per the lead coordinator of the wild bee assessment. “Sadly, native bee colonies are in sharp decrease and are not easily replaceable by domesticated hives,” he said. “If non-managed bees vanish, many native plants might be in danger as well – of which bloom-filled grasslands and lovely orchid types are just a few examples.”

Fifteen species of bumblebees, which have an essential part in pollinating peas, beans, peanuts and clover, and 14 species of cellophane bees, recognized for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the European continent and the only species of this genus group in the European continent, is now evaluated as critically endangered – the research category most akin to disappearance in the wild.

Butterfly species that are only found on high-altitude areas are especially at risk to global warming as they have to climb upward as their living spaces become more heated but eventually have no room left. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (exclusive to Europe) at risk of extinction.

In the Mediterranean area, species such as the severely threatened Karpathos grayling are imperilled by severe drought and wildfires.

In the meantime, in the Far North, global warming is resulting in the forest boundary to advance northwards by dozens of meters each year, with bushes invading wetlands and tundra. Hotter climates also mean Arctic deer can no longer cross the ice sheets to feed on northern grasslands 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 largest living space for all these pollinators is flower-rich grassland and that is vanishing rapidly throughout Europe because of all these factors,” stated Martin Warren. “The good news is that so many people care now and there’s a lot more awareness. Under the European Union nature restoration law, all member countries have to halt the drop in pollinating insects by twenty-thirty, and they are going to have to initiate measures. There are land holders who are interested. It is hoped they can obtain the motivations that will help them on their way.”

As per the coordinator, there is “low-hanging fruit” in terms of measures for pollinating species which will not lower crop yields – and might boost it – such as agricultural producers developing bloom-filled edges around their farmland.

Jessika Roswall, characterized the conservation status of wild bees, butterflies and other pollinators as “critical”.

“Immediate and joint measures is required to address this threat. In collaboration with member countries, the Commission of the European Union has established an Europe-wide tracking system for pollinating species based on the EU nature restoration regulation, which will help to track our progress. Now, we need to prioritize implementation and partnership with member countries to preserve our pollinating species,” she said.

The release of the evaluations of bees along with butterflies is subsequent to the initial EU-wide evaluation of hoverflies, a further vital pollinator group. Released in twenty-twenty-two, it revealed that 37% of all hoverfly types in European nations were at risk of extinction.
