Concerning Surge in At-Risk Non-Managed Bee Species In Europe

The total of non-managed bee species in Europe experiencing dying out has more than doubled during the previous ten-year period, while the number of endangered butterfly species has close to doubled.

This pressing issue for crucial pollinators was disclosed by scientific assessments for the red list of threatened species, which found that at least 172 bee varieties out of over 1900 were threatened with extinction in European nations.

The total of butterflies at risk of extinction in European nations has risen from over thirty-five to sixty-five since the last study, performed over a decade past. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.

“Beyond their visual charm and cultural importance, pollinators like bees and butterfly species are essential supports for our well-being, our food chains and our economies – maintaining the fruits, vegetables and seeds that sustain us,” commented Grethel Aguilar. “The most recent assessments of the European red list reveal serious challenges, with risks increasing for butterfly species and essential wild bee varieties.”

The causes of the rapid recent declines are the ongoing damage or destruction of habitats caused by agricultural intensification and abandoned land, draining wetlands, excessive grazing by animals, and the utilization of chemical fertilisers and pesticides including neonicotinoid pesticides. The division of pollinator-friendly habitat greatly increases the threat of local extinctions.

Global warming is also revealed to be a significant danger: Fifty-two percent of all threatened butterfly types in the European continent are threatened by the climate emergency – roughly twice as many as a previous decade.

Nearly 90% of flowering plants in Europe rely on animal pollination, as per the lead coordinator of the wild bee assessment. “Unfortunately, native bee populations are in sharp decrease and cannot be easily replaced by domesticated hives,” he said. “If native bees die out, many non-cultivated plants might be at risk too – of which meadows rich in flowers and attractive orchid varieties are just a handful of illustrations.”

Fifteen species of bumblebee species, which perform a vital function in fertilizing crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the sole species of this genus in Europe, is now classified as critically at risk – the scientific category most akin to disappearance in the wild.

Butterfly types that are solely present on mountain tops are especially at risk to climate change as they have to climb upward as their habitats become hotter but eventually run out of space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among above 40 percent of species endemic to Europe (solely present in Europe) threatened with extinction.

In the Mediterranean area, types such as the highly at-risk Karpathos grayling are threatened by extreme wildfires and drought.

Meanwhile, in the Far North, climate change is causing the forest boundary to shift northward by dozens of meters each year, with scrub encroaching on marsh and tundra. Warmer conditions also mean caribou can no longer cross the ice to feed on Arctic grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this region, including the fritillary of Freyja and the ringlet of the Arctic.

“The biggest environment for all these pollinators is flower-rich grassland and that is disappearing very fast throughout Europe because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many citizens are concerned now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member countries have to turn around the drop in pollinating species by the year 2030, and they are going to have to begin taking action. There are property owners who are involved. We hope they can obtain the encouragements that will help them on their way.”

As per the coordinator, there is “readily achievable actions” in terms of action for pollinating insects which won’t reduce agricultural output – and could improve it – such as farmers establishing bloom-filled edges around their fields.

the EU’s environment commissioner, characterized the preservation condition of wild bees, butterflies and other pollinators as “dire”.

“Prompt and unified steps is necessary to tackle this threat. In collaboration with participating nations, the Commission of the European Union has put in place an European Union-wide tracking system for pollinating insects based on the EU nature restoration regulation, which will aid in following our development. Now, we need to concentrate on application and partnership with member states to preserve our pollinators,” she said.

The issuance of the bee and butterfly assessments is subsequent to the first European-wide evaluation of hoverflies, a further crucial pollinator group. Published in twenty-twenty-two, it revealed that over one-third of all hoverfly varieties in the European continent were threatened with extinction.
