The number of non-managed bee species in Europe experiencing disappearance has increased twofold over the past decade, while the number of endangered butterfly has nearly doubled.
This pressing issue for vital pollinating insects was revealed by scientific assessments for the IUCN red list, which found that at least one hundred seventy-two bee species out of 1,928 were at risk of extinction in European nations.
The number of butterflies at risk of extinction in Europe has risen from 37 to sixty-five since the earlier research, conducted over a decade past. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
In addition to their aesthetic appeal and cultural significance, pollinating insects like bees and butterflies are crucial elements for our well-being, our food systems and our financial structures – supporting the fruits, veggies and seeds that feed us,” stated the IUCN’s director general. “The most recent European red list assessments reveal serious challenges, with risks growing for butterfly types and vital non-managed bee types.”
The factors of the swift recent drops are the ongoing destruction or damage of living environments caused by farming intensification and abandoned land, wetland drainage, excessive grazing by animals, and the application of fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of environments suitable for pollinators substantially boosts the threat of extinctions at local level.
Climate change is also demonstrated to be a major threat: Over half of all at-risk butterfly types in Europe are endangered by the climate emergency – about twofold the amount as a decade ago.
Nearly nine out of ten of blooming plants in European nations require animal pollination, as per Dr Denis Michez. “Regrettably, non-managed bee populations are in drastic decline and cannot readily be substituted by managed colonies,” he said. “If wild bees die out, many wild plants might be in danger as well – of which flower-rich meadows and beautiful orchid species are just a few examples.”
Fifteen types of bumblebee types, which play a crucial role in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee types, recognized for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the sole species of this genus in Europe, is now classified as critically endangered – the scientific category closest to dying out in natural habitats.
Butterfly types that are exclusively located on mountain tops are highly susceptible to global warming as they must ascend higher as their habitats become hotter but ultimately exhaust available space. In southern Spain, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of European endemics (only found in Europe) facing extinction.
In the Mediterranean area, species such as the highly at-risk Karpathos grayling are threatened by extreme drought and wildfires.
In the meantime, in the Arctic Circle, climate change is resulting in the timberline to advance northwards by many meters each year, with scrub taking over marsh and tundra. Higher temperatures also mean Arctic deer can no more cross the ice sheets to browse northern grasslands and keep them open. 8 butterfly varieties are facing extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The biggest living space for all these pollinators is flower-rich grassland and that is disappearing very fast throughout Europe because of all these elements,” stated one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many people are aware now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all participating nations have to turn around the drop in pollinating species by 2030, and they are going to have to begin taking action. There are landowners who are engaged. We hope they can get the motivations that will assist them on their way.”
As stated by Warren, there is “readily achievable actions” in terms of steps for pollinating insects which won’t reduce agricultural output – and might boost it – such as growers developing flower-rich margins around their farmland.
EU commissioner for environment, portrayed the preservation condition of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is required to confront this danger. In collaboration with participating nations, the EU Commission has implemented an Europe-wide tracking system for pollinators based on the EU nature restoration law, which will help to track our development. Now, we need to concentrate on execution and cooperation with participating nations to protect our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies comes after the first Europe-wide evaluation of hoverflies, another crucial pollinator group. Issued in twenty-twenty-two, it revealed that over one-third of all hoverfly species in the European continent were at risk of extinction.
