The count of non-managed bee types in European nations experiencing dying out has increased twofold over the past decade, while the total of at-risk butterfly types has nearly doubled.
This dire scenario for vital pollinating species was revealed by scientific studies for the IUCN red list, which determined that at least one hundred seventy-two bee species out of 1,928 were threatened with extinction in Europe.
The number of butterfly types facing extinction in the European continent has increased from thirty-seven to over sixty since the previous assessment, carried out 14 years ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
In addition to their beauty and cultural significance, pollinators like bees and butterflies are lifelines for our health, our food chains and our economies – sustaining the produce, vegetables and seeds that sustain us,” commented Grethel Aguilar. “The most recent European red list assessments reveal serious challenges, with dangers growing for butterflies and crucial native bee varieties.”
The factors of the rapid recent declines are the persistent harm or degradation of living environments caused by farming intensification and deserted farmland, draining of wetlands, excessive grazing by animals, and the utilization of pesticides and fertilisers including neonicotinoid pesticides. The fragmentation of habitat friendly to pollinators greatly increases the risk of local extinctions.
Climate change is also shown to be a major threat: Over half of all endangered butterfly types in European nations are imperilled by the climate crisis – approximately twice as many as a previous decade.
Up to ninety percent of blooming plants in Europe depend on insect pollination, according to Dr Denis Michez. “Sadly, native bee colonies are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If wild bees vanish, many native plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a handful of illustrations.”
Fifteen species of bumblebees, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and fourteen varieties 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 type exclusive to the continent and the sole species of this genus group in European nations, is now evaluated as critically endangered – the scientific category nearest to dying out in natural habitats.
Butterfly species that are solely present on high-altitude areas are especially at risk to climate change as they must ascend higher as their habitats become warmer but ultimately run out of space. In Spain’s southern region, the grayling of Nevada and the anomalous blue of Andalusia are among above 40 percent of European endemics (exclusive to Europe) facing extinction.
In the Mediterranean area, types such as the highly at-risk Karpathos grayling are threatened by severe drought and wildfires.
Meanwhile, in the Far North, climate change is resulting in the forest boundary to advance northwards by tens of metres each year, with bushes taking over wetlands and tundra. Hotter climates also mean reindeer can no longer cross the ice to browse northern grasslands and keep them open. 8 butterfly varieties are at risk of extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The biggest environment for all these pollinating species is flower-rich grassland and that is vanishing rapidly in European nations because of all these elements,” stated one of the lead coordinators of the butterflies assessment. “The good news is that so many individuals 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 pollinators by 2030, and they are going to have to initiate measures. There are land holders who are interested. We hope they can obtain the motivations that will assist them on their way.”
As per Martin Warren, there is “low-hanging fruit” in terms of measures for pollinating species which will not decrease food production – and might boost it – such as growers establishing margins rich in flowers around their farmland.
EU commissioner for environment, described the preservation condition of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Prompt and unified steps is necessary to confront this risk. Along with participating nations, the Commission of the European Union has implemented an European Union-wide monitoring system for pollinating insects based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to focus on application and collaboration with participating nations to safeguard our pollinating species,” she said.
The publication of the evaluations of bees along with butterflies is subsequent to the pioneering Europe-wide assessment of hoverflies, a further essential group of pollinators. Published in twenty-twenty-two, it showed that 37% of all hoverfly varieties in the European continent were threatened with extinction.
