The number of wild bee varieties in Europe facing disappearance has increased twofold during the previous ten-year period, while the total of endangered butterfly types has close to doubled.
This pressing issue for vital pollinating insects was disclosed by scientific assessments for the IUCN red list, which determined that at least one hundred seventy-two bee varieties out of nearly two thousand were threatened with extinction in European nations.
The number of butterfly types threatened with extinction in Europe has increased from thirty-seven to 65 since the last study, carried out over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural importance, pollinators like bees and butterfly species are essential supports for our physical condition, our food systems and our financial structures – maintaining the fruits, veggies and seeds that sustain us,” stated the IUCN director general. “The newest assessments of the European red list reveal major obstacles, with risks growing for butterflies and vital wild bee varieties.”
The reasons of the swift recent drops are the ongoing destruction or damage of natural habitats caused by agricultural intensification and land abandonment, draining of wetlands, excessive grazing by animals, and the utilization of pesticides and fertilisers including neonicotinoid pesticides. The division of environments suitable for pollinators substantially boosts the danger of local extinctions.
Global heating is also shown to be a major threat: Over half of all endangered butterfly types in the European continent are endangered by the climate emergency – about double the number as a ten years ago.
Nearly 90% of flowering plants in Europe require animal pollination, as stated by Dr Denis Michez. “Unfortunately, non-managed bee populations are in sharp decrease and cannot readily be substituted by managed colonies,” he said. “If wild bees disappear, many native plants might be threatened too – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
15 varieties of bumblebee types, which perform a vital function in fertilizing legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, known for aiding tree pollination such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type found only in the continent and the only species of this biological genus in European nations, is now evaluated as critically endangered – the scientific classification most akin to dying out in natural habitats.
Butterfly species that are solely present on high-altitude areas are highly susceptible to global heating as they need to move uphill as their living spaces become hotter but eventually exhaust available space. In Spain’s southern region, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of species endemic to Europe (solely present in Europe) facing extinction.
In the Mediterranean, species such as the critically endangered grayling of Karpathos are threatened by intense wildfires and drought.
Meanwhile, in the Arctic Circle, global heating is causing the tree line to advance northwards by tens of metres each year, with scrub taking over marsh and tundra. Higher temperatures also mean reindeer can no more cross the frozen water to browse Arctic meadows and keep them open. 8 butterfly varieties are facing extinction in this area, including the fritillary of Freyja and the Arctic ringlet.
“The largest living space for all these pollinators is bloom-filled grassy areas and that is vanishing rapidly in the European continent because of all these elements,” remarked a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many citizens care now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all participating nations have to halt the decrease in pollinating insects by 2030, and they are going to have to begin taking action. There are land holders who are involved. We hope they can get the incentives that will support them on their way.”
As per Warren, there is “readily achievable actions” in terms of measures for pollinating species which won’t reduce food production – and might boost it – such as agricultural producers creating margins rich in flowers around their fields.
Jessika Roswall, described the preservation condition of native bees, butterflies and additional pollinators as “dire”.
“Immediate and joint measures is necessary to tackle this danger. Together with member countries, the EU Commission has put in place an European Union-wide observation system for pollinators based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to prioritize application and collaboration with member states to preserve our pollinating species,” she said.
The release of the assessments on bees and butterflies comes after the initial Europe-wide evaluation of hoverflies, an additional vital group of pollinators. Released in 2022, it disclosed that thirty-seven percent of all hoverfly types in the European continent were at risk of extinction.
