The number of wild bee types in the European continent facing extinction has more than doubled in the last ten years, whereas the number of endangered butterfly has nearly doubled.
This pressing issue for crucial pollinators was revealed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which determined that at least one hundred seventy-two bee varieties out of nearly two thousand were at risk of extinction in European nations.
The count of butterfly species facing extinction in the European continent has risen from over thirty-five to sixty-five since the earlier research, performed over a decade past. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
Apart from their aesthetic appeal and cultural importance, pollinators like bees and butterflies are crucial elements for our health, our food systems and our economies – supporting the fruits, veggies and seeds that sustain us,” stated Grethel Aguilar. “The newest European red list assessments reveal major obstacles, with dangers mounting for butterfly types and essential wild bee types.”
The factors of the swift recent drops are the persistent destruction or damage of habitats caused by farming intensification and land abandonment, draining of wetlands, excessive grazing by animals, and the application of fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of environments suitable for pollinators significantly raises the danger of local extinctions.
Global warming is also shown to be a primary risk: Over half of all endangered butterflies in the European continent are imperilled by the climate change crisis – roughly twofold the amount as a ten years ago.
Up to nine out of ten of plants that flower in Europe depend on insect pollination, as stated by the lead coordinator of the wild bee assessment. “Sadly, non-managed bee colonies are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If non-managed bees disappear, many native plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a few examples.”
15 varieties of bumblebees, which play a crucial role in fertilizing peas, beans, peanuts and clover, and 14 types 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 found only in the European continent and the sole species of this biological genus in Europe, is now evaluated as critically at risk – the research category most akin to disappearance in the wild.
Butterflies that are exclusively located on high-altitude areas are especially at risk to global heating as they must ascend higher as their living spaces become hotter but in the end exhaust available space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among above 40 percent of types unique to Europe (only found in Europe) facing extinction.
In the Mediterranean, species such as the critically endangered Karpathos grayling butterfly are imperilled by extreme drought and wildfires.
Meanwhile, in the Arctic Circle, global warming is causing the timberline to advance northwards by many meters each year, with underbrush encroaching on bog and tundra. Warmer conditions also mean Arctic deer can not anymore cross the ice sheets to graze Arctic grasslands and maintain them clear. 8 butterfly varieties are facing extinction in this area, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The greatest living space for all these pollinating insects is bloom-filled grassy areas and that is declining quickly across the European continent because of all these elements,” said a lead coordinator for the butterfly assessment. “The positive thing is that so many individuals care now and there’s a lot more awareness. Under the EU nature restoration legislation, all member countries have to halt the decline in pollinating insects by twenty-thirty, and they are going to have to start doing something. There are property owners who are engaged. It is hoped they can get the motivations that will assist them on their way.”
According to Martin Warren, there is “low-hanging fruit” in terms of steps for pollinating species which will not lower crop yields – and may enhance it – such as farmers creating bloom-filled edges around their fields.
Jessika Roswall, characterized the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Urgent and collective action is required to address this danger. In collaboration with participating nations, the EU Commission has put in place an Europe-wide monitoring system for pollinating insects based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to concentrate on application and cooperation with member states to safeguard our pollinating insects,” she said.
The publication of the assessments on bees and butterflies follows the pioneering Europe-wide evaluation of hoverflies, another crucial group of pollinators. Issued in 2022, it revealed that over one-third of all hoverfly types in European nations were threatened with extinction.
