The total of native bee varieties in Europe experiencing disappearance has more than doubled in the last ten years, while the count of threatened butterfly has almost doubled.
This pressing issue for vital pollinating species was revealed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least one hundred seventy-two bee species out of 1,928 were at risk of extinction in the European continent.
The number of butterflies threatened with extinction in Europe has increased from over thirty-five to over sixty since the last study, conducted a decade and a half ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
In addition to their aesthetic appeal and cultural value, pollinating insects like bees along with butterflies are crucial elements for our physical condition, our food chains and our economies – supporting the produce, vegetables and seeds that sustain us,” commented the IUCN director general. “The newest assessments of the European red list reveal significant difficulties, with threats increasing for butterflies and crucial native bee types.”
The reasons of the quick recent decreases are the persistent damage or destruction of natural habitats caused by farming intensification and deserted farmland, draining wetlands, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoid pesticides. The division of pollinator-friendly habitat substantially boosts the threat of disappearances in specific areas.
Global warming is also revealed to be a significant danger: Fifty-two percent of all at-risk butterfly species in the European continent are threatened by the climate change crisis – roughly twice as many as a ten years ago.
As many as nine out of ten of blooming plants in Europe rely on pollination by animals, as per the lead coordinator of the wild bee assessment. “Unfortunately, wild bee groups are in drastic decline and cannot be easily replaced by managed bee colonies,” he said. “If native bees vanish, many native plants might be threatened too – of which bloom-filled grasslands and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebees, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, known for aiding tree pollination such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type found only in the mainland and the sole species of this genus group in European nations, is now assessed as severely threatened – the scientific category nearest to dying out in natural habitats.
Butterfly species that are exclusively located on mountain peaks are particularly vulnerable to global heating as they need to move uphill as their environments become hotter but ultimately run out of space. In the southern part of Spain, the grayling of Nevada and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean, types such as the severely threatened Karpathos grayling are threatened by extreme dry conditions and fires.
Meanwhile, in the Arctic region, climate change is causing the forest boundary to shift northward by dozens of meters each year, with bushes invading marsh and tundra. Higher temperatures also mean Arctic deer can no more cross the ice sheets to graze northern grasslands and keep them open. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The largest habitat for all these pollinating species is bloom-filled grassy areas and that is vanishing rapidly in European nations because of all these reasons,” stated one of the lead coordinators of the butterflies assessment. “The good news 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 reverse the drop in pollinators by the year 2030, and they are going to have to initiate measures. There are land holders who are interested. Let’s hope they can get the motivations that will assist them on their way.”
As per Martin Warren, there is “low-hanging fruit” in terms of action for pollinating insects which will not decrease crop yields – and might boost it – such as farmers creating flower-rich margins around their farmland.
Jessika Roswall, described the conservation status of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is required to confront this danger. In collaboration with participating nations, the European Commission has established an Europe-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will assist in monitoring our development. Now, we need to focus on execution and cooperation with member countries to safeguard our pollinating species,” she said.
The release of the assessments on bees and butterflies follows the initial EU-wide study on hoverflies, another vital pollinator group. Published in twenty-twenty-two, it revealed that 37% of all hoverfly species in Europe were threatened with extinction.
