Worrying Surge in At-Risk Native Bee Species In the European Continent
The total of native bee species in Europe confronting disappearance has increased twofold over the past decade, and the number of at-risk butterfly species has almost doubled.
This pressing issue for essential pollinators was revealed by scientific studies for the red list of threatened species, which established that at least one hundred seventy-two bee types out of over 1900 were facing extinction in the European continent.
The number of butterfly species at risk of extinction in the European continent has increased from over thirty-five to over sixty since the earlier research, carried out over a decade past. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
“Beyond their beauty and cultural importance, pollinating insects like bees and butterfly species are crucial elements for our physical condition, our food systems and our financial structures – sustaining the fruits, veggies and seeds that sustain us,” stated the IUCN’s director general. “The most recent European red list evaluations reveal serious challenges, with risks mounting for butterflies and crucial non-managed bee types.”
The causes of the quick recent decreases are the ongoing harm or degradation of natural habitats caused by intensive agriculture and deserted farmland, draining of wetlands, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of environments suitable for pollinators greatly increases the threat of disappearances in specific areas.
Global warming is also revealed to be a major threat: 52% of all threatened butterflies in European nations are imperilled by the climate emergency – about twofold the amount as a ten years ago.
Nearly ninety percent of blooming plants in the European continent depend on pollination by animals, according to the lead coordinator of the wild bee assessment. “Sadly, native bee groups are in sharp decrease and are not easily replaceable by managed colonies,” he said. “If native bees vanish, many native plants might be at risk too – of which meadows rich in flowers and attractive orchid varieties are just a few examples.”
Fifteen species of bumblebees, which have an essential part in fertilizing legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for pollinating trees such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type unique to the mainland and the only species of this genus in Europe, is now classified as critically endangered – the scientific category closest to disappearance in the wild.
Butterfly species that are exclusively located on mountain peaks are particularly vulnerable to global warming as they have to climb upward as their environments become more heated but eventually run out of space. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean area, types such as the critically endangered Karpathos grayling are endangered by severe dry conditions and fires.
Meanwhile, in the Far North, global heating is leading to the timberline to shift northward by tens of metres each year, with scrub encroaching on wetlands and tundra. Hotter climates also mean reindeer can not anymore cross the frozen water to graze Arctic grasslands and maintain them clear. Eight types of butterflies are at risk of extinction in this area, 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 vanishing rapidly in Europe because of all these factors,” said one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all member countries have to halt the drop in pollinators by 2030, and they are going to have to initiate measures. There are land holders who are engaged. Let’s hope they can receive the motivations that will support them on their way.”
According to Warren, there is “readily achievable actions” in terms of action for pollinators which won’t reduce food production – and could improve it – such as growers establishing margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, characterized the protection status of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is needed to tackle this danger. In collaboration with member countries, the European Commission has implemented an European Union-wide tracking system for pollinators based on the EU nature restoration law, which will help to track our advancement. Now, we need to concentrate on execution and partnership with member countries to safeguard our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies is subsequent to the initial European-wide evaluation of hoverflies, another essential pollinator group. Published in 2022, it disclosed that thirty-seven percent of all hoverfly varieties in Europe were at risk of extinction.
