The number of wild bee varieties in Europe facing disappearance has increased twofold during the previous ten-year period, whereas the count of threatened butterfly has almost doubled.
This critical situation for vital pollinating insects was revealed by research studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least 172 bee varieties out of over 1900 were at risk of extinction in Europe.
The count of butterfly types at risk of extinction in European nations has grown from over thirty-five to 65 since the earlier research, performed a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their beauty and cultural significance, pollinating insects like bees along with butterflies are crucial elements for our health, our food chains and our financial structures – maintaining the fruits, veggies and seeds that nourish us,” commented the IUCN’s director general. “The most recent assessments of the European red list reveal major obstacles, with dangers growing for butterfly types and vital non-managed bee varieties.”
The factors of the quick recent decreases are the ongoing destruction or damage of habitats caused by farming intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the application of chemical fertilisers and pesticides including neonicotinoid pesticides. The division of pollinator-friendly habitat substantially boosts the danger of disappearances in specific areas.
Global heating is also demonstrated to be a major threat: 52% of all threatened butterflies in the European continent are imperilled by the climate emergency – about twice as many as a ten years ago.
Up to 90% of plants that flower in European nations depend on animal pollination, according to the lead coordinator of the wild bee assessment. “Unfortunately, non-managed bee populations are in severe drop and are not easily replaceable by managed bee colonies,” he said. “If native bees disappear, many wild plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a handful of illustrations.”
Fifteen types of bumblebees, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and 14 types of cellophane bee species, known for pollinating trees such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the single type of this genus in European nations, is now evaluated as critically endangered – the research category closest to disappearance in the wild.
Butterfly types that are solely present on mountain peaks are highly susceptible to global heating as they have to climb upward as their habitats become warmer but in the end exhaust available space. In the southern part of Spain, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of European endemics (only found in Europe) facing extinction.
In the Mediterranean region, types such as the critically endangered Karpathos grayling are threatened by severe drought and wildfires.
In the meantime, in the Arctic region, global heating is causing the tree line to shift northward by many meters each year, with scrub invading bog and tundra. Higher temperatures also mean Arctic deer can not anymore cross the ice sheets to feed on Arctic grasslands and keep them open. 8 butterfly varieties 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 pollinating species is bloom-filled grassy areas and that is declining quickly throughout Europe because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The good news is that so many citizens are aware now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to turn around the decline in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are landowners who are involved. We hope they can get the encouragements that will assist them on their way.”
As stated by Warren, there is “low-hanging fruit” in terms of action for pollinating insects which won’t reduce food production – and may enhance it – such as farmers creating margins rich in flowers around their cultivated areas.
the EU’s environment commissioner, characterized the conservation status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Immediate and joint measures is required to confront this danger. Along with member countries, the European Commission has established an EU-wide monitoring system for pollinating species based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to prioritize implementation and partnership with member countries to safeguard our pollinating insects,” she said.
The issuance of the evaluations of bees along with butterflies comes after the initial EU-wide assessment of hoverflies, an additional crucial group of pollinators. Released in 2022, it showed that 37% of all hoverfly types in the European continent were facing extinction.
