The number of wild bee types in the European continent confronting disappearance has over doubled over the past decade, and the total of threatened butterfly species has nearly doubled.
This dire scenario for crucial pollinating species was revealed by research studies for the IUCN red list, which found that at least one hundred seventy-two bee varieties out of nearly two thousand were at risk of extinction in European nations.
The total of butterflies at risk of extinction in the European continent has risen from 37 to sixty-five since the earlier research, performed a decade and a half ago. A single species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
“Beyond their aesthetic appeal and cultural value, pollinating species like bees and butterflies are lifelines for our physical condition, our food systems and our financial structures – maintaining the fruits, veggies and seeds that sustain us,” said the IUCN director general. “The newest assessments of the European red list reveal major obstacles, with risks mounting for butterfly types and vital non-managed bee varieties.”
The factors of the rapid recent declines are the ongoing damage or destruction of living environments caused by farming intensification and deserted farmland, wetland drainage, livestock overgrazing, and the use of pesticides and fertilisers including neonicotinoids. The breaking up of environments suitable for pollinators significantly raises the risk of disappearances in specific areas.
Global warming is also shown to be a significant danger: Fifty-two percent of all at-risk butterflies in the European continent are threatened by the climate change crisis – approximately twofold the amount as a ten years ago.
Nearly nine out of ten of blooming plants in European nations depend on animal pollination, according to Dr Denis Michez. “Sadly, native bee populations are in sharp decrease and are not easily replaceable by managed bee colonies,” he said. “If non-managed bees disappear, many non-cultivated plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”
Fifteen species of bumblebee species, which perform a vital function in fertilizing legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee types, recognized for aiding tree pollination such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type unique to the continent and the single type of this genus in European nations, is now evaluated as critically at risk – the scientific category nearest to extinction in the wild.
Butterfly species that are only found on high-altitude areas are particularly vulnerable to global heating as they have to climb upward as their habitats become warmer but ultimately exhaust available space. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue are among over forty percent of species endemic to Europe (only found in Europe) facing extinction.
In the Mediterranean region, species such as the highly at-risk Karpathos grayling butterfly are endangered by intense drought and wildfires.
In the meantime, in the Arctic Circle, climate change is resulting in the forest boundary to advance northwards by dozens of meters each year, with underbrush taking over wetlands and tundra. Higher temperatures also mean Arctic deer can not anymore cross the ice sheets to graze Arctic grasslands and keep them open. 8 butterfly varieties are facing extinction in this region, including the fritillary of Freyja and the ringlet of the Arctic.
“The greatest habitat for all these pollinators is flower-rich grassland and that is vanishing rapidly across European nations because of all these factors,” said Martin Warren. “The encouraging aspect is that so many people are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member countries have to halt the decline in pollinators by the year 2030, and they are going to have to begin taking action. There are landowners who are engaged. It is hoped they can obtain the motivations that will assist them on their way.”
According to Martin Warren, there is “low-hanging fruit” in terms of measures for pollinators which will not decrease crop yields – and could improve it – such as growers developing margins rich in flowers around their cultivated areas.
Jessika Roswall, described the preservation condition of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Urgent and collective action is needed to tackle this threat. Together with member countries, the European Commission has put in place an EU-wide observation system for pollinating species based on the EU nature restoration regulation, which will aid in following our development. Now, we need to prioritize application and partnership with member states to protect our pollinators,” she said.
The publication of the assessments on bees and butterflies follows the first EU-wide evaluation of hoverflies, a further crucial pollinator group. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly species in European nations were threatened with extinction.
