The total of native bee varieties in the European continent facing disappearance has more than doubled over the past decade, and the count of endangered butterfly types has almost doubled.
This dire scenario for essential pollinators was revealed by research studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least over 170 bee varieties out of nearly two thousand were at risk of extinction in Europe.
The total of butterfly species facing extinction in European nations has increased from thirty-seven to over sixty since the last study, conducted 14 years ago. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
Apart from their beauty and cultural value, pollinating insects like bees and butterflies are lifelines for our well-being, our food chains and our financial structures – sustaining the produce, vegetables and seeds that nourish us,” stated Grethel Aguilar. “The latest European red list evaluations reveal significant difficulties, with dangers increasing for butterflies and vital non-managed bee varieties.”
The factors of the rapid recent declines are the persistent harm or degradation of habitats caused by intensive agriculture and deserted farmland, wetland drainage, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The division of environments suitable for pollinators greatly increases the danger of disappearances in specific areas.
Global heating is also revealed to be a primary risk: 52% of all at-risk butterfly types in Europe are threatened by the climate change crisis – roughly twice as many as a decade ago.
Nearly ninety percent of blooming plants in the European continent depend on pollination by animals, according to Dr Denis Michez. “Sadly, non-managed bee groups are in severe drop and cannot readily be substituted by managed colonies,” he said. “If wild bees vanish, many wild plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebee species, which have an essential part in fertilizing legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for fertilizing trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the only species of this genus group in Europe, is now evaluated as critically at risk – the scientific category most akin to disappearance in the wild.
Butterfly types that are exclusively located on mountain tops are particularly vulnerable to global heating as they must ascend higher as their living spaces become warmer but eventually exhaust available space. In Spain’s southern region, the Nevada grayling butterfly and the Andalusian anomalous blue are among above 40 percent of species endemic to Europe (only found in Europe) threatened with extinction.
In the Mediterranean area, species such as the highly at-risk Karpathos grayling are endangered by extreme drought and wildfires.
Meanwhile, in the Arctic Circle, global heating is resulting in the timberline to advance northwards by tens of metres each year, with bushes encroaching on marsh and tundra. Warmer conditions also mean reindeer can no more cross the ice sheets to browse northern grasslands and prevent them from overgrowing. Eight types of butterflies are facing extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The biggest environment for all these pollinating species is bloom-filled grassy areas and that is disappearing very fast in the European continent because of all these factors,” stated a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many citizens care now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all participating nations have to halt the decline in pollinators by 2030, and they are going to have to initiate measures. There are land holders who are interested. We hope they can get the encouragements that will help them on their way.”
According to Martin Warren, there is “low-hanging fruit” in terms of steps for pollinators which won’t reduce crop yields – and might boost it – such as growers establishing margins rich in flowers around their farmland.
EU commissioner for environment, described the protection status of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is needed to confront this threat. In collaboration with member states, the Commission of the European Union has put in place an European Union-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will help to track our development. Now, we need to prioritize execution and partnership with participating nations to preserve our pollinating species,” she said.
The publication of the assessments on bees and butterflies follows the first European-wide evaluation of hoverflies, a further vital group of pollinators. Issued in 2022, it showed that thirty-seven percent of all hoverfly varieties in the European continent were threatened with extinction.
