The count of native bee species in European nations confronting extinction has over doubled in the last ten years, whereas the total of endangered butterfly has nearly doubled.
This dire scenario for crucial pollinating insects was revealed by research studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least over 170 bee species out of nearly two thousand were facing extinction in European nations.
The total of butterflies facing extinction in the European continent has risen from 37 to 65 since the last study, conducted 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
“Beyond their visual charm and cultural significance, pollinating insects like bees along with butterflies are essential supports for our well-being, our food systems and our economic systems – sustaining the fruits, veggies and seeds that feed us,” commented Grethel Aguilar. “The latest European red list assessments reveal major obstacles, with threats growing for butterfly species and vital wild bee species.”
The causes of the quick recent decreases are the continuing harm or degradation of living environments caused by intensive agriculture and land abandonment, draining of wetlands, excessive grazing by animals, and the use of chemical fertilisers and pesticides including neonicotinoid pesticides. The division of habitat friendly to pollinators greatly increases the danger of disappearances in specific areas.
Climate change is also shown to be a primary risk: Fifty-two percent of all endangered butterflies in the European continent are imperilled by the climate change crisis – approximately double the number as a previous decade.
As many as ninety percent of plants that flower in the European continent depend on animal pollination, as stated by the wild bee assessment’s lead coordinator. “Unfortunately, non-managed bee groups are in drastic decline and cannot be easily replaced by managed colonies,” he said. “If native bees vanish, many wild plants might be threatened too – of which meadows rich in flowers and beautiful orchid species are just a few examples.”
15 varieties of bumblebee species, which perform a vital function in pollinating legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee species, famous for pollinating trees such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the continent and the single type of this genus in the European continent, is now evaluated as severely threatened – the research category nearest to extinction in the wild.
Butterfly types that are only found on high-altitude areas are highly susceptible to climate change as they need to move uphill as their environments become hotter but in the end have no room left. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue butterfly are among more than 40% of European endemics (only found in Europe) at risk of extinction.
In the Mediterranean region, species such as the highly at-risk Karpathos grayling are imperilled by severe wildfires and drought.
At the same time, in the Arctic region, global warming is resulting in the forest boundary to shift northward by many meters each year, with underbrush invading marsh and tundra. Higher temperatures also mean reindeer can not anymore cross the ice sheets to browse Arctic grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this region, including Freyja’s fritillary and the Arctic ringlet.
“The largest habitat for all these pollinators is grassland rich in flowers and that is declining quickly in the European continent because of all these elements,” stated Martin Warren. “The positive thing is that so many individuals are concerned now and there’s a lot more consciousness. Under the EU nature restoration legislation, all participating nations have to halt the decline in pollinating species by the year 2030, and they are going to have to begin taking action. There are land holders who are involved. It is hoped they can get the encouragements that will assist them on their way.”
According to Warren, there is “easy opportunities” in terms of measures for pollinating species which will not decrease food production – and might boost it – such as growers developing bloom-filled edges around their fields.
the EU’s environment commissioner, described the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Urgent and collective action is needed to tackle this risk. Along with member countries, the Commission of the European Union has implemented an Europe-wide observation system for pollinating species based on the EU nature restoration law, which will help to track our advancement. Now, we need to prioritize execution and partnership with member states to safeguard our pollinating species,” she said.
The issuance of the evaluations of bees along with butterflies is subsequent to the first Europe-wide study on hoverflies, a further vital group of pollinators. Published in 2022, it showed that thirty-seven percent of all hoverfly types in European nations were facing extinction.
