The count of native bee varieties in European nations confronting extinction has increased twofold during the previous ten-year period, and the total of at-risk butterfly species has nearly doubled.
This critical situation for vital pollinators was unveiled by scientific assessments for the red list of threatened species, which established that at least over 170 bee species out of 1,928 were threatened with extinction in European nations.
The total of butterfly types at risk of extinction in Europe has risen from over thirty-five to 65 since the last study, carried out over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their visual charm and cultural significance, pollinators like bees along with butterflies are crucial elements for our physical condition, our food supplies and our financial structures – maintaining the fruits, vegetables and seeds that nourish us,” stated the IUCN’s director general. “The latest assessments of the European red list reveal serious challenges, with threats mounting for butterfly species and essential non-managed bee varieties.”
The factors of the quick recent decreases are the persistent harm or degradation of living environments caused by farming intensification and land abandonment, draining wetlands, livestock overgrazing, and the use of fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of pollinator-friendly habitat significantly raises the risk of disappearances in specific areas.
Global heating is also revealed to be a significant danger: Over half of all at-risk butterflies in the European continent are threatened by the climate change crisis – roughly twice as many as a previous decade.
As many as 90% of blooming plants in the European continent require animal pollination, as per Dr Denis Michez. “Sadly, native bee colonies are in severe drop and cannot be easily replaced by managed colonies,” he said. “If non-managed bees die out, many wild plants might be in danger as well – of which meadows rich in flowers and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebees, which play a crucial role in pollinating legumes like peas, beans, peanuts and clover, and 14 species of cellophane bees, recognized for pollinating trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species exclusive to the mainland and the only species of this genus in European nations, is now evaluated as severely threatened – the scientific category most akin to dying out in natural habitats.
Butterfly types that are only found on mountain tops are highly susceptible to climate change as they need to move uphill as their habitats become warmer but ultimately have no room left. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean area, types such as the critically endangered Karpathos grayling butterfly are endangered by severe drought and wildfires.
At the same time, in the Arctic Circle, global warming is resulting in the forest boundary to shift northward by many meters each year, with underbrush encroaching on marsh and tundra. Higher temperatures also mean Arctic deer can not anymore cross the ice to feed on Arctic grasslands and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.
“The largest living space for all these pollinating insects is grassland rich in flowers and that is vanishing rapidly throughout European nations because of all these elements,” said one of the lead coordinators of the butterflies assessment. “The positive thing is that so many individuals care now and there’s a lot more understanding. Under the European Union nature restoration law, all participating nations have to halt the drop in pollinating species by twenty-thirty, and they are going to have to initiate measures. There are landowners who are interested. It is hoped they can get the encouragements that will help them on their way.”
As per the coordinator, there is “easy opportunities” in terms of action for pollinators which will not lower food production – and might boost it – such as agricultural producers creating flower-rich margins around their farmland.
the EU’s environment commissioner, characterized the preservation condition of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Prompt and unified steps is required to confront this threat. Together with member countries, the EU Commission has established an EU-wide tracking system for pollinating species based on the EU nature restoration regulation, which will aid in following our progress. Now, we need to concentrate on application and cooperation with member countries to preserve our pollinating species,” she said.
The publication of the bee and butterfly assessments follows the first EU-wide study on hoverflies, an additional essential pollinating insect category. Published in 2022, it revealed that 37% of all hoverfly species in the European continent were threatened with extinction.
