The total of native bee types in the European continent facing dying out has more than doubled in the last ten years, and the total of threatened butterfly has nearly doubled.
This dire scenario for vital pollinating insects was disclosed by scientific assessments for the IUCN red list, which established that at least 172 bee varieties out of 1,928 were at risk of extinction in Europe.
The count of butterfly types at risk of extinction in European nations has risen from over thirty-five to 65 since the earlier research, conducted 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural value, pollinators like bees and butterflies are lifelines for our well-being, our food supplies and our economic systems – sustaining the produce, vegetables and seeds that feed us,” said the IUCN director general. “The newest European red list evaluations reveal significant difficulties, with risks increasing for butterflies and essential wild bee types.”
The reasons of the rapid recent declines are the continuing harm or degradation of living environments caused by agricultural intensification and land abandonment, draining of wetlands, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoid chemicals. The fragmentation of habitat friendly to pollinators greatly increases the risk of extinctions at local level.
Global heating is also revealed to be a significant danger: Fifty-two percent of all at-risk butterfly species in the European continent are imperilled by the climate change crisis – approximately twofold the amount as a decade ago.
Nearly ninety percent of plants that flower in Europe depend on animal pollination, according to the wild bee assessment’s lead coordinator. “Sadly, native bee colonies are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If native bees disappear, many native plants might be at risk too – of which meadows rich in flowers and beautiful orchid species are just a few examples.”
15 varieties of bumblebees, which have an essential part in fertilizing peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for pollinating trees such as willows along with red maples, are now listed as threatened. 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 scientific classification most akin to disappearance in the wild.
Butterflies that are solely present on mountain peaks are highly susceptible to climate change as they need to move uphill as their habitats become hotter but ultimately exhaust available space. In the southern part of Spain, the grayling of Nevada and the anomalous blue of Andalusia are among above 40 percent of types unique to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean, varieties such as the severely threatened grayling of Karpathos are threatened by extreme wildfires and drought.
At the same time, in the Far North, global heating is leading to the timberline to shift northward by tens of metres each year, with underbrush invading bog and tundra. Warmer conditions also mean Arctic deer can not anymore cross the ice to feed on Arctic grasslands and prevent them from overgrowing. Eight types of butterflies are threatened with extinction in this zone, including the fritillary of Freyja and the Arctic ringlet.
“The biggest living space for all these pollinating species is grassland rich in flowers and that is vanishing rapidly across Europe because of all these factors,” stated one of the lead coordinators of the butterflies assessment. “The positive thing is that so many people are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all participating nations have to reverse the drop in pollinators by the year 2030, and they are going to have to begin taking action. There are land holders who are engaged. We hope they can receive the incentives that will help them on their way.”
According to the coordinator, there is “easy opportunities” in terms of steps for pollinators which will not decrease food production – and might boost it – such as farmers developing flower-rich margins around their fields.
the EU’s environment commissioner, characterized the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Urgent and collective action is necessary to address this threat. In collaboration with member states, the Commission of the European Union has put in place an European Union-wide observation system for pollinating species based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to concentrate on execution and collaboration with participating nations to protect our pollinating species,” she said.
The issuance of the evaluations of bees along with butterflies is subsequent to the first Europe-wide evaluation of hoverflies, an additional vital pollinating insect category. Released in 2022, it revealed that over one-third of all hoverfly species in European nations were facing extinction.
