The count of wild bee types in the European continent confronting dying out has over doubled over the past decade, and the total of endangered butterfly has close to doubled.
This pressing issue for essential pollinators was revealed by scientific assessments for the red list of threatened species, which determined that at least one hundred seventy-two bee varieties out of nearly two thousand were at risk of extinction in European nations.
The count of butterfly types at risk of extinction in the European continent has risen from thirty-seven to sixty-five since the earlier research, performed over a decade past. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
Apart from their aesthetic appeal and cultural importance, pollinating species like bees along with butterflies are lifelines for our health, our food chains and our economic systems – sustaining the fruits, vegetables and seeds that nourish us,” stated the IUCN director general. “The latest European red list evaluations reveal significant difficulties, with threats mounting for butterfly types and vital native bee types.”
The reasons of the quick recent decreases are the continuing damage or destruction of living environments caused by agricultural intensification and deserted farmland, draining of wetlands, excessive grazing by animals, and the application of fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of pollinator-friendly habitat greatly increases the risk of extinctions at local level.
Global heating is also shown to be a major threat: 52% of all threatened butterfly types in the European continent are endangered by the climate emergency – roughly twofold the amount as a previous decade.
As many as nine out of ten of blooming plants in the European continent rely on insect pollination, according to the wild bee assessment’s lead coordinator. “Regrettably, wild bee populations are in drastic decline and cannot readily be substituted by domesticated hives,” he said. “If wild bees disappear, many wild plants might be in danger as well – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen types of bumblebee types, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee species, famous for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the single type of this genus in Europe, is now classified as critically at risk – the scientific classification closest to extinction in the wild.
Butterflies that are only found on mountain peaks are especially at risk to global heating as they need to move uphill as their living spaces become warmer but in the end run out of space. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among above 40 percent of European endemics (only found in Europe) threatened with extinction.
In the Mediterranean region, types such as the severely threatened Karpathos grayling are imperilled by severe dry conditions and fires.
Meanwhile, in the Arctic region, global warming is leading to the timberline to shift northward by many meters each year, with underbrush taking over marsh and tundra. Warmer conditions also mean Arctic deer can not anymore cross the frozen water to graze Arctic grasslands and maintain them clear. Eight types of butterflies are facing extinction in this area, including Freyja’s fritillary and the ringlet of the Arctic.
“The largest living space for all these pollinating species is bloom-filled grassy areas and that is disappearing very fast throughout Europe because of all these elements,” said a lead coordinator for the butterfly assessment. “The positive thing is that so many people are concerned now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all member states have to reverse the decline in pollinators by 2030, and they are going to have to begin taking action. There are landowners who are interested. We hope they can receive the motivations that will help them on their way.”
As stated by Warren, there is “easy opportunities” in terms of steps for pollinating species which will not lower agricultural output – and may enhance it – such as growers developing margins rich in flowers around their farmland.
EU commissioner for environment, described the conservation status of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is needed to confront this risk. Together with member states, the Commission of the European Union has put in place an EU-wide monitoring system for pollinating species based on the EU nature restoration regulation, which will aid in following our progress. Now, we need to prioritize implementation and collaboration with member states to protect our pollinators,” she said.
The issuance of the evaluations of bees along with butterflies follows the initial EU-wide study on hoverflies, a further vital group of pollinators. Issued in 2022, it revealed that 37% of all hoverfly types in Europe were at risk of extinction.
