The number of wild bee species in European nations confronting extinction has more than doubled over the past decade, whereas the total of endangered butterfly has nearly doubled.
This dire scenario for vital pollinators was revealed by research studies for the red list of threatened species, which determined that at least one hundred seventy-two bee types out of nearly two thousand were at risk of extinction in European nations.
The count of butterfly types facing extinction in the European continent has risen from thirty-seven to 65 since the earlier research, conducted over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural value, pollinators like bees and butterfly species are essential supports for our physical condition, our food systems and our economies – maintaining the produce, vegetables and seeds that sustain us,” said the IUCN’s director general. “The latest European red list evaluations reveal major obstacles, with threats mounting for butterfly types and vital wild bee species.”
The factors of the rapid recent declines are the continuing harm or degradation of habitats caused by agricultural intensification and abandoned land, wetland drainage, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoids. The fragmentation of environments suitable for pollinators greatly increases the threat of extinctions at local level.
Global warming is also shown to be a primary risk: 52% of all threatened butterflies in European nations are imperilled by the climate change crisis – approximately twofold the amount as a ten years ago.
As many as 90% of plants that flower in the European continent depend on pollination by animals, as per Dr Denis Michez. “Sadly, native bee colonies are in severe drop and cannot readily be substituted by managed bee 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.”
Fifteen species of bumblebees, which have an essential part in fertilizing 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 classified as threatened. Simpanurgus phyllopodus, a mining bee unique to the mainland and the single type of this genus in Europe, is now evaluated as critically endangered – the research category most akin to dying out in natural habitats.
Butterflies that are only found on mountain peaks are highly susceptible to global warming as they have to climb upward as their living spaces become warmer but ultimately exhaust available space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean region, varieties such as the critically endangered Karpathos grayling butterfly are threatened by intense dry conditions and fires.
At the same time, in the Far North, global heating is resulting in the forest boundary to advance northwards by many meters each year, with underbrush invading bog and tundra. Hotter climates also mean reindeer can no more cross the frozen water to graze Arctic grasslands and keep them open. Eight butterfly species are at risk of extinction in this region, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The biggest environment for all these pollinating species is bloom-filled grassy areas and that is declining quickly throughout European nations because of all these elements,” stated Martin Warren. “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 decline in pollinating species by twenty-thirty, and they are going to have to begin taking action. There are property owners who are interested. Let’s hope they can receive the incentives that will support them on their way.”
As per the coordinator, there is “low-hanging fruit” in terms of steps for pollinating insects which will not lower agricultural output – and might boost it – such as agricultural producers creating margins rich in flowers around their farmland.
EU commissioner for environment, described the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Immediate and joint measures is required to confront this risk. Together with participating nations, the European Commission has put in place an Europe-wide monitoring system for pollinating insects based on the EU nature restoration law, which will aid in following our advancement. Now, we need to focus on implementation and cooperation with member states to protect our pollinators,” she said.
The issuance of the bee and butterfly assessments comes after the first European-wide evaluation of hoverflies, a further vital pollinator group. Released in 2022, it disclosed that 37% of all hoverfly varieties in Europe were at risk of extinction.
