The total of non-managed bee types in Europe confronting extinction has over doubled in the last ten years, and the number of endangered butterfly has close to doubled.
This pressing issue for essential pollinating species was unveiled by research studies for the red list of threatened species, which established that at least over 170 bee varieties out of nearly two thousand were facing extinction in Europe.
The total of butterflies threatened with extinction in Europe has risen from thirty-seven to 65 since the last study, conducted a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
In addition to their visual charm and cultural value, pollinating insects like bees and butterfly species are lifelines for our well-being, our food systems and our economies – sustaining the fruits, vegetables and seeds that nourish us,” stated the IUCN director general. “The newest European red list assessments reveal major obstacles, with risks mounting for butterfly species and vital wild bee species.”
The reasons of the rapid recent declines are the ongoing destruction or damage of living environments caused by intensive agriculture and land abandonment, wetland drainage, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoid chemicals. The fragmentation of pollinator-friendly habitat substantially boosts the danger of extinctions at local level.
Global warming is also shown to be a primary risk: Fifty-two percent of all threatened butterfly species in Europe are imperilled by the climate emergency – about twice as many as a previous decade.
As many as ninety percent of plants that flower in the European continent require animal pollination, as per the wild bee assessment’s lead coordinator. “Sadly, non-managed bee groups are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If non-managed bees disappear, many native plants might be at risk too – of which flower-rich meadows and attractive orchid varieties are just a handful of illustrations.”
15 varieties of bumblebee types, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for aiding tree pollination such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type found only in the continent and the sole species of this genus in the European continent, is now evaluated as severely threatened – the scientific classification most akin to extinction in the wild.
Butterflies that are only found on high-altitude areas are highly susceptible to global warming as they need to move uphill as their habitats become hotter but in the end have no room left. In southern Spain, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean area, types such as the severely threatened grayling of Karpathos are threatened by extreme wildfires and drought.
In the meantime, in the Arctic Circle, global heating is causing the forest boundary to move north by dozens of meters each year, with underbrush taking over wetlands and tundra. Higher temperatures also mean Arctic deer can no longer cross the ice to browse Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this zone, including the fritillary of Freyja and the Arctic ringlet.
“The biggest environment for all these pollinating species is bloom-filled grassy areas and that is disappearing very fast throughout Europe because of all these elements,” remarked Martin Warren. “The good news is that so many people are aware now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to turn around the decline in pollinating species by twenty-thirty, and they are going to have to initiate measures. There are property owners who are interested. Let’s hope they can get the motivations that will help them on their way.”
According to Martin Warren, there is “easy opportunities” in terms of action for pollinators which will not decrease agricultural output – and might boost it – such as farmers establishing margins rich in flowers around their cultivated areas.
EU commissioner for environment, characterized the conservation status of native bees, butterflies and additional pollinators as “dire”.
“Immediate and joint measures is necessary to confront this danger. In collaboration with member states, the European Commission has established an European Union-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will help to track our development. Now, we need to concentrate on execution and partnership with participating nations to preserve our pollinating insects,” she said.
The publication of the bee and butterfly assessments comes after the first European-wide assessment of hoverflies, a further crucial pollinating insect category. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly species in European nations were facing extinction.
