The count of wild bee varieties in European nations experiencing extinction has more than doubled during the previous ten-year period, while the total of at-risk butterfly has almost doubled.
This critical situation for crucial pollinating species was disclosed by research studies for the IUCN red list, which determined that at least 172 bee types out of 1,928 were facing extinction in Europe.
The count of butterflies at risk of extinction in the European continent has grown from thirty-seven to sixty-five since the earlier research, performed 14 years ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
Apart from their visual charm and cultural value, pollinators like bees and butterfly species are crucial elements for our well-being, our food supplies and our economic systems – sustaining the fruits, veggies and seeds that nourish us,” said the IUCN director general. “The latest assessments of the European red list reveal significant difficulties, with risks increasing for butterflies and essential non-managed bee varieties.”
The factors of the rapid recent declines are the continuing destruction or damage of natural habitats caused by intensive agriculture and land abandonment, wetland drainage, overgrazing by livestock, and the application of fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of habitat friendly to pollinators significantly raises the threat of local extinctions.
Climate change is also shown to be a significant danger: Over half of all endangered butterfly types in Europe are imperilled by the climate change crisis – approximately double the number as a ten years ago.
Up to 90% of blooming plants in European nations rely on pollination by animals, as per Dr Denis Michez. “Sadly, non-managed bee groups are in sharp decrease and cannot readily be substituted by managed colonies,” he said. “If wild bees vanish, many non-cultivated plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebees, which have an essential part in pollinating legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for aiding tree pollination such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee found only in the continent and the sole species of this genus in European nations, is now assessed as severely threatened – the research category closest to extinction in the wild.
Butterfly types that are solely present on high-altitude areas are especially at risk to global heating as they must ascend higher as their living spaces become warmer but eventually exhaust available space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (only found in Europe) at risk of extinction.
In the Mediterranean region, types such as the critically endangered Karpathos grayling are endangered by extreme wildfires and drought.
In the meantime, in the Arctic region, climate change is leading to the timberline to shift northward by many meters each year, with underbrush invading bog and tundra. Higher temperatures also mean Arctic deer can no longer cross the frozen water to graze Arctic meadows and maintain them clear. 8 butterfly varieties are at risk of extinction in this area, including Freyja’s fritillary and the Arctic ringlet.
“The largest habitat for all these pollinating species is grassland rich in flowers and that is declining quickly in Europe because of all these reasons,” remarked Martin Warren. “The encouraging aspect is that so many citizens are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to halt the drop in pollinating insects by 2030, and they are going to have to begin taking action. There are landowners who are interested. Let’s hope they can get the motivations that will help them on their way.”
According to the coordinator, there is “readily achievable actions” in terms of steps for pollinators which will not lower food production – and could improve it – such as growers creating margins rich in flowers around their farmland.
the EU’s environment commissioner, portrayed the protection status of native bees, butterflies and additional pollinators as “critical”.
“Urgent and collective action is needed to address this risk. In collaboration with member states, the EU Commission has implemented an Europe-wide tracking system for pollinating species based on the EU nature restoration law, which will help to track our advancement. Now, we need to concentrate on implementation and cooperation with member countries to safeguard our pollinating species,” she said.
The release of the assessments on bees and butterflies follows the first European-wide evaluation of hoverflies, an additional vital pollinator group. Issued in twenty-twenty-two, it showed that 37% of all hoverfly varieties in European nations were at risk of extinction.
