The total of wild bee types in Europe experiencing dying out has more than doubled in the last ten years, whereas the number of at-risk butterfly species has nearly doubled.
This dire scenario for vital pollinating species was revealed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least over 170 bee types out of 1,928 were facing extinction in Europe.
The count of butterfly types facing extinction in the European continent has risen from thirty-seven to over sixty since the previous assessment, carried out a decade and a half ago. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
“Beyond their beauty and cultural significance, pollinating insects like bees and butterflies are lifelines for our health, our food chains and our economies – sustaining the fruits, vegetables and seeds that nourish us,” commented the IUCN director general. “The most recent European red list evaluations reveal serious challenges, with risks increasing for butterfly types and vital native bee types.”
The factors of the rapid recent declines are the persistent harm or degradation of natural habitats caused by intensive agriculture and deserted farmland, draining of wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The division of habitat friendly to pollinators significantly raises the threat of disappearances in specific areas.
Global heating is also revealed to be a significant danger: 52% of all at-risk butterfly species in European nations are endangered by the climate change crisis – about double the number as a previous decade.
Nearly ninety percent of plants that flower in European nations rely on insect pollination, as stated by the wild bee assessment’s lead coordinator. “Unfortunately, wild bee colonies are in drastic decline and are not easily replaceable by managed bee colonies,” he said. “If non-managed bees disappear, many non-cultivated plants might be in danger as well – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee species, which have an essential part in fertilizing peas, beans, peanuts and clover, and 14 species of cellophane bees, known for fertilizing trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the European continent and the sole species of this biological genus in European nations, is now classified as critically endangered – the scientific classification most akin to dying out in natural habitats.
Butterfly types that are solely present on high-altitude areas are highly susceptible to global warming as they must ascend higher as their habitats become more heated but ultimately run out of space. In Spain’s southern region, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean area, types such as the highly at-risk grayling of Karpathos are imperilled by extreme dry conditions and fires.
In the meantime, in the Far North, global heating is causing the tree line to move north by tens of metres each year, with underbrush taking over wetlands and tundra. Warmer conditions also mean caribou can no more cross the ice sheets to browse Arctic grasslands and prevent them from overgrowing. Eight butterfly species are facing extinction in this zone, including Freyja’s fritillary and the ringlet of the Arctic.
“The biggest habitat for all these pollinating species is bloom-filled grassy areas and that is disappearing very fast in Europe because of all these factors,” stated Martin Warren. “The positive thing is that so many people are concerned now and there’s a lot more understanding. Under the EU nature restoration legislation, all member states have to reverse the drop in pollinating species by 2030, and they are going to have to start doing something. There are landowners who are involved. It is hoped they can receive the motivations that will help them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which will not decrease food production – and may enhance it – such as growers developing margins rich in flowers around their fields.
the EU’s environment commissioner, portrayed the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Immediate and joint measures is required to address this danger. Along with member countries, the EU Commission has established an Europe-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will help to track our advancement. Now, we need to concentrate on implementation and cooperation with member countries to protect our pollinators,” she said.
The issuance of the bee and butterfly assessments is subsequent to the initial Europe-wide assessment of hoverflies, another essential group of pollinators. Issued in twenty-twenty-two, it showed that 37% of all hoverfly varieties in the European continent were threatened with extinction.
