The total of non-managed bee species in the European continent experiencing extinction has increased twofold over the past decade, while the count of endangered butterfly has close to doubled.
This critical situation for crucial pollinating insects was disclosed by scientific studies for the IUCN red list, which determined that at least 172 bee species out of nearly two thousand were threatened with extinction in European nations.
The number of butterfly types at risk of extinction in European nations has risen from thirty-seven to sixty-five since the last study, conducted a decade and a half ago. One type, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
“Beyond their beauty and cultural value, pollinating insects like bees along with butterflies are crucial elements for our physical condition, our food supplies and our economic systems – supporting the fruits, veggies and seeds that sustain us,” stated the IUCN director general. “The newest European red list assessments reveal significant difficulties, with risks mounting for butterflies and essential wild bee varieties.”
The causes of the rapid recent declines are the continuing harm or degradation of habitats caused by agricultural intensification and deserted farmland, wetland drainage, livestock overgrazing, and the use of fertilisers and pesticides including neonicotinoid pesticides. The breaking up of habitat friendly to pollinators significantly raises the danger of extinctions at local level.
Climate change is also revealed to be a primary risk: Fifty-two percent of all at-risk butterfly types in Europe are threatened by the climate change crisis – approximately twofold the amount as a previous decade.
As many as ninety percent of blooming plants in the European continent rely on insect pollination, as stated by the wild bee assessment’s lead coordinator. “Sadly, wild bee colonies are in sharp decrease and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees die out, many native plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”
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 bees, known for aiding tree pollination such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the mainland and the only species of this biological genus in the European continent, is now assessed as critically endangered – the scientific category nearest to disappearance in the wild.
Butterfly species that are solely present on mountain peaks are highly susceptible to global warming as they need to move uphill as their environments become hotter but in the end exhaust available space. In Spain’s southern region, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (exclusive to Europe) facing extinction.
In the Mediterranean area, species such as the severely threatened Karpathos grayling butterfly are imperilled by extreme drought and wildfires.
At the same time, in the Arctic region, global warming is leading to the tree line to shift northward by many meters each year, with scrub invading wetlands and tundra. Hotter climates also mean caribou can no more cross the ice to graze Arctic grasslands and keep them open. Eight butterfly species are facing extinction in this region, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The biggest habitat for all these pollinators is grassland rich in flowers and that is declining quickly in European nations because of all these elements,” said a lead coordinator for the butterfly assessment. “The positive thing is that so many citizens are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all member states have to halt the decline in pollinating insects by the year 2030, and they are going to have to begin taking action. There are landowners who are engaged. It is hoped they can get the encouragements that will help them on their way.”
According to the coordinator, there is “easy opportunities” in terms of steps for pollinating insects which will not decrease food production – and may enhance it – such as agricultural producers establishing flower-rich margins around their fields.
the EU’s environment commissioner, portrayed the protection status of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is required to confront this threat. Together with participating nations, the European Commission has established an European Union-wide tracking system for pollinators based on the EU nature restoration law, which will help to track our progress. Now, we need to concentrate on application and collaboration with member countries to protect our pollinating species,” she said.
The publication of the assessments on bees and butterflies comes after the first Europe-wide evaluation of hoverflies, a further crucial pollinating insect category. Published in 2022, it disclosed that thirty-seven percent of all hoverfly species in the European continent were at risk of extinction.
