The total of non-managed bee species in European nations experiencing disappearance has over doubled over the past decade, while the count of at-risk butterfly has close to doubled.
This pressing issue for vital pollinating insects was unveiled by scientific assessments for the IUCN red list, which determined that at least one hundred seventy-two bee species out of nearly two thousand were threatened with extinction in the European continent.
The number of butterflies threatened with extinction in European nations has increased from over thirty-five to sixty-five since the earlier research, performed over a decade past. A single species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
Apart from their visual charm and cultural value, pollinating insects like bees and butterflies are crucial elements for our well-being, our food chains and our economic systems – sustaining the fruits, vegetables and seeds that sustain us,” commented the IUCN director general. “The most recent assessments of the European red list reveal significant difficulties, with threats increasing for butterflies and vital non-managed bee varieties.”
The reasons of the quick recent decreases are the ongoing damage or destruction of living environments caused by agricultural intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoid pesticides. The breaking up of pollinator-friendly habitat significantly raises the risk of disappearances in specific areas.
Global warming is also demonstrated to be a major threat: Over half of all threatened butterfly species in the European continent are imperilled by the climate emergency – roughly twice as many as a previous decade.
Up to nine out of ten of plants that flower in the European continent rely on insect pollination, according to Dr Denis Michez. “Unfortunately, native bee colonies are in severe drop and are not easily replaceable by managed bee colonies,” he said. “If native bees vanish, many wild plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a few examples.”
Fifteen species of bumblebee species, which play a crucial role in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for fertilizing trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the single type of this genus in the European continent, is now assessed as severely threatened – the scientific classification most akin to disappearance in the wild.
Butterflies that are solely present on mountain tops are particularly vulnerable to global heating as they have to climb upward as their environments become hotter but ultimately exhaust available space. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (exclusive to Europe) facing extinction.
In the Mediterranean area, types such as the severely threatened Karpathos grayling are threatened by severe wildfires and drought.
Meanwhile, in the Far North, global warming is resulting in the tree line to advance northwards by many meters each year, with scrub invading marsh and tundra. Higher temperatures also mean Arctic deer can no longer cross the ice sheets to feed on Arctic grasslands and maintain them clear. Eight types of butterflies are threatened with extinction in this zone, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The greatest living space for all these pollinating species is grassland rich in flowers and that is vanishing rapidly throughout the European continent because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The good news is that so many people care now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all participating nations have to turn around the decline in pollinating insects by twenty-thirty, and they are going to have to initiate measures. There are landowners who are interested. Let’s hope they can get the incentives that will help them on their way.”
As stated by Warren, there is “easy opportunities” in terms of action for pollinating species which won’t reduce crop yields – and might boost it – such as growers developing margins rich in flowers around their cultivated areas.
Jessika Roswall, portrayed the protection status of native bees, butterflies and additional pollinators as “dire”.
“Urgent and collective action is needed to confront this threat. Together with member countries, the Commission of the European Union has implemented an Europe-wide tracking system for pollinating insects based on the EU nature restoration law, which will help to track our progress. Now, we need to focus on implementation and collaboration with member states to protect our pollinators,” she said.
The issuance of the bee and butterfly assessments comes after the initial Europe-wide evaluation of hoverflies, another essential pollinating insect category. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly types in European nations were threatened with extinction.
