The count of non-managed bee varieties in Europe facing extinction has more than doubled during the previous ten-year period, whereas the number of endangered butterfly types has close to doubled.
This pressing issue for vital pollinators was revealed by research studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least 172 bee varieties out of 1,928 were facing extinction in Europe.
The number of butterfly species facing extinction in European nations has risen from 37 to over sixty since the previous assessment, conducted over a decade past. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
Apart from their beauty and cultural value, pollinating insects like bees along with butterflies are essential supports for our physical condition, our food supplies and our economic systems – supporting the produce, vegetables and seeds that nourish us,” commented Grethel Aguilar. “The latest assessments of the European red list reveal significant difficulties, with risks increasing for butterfly species and essential wild bee types.”
The reasons of the quick recent decreases are the continuing harm or degradation of habitats caused by agricultural intensification and abandoned land, draining wetlands, livestock overgrazing, and the application of pesticides and fertilisers including neonicotinoid pesticides. The breaking up of habitat friendly to pollinators greatly increases the danger of local extinctions.
Global warming is also revealed to be a primary risk: 52% of all threatened butterfly species in the European continent are imperilled by the climate change crisis – roughly double the number as a ten years ago.
As many as ninety percent of plants that flower in Europe rely on animal pollination, according to the wild bee assessment’s lead coordinator. “Sadly, non-managed bee populations are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If native bees vanish, many non-cultivated plants might be threatened too – of which meadows rich in flowers and beautiful orchid species are just a few examples.”
15 varieties of bumblebee types, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for pollinating trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the mainland and the only species of this genus group in European nations, is now assessed as critically at risk – the scientific classification closest to extinction in the wild.
Butterfly types that are exclusively located on high-altitude areas are highly susceptible to global warming as they have to climb upward as their habitats become more heated but eventually have no room left. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among over forty percent of types unique to Europe (solely present in Europe) facing extinction.
In the Mediterranean region, varieties such as the highly at-risk Karpathos grayling are endangered by severe wildfires and drought.
Meanwhile, in the Arctic region, global heating is resulting in the timberline to move north by dozens of meters each year, with underbrush invading wetlands and tundra. Warmer conditions also mean Arctic deer can no more cross the ice sheets to browse Arctic grasslands and maintain them clear. Eight butterfly species are threatened with extinction in this area, including the fritillary of Freyja and the Arctic ringlet.
“The greatest habitat for all these pollinating species is grassland rich in flowers and that is declining quickly in Europe because of all these elements,” stated one of the lead coordinators of the butterflies assessment. “The good news is that so many individuals are aware now and there’s a lot more awareness. Under the EU nature restoration legislation, all member states have to turn around the decline in pollinating insects by twenty-thirty, and they are going to have to initiate measures. There are property owners who are interested. We hope they can receive the encouragements that will assist them on their way.”
As stated by Warren, there is “easy opportunities” in terms of measures for pollinating insects which won’t reduce agricultural output – and may enhance it – such as agricultural producers developing flower-rich margins around their cultivated areas.
Jessika Roswall, portrayed the protection status of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is needed to tackle this danger. Together with participating nations, the Commission of the European Union has established an European Union-wide tracking system for pollinators based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to prioritize application and cooperation with member countries to protect our pollinating species,” she said.
The publication of the bee and butterfly assessments is subsequent to the first Europe-wide evaluation of hoverflies, an additional essential group of pollinators. Released in 2022, it disclosed that over one-third of all hoverfly varieties in European nations were threatened with extinction.
