The number of non-managed bee species in the European continent confronting disappearance has increased twofold over the past decade, whereas the number of at-risk butterfly species has nearly doubled.
This pressing issue for essential pollinators was unveiled by research studies for the IUCN red list, which established that at least 172 bee species out of over 1900 were at risk of extinction in the European continent.
The number of butterfly species at risk of extinction in Europe has grown from over thirty-five to over sixty since the last study, conducted 14 years ago. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
In addition to their aesthetic appeal and cultural value, pollinating species like bees along with butterflies are essential supports for our health, our food systems and our economies – supporting the fruits, veggies and seeds that nourish us,” stated Grethel Aguilar. “The latest European red list evaluations reveal significant difficulties, with threats growing for butterflies and vital wild bee types.”
The causes of the swift recent drops are the ongoing harm or degradation of habitats caused by farming intensification and deserted farmland, wetland drainage, livestock overgrazing, and the application of pesticides and fertilisers including neonicotinoid pesticides. The breaking up of habitat friendly to pollinators significantly raises the risk of disappearances in specific areas.
Global heating is also demonstrated to be a primary risk: Over half of all threatened butterflies in European nations are threatened by the climate change crisis – roughly twofold the amount as a ten years ago.
Up to nine out of ten of plants that flower in European nations require animal pollination, as stated by the lead coordinator of the wild bee assessment. “Sadly, wild bee colonies are in severe drop and cannot be easily replaced by managed bee colonies,” he said. “If wild bees die out, many non-cultivated plants might be threatened too – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
15 varieties of bumblebees, which play a crucial role in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for aiding tree pollination such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the single type of this genus group in European nations, is now classified as critically endangered – the scientific classification nearest to dying out in natural habitats.
Butterfly types that are solely present on mountain peaks are particularly vulnerable to climate change as they must ascend higher as their environments become more heated but ultimately exhaust available space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of European endemics (only found in Europe) threatened with extinction.
In the Mediterranean region, varieties such as the critically endangered grayling of Karpathos are imperilled by extreme wildfires and drought.
Meanwhile, in the Far North, climate change is leading to the tree line to shift northward by tens of metres each year, with underbrush taking over marsh and tundra. Higher temperatures also mean Arctic deer can no longer cross the frozen water to feed on Arctic grasslands and keep them open. Eight types of butterflies are at risk of extinction in this region, including the fritillary of Freyja and the Arctic ringlet.
“The largest environment for all these pollinators is flower-rich grassland and that is disappearing very fast in European nations because of all these reasons,” said Martin Warren. “The encouraging aspect is that so many people are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member countries have to reverse the decrease in pollinating insects by the year 2030, and they are going to have to initiate measures. There are landowners who are interested. We hope they can receive the incentives that will assist them on their way.”
As per Warren, there is “easy opportunities” in terms of measures for pollinating insects which will not lower food production – and may enhance it – such as growers establishing margins rich in flowers around their cultivated areas.
EU commissioner for environment, portrayed the protection status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Urgent and collective action is necessary to tackle this risk. Together with member countries, the EU Commission has put in place an European Union-wide tracking system for pollinators based on the European Union nature restoration legislation, which will aid in following our development. Now, we need to concentrate on application and partnership with participating nations to safeguard our pollinators,” she said.
The issuance of the bee and butterfly assessments comes after the first EU-wide evaluation of hoverflies, a further crucial pollinating insect category. Released in twenty-twenty-two, it revealed that thirty-seven percent of all hoverfly species in European nations were facing extinction.
