The total of non-managed bee species in the European continent facing dying out has more than doubled in the last ten years, and the total of threatened butterfly has close to doubled.
This pressing issue for crucial pollinators was unveiled by research studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least over 170 bee types out of 1,928 were at risk of extinction in the European continent.
The total of butterfly types facing extinction in European nations has increased from 37 to sixty-five since the earlier research, carried out over a decade past. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
Apart from their beauty and cultural value, pollinators like bees along with butterflies are lifelines for our well-being, our food chains and our financial structures – supporting the fruits, veggies and seeds that nourish us,” commented the IUCN’s director general. “The latest European red list evaluations reveal serious challenges, with threats mounting for butterfly types and crucial wild bee species.”
The causes of the quick recent decreases are the persistent harm or degradation of natural habitats caused by agricultural intensification and land abandonment, draining wetlands, livestock overgrazing, and the application of pesticides and fertilisers including neonicotinoid pesticides. The division of habitat friendly to pollinators greatly increases the risk of disappearances in specific areas.
Global warming is also shown to be a major threat: Over half of all at-risk butterfly types in European nations are threatened by the climate emergency – approximately twice as many as a decade ago.
Nearly nine out of ten of plants that flower in Europe require animal pollination, as stated by the wild bee assessment’s lead coordinator. “Unfortunately, native bee populations are in drastic decline and cannot readily be substituted by managed bee colonies,” he said. “If non-managed bees disappear, many non-cultivated plants might be at risk too – of which bloom-filled grasslands and attractive orchid varieties are just a few examples.”
Fifteen types of bumblebees, which have an essential part in fertilizing crops such as peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for fertilizing trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species unique to the continent and the only species of this genus in Europe, is now classified as critically at risk – the scientific category nearest to extinction in the wild.
Butterflies that are solely present on mountain tops are especially at risk to climate change as they must ascend higher as their living spaces become hotter but in the end run out of space. In the southern part of Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of European endemics (exclusive to Europe) at risk of extinction.
In the Mediterranean region, varieties such as the critically endangered Karpathos grayling butterfly are endangered by intense dry conditions and fires.
In the meantime, in the Arctic Circle, global warming is resulting in the forest boundary to shift northward by many meters each year, with scrub invading marsh and tundra. Higher temperatures also mean Arctic deer can no longer cross the frozen water to graze Arctic meadows and keep them open. Eight butterfly species are at risk of extinction in this area, including Freyja’s fritillary and the Arctic ringlet.
“The biggest living space for all these pollinating species is flower-rich grassland and that is declining quickly across Europe because of all these reasons,” said one of the lead coordinators of the butterflies assessment. “The good news is that so many individuals are concerned now and there’s a lot more consciousness. Under the European Union nature restoration law, all participating nations have to turn around the decline in pollinating insects by 2030, and they are going to have to begin taking action. There are landowners who are engaged. We hope they can get the motivations that will assist them on their way.”
According to Warren, there is “low-hanging fruit” in terms of steps for pollinating insects which won’t reduce crop yields – and may enhance it – such as farmers developing flower-rich margins around their farmland.
EU commissioner for environment, characterized the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Immediate and joint measures is necessary to address this risk. In collaboration with participating nations, the EU Commission has put in place an Europe-wide observation system for pollinating species based on the European Union nature restoration legislation, which will assist in monitoring our advancement. Now, we need to prioritize application and cooperation with member countries to preserve our pollinating species,” she said.
The release of the bee and butterfly assessments is subsequent to the initial EU-wide evaluation of hoverflies, another crucial pollinating insect category. Published in 2022, it disclosed that thirty-seven percent of all hoverfly types in Europe were facing extinction.
