The count of non-managed bee types in the European continent experiencing disappearance has increased twofold over the past decade, while the number of threatened butterfly species has almost doubled.
This dire scenario for essential pollinating species was disclosed by research studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least one hundred seventy-two bee species out of nearly two thousand were facing extinction in the European continent.
The number of butterfly types facing extinction in European nations has increased from over thirty-five to over sixty since the last study, conducted a decade and a half ago. A single species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
“Beyond their aesthetic appeal and cultural value, pollinators like bees and butterfly species are essential supports for our well-being, our food chains and our economic systems – sustaining the fruits, vegetables and seeds that sustain us,” said the IUCN’s director general. “The latest European red list assessments reveal serious challenges, with dangers growing for butterfly types and vital non-managed bee varieties.”
The reasons of the swift recent drops are the continuing destruction or damage of habitats caused by farming intensification and land abandonment, draining wetlands, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoid pesticides. The division of habitat friendly to pollinators substantially boosts the threat of local extinctions.
Climate change is also shown to be a major threat: Fifty-two percent of all threatened butterfly species in Europe are endangered by the climate emergency – roughly twice as many as a ten years ago.
Nearly ninety percent of plants that flower in Europe depend on insect pollination, as stated by Dr Denis Michez. “Regrettably, native bee populations are in drastic decline and cannot be easily replaced by managed bee colonies,” he said. “If non-managed bees die out, many wild plants might be in danger as well – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
Fifteen species of bumblebee types, which have an essential part in fertilizing peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, known for pollinating trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type found only in the continent and the only species of this genus group in European nations, is now classified as severely threatened – the scientific classification nearest to disappearance in the wild.
Butterfly species that are exclusively located on high-altitude areas are especially at risk to global warming as they have to climb upward as their habitats become warmer but in the end run out of space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of European endemics (exclusive to Europe) threatened with extinction.
In the Mediterranean region, types such as the highly at-risk Karpathos grayling are endangered by intense dry conditions and fires.
At the same time, in the Arctic region, global heating is leading to the timberline to shift northward by many meters each year, with underbrush invading bog and tundra. Hotter climates also mean reindeer can not anymore cross the frozen water to graze Arctic meadows and maintain them clear. Eight types of butterflies are at risk of extinction in this area, including the fritillary of Freyja and the ringlet of the Arctic.
“The greatest environment for all these pollinators is bloom-filled grassy areas and that is disappearing very fast across European nations because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many citizens are aware now and there’s a lot more understanding. Under the European Union nature restoration law, all member states have to reverse the drop in pollinating insects by 2030, and they are going to have to initiate measures. There are landowners who are involved. It is hoped they can receive the motivations that will assist them on their way.”
According to Warren, there is “readily achievable actions” in terms of action for pollinating species which won’t reduce agricultural output – and might boost it – such as growers developing margins rich in flowers around their cultivated areas.
EU commissioner for environment, portrayed the conservation status of wild bees, butterflies and other pollinators as “critical”.
“Urgent and collective action is necessary to confront this threat. Together with participating nations, the EU Commission has implemented an Europe-wide tracking system for pollinating species based on the European Union nature restoration legislation, which will assist in monitoring our progress. Now, we need to focus on implementation and partnership with member countries to protect our pollinators,” she said.
The issuance of the bee and butterfly assessments is subsequent to the pioneering EU-wide study on hoverflies, an additional essential group of pollinators. Published in twenty-twenty-two, it disclosed that 37% of all hoverfly varieties in European nations were facing extinction.
