The number of non-managed bee varieties in Europe experiencing dying out has over doubled over the past decade, while the total of endangered butterfly has almost doubled.
This pressing issue for essential pollinating species was revealed by scientific studies for the IUCN red list, which determined that at least one hundred seventy-two bee species out of over 1900 were facing extinction in European nations.
The count of butterflies threatened with extinction in Europe has grown from thirty-seven to over sixty since the last study, carried out a decade and a half ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural importance, pollinating species like bees and butterfly species are lifelines for our well-being, our food systems and our economies – sustaining the produce, vegetables and seeds that sustain us,” commented Grethel Aguilar. “The most recent European red list assessments reveal significant difficulties, with threats mounting for butterfly types and essential non-managed bee types.”
The factors of the quick recent decreases are the continuing damage or destruction of living environments caused by agricultural intensification and abandoned land, draining wetlands, excessive grazing by animals, and the use of pesticides and fertilisers including neonicotinoids. The division of pollinator-friendly habitat significantly raises the threat of disappearances in specific areas.
Climate change is also demonstrated to be a major threat: 52% of all threatened butterflies in European nations are endangered by the climate change crisis – approximately twofold the amount as a decade ago.
As many as ninety percent of plants that flower in European nations rely on animal pollination, according to the wild bee assessment’s lead coordinator. “Sadly, native bee groups are in sharp decrease and are not easily replaceable by managed bee colonies,” he said. “If wild bees disappear, many native plants might be threatened too – of which flower-rich meadows and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee types, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bees, famous for aiding tree pollination such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the European continent and the single type of this biological genus in European nations, is now classified as critically at risk – the research category closest to extinction in the wild.
Butterfly types that are exclusively located on high-altitude areas are especially at risk to global warming as they have to climb upward as their environments become warmer but eventually exhaust available space. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (solely present in Europe) facing extinction.
In the Mediterranean region, species such as the highly at-risk Karpathos grayling are endangered by severe dry conditions and fires.
At the same time, in the Far North, climate change is leading to the timberline to move north by many meters each year, with scrub invading wetlands and tundra. Hotter climates also mean reindeer can no longer cross the frozen water to browse northern grasslands and maintain them clear. 8 butterfly varieties are facing extinction in this zone, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The greatest habitat for all these pollinating insects is bloom-filled grassy areas and that is disappearing very fast throughout Europe because of all these factors,” stated one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many citizens care now and there’s a lot more understanding. Under the European Union nature restoration law, all participating nations have to halt the decrease in pollinating insects by the year 2030, and they are going to have to begin taking action. There are landowners who are interested. Let’s hope they can obtain the encouragements that will assist them on their way.”
As per Warren, there is “low-hanging fruit” in terms of steps for pollinating species which will not decrease crop yields – and could improve it – such as agricultural producers establishing flower-rich margins around their farmland.
the EU’s environment commissioner, described the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is necessary to confront this danger. Along with member countries, the EU Commission has put in place an EU-wide monitoring system for pollinating insects based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to concentrate on implementation and partnership with member countries to preserve our pollinators,” she said.
The publication of the assessments on bees and butterflies is subsequent to the first EU-wide study on hoverflies, another crucial group of pollinators. Issued in 2022, it revealed that thirty-seven percent of all hoverfly varieties in the European continent were facing extinction.
