The total of native bee types in European nations facing disappearance has increased twofold in the last ten years, while the total of endangered butterfly has almost doubled.
This pressing issue for crucial pollinating species was revealed by scientific assessments for the red list of threatened species, which found that at least one hundred seventy-two bee species out of over 1900 were at risk of extinction in the European continent.
The number of butterfly species threatened with extinction in European nations has increased from over thirty-five to 65 since the last study, performed 14 years ago. One species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
Apart from their beauty and cultural significance, pollinators like bees along with butterflies are lifelines for our health, our food systems and our economic systems – maintaining the produce, vegetables and seeds that sustain us,” stated the IUCN’s director general. “The most recent assessments of the European red list reveal significant difficulties, with dangers mounting for butterflies and essential wild bee species.”
The factors of the quick recent decreases are the continuing damage or destruction of habitats caused by agricultural intensification and abandoned land, wetland drainage, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoids. The division of pollinator-friendly habitat significantly raises the danger of disappearances in specific areas.
Global heating is also shown to be a significant danger: Fifty-two percent of all threatened butterflies in Europe are endangered by the climate emergency – approximately twice as many as a previous decade.
Up to ninety percent of blooming plants in the European continent require pollination by animals, as per the wild bee assessment’s lead coordinator. “Unfortunately, native bee colonies are in severe drop and are not easily replaceable by managed bee colonies,” he said. “If native bees vanish, many wild plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebees, which perform a vital function in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, recognized for pollinating trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the mainland and the single type of this genus group in the European continent, is now classified as critically at risk – the scientific classification most akin to disappearance in the wild.
Butterflies that are exclusively located on high-altitude areas are especially at risk to climate change as they need to move uphill as their habitats become hotter but in the end have no room left. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue are among more than 40% of species endemic to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean region, varieties such as the critically endangered Karpathos grayling butterfly are imperilled by extreme wildfires and drought.
In the meantime, in the Arctic region, global warming is causing the timberline to advance northwards by dozens of meters each year, with underbrush taking over bog and tundra. Higher temperatures also mean caribou can no more cross the ice to feed on northern grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this zone, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The biggest environment for all these pollinating insects is bloom-filled grassy areas and that is vanishing rapidly in European nations because of all these reasons,” stated Martin Warren. “The positive thing is that so many individuals care now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all member countries have to turn around the decline in pollinators by 2030, and they are going to have to start doing something. There are landowners who are interested. We hope they can receive the incentives that will support them on their way.”
As stated by Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which will not decrease agricultural output – and might boost it – such as farmers establishing margins rich in flowers around their fields.
EU commissioner for environment, portrayed the protection status of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is necessary to address this danger. Together with participating nations, the Commission of the European Union has established an Europe-wide tracking system for pollinating insects based on the EU nature restoration regulation, which will help to track our progress. Now, we need to concentrate on execution and cooperation with participating nations to protect our pollinating species,” she said.
The issuance of the bee and butterfly assessments follows the initial Europe-wide assessment of hoverflies, another crucial pollinator group. Issued in 2022, it disclosed that 37% of all hoverfly varieties in European nations were facing extinction.
