The total of native bee species in European nations experiencing disappearance has increased twofold during the previous ten-year period, and the number of threatened butterfly has almost doubled.
This critical situation for crucial pollinators was disclosed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least 172 bee types out of nearly two thousand were threatened with extinction in the European continent.
The count of butterfly species facing extinction in Europe has increased from over thirty-five to 65 since the last study, carried out a decade and a half ago. One species, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural importance, pollinating insects like bees and butterfly species are essential supports for our physical condition, our food chains and our financial structures – supporting the produce, vegetables and seeds that feed us,” said the IUCN director general. “The latest European red list assessments reveal significant difficulties, with dangers mounting for butterfly species and vital wild bee species.”
The factors of the swift recent drops are the continuing harm or degradation of living environments caused by agricultural intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the utilization of chemical fertilisers and pesticides including neonicotinoids. The breaking up of pollinator-friendly habitat substantially boosts the danger of extinctions at local level.
Global heating is also shown to be a primary risk: 52% of all at-risk butterfly species in Europe are endangered by the climate crisis – roughly twofold the amount as a previous decade.
Nearly 90% of flowering plants in Europe rely on insect pollination, as stated by the lead coordinator of the wild bee assessment. “Unfortunately, non-managed bee colonies are in sharp decrease and cannot readily be substituted by managed colonies,” he said. “If native bees die out, many native plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a few examples.”
Fifteen types of bumblebee types, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and 14 species of cellophane bees, known for pollinating trees such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the European continent and the sole species of this genus group in European nations, is now classified as critically endangered – the research category closest to extinction in the wild.
Butterfly types that are exclusively located on mountain peaks are especially at risk to climate change as they must ascend higher as their environments become more heated but eventually exhaust available space. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among more than 40% of types unique to Europe (exclusive to Europe) facing extinction.
In the Mediterranean region, species such as the critically endangered Karpathos grayling are imperilled by extreme drought and wildfires.
In the meantime, in the Arctic Circle, global warming is leading to the timberline to advance northwards by tens of metres each year, with underbrush invading bog and tundra. Hotter climates also mean reindeer can not anymore cross the ice to browse Arctic grasslands and keep them open. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The largest habitat for all these pollinators is grassland rich in flowers and that is declining quickly in European nations because of all these factors,” remarked a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many individuals care now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to reverse the decrease in pollinating species by twenty-thirty, and they are going to have to initiate measures. There are landowners who are engaged. Let’s hope they can receive the encouragements that will support them on their way.”
As stated by Warren, there is “easy opportunities” in terms of measures for pollinating species which will not lower food production – and may enhance it – such as growers developing flower-rich margins around their farmland.
the EU’s environment commissioner, characterized the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Urgent and collective action is necessary to tackle this danger. Along with member countries, the European Commission has established an EU-wide tracking system for pollinating insects based on the EU nature restoration law, which will aid in following our advancement. Now, we need to concentrate on execution and cooperation with member countries to protect our pollinating species,” she said.
The publication of the bee and butterfly assessments follows the initial Europe-wide evaluation of hoverflies, a further crucial group of pollinators. Issued in 2022, it showed that 37% of all hoverfly types in European nations were facing extinction.
