The total of native bee types in the European continent confronting disappearance has over doubled over the past decade, whereas the total of threatened butterfly has nearly doubled.
This pressing issue for vital pollinating species was unveiled by scientific assessments for the IUCN red list, which established that at least 172 bee types out of over 1900 were at risk of extinction in Europe.
The total of butterflies facing extinction in Europe has increased from over thirty-five to 65 since the previous assessment, performed a decade and a half ago. One type, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
In addition to their visual charm and cultural importance, pollinating insects like bees and butterfly species are crucial elements for our well-being, our food chains and our economies – maintaining the fruits, veggies and seeds that sustain us,” commented Grethel Aguilar. “The latest European red list assessments reveal serious challenges, with risks increasing for butterfly species and vital native bee varieties.”
The causes of the quick recent decreases are the continuing destruction or damage of natural habitats caused by agricultural intensification and deserted farmland, draining wetlands, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoids. The breaking up of habitat friendly to pollinators substantially boosts the danger of extinctions at local level.
Global heating is also revealed to be a major threat: Fifty-two percent of all at-risk butterfly species in Europe are endangered by the climate crisis – about double the number as a ten years ago.
As many as 90% of plants that flower in Europe depend on insect pollination, as per the wild bee assessment’s lead coordinator. “Unfortunately, wild bee colonies are in sharp decrease and cannot be easily replaced by managed bee colonies,” he said. “If native bees die out, many wild plants might be at risk too – of which flower-rich meadows and beautiful orchid species are just a couple of instances.”
15 varieties of bumblebees, which have an essential part in fertilizing crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, famous for aiding tree pollination such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the sole species of this genus group in European nations, is now evaluated as critically at risk – the research category most akin to extinction in the wild.
Butterfly types that are exclusively located on mountain peaks are especially at risk to global heating as they need to move uphill as their environments become warmer but in the end exhaust available space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean area, species such as the highly at-risk Karpathos grayling are threatened by extreme drought and wildfires.
At the same time, in the Arctic Circle, global warming is leading to the tree line to shift northward by tens of metres each year, with bushes invading bog and tundra. Hotter climates also mean reindeer can not anymore cross the ice sheets to feed on Arctic grasslands and maintain them clear. 8 butterfly varieties are at risk of extinction in this region, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The biggest habitat for all these pollinating species is flower-rich grassland and that is disappearing very fast across European nations because of all these reasons,” remarked one of the lead coordinators of the butterflies assessment. “The good news is that so many individuals are aware now and there’s a lot more awareness. Under the EU nature restoration legislation, all participating nations have to halt the decrease in pollinating species by twenty-thirty, and they are going to have to initiate measures. There are property owners who are interested. We hope they can get the motivations that will assist them on their way.”
As stated by Martin Warren, there is “easy opportunities” in terms of steps for pollinating species which will not lower crop yields – and could improve it – such as growers creating bloom-filled edges around their cultivated areas.
EU commissioner for environment, described the protection status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Immediate and joint measures is necessary to tackle this danger. In collaboration with participating nations, the European Commission has put in place an EU-wide monitoring system for pollinators based on the EU nature restoration law, which will help to track our advancement. Now, we need to focus on implementation and partnership with member states to protect our pollinating species,” she said.
The release of the assessments on bees and butterflies follows the first Europe-wide study on hoverflies, an additional crucial pollinating insect category. Released in 2022, it disclosed that thirty-seven percent of all hoverfly types in Europe were facing extinction.
