The count of wild bee varieties in the European continent confronting disappearance has over doubled during the previous ten-year period, while the total of threatened butterfly types has almost doubled.
This dire scenario for essential pollinating insects was unveiled by research studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least 172 bee species out of nearly two thousand were facing extinction in the European continent.
The total of butterfly species at risk of extinction in the European continent has grown from thirty-seven to over sixty since the previous assessment, performed 14 years ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
“Beyond their visual charm and cultural value, pollinating species like bees and butterfly species are crucial elements for our physical condition, our food chains and our financial structures – sustaining the fruits, veggies and seeds that sustain us,” commented the IUCN’s director general. “The latest European red list evaluations reveal major obstacles, with dangers increasing for butterfly types and vital non-managed bee types.”
The causes of the quick recent decreases are the persistent harm or degradation of living environments caused by intensive agriculture and deserted farmland, draining wetlands, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoids. The division of environments suitable for pollinators substantially boosts the threat of disappearances in specific areas.
Global heating is also shown to be a major threat: Over half of all threatened butterflies in Europe are imperilled by the climate change crisis – about twice as many as a ten years ago.
As many as ninety percent of flowering plants in the European continent depend on pollination by animals, as stated by Dr Denis Michez. “Unfortunately, non-managed bee colonies are in sharp decrease and are not easily replaceable by domesticated hives,” he said. “If wild bees disappear, many wild plants might be in danger as well – of which flower-rich meadows and beautiful orchid species are just a few examples.”
Fifteen species of bumblebee types, which have an essential part in fertilizing peas, beans, peanuts and clover, and 14 types of cellophane bee types, famous for aiding tree pollination such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee unique to the European continent and the only species of this genus in European nations, is now evaluated as critically endangered – the scientific classification nearest to disappearance in the wild.
Butterflies that are solely present on mountain peaks are especially at risk to global warming as they need to move uphill as their living spaces become more heated but eventually exhaust available space. In the southern part of Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of species endemic to Europe (only found in Europe) threatened with extinction.
In the Mediterranean region, species such as the highly at-risk Karpathos grayling butterfly are endangered by intense wildfires and drought.
In the meantime, in the Arctic region, global heating is causing the timberline to shift northward by tens of metres each year, with scrub taking over wetlands and tundra. Higher temperatures also mean caribou can no more cross the ice to feed on Arctic grasslands and maintain them clear. Eight butterfly species are facing extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The greatest environment for all these pollinators is flower-rich grassland and that is vanishing rapidly across the European continent because of all these factors,” said Martin Warren. “The encouraging aspect is that so many citizens are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all member states have to turn around the decline in pollinating species by the year 2030, and they are going to have to begin taking action. There are land holders who are engaged. We hope they can obtain the encouragements that will help them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which won’t reduce agricultural output – and may enhance it – such as farmers creating bloom-filled edges around their cultivated areas.
the EU’s environment commissioner, described the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Urgent and collective action is needed to confront this risk. Along with member countries, the European Commission has implemented an EU-wide observation system for pollinating insects based on the EU nature restoration law, which will aid in following our advancement. Now, we need to concentrate on application and collaboration with member states to preserve our pollinators,” she said.
The release of the assessments on bees and butterflies follows the initial European-wide assessment of hoverflies, a further essential pollinator group. Published in 2022, it revealed that over one-third of all hoverfly species in European nations were at risk of extinction.
