Alarming Increase in Endangered Wild Bee Varieties In European Nations
The total of native bee varieties in the European continent experiencing extinction has over doubled during the previous ten-year period, whereas the number of threatened butterfly has nearly doubled.
This pressing issue for crucial pollinating insects was unveiled by scientific studies for the red list of threatened species, which found that at least over 170 bee species out of nearly two thousand were threatened with extinction in Europe.
The count of butterflies at risk of extinction in Europe has increased from thirty-seven to over sixty since the last study, performed over a decade past. A single species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural significance, pollinating species like bees and butterfly species are essential supports for our physical condition, our food systems and our economies – sustaining the fruits, veggies and seeds that feed us,” said the IUCN’s director general. “The newest assessments of the European red list reveal significant difficulties, with dangers increasing for butterfly types and essential wild bee species.”
The causes of the rapid recent declines are the ongoing damage or destruction of habitats caused by agricultural intensification and land abandonment, draining wetlands, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoids. The division of habitat friendly to pollinators substantially boosts the risk of extinctions at local level.
Global warming is also revealed to be a major threat: 52% of all threatened butterfly types in Europe are threatened by the climate change crisis – about twice as many as a decade ago.
Up to ninety percent of blooming plants in Europe depend on animal pollination, as per the lead coordinator of the wild bee assessment. “Sadly, non-managed bee groups are in severe drop and cannot be easily replaced by managed bee colonies,” he said. “If non-managed bees die out, many native plants might be at risk too – of which meadows rich in flowers and lovely orchid types are just a couple of instances.”
Fifteen species of bumblebee species, which perform a vital function in fertilizing crops such as peas, beans, peanuts and clover, and 14 species of cellophane bees, recognized for pollinating trees such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the continent and the sole species of this genus in Europe, is now assessed as critically at risk – the scientific category nearest to extinction in the wild.
Butterfly species that are only found on mountain tops are particularly vulnerable to climate change as they need to move uphill as their environments become hotter but ultimately have no room left. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among above 40 percent of types unique to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean, species such as the critically endangered grayling of Karpathos are endangered by severe wildfires and drought.
In the meantime, in the Arctic region, climate change is resulting in the forest boundary to shift northward by tens of metres each year, with underbrush invading bog and tundra. Warmer conditions also mean Arctic deer can no longer cross the ice sheets to browse Arctic meadows and keep them open. 8 butterfly varieties are threatened with extinction in this area, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The largest living space for all these pollinators is flower-rich grassland and that is declining quickly in the European continent because of all these factors,” said a lead coordinator for the butterfly assessment. “The good news is that so many individuals are aware now and there’s a lot more awareness. Under the European Union nature restoration law, all member states have to halt the decline in pollinating species by 2030, and they are going to have to initiate measures. There are land holders who are engaged. We hope they can obtain the incentives that will support them on their way.”
As stated by Warren, there is “low-hanging fruit” in terms of steps for pollinating species which will not lower agricultural output – and could improve it – such as agricultural producers establishing margins rich in flowers around their fields.
the EU’s environment commissioner, portrayed the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Prompt and unified steps is required to address this risk. In collaboration with member countries, the Commission of the European Union has established an European Union-wide observation system for pollinating insects based on the EU nature restoration law, which will help to track our development. Now, we need to focus on application and cooperation with member states to protect our pollinating species,” she said.
The issuance of the bee and butterfly assessments follows the pioneering Europe-wide study on hoverflies, a further vital pollinating insect category. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly types in Europe were threatened with extinction.
