The count of non-managed bee varieties in Europe confronting extinction has over doubled during the previous ten-year period, and the count of threatened butterfly species has nearly doubled.
This critical situation for essential pollinating species was revealed by scientific assessments for the red list of threatened species, which established that at least over 170 bee species out of over 1900 were threatened with extinction in European nations.
The total of butterfly types facing extinction in European nations has increased from thirty-seven to 65 since the earlier research, conducted 14 years ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
“Beyond their aesthetic appeal and cultural value, pollinators like bees along with butterflies are crucial elements for our physical condition, our food supplies and our economies – supporting the produce, vegetables and seeds that feed us,” said the IUCN’s director general. “The latest European red list evaluations reveal major obstacles, with threats increasing for butterfly species and vital non-managed bee species.”
The reasons of the swift recent drops are the ongoing harm or degradation of natural habitats caused by intensive agriculture and land abandonment, draining wetlands, excessive grazing by animals, and the application of chemical fertilisers and pesticides including neonicotinoid pesticides. The breaking up of pollinator-friendly habitat greatly increases the risk of extinctions at local level.
Climate change is also shown to be a major threat: Fifty-two percent of all at-risk butterfly species in European nations are imperilled by the climate emergency – roughly double the number as a ten years ago.
Nearly nine out of ten of flowering plants in the European continent require animal pollination, according to the wild bee assessment’s lead coordinator. “Unfortunately, native bee colonies are in drastic decline and cannot readily be substituted by managed colonies,” he said. “If wild bees vanish, many wild plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”
Fifteen species of bumblebees, which have an essential part in pollinating legumes like peas, beans, peanuts and clover, and 14 species of cellophane bees, famous for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee found only in the continent and the single type of this genus group in the European continent, is now classified as critically endangered – the research category nearest to dying out in natural habitats.
Butterfly species that are exclusively located on high-altitude areas are highly susceptible to global warming as they need to move uphill as their environments become more heated but in the end have no room left. In Spain’s southern region, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean area, varieties such as the severely threatened grayling of Karpathos are imperilled by severe drought and wildfires.
Meanwhile, in the Arctic Circle, climate change is leading to the tree line to advance northwards by many meters each year, with bushes encroaching on bog and tundra. Hotter climates also mean caribou can not anymore cross the frozen water to graze Arctic grasslands and maintain them clear. 8 butterfly varieties are at risk of extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The greatest environment for all these pollinating species is flower-rich grassland and that is disappearing very fast in Europe because of all these reasons,” remarked one of the lead coordinators of the butterflies assessment. “The good news is that so many people are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member states have to reverse the decline in pollinators by twenty-thirty, and they are going to have to begin taking action. There are land holders who are involved. Let’s hope they can get the motivations that will assist them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of measures for pollinators which will not decrease food production – and may enhance it – such as farmers creating margins rich in flowers around their cultivated areas.
EU commissioner for environment, described the conservation status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Immediate and joint measures is needed to address this danger. Along with participating nations, the Commission of the European Union has implemented an EU-wide observation system for pollinators based on the EU nature restoration regulation, which will help to track our advancement. Now, we need to prioritize execution and collaboration with member states to protect our pollinators,” she said.
The release of the evaluations of bees along with butterflies follows the initial Europe-wide assessment of hoverflies, another crucial pollinator group. Issued in twenty-twenty-two, it disclosed that over one-third of all hoverfly species in the European continent were facing extinction.
