The number of native bee types in the European continent experiencing disappearance has more than doubled over the past decade, and the count of threatened butterfly has almost doubled.
This pressing issue for crucial pollinating species was unveiled by scientific assessments for the red list of threatened species, which found that at least over 170 bee types out of over 1900 were at risk of extinction in European nations.
The total of butterflies facing extinction in European nations has grown from 37 to 65 since the earlier research, performed over a decade past. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
“Beyond their visual charm and cultural significance, pollinating species like bees and butterflies are crucial elements for our physical condition, our food chains and our economic systems – maintaining the produce, vegetables and seeds that sustain us,” commented the IUCN director general. “The latest assessments of the European red list reveal serious challenges, with threats increasing for butterfly types and crucial native bee species.”
The reasons of the quick recent decreases are the ongoing destruction or damage of habitats caused by farming intensification and land abandonment, draining wetlands, excessive grazing by animals, and the utilization of chemical fertilisers and pesticides including neonicotinoids. The fragmentation of habitat friendly to pollinators greatly increases the danger of extinctions at local level.
Global heating is also revealed to be a significant danger: Over half of all endangered butterfly types in Europe are endangered by the climate emergency – roughly double the number as a ten years ago.
As many as nine out of ten of flowering plants in the European continent rely on insect pollination, as stated by the lead coordinator of the wild bee assessment. “Sadly, wild bee colonies are in drastic decline and are not easily replaceable by managed colonies,” he said. “If native bees disappear, many wild plants might be in danger as well – of which bloom-filled grasslands and attractive orchid varieties are just a couple of instances.”
Fifteen species of bumblebees, which play a crucial role in fertilizing crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, known for aiding tree pollination such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the sole species of this biological genus in Europe, is now assessed as critically endangered – the scientific category most akin to disappearance in the wild.
Butterfly species that are exclusively located on mountain tops are highly susceptible to global heating as they need to move uphill as their environments become more heated but eventually have no room left. In the southern part of Spain, the Nevada grayling and the anomalous blue of Andalusia are among over forty percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean region, varieties such as the highly at-risk Karpathos grayling butterfly are endangered by extreme wildfires and drought.
In the meantime, in the Arctic region, climate change is resulting in the forest boundary to advance northwards by dozens of meters each year, with underbrush invading marsh and tundra. Hotter climates also mean caribou can no more cross the ice to feed on Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are facing extinction in this area, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The largest living space for all these pollinators is bloom-filled grassy areas and that is declining quickly across European nations because of all these reasons,” remarked Martin Warren. “The encouraging aspect is that so many citizens care now and there’s a lot more awareness. Under the European Union nature restoration law, 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 land holders who are interested. Let’s hope they can get the encouragements that will help them on their way.”
According to the coordinator, there is “low-hanging fruit” in terms of action for pollinating insects which won’t reduce agricultural output – and could improve it – such as agricultural producers creating bloom-filled edges around their cultivated areas.
Jessika Roswall, described the preservation condition of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is needed to tackle this danger. Together with member countries, the European Commission has implemented an European Union-wide observation system for pollinating species based on the EU nature restoration regulation, which will aid in following our progress. Now, we need to prioritize application and cooperation with member states to protect our pollinating insects,” she said.
The release of the assessments on bees and butterflies comes after the initial EU-wide assessment of hoverflies, an additional vital group of pollinators. Published in twenty-twenty-two, it revealed that over one-third of all hoverfly types in European nations were facing extinction.
