The count of native bee species in the European continent experiencing disappearance has more than doubled in the last ten years, and the count of endangered butterfly species has nearly doubled.
This critical situation for crucial pollinating species was unveiled by research studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least 172 bee types out of nearly two thousand were facing extinction in Europe.
The count of butterflies at risk of extinction in Europe has increased from 37 to over sixty since the previous assessment, carried out over a decade past. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural value, pollinators like bees and butterflies are essential supports for our physical condition, our food chains and our financial structures – supporting the fruits, vegetables and seeds that sustain us,” said the IUCN director general. “The newest European red list assessments reveal significant difficulties, with risks mounting for butterflies and crucial native bee types.”
The reasons of the rapid recent declines are the persistent harm or degradation of living environments caused by intensive agriculture and abandoned land, draining wetlands, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoids. The division of environments suitable for pollinators significantly raises the danger of local extinctions.
Global warming is also demonstrated to be a primary risk: Over half of all threatened butterflies in Europe are endangered by the climate crisis – roughly twofold the amount as a previous decade.
Nearly nine out of ten of flowering plants in the European continent depend on insect pollination, according to Dr Denis Michez. “Sadly, wild bee populations are in severe drop and are not easily replaceable by managed colonies,” he said. “If non-managed bees die out, many wild plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a handful of illustrations.”
Fifteen types of bumblebee species, which have an essential part in fertilizing peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the only species of this biological genus in European nations, is now assessed as critically at risk – the scientific classification nearest to disappearance in the wild.
Butterfly species that are exclusively located on high-altitude areas are particularly vulnerable to climate change as they have to climb upward as their living spaces become hotter but eventually exhaust available space. In southern Spain, the Nevada grayling and the Andalusian anomalous blue are among above 40 percent of European endemics (only found in Europe) threatened with extinction.
In the Mediterranean region, varieties such as the highly at-risk Karpathos grayling are endangered by intense wildfires and drought.
Meanwhile, in the Arctic region, climate change is causing the timberline to move north by dozens of meters each year, with scrub invading wetlands and tundra. Warmer conditions also mean caribou can not anymore cross the ice sheets to browse Arctic meadows and maintain them clear. 8 butterfly varieties are at risk of extinction in this region, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The greatest living space for all these pollinating insects is grassland rich in flowers and that is disappearing very fast in Europe because of all these elements,” stated Martin Warren. “The good news is that so many people care now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all member states have to reverse the drop in pollinating species by 2030, and they are going to have to initiate measures. There are property owners who are involved. Let’s hope they can get the incentives that will help them on their way.”
As per the coordinator, there is “easy opportunities” in terms of action for pollinating insects which won’t reduce food production – and may enhance it – such as agricultural producers establishing flower-rich margins around their farmland.
Jessika Roswall, portrayed the preservation condition of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is needed to address this danger. Along with participating nations, the EU Commission has implemented an Europe-wide observation system for pollinating species based on the EU nature restoration law, which will aid in following our development. Now, we need to focus on implementation and partnership with member countries to safeguard our pollinating insects,” she said.
The publication of the assessments on bees and butterflies follows the pioneering European-wide assessment of hoverflies, a further crucial pollinator group. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly species in Europe were at risk of extinction.
