The number of wild bee varieties in the European continent facing extinction has more than doubled over the past decade, whereas the count of endangered butterfly types has nearly doubled.
This dire scenario for essential pollinating species was revealed by research studies for the IUCN red list, which found that at least one hundred seventy-two bee varieties out of over 1900 were at risk of extinction in the European continent.
The total of butterfly types threatened with extinction in European nations has risen from thirty-seven to sixty-five since the previous assessment, carried out 14 years ago. One species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
Apart from their beauty and cultural significance, pollinating insects like bees and butterfly species are essential supports for our well-being, our food supplies and our economies – sustaining the fruits, veggies and seeds that feed us,” said the IUCN director general. “The latest European red list assessments reveal major obstacles, with risks mounting for butterflies and vital non-managed bee varieties.”
The reasons of the swift recent drops are the persistent harm or degradation of living environments caused by agricultural intensification and abandoned land, wetland drainage, livestock overgrazing, and the utilization of pesticides and fertilisers including neonicotinoids. The division of environments suitable for pollinators greatly increases the danger of disappearances in specific areas.
Global warming is also revealed to be a significant danger: 52% of all endangered butterfly types in the European continent are imperilled by the climate emergency – approximately twice as many as a previous decade.
Nearly 90% of plants that flower in the European continent depend on animal pollination, as stated by the lead coordinator of the wild bee assessment. “Unfortunately, wild bee colonies are in sharp decrease and cannot readily be substituted by managed colonies,” he said. “If native bees die out, many non-cultivated plants might be threatened too – 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 legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee types, known for aiding tree pollination such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the mainland and the sole species of this biological genus in Europe, is now assessed as critically at risk – the scientific classification closest to disappearance in the wild.
Butterfly species that are solely present on mountain peaks are highly susceptible to global heating as they must ascend higher as their habitats become hotter but eventually run out of space. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue are among over forty percent of European endemics (only found in Europe) facing extinction.
In the Mediterranean area, types such as the critically endangered Karpathos grayling are imperilled by severe drought and wildfires.
Meanwhile, in the Far North, global warming is causing the timberline to shift northward by many meters each year, with scrub encroaching on marsh and tundra. Warmer conditions also mean caribou can no more cross the frozen water to feed on Arctic meadows and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this zone, including Freyja’s fritillary and the ringlet of the Arctic.
“The biggest habitat for all these pollinating insects is flower-rich grassland and that is disappearing very fast throughout 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 nature restoration legislation, all participating nations have to turn around the drop in pollinators by twenty-thirty, and they are going to have to begin taking action. There are property owners who are interested. Let’s hope they can get the incentives that will help them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of action for pollinating insects which will not decrease crop yields – and may enhance it – such as agricultural producers establishing bloom-filled edges around their cultivated areas.
the EU’s environment commissioner, characterized the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Prompt and unified steps is required to address this danger. Together with member states, the Commission of the European Union has implemented an EU-wide observation system for pollinators based on the EU nature restoration law, which will aid in following our progress. Now, we need to concentrate on application and collaboration with participating nations to preserve our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies follows the first European-wide assessment of hoverflies, another essential group of pollinators. Published in twenty-twenty-two, it disclosed that over one-third of all hoverfly varieties in European nations were facing extinction.
