The count of wild bee types in European nations confronting extinction has more than doubled during the previous ten-year period, whereas the number of at-risk butterfly types has close to doubled.
This critical situation for essential pollinators was disclosed by research studies for the IUCN red list, which established that at least over 170 bee varieties out of nearly two thousand were facing extinction in European nations.
The count of butterfly types at risk of extinction in Europe has risen from over thirty-five to 65 since the previous assessment, performed 14 years ago. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their beauty and cultural importance, pollinating insects like bees along with butterflies are crucial elements for our health, our food supplies and our economic systems – sustaining the fruits, veggies and seeds that nourish us,” said the IUCN director general. “The newest European red list assessments reveal significant difficulties, with threats increasing for butterfly types and vital native bee types.”
The causes of the swift recent drops are the ongoing destruction or damage of habitats caused by agricultural intensification and land abandonment, wetland drainage, excessive grazing by animals, and the utilization of pesticides and fertilisers including neonicotinoid chemicals. The fragmentation of environments suitable for pollinators substantially boosts the danger of disappearances in specific areas.
Global warming is also revealed to be a major threat: Fifty-two percent of all threatened butterfly types in European nations are imperilled by the climate change crisis – approximately twice as many as a ten years ago.
Nearly nine out of ten of blooming plants in European nations depend on animal pollination, according to the wild bee assessment’s lead coordinator. “Sadly, non-managed bee groups are in drastic decline and are not easily replaceable by managed colonies,” he said. “If wild bees vanish, many non-cultivated plants might be at risk too – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”
Fifteen species of bumblebees, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee species, recognized for pollinating trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee exclusive to the continent and the single type of this genus in the European continent, is now classified as severely threatened – the scientific category closest to dying out in natural habitats.
Butterflies that are only found on high-altitude areas are highly susceptible to global heating as they must ascend higher as their habitats become hotter but ultimately run out of space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among over forty percent of species endemic to Europe (only found in Europe) facing extinction.
In the Mediterranean region, varieties such as the critically endangered Karpathos grayling butterfly are endangered by extreme dry conditions and fires.
Meanwhile, in the Far North, global warming is leading to the forest boundary to move north by tens of metres each year, with underbrush taking over bog and tundra. Hotter climates also mean reindeer can no more cross the frozen water to feed on Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The largest habitat for all these pollinating species is grassland rich in flowers and that is vanishing rapidly in European nations because of all these elements,” said Martin Warren. “The encouraging aspect is that so many citizens care now and there’s a lot more consciousness. Under the EU nature restoration legislation, all participating nations have to turn around the decline in pollinating species by 2030, and they are going to have to start doing something. There are landowners who are interested. Let’s hope they can receive the encouragements that will support them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of measures for pollinators which will not lower food production – and may enhance it – such as growers developing bloom-filled edges around their farmland.
EU commissioner for environment, portrayed the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Immediate and joint measures is needed to address this threat. Together with member countries, the European Commission has implemented an European Union-wide monitoring system for pollinators based on the EU nature restoration law, which will aid in following our advancement. Now, we need to concentrate on implementation and partnership with member countries to protect our pollinating insects,” she said.
The publication of the assessments on bees and butterflies follows the initial European-wide evaluation of hoverflies, another crucial pollinator group. Published in 2022, it showed that 37% of all hoverfly types in Europe were threatened with extinction.
