The count of non-managed bee varieties in Europe confronting dying out has more than doubled during the previous ten-year period, while the total of endangered butterfly has almost doubled.
This pressing issue for crucial pollinating species was disclosed by scientific studies for the IUCN red list, which established that at least 172 bee varieties out of nearly two thousand were at risk of extinction in European nations.
The count of butterfly types at risk of extinction in European nations has risen from over thirty-five to 65 since the last study, performed a decade and a half ago. A single 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 lifelines for our physical condition, our food systems and our economic systems – supporting the fruits, veggies and seeds that nourish us,” stated the IUCN director general. “The latest assessments of the European red list reveal serious challenges, with threats mounting for butterfly species and crucial native bee species.”
The causes of the quick recent decreases are the persistent destruction or damage of habitats caused by farming intensification and deserted farmland, draining wetlands, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of environments suitable for pollinators significantly raises the threat of disappearances in specific areas.
Global warming is also demonstrated to be a primary risk: Fifty-two percent of all at-risk butterfly species in Europe are endangered by the climate crisis – about twofold the amount as a previous decade.
Nearly ninety percent of blooming plants in Europe require insect pollination, according to Dr Denis Michez. “Unfortunately, non-managed bee colonies are in sharp decrease and cannot readily be substituted by domesticated hives,” he said. “If wild bees disappear, many wild plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a handful of illustrations.”
15 varieties of bumblebees, which perform a vital function in fertilizing legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, recognized for pollinating trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type unique to the mainland and the only species of this genus in Europe, is now classified as critically endangered – the scientific category closest to dying out in natural habitats.
Butterflies that are only found on high-altitude areas are highly susceptible to global warming as they need to move uphill as their habitats become more heated but in the end have no room left. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among over forty percent of species endemic to Europe (solely present in Europe) facing extinction.
In the Mediterranean area, species such as the critically endangered Karpathos grayling butterfly are endangered by extreme dry conditions and fires.
In the meantime, in the Arctic Circle, global heating is resulting in the tree line to move north by dozens of meters each year, with scrub taking over bog and tundra. Higher temperatures also mean caribou can no more cross the ice to browse Arctic grasslands and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this area, including Freyja’s fritillary and the ringlet of the Arctic.
“The largest living space for all these pollinators is grassland rich in flowers and that is vanishing rapidly across European nations because of all these factors,” said one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are aware now and there’s a lot more consciousness. Under the EU nature restoration legislation, all participating nations have to halt the decline in pollinators by the year 2030, and they are going to have to start doing something. There are land holders who are interested. Let’s hope they can obtain the incentives that will help them on their way.”
As per the coordinator, there is “easy opportunities” in terms of measures for pollinators which won’t reduce crop yields – and might boost it – such as farmers establishing flower-rich margins around their cultivated areas.
the EU’s environment commissioner, described the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Urgent and collective action is needed to tackle this risk. In collaboration with member states, the Commission of the European Union has established an Europe-wide tracking system for pollinators based on the EU nature restoration law, which will assist in monitoring our development. Now, we need to prioritize execution and cooperation with member countries to protect our pollinators,” she said.
The publication of the bee and butterfly assessments is subsequent to the pioneering European-wide study on hoverflies, an additional essential pollinating insect category. Published in 2022, it showed that 37% of all hoverfly species in Europe were threatened with extinction.
