The total of non-managed bee varieties in Europe experiencing extinction has more than doubled during the previous ten-year period, whereas the count of endangered butterfly types has nearly doubled.
This pressing issue for vital pollinating species was disclosed by scientific studies for the red list of threatened species, which found that at least 172 bee varieties out of nearly two thousand were threatened with extinction in Europe.
The number of butterfly types at risk of extinction in European nations has risen from 37 to 65 since the last study, carried out 14 years ago. One species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
In addition to their aesthetic appeal and cultural significance, pollinators like bees along with butterflies are essential supports for our well-being, our food systems and our economies – sustaining the produce, vegetables and seeds that nourish us,” stated the IUCN’s director general. “The most recent European red list evaluations reveal major obstacles, with risks mounting for butterfly types and crucial wild bee types.”
The reasons of the quick recent decreases are the ongoing harm or degradation of natural habitats caused by farming intensification and land abandonment, wetland drainage, overgrazing by livestock, and the use of fertilisers and pesticides including neonicotinoid pesticides. The division of environments suitable for pollinators greatly increases the danger of extinctions at local level.
Climate change is also demonstrated to be a primary risk: Over half of all at-risk butterfly species in the European continent are imperilled by the climate crisis – about twofold the amount as a ten years ago.
As many as 90% of flowering plants in European nations require insect pollination, according to Dr Denis Michez. “Unfortunately, non-managed bee colonies are in sharp decrease and are not easily replaceable by managed colonies,” he said. “If wild bees die out, many native plants might be threatened too – of which meadows rich in flowers and attractive orchid varieties are just a handful of illustrations.”
15 varieties of bumblebee types, which perform a vital function in fertilizing legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, known for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the sole species of this genus group in European nations, is now assessed as critically at risk – the scientific category most akin to dying out in natural habitats.
Butterfly species that are only found on mountain tops are particularly vulnerable to global warming as they have to climb upward as their living spaces become hotter but eventually have no room left. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue are among above 40 percent of European endemics (only found in Europe) at risk of extinction.
In the Mediterranean, species such as the highly at-risk grayling of Karpathos are endangered by intense wildfires and drought.
At the same time, in the Far North, global warming is leading to the tree line to move north by dozens of meters each year, with underbrush encroaching on marsh and tundra. Higher temperatures also mean Arctic deer can not anymore cross the ice to graze Arctic grasslands and prevent them from overgrowing. Eight types of butterflies are at risk of extinction in this area, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The largest living space for all these pollinating species is grassland rich in flowers and that is vanishing rapidly across the European continent because of all these reasons,” stated one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many people are aware now and there’s a lot more understanding. Under the EU nature restoration legislation, all member countries have to halt the decline in pollinating species by twenty-thirty, and they are going to have to initiate measures. There are land holders who are engaged. It is hoped they can receive the motivations that will assist them on their way.”
According to Martin Warren, 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 developing margins rich in flowers around their farmland.
the EU’s environment commissioner, characterized the conservation status of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is needed to address this danger. In collaboration with member states, the EU Commission has put in place an EU-wide tracking system for pollinating species based on the EU nature restoration law, which will aid in following our advancement. Now, we need to concentrate on application and collaboration with member countries to safeguard our pollinating species,” she said.
The release of the evaluations of bees along with butterflies comes after the pioneering European-wide assessment of hoverflies, an additional essential pollinator group. Issued in 2022, it revealed that thirty-seven percent of all hoverfly species in Europe were at risk of extinction.
