The total of non-managed bee species in European nations confronting dying out has over doubled in the last ten years, whereas the total of endangered butterfly types has close to doubled.
This dire scenario for vital pollinating species was disclosed by scientific studies for the red list of threatened species, which determined that at least one hundred seventy-two bee varieties out of nearly two thousand were at risk of extinction in European nations.
The number of butterfly species threatened with extinction in the European continent has risen from over thirty-five to over sixty since the last study, carried out 14 years ago. A single species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
In addition to their aesthetic appeal and cultural significance, pollinating species like bees and butterfly species are crucial elements for our physical condition, our food supplies and our economic systems – maintaining the produce, vegetables and seeds that nourish us,” said the IUCN’s director general. “The latest European red list evaluations reveal serious challenges, with risks increasing for butterflies and crucial wild bee species.”
The factors of the rapid recent declines are the continuing harm or degradation of natural habitats caused by agricultural intensification and land abandonment, draining wetlands, livestock overgrazing, and the application of chemical fertilisers and pesticides including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat substantially boosts the danger of local extinctions.
Global heating is also demonstrated to be a significant danger: 52% of all at-risk butterflies in the European continent are threatened by the climate crisis – approximately twice as many as a decade ago.
Up to nine out of ten of flowering plants in European nations rely on animal pollination, as stated by the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee populations are in sharp decrease and cannot be easily replaced by managed colonies,” he said. “If non-managed bees disappear, many wild plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a few examples.”
15 varieties of bumblebee species, which perform a vital function in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee species, known for aiding tree pollination such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the European continent and the single type of this genus group in European nations, is now evaluated as critically at risk – the scientific classification closest to dying out in natural habitats.
Butterfly types that are only found on mountain peaks are especially at risk to climate change as they need to move uphill as their environments become warmer but ultimately run out of space. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean, varieties such as the severely threatened grayling of Karpathos are imperilled by intense drought and wildfires.
At the same time, in the Arctic Circle, global heating is resulting in the tree line to shift northward by many meters each year, with bushes invading marsh and tundra. Hotter climates also mean caribou can no more cross the frozen water to graze Arctic meadows and keep them open. 8 butterfly varieties are at risk of extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The biggest living space for all these pollinating species is grassland rich in flowers and that is declining quickly throughout Europe because of all these elements,” stated Martin Warren. “The positive thing is that so many individuals care now and there’s a lot more awareness. Under the EU nature restoration legislation, all member states have to halt the drop in pollinating species by twenty-thirty, and they are going to have to begin taking action. There are property owners who are involved. It is hoped they can obtain 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 lower crop yields – and may enhance it – such as agricultural producers establishing bloom-filled edges around their cultivated areas.
the EU’s environment commissioner, portrayed the protection status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Urgent and collective action is required to address this danger. In collaboration with member states, the Commission of the European Union has established an Europe-wide monitoring system for pollinating insects based on the European Union nature restoration legislation, which will assist in monitoring our advancement. Now, we need to focus on execution and collaboration with member states to safeguard our pollinators,” she said.
The publication of the evaluations of bees along with butterflies follows the first Europe-wide evaluation of hoverflies, an additional vital pollinator group. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly species in the European continent were facing extinction.
