The count of native bee varieties in Europe experiencing disappearance has over doubled in the last ten years, and the count of threatened butterfly has close to doubled.
This pressing issue for vital pollinating insects was unveiled by scientific studies for the IUCN red list, which determined that at least over 170 bee types out of over 1900 were at risk of extinction in Europe.
The number of butterfly types threatened with extinction in European nations has increased from thirty-seven to sixty-five since the last study, carried out a decade and a half ago. One type, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
“Beyond their aesthetic appeal and cultural value, pollinators like bees and butterfly species are lifelines for our health, our food systems and our economies – supporting the produce, vegetables and seeds that sustain us,” stated Grethel Aguilar. “The latest European red list evaluations reveal significant difficulties, with risks mounting for butterfly types and crucial non-managed bee types.”
The causes of the swift recent drops are the ongoing destruction or damage of natural habitats caused by agricultural intensification and deserted farmland, wetland drainage, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat significantly raises the danger of local extinctions.
Climate change is also revealed to be a major threat: Over half of all at-risk butterfly types in Europe are threatened by the climate crisis – about double the number as a ten years ago.
Up to 90% of plants that flower in European nations require insect pollination, as stated by Dr Denis Michez. “Regrettably, wild bee colonies are in drastic decline and cannot readily be substituted by managed bee colonies,” he said. “If native bees die out, many native plants might be in danger as well – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
15 varieties of bumblebees, which have an essential part in pollinating legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, known for aiding tree pollination such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type exclusive to the mainland and the only species of this genus group in European nations, is now assessed as severely threatened – the scientific classification closest to dying out in natural habitats.
Butterfly types that are only found on mountain tops are particularly vulnerable to climate change as they need to move uphill as their environments become more heated but eventually run out of space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue butterfly are among above 40 percent of species endemic to Europe (only found in Europe) threatened with extinction.
In the Mediterranean area, types such as the critically endangered grayling of Karpathos are imperilled by intense wildfires and drought.
Meanwhile, in the Far North, global warming is resulting in the forest boundary to shift northward by dozens of meters each year, with scrub invading marsh and tundra. Higher temperatures also mean Arctic deer can not anymore cross the ice sheets to feed on Arctic grasslands and keep them open. 8 butterfly varieties are facing extinction in this zone, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The greatest environment for all these pollinating species is bloom-filled grassy areas and that is declining quickly in European nations because of all these elements,” remarked Martin Warren. “The positive thing is that so many citizens are aware now and there’s a lot more awareness. Under the European Union nature restoration law, all member states have to turn around the drop in pollinating species by the year 2030, and they are going to have to initiate measures. There are property owners who are involved. We hope they can obtain the encouragements that will assist them on their way.”
According to Martin Warren, there is “easy opportunities” in terms of steps for pollinating insects which will not lower agricultural output – and may enhance it – such as growers creating flower-rich margins around their farmland.
the EU’s environment commissioner, portrayed the conservation status of native bees, butterflies and additional pollinators as “severe”.
“Immediate and joint measures is required to address this risk. In collaboration with member countries, the EU Commission has put in place an European Union-wide monitoring system for pollinating insects based on the EU nature restoration law, which will help to track our progress. Now, we need to focus on execution and collaboration with participating nations to safeguard our pollinators,” she said.
The release of the evaluations of bees along with butterflies comes after the first EU-wide evaluation of hoverflies, an additional essential pollinating insect category. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly species in the European continent were threatened with extinction.
