The number of non-managed bee species in the European continent confronting disappearance has more than doubled over the past decade, and the count of at-risk butterfly types has almost doubled.
This critical situation for crucial pollinating species was revealed by scientific assessments for the IUCN red list, which established that at least over 170 bee types out of over 1900 were facing extinction in the European continent.
The number of butterfly species at risk of extinction in Europe has increased from thirty-seven to sixty-five since the earlier research, conducted a decade and a half ago. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
“Beyond their aesthetic appeal and cultural value, pollinating species like bees and butterflies are crucial elements for our health, our food chains and our economies – sustaining the fruits, veggies and seeds that sustain us,” stated the IUCN director general. “The latest European red list assessments reveal serious challenges, with dangers mounting for butterflies and vital wild bee types.”
The factors of the swift recent drops are the ongoing harm or degradation of habitats caused by farming intensification and land abandonment, draining wetlands, excessive grazing by animals, and the use of fertilisers and pesticides including neonicotinoid pesticides. The breaking up of habitat friendly to pollinators significantly raises the threat of local extinctions.
Climate change is also shown to be a primary risk: Fifty-two percent of all threatened butterfly types in European nations are imperilled by the climate crisis – about double the number as a ten years ago.
Up to ninety percent of plants that flower in European nations require insect pollination, as stated by the wild bee assessment’s lead coordinator. “Unfortunately, native bee groups are in drastic decline and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees vanish, many wild plants might be in danger as well – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”
Fifteen species of bumblebee species, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee species, recognized for pollinating trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the mainland and the single type of this biological genus in the European continent, is now assessed as critically endangered – the scientific classification nearest to dying out in natural habitats.
Butterflies that are solely present on mountain tops are particularly vulnerable to global heating as they need to move uphill as their environments become more heated but in the end exhaust available space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean, species such as the highly at-risk grayling of Karpathos are imperilled by severe drought and wildfires.
At the same time, in the Far North, global heating is causing the tree line to move north by dozens of meters each year, with bushes invading wetlands and tundra. Warmer conditions also mean caribou can no more cross the frozen water to feed on northern grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this area, including Freyja’s fritillary and the ringlet of the Arctic.
“The biggest habitat for all these pollinators is bloom-filled grassy areas and that is disappearing very fast throughout Europe because of all these factors,” remarked Martin Warren. “The positive thing is that so many citizens are aware now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to turn around the decrease in pollinating species by twenty-thirty, 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 support them on their way.”
As stated by Warren, there is “easy opportunities” in terms of measures for pollinating insects which will not decrease agricultural output – and might boost it – such as growers developing bloom-filled edges around their fields.
the EU’s environment commissioner, described the conservation status of wild bees, butterflies and other pollinators as “dire”.
“Immediate and joint measures is necessary to tackle this danger. Together with member countries, the European Commission has implemented an Europe-wide tracking system for pollinators based on the EU nature restoration law, which will help to track our development. Now, we need to focus on execution and partnership with member states to preserve our pollinating insects,” she said.
The release of the assessments on bees and butterflies follows the pioneering Europe-wide assessment of hoverflies, a further crucial pollinator group. Released in twenty-twenty-two, it showed that thirty-seven percent of all hoverfly types in European nations were facing extinction.
