The count of wild bee species in the European continent experiencing extinction has more than doubled over the past decade, whereas the number of threatened butterfly types has almost doubled.
This critical situation for crucial pollinating species was disclosed by research studies for the IUCN red list, which determined that at least over 170 bee species out of 1,928 were facing extinction in European nations.
The total of butterfly types threatened with extinction in Europe has grown from 37 to sixty-five since the last study, conducted over a decade past. 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 supplies and our economies – maintaining the fruits, veggies and seeds that sustain us,” stated Grethel Aguilar. “The newest European red list assessments reveal serious challenges, with risks growing for butterfly types and crucial non-managed bee varieties.”
The reasons of the rapid recent declines are the persistent destruction or damage of habitats caused by intensive agriculture and deserted farmland, draining wetlands, overgrazing by livestock, and the utilization of chemical fertilisers and pesticides including neonicotinoids. The division of pollinator-friendly habitat greatly increases the risk of extinctions at local level.
Climate change is also demonstrated to be a significant danger: Fifty-two percent of all threatened butterflies in European nations are imperilled by the climate crisis – about double the number as a previous decade.
Up to nine out of ten of plants that flower in Europe depend on animal pollination, as stated by the wild bee assessment’s lead coordinator. “Sadly, non-managed bee populations are in sharp decrease and cannot readily be substituted by managed bee colonies,” he said. “If native bees vanish, many native plants might be threatened too – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”
15 varieties of bumblebee species, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee types, known for aiding tree pollination such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the European continent and the sole species of this biological genus in Europe, is now evaluated as critically at risk – the scientific classification most akin to dying out in natural habitats.
Butterfly types that are solely present on high-altitude areas are especially at risk to climate change as they must ascend higher as their living spaces become warmer but eventually run out of space. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of types unique to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean region, varieties such as the highly at-risk grayling of Karpathos are imperilled by intense drought and wildfires.
Meanwhile, in the Arctic Circle, global warming is leading to the forest boundary to move north by tens of metres each year, with bushes encroaching on bog and tundra. Hotter climates also mean Arctic deer can not anymore cross the ice sheets to feed on northern grasslands and maintain them clear. 8 butterfly varieties are facing extinction in this area, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The largest habitat for all these pollinating species is bloom-filled grassy areas and that is declining quickly in Europe because of all these elements,” remarked one of the lead coordinators of the butterflies assessment. “The good news is that so many citizens are aware now and there’s a lot more understanding. Under the EU nature restoration legislation, all member countries have to reverse the decline in pollinating species by 2030, and they are going to have to start doing something. There are landowners who are involved. It is hoped they can get the incentives that will assist them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which will not lower crop yields – and could improve it – such as growers establishing margins rich in flowers around their farmland.
the EU’s environment commissioner, portrayed the protection status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Immediate and joint measures is necessary to tackle this threat. In collaboration with member countries, the European Commission has implemented an Europe-wide tracking system for pollinators based on the EU nature restoration regulation, which will aid in following our development. Now, we need to focus on execution and collaboration with member states to safeguard our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies comes after the pioneering EU-wide evaluation of hoverflies, a further essential pollinating insect category. Issued in twenty-twenty-two, it showed that 37% of all hoverfly species in the European continent were at risk of extinction.
