The total of non-managed bee varieties in Europe experiencing extinction has over doubled during the previous ten-year period, whereas the number of endangered butterfly has almost doubled.
This critical situation for vital pollinating species was revealed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least one hundred seventy-two bee types out of nearly two thousand were at risk of extinction in the European continent.
The total of butterfly species at risk of extinction in European nations has risen from over thirty-five to over sixty since the previous assessment, conducted 14 years ago. One species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural significance, pollinating species like bees and butterfly species are lifelines for our health, our food supplies and our economies – maintaining the fruits, veggies and seeds that feed us,” said the IUCN director general. “The latest assessments of the European red list reveal serious challenges, with dangers growing for butterfly types and vital native bee varieties.”
The reasons of the swift recent drops are the persistent damage or destruction of living environments caused by agricultural intensification and land abandonment, wetland drainage, overgrazing by livestock, and the use of chemical fertilisers and pesticides including neonicotinoids. The breaking up of habitat friendly to pollinators substantially boosts the danger of disappearances in specific areas.
Global warming is also revealed to be a significant danger: Fifty-two percent of all threatened butterflies in the European continent are endangered by the climate emergency – roughly twofold the amount as a previous decade.
As many as ninety percent of flowering plants in the European continent require insect pollination, as per Dr Denis Michez. “Regrettably, non-managed bee groups are in severe drop and cannot readily be substituted by managed bee colonies,” he said. “If wild bees disappear, many non-cultivated plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a few examples.”
Fifteen types of bumblebee types, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, famous for fertilizing trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee unique to the continent and the single type of this genus group in the European continent, is now classified as critically endangered – the research category closest to dying out in natural habitats.
Butterflies that are only found on mountain tops are especially at risk to global heating as they must ascend higher as their living spaces become warmer but ultimately run out of space. In the southern part of Spain, the Nevada grayling 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, varieties such as the highly at-risk grayling of Karpathos are threatened by intense wildfires and drought.
At the same time, in the Far North, global warming is resulting in the tree line to move north by many meters each year, with scrub taking over wetlands and tundra. Hotter climates also mean caribou can no longer cross the ice sheets to graze Arctic grasslands and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The biggest living space for all these pollinators is flower-rich grassland and that is disappearing very fast across European nations because of all these factors,” stated a lead coordinator for the butterfly assessment. “The good news is that so many citizens are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all participating nations have to halt the drop in pollinating insects by 2030, and they are going to have to begin taking action. There are landowners who are interested. We hope they can obtain the encouragements that will support them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of steps for pollinating species which will not lower food production – and might boost it – such as agricultural producers creating margins rich in flowers around their fields.
Jessika Roswall, characterized the protection status of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Urgent and collective action is required to address this risk. Together with member states, the Commission of the European Union has established an European Union-wide tracking system for pollinating species based on the European Union nature restoration legislation, which will assist in monitoring our development. Now, we need to focus on application and cooperation with participating nations to safeguard our pollinating insects,” she said.
The publication of the bee and butterfly assessments comes after the initial European-wide evaluation of hoverflies, a further crucial pollinating insect category. Issued in twenty-twenty-two, it showed that over one-third of all hoverfly types in European nations were threatened with extinction.
