The number of non-managed bee species in European nations confronting dying out has more than doubled over the past decade, and the number of at-risk butterfly types has nearly doubled.
This pressing issue for crucial pollinating insects was revealed by scientific studies for the IUCN red list, which found that at least over 170 bee varieties out of 1,928 were threatened with extinction in Europe.
The count of butterflies facing extinction in the European continent has grown from thirty-seven to sixty-five since the last study, carried out a decade and a half ago. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
Apart from their visual charm and cultural significance, pollinating species like bees along with butterflies are essential supports for our well-being, our food supplies and our financial structures – maintaining the fruits, vegetables and seeds that sustain us,” commented Grethel Aguilar. “The most recent assessments of the European red list reveal major obstacles, with risks growing for butterfly species and crucial wild bee types.”
The reasons of the swift recent drops are the continuing destruction or damage of living environments caused by agricultural intensification and abandoned land, draining of wetlands, overgrazing by livestock, and the application of fertilisers and pesticides including neonicotinoids. The fragmentation of pollinator-friendly habitat greatly increases the risk of disappearances in specific areas.
Global heating is also demonstrated to be a significant danger: Over half of all threatened butterflies in European nations are threatened by the climate change crisis – roughly twofold the amount as a decade ago.
Up to 90% of plants that flower in Europe rely on insect pollination, as per the wild bee assessment’s lead coordinator. “Regrettably, wild bee colonies are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If native bees die out, many wild plants might be in danger as well – of which flower-rich meadows and lovely orchid types are just a couple of instances.”
Fifteen species of bumblebee species, which perform a vital function in pollinating peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for aiding tree pollination such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species exclusive to the continent and the single type of this genus in European nations, is now evaluated as critically at risk – the research category most akin to dying out in natural habitats.
Butterfly species that are only found on mountain tops are particularly vulnerable to global heating as they need to move uphill as their environments become warmer but in the end have no room left. In the southern part of Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among more than 40% of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean area, species such as the severely threatened Karpathos grayling are imperilled by severe drought and wildfires.
Meanwhile, in the Arctic Circle, global heating is leading to the forest boundary to shift northward by many meters each year, with scrub taking over bog and tundra. Hotter climates also mean Arctic deer can not anymore cross the ice sheets to graze Arctic meadows and maintain them clear. Eight types of butterflies are at risk of extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The largest habitat for all these pollinating species is flower-rich grassland and that is declining quickly throughout the European continent because of all these elements,” said Martin Warren. “The encouraging aspect is that so many citizens are concerned now and there’s a lot more consciousness. Under the European Union nature restoration law, all member states have to halt the decrease in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are land holders who are involved. Let’s hope they can get the encouragements that will support them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of measures for pollinating species which won’t reduce agricultural output – and may enhance it – such as farmers establishing flower-rich margins around their fields.
EU commissioner for environment, portrayed the conservation status of native bees, butterflies and additional pollinators as “dire”.
“Prompt and unified steps is necessary to tackle this risk. Along with participating nations, the Commission of the European Union has established an European Union-wide tracking system for pollinators based on the EU nature restoration law, which will help to track our advancement. Now, we need to focus on implementation and cooperation with member countries to safeguard our pollinating species,” she said.
The issuance of the bee and butterfly assessments is subsequent to the first EU-wide evaluation of hoverflies, an additional crucial pollinator group. Published in 2022, it revealed that over one-third of all hoverfly types in the European continent were facing extinction.
