Concerning Surge in At-Risk Non-Managed Bee Varieties Throughout the European Continent
The number of native bee types in the European continent experiencing extinction has more than doubled over the past decade, and the count of at-risk butterfly species has close to doubled.
This critical situation for crucial pollinating species was disclosed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least over 170 bee varieties out of 1,928 were at risk of extinction in European nations.
The number of butterflies threatened with extinction in the European continent has increased from thirty-seven to sixty-five since the previous assessment, carried out 14 years ago. A single species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural significance, pollinators like bees along with butterflies are crucial elements for our health, our food supplies and our economic systems – sustaining the fruits, veggies and seeds that feed us,” said the IUCN’s director general. “The newest assessments of the European red list reveal major obstacles, with risks mounting for butterfly types and crucial wild bee types.”
The factors of the rapid recent declines are the continuing destruction or damage of living environments caused by farming intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoids. The breaking up of habitat friendly to pollinators greatly increases the threat of extinctions at local level.
Climate change is also revealed to be a significant danger: 52% of all endangered butterflies in Europe are endangered by the climate change crisis – about double the number as a previous decade.
Nearly 90% of blooming plants in Europe rely on insect pollination, as stated by the lead coordinator of the wild bee assessment. “Sadly, wild bee colonies are in drastic decline and cannot readily be substituted by managed bee colonies,” he said. “If native 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 types of bumblebee types, which play a crucial role in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for fertilizing trees such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the continent and the single type of this genus group in the European continent, is now evaluated as critically at risk – the research category closest to disappearance in the wild.
Butterflies that are solely present on mountain tops are highly susceptible to global heating as they must ascend higher as their habitats become warmer but in the end have no room left. In Spain’s southern region, the Nevada grayling and the anomalous blue of Andalusia are among more than 40% of European endemics (only found in Europe) at risk of extinction.
In the Mediterranean area, species such as the severely threatened Karpathos grayling butterfly are endangered by extreme drought and wildfires.
Meanwhile, in the Arctic region, global heating is causing the forest boundary to shift northward by dozens of meters each year, with underbrush encroaching on marsh and tundra. Warmer conditions also mean reindeer can not anymore cross the ice sheets to browse northern grasslands and maintain them clear. 8 butterfly varieties are facing extinction in this area, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The largest habitat for all these pollinating insects is bloom-filled grassy areas and that is disappearing very fast in European nations because of all these elements,” 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 consciousness. Under the European Union nature restoration law, all member countries have to halt the drop in pollinating species by 2030, and they are going to have to initiate measures. There are landowners who are interested. Let’s hope they can receive the motivations that will support them on their way.”
As per the coordinator, there is “low-hanging fruit” in terms of steps for pollinating species which will not lower agricultural output – and could improve it – such as farmers developing margins rich in flowers around their farmland.
the EU’s environment commissioner, described the protection status of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Prompt and unified steps is needed to address this risk. Along with member states, the Commission of the European Union has implemented an EU-wide observation system for pollinators based on the EU nature restoration law, which will aid in following our progress. Now, we need to prioritize application and partnership with member states to preserve our pollinating insects,” she said.
The issuance of the assessments on bees and butterflies is subsequent to the pioneering Europe-wide assessment of hoverflies, an additional essential pollinator group. Issued in 2022, it revealed that over one-third of all hoverfly species in the European continent were threatened with extinction.
