The number of non-managed bee species in European nations facing disappearance has increased twofold over the past decade, while the count of endangered butterfly types has nearly doubled.
This critical situation for crucial pollinating insects was revealed by research studies for the IUCN red list, which determined that at least one hundred seventy-two bee varieties out of 1,928 were at risk of extinction in the European continent.
The number of butterfly species facing extinction in the European continent has increased from over thirty-five to over sixty since the earlier research, conducted 14 years ago. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
In addition to their aesthetic appeal and cultural importance, pollinating species like bees and butterfly species are crucial elements for our physical condition, our food chains and our economies – supporting the fruits, veggies and seeds that feed us,” stated Grethel Aguilar. “The newest European red list evaluations reveal serious challenges, with threats increasing for butterfly species and essential wild bee species.”
The factors of the quick recent decreases are the persistent harm or degradation of living environments caused by agricultural intensification and deserted farmland, wetland drainage, livestock overgrazing, and the use of fertilisers and pesticides including neonicotinoids. The fragmentation of pollinator-friendly habitat significantly raises the danger of local extinctions.
Global heating is also shown to be a major threat: 52% of all endangered butterflies in the European continent are threatened by the climate emergency – approximately double the number as a ten years ago.
Nearly 90% of blooming plants in Europe require animal pollination, as stated by the lead coordinator of the wild bee assessment. “Unfortunately, non-managed bee populations are in severe drop and cannot be easily replaced by managed colonies,” he said. “If wild bees disappear, many wild plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a handful of illustrations.”
Fifteen types of bumblebee types, which play a crucial role in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee species, recognized for aiding tree pollination such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the European continent and the sole species of this genus in European nations, is now evaluated as critically endangered – the scientific category most akin to disappearance in the wild.
Butterfly types that are solely present on mountain tops are particularly vulnerable to global heating as they need to move uphill as their environments become warmer but in the end run out of space. In the southern part of Spain, the grayling of Nevada and the anomalous blue of Andalusia are among over forty percent of European endemics (exclusive to Europe) at risk of extinction.
In the Mediterranean, types such as the severely threatened Karpathos grayling are imperilled by severe dry conditions and fires.
In the meantime, in the Far North, climate change is leading to the forest boundary to move north by dozens of meters each year, with underbrush taking over marsh and tundra. Hotter climates also mean caribou can not anymore cross the frozen water to feed on Arctic grasslands and keep them open. Eight butterfly species are facing extinction in this zone, including the fritillary of Freyja and the Arctic ringlet.
“The greatest environment for all these pollinating species is flower-rich grassland and that is disappearing very fast throughout Europe because of all these reasons,” remarked a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many individuals care now and there’s a lot more awareness. Under the European Union nature restoration law, all member countries have to turn around the drop in pollinators by 2030, and they are going to have to begin taking action. There are land holders who are engaged. It is hoped they can get the incentives that will assist them on their way.”
As stated by the coordinator, there is “easy opportunities” in terms of steps for pollinating species which won’t reduce food production – and might boost it – such as agricultural producers creating bloom-filled edges around their cultivated areas.
Jessika Roswall, characterized the conservation status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Immediate and joint measures is required to tackle this risk. In collaboration with participating nations, the Commission of the European Union has implemented an EU-wide monitoring system for pollinating insects based on the EU nature restoration law, which will aid in following our progress. Now, we need to focus on implementation and cooperation with member states to safeguard our pollinators,” she said.
The publication of the bee and butterfly assessments is subsequent to the pioneering Europe-wide assessment of hoverflies, an additional essential pollinating insect category. Released in twenty-twenty-two, it showed that over one-third of all hoverfly types in the European continent were facing extinction.
