The total of wild bee types in Europe experiencing disappearance has more than doubled over the past decade, while the count of endangered butterfly types has nearly doubled.
This pressing issue for essential pollinators was disclosed by research studies for the IUCN red list, which determined that at least one hundred seventy-two bee types out of over 1900 were threatened with extinction in the European continent.
The count of butterfly types threatened with extinction in Europe has increased from 37 to 65 since the previous assessment, conducted 14 years ago. One type, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural value, pollinating species like bees and butterflies are crucial elements for our health, our food supplies and our economic systems – sustaining the fruits, vegetables and seeds that sustain us,” stated Grethel Aguilar. “The newest European red list evaluations reveal major obstacles, with risks growing for butterfly types and crucial wild bee species.”
The factors of the quick recent decreases are the continuing destruction or damage of habitats caused by agricultural intensification and abandoned land, wetland drainage, excessive grazing by animals, and the utilization of fertilisers and pesticides including neonicotinoids. The fragmentation of habitat friendly to pollinators greatly increases the threat of local extinctions.
Climate change is also revealed to be a primary risk: 52% of all at-risk butterfly types in Europe are threatened by the climate crisis – about twice as many as a previous decade.
Nearly ninety percent of plants that flower in European nations require pollination by animals, as stated by Dr Denis Michez. “Unfortunately, non-managed bee populations are in severe drop and cannot be easily replaced by managed bee colonies,” he said. “If native bees disappear, many non-cultivated plants might be threatened too – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
Fifteen species of bumblebee species, which play a crucial role in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for fertilizing trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the mainland and the sole species of this biological genus in the European continent, is now evaluated as severely threatened – the scientific classification nearest to disappearance in the wild.
Butterfly types that are solely present on high-altitude areas are especially at risk to global warming as they need to move uphill as their environments become hotter but ultimately run out of space. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among over forty percent of European endemics (solely present in Europe) facing extinction.
In the Mediterranean region, types such as the severely threatened Karpathos grayling butterfly are imperilled by severe dry conditions and fires.
In the meantime, in the Far North, global warming is resulting in the tree line to advance northwards by tens of metres each year, with underbrush encroaching on bog and tundra. Higher temperatures also mean Arctic deer can not anymore cross the ice sheets to browse northern grasslands and maintain them clear. Eight types of butterflies are facing extinction in this region, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The biggest environment for all these pollinating insects is bloom-filled grassy areas and that is declining quickly throughout European nations because of all these factors,” remarked a lead coordinator for the butterfly assessment. “The positive thing is that so many people care now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all participating nations have to halt the drop in pollinating insects by the year 2030, and they are going to have to initiate measures. There are landowners who are engaged. We hope they can obtain the incentives that will assist them on their way.”
As stated by the coordinator, there is “readily achievable actions” in terms of steps for pollinators which will not decrease food production – and could improve it – such as agricultural producers developing flower-rich margins around their farmland.
Jessika Roswall, portrayed the preservation condition of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is needed to confront this danger. In collaboration with member states, the Commission of the European Union has implemented an Europe-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will assist in monitoring our development. Now, we need to focus on implementation and partnership with member countries to preserve our pollinators,” she said.
The release of the evaluations of bees along with butterflies comes after the pioneering Europe-wide assessment of hoverflies, a further vital pollinating insect category. Released in 2022, it showed that over one-third of all hoverfly types in European nations were at risk of extinction.
