The number of native bee varieties in European nations experiencing dying out has over doubled over the past decade, whereas the total of endangered butterfly species has close to doubled.
This critical situation for vital pollinators was disclosed by research studies for the red list of threatened species, which established that at least over 170 bee varieties out of nearly two thousand were threatened with extinction in the European continent.
The count of butterflies facing extinction in European nations has risen from thirty-seven to 65 since the earlier research, carried out a decade and a half ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural value, pollinating species like bees and butterflies are essential supports for our well-being, our food systems and our economic systems – sustaining the fruits, veggies and seeds that feed us,” said Grethel Aguilar. “The latest European red list assessments reveal serious challenges, with dangers mounting for butterflies and crucial wild bee species.”
The factors of the quick recent decreases are the continuing damage or destruction of habitats caused by farming intensification and abandoned land, wetland drainage, overgrazing by livestock, and the use of pesticides and fertilisers including neonicotinoid chemicals. The division of habitat friendly to pollinators substantially boosts the risk of disappearances in specific areas.
Global heating is also shown to be a significant danger: Over half of all endangered butterfly species in the European continent are endangered by the climate crisis – roughly twice as many as a ten years ago.
Up to nine out of ten of plants that flower in Europe rely on animal pollination, as per the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee groups are in sharp decrease and cannot readily be substituted by domesticated hives,” he said. “If non-managed bees vanish, many wild plants might be at risk too – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebee species, which perform a vital function in pollinating legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species unique to the European continent and the only species of this genus in the European continent, is now evaluated as critically at risk – the scientific category nearest to dying out in natural habitats.
Butterfly types that are exclusively located on mountain peaks are particularly vulnerable to climate change as they must ascend higher as their habitats become more heated but eventually exhaust available space. In the southern part of Spain, the grayling of Nevada and the anomalous blue of Andalusia are among more than 40% of species endemic to Europe (only found in Europe) at risk of extinction.
In the Mediterranean region, types such as the highly at-risk grayling of Karpathos are imperilled by intense wildfires and drought.
In the meantime, in the Far North, global heating is resulting in the forest boundary to shift northward by tens of metres each year, with underbrush encroaching on marsh and tundra. Higher temperatures also mean reindeer can not anymore cross the ice sheets to graze Arctic grasslands and maintain them clear. Eight butterfly species are facing extinction in this area, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The largest environment for all these pollinators is bloom-filled grassy areas and that is declining quickly in the European continent because of all these reasons,” remarked Martin Warren. “The encouraging aspect is that so many citizens are aware now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member states have to reverse the decline in pollinators by twenty-thirty, and they are going to have to initiate measures. There are landowners who are involved. Let’s hope they can get the encouragements that will assist them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of measures for pollinators which will not lower food production – and could improve it – such as farmers developing flower-rich margins around their fields.
Jessika Roswall, portrayed the protection status of native bees, butterflies and additional pollinators as “dire”.
“Urgent and collective action is necessary to confront this danger. Along with participating nations, the European Commission has established an Europe-wide monitoring system for pollinating species based on the European Union nature restoration legislation, which will assist in monitoring our progress. Now, we need to concentrate on execution and cooperation with participating nations to protect our pollinators,” she said.
The issuance of the evaluations of bees along with butterflies comes after the initial EU-wide assessment of hoverflies, a further crucial pollinating insect category. Issued in 2022, it revealed that 37% of all hoverfly species in Europe were facing extinction.
