The count of native bee types in Europe experiencing dying out has more than doubled in the last ten years, and the total of threatened butterfly species has close to doubled.
This dire scenario for vital pollinators was disclosed by scientific studies for the red list of threatened species, which found that at least 172 bee varieties out of 1,928 were threatened with extinction in European nations.
The count of butterfly species at risk of extinction in the European continent has risen from over thirty-five to 65 since the previous assessment, conducted a decade and a half ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
“Beyond their aesthetic appeal and cultural significance, pollinators like bees along with butterflies are essential supports for our health, our food systems and our economic systems – sustaining the fruits, vegetables and seeds that sustain us,” said Grethel Aguilar. “The most recent European red list evaluations reveal major obstacles, with dangers growing for butterfly species and vital non-managed bee varieties.”
The reasons of the rapid recent declines are the persistent damage or destruction of habitats caused by farming intensification and land abandonment, draining wetlands, livestock overgrazing, and the use of chemical fertilisers and pesticides including neonicotinoids. The fragmentation of pollinator-friendly habitat substantially boosts the danger of extinctions at local level.
Global heating is also demonstrated to be a significant danger: Over half of all endangered butterflies in Europe are threatened by the climate change crisis – approximately twice as many as a previous decade.
Nearly nine out of ten of flowering plants in European nations depend on insect pollination, as per the wild bee assessment’s lead coordinator. “Unfortunately, native bee groups are in sharp decrease and cannot readily be substituted by domesticated hives,” he said. “If wild bees vanish, many non-cultivated plants might be at risk too – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen types of bumblebee types, which perform a vital function in fertilizing crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, recognized for aiding tree pollination such as willows along with red maples, are now classified 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 assessed as critically at risk – the scientific category most akin to disappearance in the wild.
Butterflies that are exclusively located on mountain peaks are especially at risk to global heating as they must ascend higher as their habitats become more heated but in the end run out of space. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue are among above 40 percent of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean region, types such as the severely threatened Karpathos grayling are threatened by intense dry conditions and fires.
Meanwhile, in the Arctic Circle, climate change is causing the timberline to advance northwards by dozens of meters each year, with bushes invading bog and tundra. Higher temperatures also mean reindeer can no more cross the frozen water to browse Arctic grasslands and maintain them clear. Eight types of butterflies are at risk of extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The biggest living space for all these pollinating insects is bloom-filled grassy areas and that is disappearing very fast in the European continent because of all these elements,” said a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many people are concerned now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all participating nations have to turn around the decline in pollinating species by 2030, and they are going to have to begin taking action. There are landowners who are involved. It is hoped they can obtain the incentives that will assist them on their way.”
As stated by Martin Warren, there is “easy opportunities” in terms of action for pollinators which won’t reduce agricultural output – and might boost it – such as agricultural producers establishing flower-rich margins around their fields.
Jessika Roswall, portrayed the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is necessary to tackle this risk. Along with member countries, the Commission of the European Union has implemented an EU-wide monitoring system for pollinating species based on the EU nature restoration law, which will help to track our development. Now, we need to prioritize application and partnership with member countries to safeguard our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies is subsequent to the first Europe-wide evaluation of hoverflies, an additional crucial group of pollinators. Published in 2022, it revealed that 37% of all hoverfly species in the European continent were at risk of extinction.
