The count of native bee types in the European continent experiencing extinction has more than doubled during the previous ten-year period, and the number of endangered butterfly has nearly doubled.
This pressing issue for essential pollinators was unveiled by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least one hundred seventy-two bee types out of over 1900 were at risk of extinction in Europe.
The count of butterflies at risk of extinction in Europe has grown from 37 to sixty-five since the last study, performed over a decade past. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
Apart from their visual charm and cultural importance, pollinators like bees along with butterflies are lifelines for our physical condition, our food supplies and our economic systems – supporting the produce, vegetables and seeds that feed us,” commented the IUCN director general. “The most recent European red list assessments reveal serious challenges, with risks increasing for butterflies and crucial native bee types.”
The reasons of the rapid recent declines are the persistent destruction or damage of living environments caused by agricultural intensification and abandoned land, wetland drainage, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoid pesticides. The division of environments suitable for pollinators greatly increases the danger of extinctions at local level.
Global heating is also demonstrated to be a primary risk: Over half of all endangered butterfly types in Europe are imperilled by the climate emergency – roughly twice as many as a decade ago.
As many as nine out of ten of plants that flower in Europe require animal pollination, as stated by Dr Denis Michez. “Unfortunately, wild bee colonies are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If non-managed bees die out, many non-cultivated plants might be at risk too – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
Fifteen species of bumblebees, which have an essential part in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for aiding tree pollination such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the mainland and the sole species of this genus in Europe, is now evaluated as critically at risk – the scientific category nearest to dying out in natural habitats.
Butterfly types that are exclusively located on high-altitude areas are highly susceptible to global heating as they must ascend higher as their habitats become more heated but eventually run out of space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among more than 40% of European endemics (only found in Europe) threatened with extinction.
In the Mediterranean, varieties such as the severely threatened Karpathos grayling are endangered by intense drought and wildfires.
At the same time, in the Arctic region, global heating is resulting in the timberline to advance northwards by tens of metres each year, with underbrush invading wetlands and tundra. Warmer conditions also mean reindeer can not anymore cross the ice to feed on Arctic grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this area, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The biggest environment for all these pollinators is grassland rich in flowers and that is disappearing very fast across Europe because of all these reasons,” remarked Martin Warren. “The positive thing is that so many citizens are concerned now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all participating nations have to reverse the drop in pollinating insects by the year 2030, and they are going to have to start doing something. There are landowners who are interested. Let’s hope they can get the motivations that will assist them on their way.”
As stated by Martin Warren, there is “easy opportunities” in terms of steps for pollinators which will not decrease agricultural output – and might boost it – such as growers developing bloom-filled edges around their fields.
Jessika Roswall, portrayed the conservation status of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is needed to address this threat. Along with participating nations, the Commission of the European Union has put in place an European Union-wide monitoring system for pollinating insects based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to concentrate on application and partnership with member states to safeguard our pollinating species,” she said.
The issuance of the bee and butterfly assessments follows the initial Europe-wide study on hoverflies, a further crucial pollinating insect category. Released in 2022, it revealed that thirty-seven percent of all hoverfly species in the European continent were threatened with extinction.
