The count of wild bee species in European nations facing extinction has more than doubled over the past decade, and the total of at-risk butterfly species has nearly doubled.
This pressing issue for essential pollinating species was revealed by scientific studies for the red list of threatened species, which established that at least one hundred seventy-two bee species out of nearly two thousand were at risk of extinction in European nations.
The total of butterfly species facing extinction in Europe has risen from 37 to over sixty since the last study, conducted 14 years ago. A single species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
“Beyond their aesthetic appeal and cultural value, pollinators like bees and butterfly species are crucial elements for our physical condition, our food systems and our economies – supporting the fruits, veggies and seeds that nourish us,” said Grethel Aguilar. “The newest European red list evaluations reveal major obstacles, with risks increasing for butterfly types and essential wild bee varieties.”
The factors of the rapid recent declines are the ongoing damage or destruction of living environments caused by agricultural intensification and land abandonment, draining of wetlands, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat substantially boosts the danger of extinctions at local level.
Global warming is also shown to be a significant danger: Fifty-two percent of all endangered butterflies in the European continent are threatened by the climate crisis – roughly twofold the amount as a decade ago.
As many as ninety percent of blooming plants in Europe rely on animal pollination, according to Dr Denis Michez. “Regrettably, wild bee populations are in drastic decline and are not easily replaceable by managed colonies,” he said. “If native bees vanish, many non-cultivated plants might be threatened too – of which flower-rich meadows and lovely orchid types are just a few examples.”
Fifteen types of bumblebees, which have an essential part in fertilizing legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type unique to the European continent and the only species of this biological genus in European nations, is now classified as critically endangered – the research category most akin to dying out in natural habitats.
Butterfly types that are exclusively located on mountain tops are particularly vulnerable to global heating as they need to move uphill as their environments become hotter but in the end exhaust available space. In Spain’s southern region, the Nevada grayling and the anomalous blue of Andalusia are among above 40 percent of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean, species such as the severely threatened grayling of Karpathos are threatened by severe dry conditions and fires.
At the same time, in the Arctic region, global heating is resulting in the tree line to advance northwards by tens of metres each year, with scrub encroaching on bog and tundra. Hotter climates also mean Arctic deer can no more cross the frozen water to feed on Arctic grasslands and keep them open. Eight types of butterflies are threatened with extinction in this region, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The biggest habitat for all these pollinating insects is flower-rich grassland and that is declining quickly across the European continent because of all these factors,” said Martin Warren. “The positive thing is that so many people are aware now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member states have to halt the decline in pollinating species by twenty-thirty, and they are going to have to start doing something. There are property owners who are engaged. We hope they can obtain the motivations that will support them on their way.”
As stated by the coordinator, there is “easy opportunities” in terms of measures for pollinators which will not lower food production – and might boost it – such as farmers developing bloom-filled edges around their farmland.
the EU’s environment commissioner, characterized the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Prompt and unified steps is needed to confront this threat. In collaboration with participating nations, the Commission of the European Union has implemented an European Union-wide monitoring system for pollinators based on the European Union nature restoration legislation, which will aid in following our advancement. Now, we need to concentrate on application and cooperation with member states to preserve our pollinating insects,” she said.
The publication of the evaluations of bees along with butterflies comes after the first Europe-wide evaluation of hoverflies, another crucial group of pollinators. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly types in Europe were at risk of extinction.
