Concerning Surge in Threatened Non-Managed Bee Varieties Across European Nations

The total of native bee types in European nations facing dying out has increased twofold during the previous ten-year period, and the count of at-risk butterfly has close to doubled.

This critical situation for essential pollinators was disclosed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which found that at least 172 bee types out of nearly two thousand were threatened with extinction in European nations.

The number of butterfly types at risk of extinction in the European continent has grown from over thirty-five to over sixty since the previous assessment, conducted 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.

“Beyond their visual charm and cultural value, pollinating species like bees along with butterflies are essential supports for our well-being, our food supplies and our economies – supporting the fruits, veggies and seeds that sustain us,” commented the IUCN’s director general. “The newest European red list evaluations reveal serious challenges, with dangers growing for butterflies and essential wild bee species.”

The reasons of the quick recent decreases are the persistent damage or destruction of habitats caused by intensive agriculture and abandoned land, wetland drainage, excessive grazing by animals, and the use of chemical fertilisers and pesticides including neonicotinoids. The breaking up of habitat friendly to pollinators greatly increases the risk of disappearances in specific areas.

Global heating is also demonstrated to be a primary risk: Fifty-two percent of all endangered butterfly species in European nations are threatened by the climate change crisis – approximately twice as many as a decade ago.

Nearly nine out of ten of blooming plants in Europe depend on insect pollination, as per Dr Denis Michez. “Unfortunately, wild bee populations are in severe drop and are not easily replaceable by managed bee colonies,” he said. “If native bees disappear, many wild plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a couple of instances.”

15 varieties of bumblebees, which play a crucial role in fertilizing peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, known for fertilizing trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the European continent and the only species of this genus in the European continent, is now evaluated as severely threatened – the research category most akin to disappearance in the wild.

Butterfly types that are only found on mountain peaks are particularly vulnerable to global warming as they need to move uphill as their living spaces become more heated but eventually exhaust available space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among over forty percent of types unique to Europe (exclusive to Europe) facing extinction.

In the Mediterranean, species such as the critically endangered Karpathos grayling are threatened by severe drought and wildfires.

Meanwhile, in the Far North, global warming is leading to the tree line to shift northward by dozens of meters each year, with scrub encroaching on wetlands and tundra. Hotter climates also mean Arctic deer can no longer cross the frozen water to browse Arctic grasslands and prevent them from overgrowing. 8 butterfly varieties are at risk of extinction in this zone, including Freyja’s fritillary and the ringlet of the Arctic.

“The biggest habitat for all these pollinating species is grassland rich in flowers and that is disappearing very fast throughout the European continent because of all these factors,” stated one of the lead coordinators of the butterflies assessment. “The positive thing is that so many people care now and there’s a lot more consciousness. Under the European Union nature restoration law, all participating nations have to halt the decline in pollinating species by twenty-thirty, and they are going to have to begin taking action. There are property owners who are involved. We hope they can get the encouragements that will support them on their way.”

As per Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which won’t reduce food production – and might boost it – such as farmers creating margins rich in flowers around their fields.

Jessika Roswall, portrayed the conservation status of non-managed bees, butterfly species and other pollinating insects as “dire”.

“Prompt and unified steps is required to confront this danger. Along with member states, the European Commission has implemented an EU-wide monitoring system for pollinators based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to focus on application and cooperation with participating nations to protect our pollinating species,” she said.

The issuance of the bee and butterfly assessments is subsequent to the first Europe-wide assessment of hoverflies, an additional vital group of pollinators. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly species in European nations were threatened with extinction.
