Worrying Increase in At-Risk Native Bee Varieties In Europe

The number of native bee varieties in the European continent experiencing disappearance has more than doubled during the previous ten-year period, whereas the number of endangered butterfly species has nearly doubled.

This dire scenario for crucial pollinators was disclosed by research studies for the red list of threatened species, which established that at least one hundred seventy-two bee species out of over 1900 were at risk of extinction in Europe.

The total of butterflies facing extinction in European nations has risen from over thirty-five to sixty-five since the earlier research, carried out over a decade past. A single species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.

Apart from their aesthetic appeal and cultural significance, pollinating insects like bees along with butterflies are crucial elements for our well-being, our food supplies and our economies – supporting the fruits, veggies and seeds that nourish us,” commented the IUCN director general. “The most recent European red list assessments reveal significant difficulties, with dangers increasing for butterflies and crucial non-managed bee varieties.”

The reasons of the quick recent decreases are the continuing destruction or damage of habitats caused by intensive agriculture and abandoned land, wetland drainage, overgrazing by livestock, and the application of fertilisers and pesticides including neonicotinoid pesticides. The division of habitat friendly to pollinators greatly increases the threat of disappearances in specific areas.

Global heating is also demonstrated to be a primary risk: Over half of all at-risk butterfly species in European nations are threatened by the climate change crisis – about twofold the amount as a ten years ago.

Up to 90% of blooming plants in European nations depend on insect pollination, according to the wild bee assessment’s lead coordinator. “Unfortunately, non-managed bee colonies are in severe drop and cannot be easily replaced by managed colonies,” he said. “If non-managed bees disappear, many wild plants might be in danger as well – of which bloom-filled grasslands and lovely orchid types are just a handful of illustrations.”

Fifteen species of bumblebee types, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and 14 species of cellophane bee types, recognized for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the mainland and the single type of this biological genus in Europe, is now classified as severely threatened – the research category nearest to dying out in natural habitats.

Butterfly types that are solely present on high-altitude areas are particularly vulnerable to global warming as they must ascend higher as their environments become more heated but ultimately run out of space. In Spain’s southern region, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among over forty percent of types unique to Europe (exclusive to Europe) facing extinction.

In the Mediterranean region, species such as the critically endangered grayling of Karpathos are imperilled by extreme wildfires and drought.

In the meantime, in the Far North, global warming is leading to the tree line to move north by tens of metres each year, with bushes encroaching on bog and tundra. Hotter climates also mean caribou can no longer cross the ice sheets to browse northern grasslands and keep them open. 8 butterfly varieties are at risk of extinction in this area, including Freyja’s fritillary butterfly and the ringlet of the Arctic.

“The biggest environment for all these pollinating insects is bloom-filled grassy areas and that is vanishing rapidly in European nations because of all these reasons,” stated Martin Warren. “The encouraging aspect is that so many people are aware now and there’s a lot more consciousness. Under the EU nature restoration legislation, all participating nations have to reverse the decline in pollinating species by twenty-thirty, and they are going to have to start doing something. There are landowners who are engaged. We hope they can receive the encouragements that will help them on their way.”

According to the coordinator, there is “low-hanging fruit” in terms of steps for pollinators which won’t reduce crop yields – and might boost it – such as agricultural producers establishing margins rich in flowers around their fields.

the EU’s environment commissioner, characterized the protection status of wild bees, butterflies and other pollinators as “severe”.

“Prompt and unified steps is required to confront this risk. In collaboration with member states, the EU Commission has implemented an European Union-wide tracking system for pollinating insects based on the EU nature restoration regulation, which will aid in following our development. Now, we need to concentrate on application and partnership with member countries to preserve our pollinators,” she said.

The issuance of the assessments on bees and butterflies is subsequent to the initial Europe-wide assessment of hoverflies, another crucial group of pollinators. Published in 2022, it revealed that 37% of all hoverfly varieties in the European continent were facing extinction.
