Worrying Surge in Endangered Non-Managed Bee Varieties In European Nations

The count of wild bee species in Europe confronting dying out has more than doubled during the previous ten-year period, while the count of endangered butterfly species has nearly doubled.

This dire scenario for crucial pollinating insects was revealed by scientific assessments for the IUCN red list, which determined that at least one hundred seventy-two bee varieties out of nearly two thousand were threatened with extinction in Europe.

The total of butterflies threatened with extinction in the European continent has increased from thirty-seven to 65 since the last study, carried out over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.

In addition to their aesthetic appeal and cultural value, pollinating species like bees and butterflies are lifelines for our health, our food chains and our economies – maintaining the fruits, veggies and seeds that feed us,” commented the IUCN’s director general. “The most recent European red list assessments reveal serious challenges, with threats mounting for butterfly species and vital wild bee types.”

The causes of the rapid recent declines are the persistent harm or degradation of living environments caused by agricultural intensification and deserted farmland, draining of wetlands, excessive grazing by animals, and the application of chemical fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of environments suitable for pollinators greatly increases the danger of disappearances in specific areas.

Global warming is also revealed to be a significant danger: Fifty-two percent of all endangered butterfly species in European nations are imperilled by the climate emergency – about twice as many as a decade ago.

As many as 90% of flowering plants in Europe rely on pollination by animals, as stated by Dr Denis Michez. “Regrettably, native bee groups are in severe drop and cannot readily be substituted by managed colonies,” he said. “If wild bees disappear, many non-cultivated plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a couple of instances.”

15 varieties of bumblebee species, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, recognized for pollinating trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the single type of this genus in Europe, is now classified as severely threatened – the scientific category nearest to dying out in natural habitats.

Butterflies that are exclusively located on mountain tops are particularly vulnerable to global warming as they need to move uphill as their living spaces become warmer but ultimately have no room left. In the southern part of Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of types unique to Europe (only found in Europe) threatened with extinction.

In the Mediterranean, types such as the highly at-risk Karpathos grayling are imperilled by intense dry conditions and fires.

Meanwhile, in the Arctic Circle, global heating is leading to the timberline to move north by many meters each year, with bushes encroaching on bog and tundra. Higher temperatures also mean Arctic deer can not anymore cross the ice sheets to browse Arctic grasslands and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.

“The largest environment for all these pollinators is flower-rich grassland and that is disappearing very fast across European nations because of all these reasons,” stated Martin Warren. “The good news is that so many people are aware now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to halt the decrease in pollinating species by the year 2030, and they are going to have to begin taking action. There are property owners who are involved. We hope they can receive the incentives that will support them on their way.”

As per Warren, there is “easy opportunities” in terms of action for pollinating species which will not decrease crop yields – and might boost it – such as growers developing flower-rich margins around their farmland.

EU commissioner for environment, portrayed the preservation condition of non-managed bees, butterfly species and other pollinating insects as “critical”.

“Prompt and unified steps is required to address this risk. In collaboration with member countries, the EU Commission has put in place an European Union-wide monitoring system for pollinators based on the EU nature restoration regulation, which will help to track our development. Now, we need to prioritize execution and cooperation with participating nations to preserve our pollinators,” she said.

The publication of the evaluations of bees along with butterflies follows the initial Europe-wide study on hoverflies, another vital pollinator group. Released in twenty-twenty-two, it disclosed that over one-third of all hoverfly types in the European continent were threatened with extinction.
