Concerning Rise in At-Risk Non-Managed Bee Varieties Across the European Continent
The count of non-managed bee types in Europe experiencing disappearance has over doubled during the previous ten-year period, and the number of endangered butterfly types has close to doubled.
This dire scenario for vital pollinating insects was revealed by scientific studies for the red list of threatened species, which established that at least one hundred seventy-two bee varieties out of nearly two thousand were threatened with extinction in European nations.
The number of butterfly species facing extinction in Europe has grown from over thirty-five to 65 since the last study, conducted a decade and a half ago. A single species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their aesthetic appeal and cultural value, pollinating insects like bees and butterfly species are essential supports for our physical condition, our food systems and our financial structures – maintaining the fruits, vegetables and seeds that sustain us,” commented the IUCN director general. “The latest European red list assessments reveal serious challenges, with risks mounting for butterfly species and vital native bee species.”
The factors of the swift recent drops are the ongoing harm or degradation of natural habitats caused by intensive agriculture and abandoned land, wetland drainage, overgrazing by livestock, and the utilization of chemical fertilisers and pesticides including neonicotinoids. The breaking up of environments suitable for pollinators significantly raises the danger of disappearances in specific areas.
Climate change is also shown to be a major threat: Over half of all threatened butterfly species in Europe are threatened by the climate emergency – about double the number as a ten years ago.
As many as nine out of ten of plants that flower in European nations require pollination by animals, as per Dr Denis Michez. “Regrettably, non-managed bee groups are in drastic decline and cannot readily be substituted by domesticated hives,” he said. “If native bees vanish, many native plants might be at risk too – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”
15 varieties of bumblebee species, which have an essential part in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, recognized for fertilizing trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type found only in the mainland and the only species of this genus in Europe, is now evaluated as critically endangered – the scientific category closest to dying out in natural habitats.
Butterfly species that are solely present on high-altitude areas are especially at risk to global warming as they need to move uphill as their environments become warmer but eventually have no room left. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean region, species such as the severely threatened Karpathos grayling are endangered by intense dry conditions and fires.
In the meantime, in the Arctic Circle, climate change is resulting in the tree line to shift northward by dozens of meters each year, with underbrush encroaching on marsh and tundra. Warmer conditions also mean caribou can not anymore cross the frozen water to browse Arctic grasslands and keep them open. 8 butterfly varieties are threatened with extinction in this area, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The largest environment for all these pollinators is flower-rich grassland and that is disappearing very fast across European nations because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member countries have to turn around the decline in pollinating species by 2030, and they are going to have to initiate measures. There are property owners who are interested. Let’s hope they can receive the incentives that will help them on their way.”
As stated by Martin Warren, there is “low-hanging fruit” in terms of action for pollinating species which will not decrease agricultural output – and could improve it – such as growers establishing margins rich in flowers around their cultivated areas.
Jessika Roswall, characterized the protection status of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is necessary to address this danger. Along with participating nations, the European Commission has put in place 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 collaboration with member countries to preserve our pollinating species,” she said.
The issuance of the bee and butterfly assessments is subsequent to the initial European-wide evaluation of hoverflies, another vital pollinating insect category. Published in 2022, it revealed that over one-third of all hoverfly species in Europe were threatened with extinction.
