The number of native bee types in European nations experiencing disappearance has over doubled in the last ten years, and the total of at-risk butterfly species has almost doubled.
This critical situation for essential pollinating insects was disclosed by scientific studies for the red list of threatened species, which established that at least over 170 bee types out of over 1900 were facing extinction in European nations.
The number of butterfly species facing extinction in the European continent has increased from 37 to 65 since the earlier research, performed over a decade past. One type, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their aesthetic appeal and cultural significance, pollinating insects like bees and butterfly species are lifelines for our physical condition, our food systems and our economies – supporting the fruits, veggies and seeds that sustain us,” stated Grethel Aguilar. “The latest European red list assessments reveal serious challenges, with threats growing for butterfly species and vital wild bee types.”
The causes of the rapid recent declines are the persistent destruction or damage of habitats caused by farming intensification and deserted farmland, wetland drainage, overgrazing by livestock, and the application of chemical fertilisers and pesticides including neonicotinoid pesticides. The breaking up of environments suitable for pollinators significantly raises the danger of local extinctions.
Global warming is also demonstrated to be a major threat: Fifty-two percent of all threatened butterfly types in the European continent are imperilled by the climate crisis – approximately twice as many as a ten years ago.
Nearly nine out of ten of plants that flower in Europe require insect pollination, as stated by the wild bee assessment’s lead coordinator. “Unfortunately, non-managed bee groups are in severe drop and are not easily replaceable by managed colonies,” he said. “If native bees vanish, many native plants might be at risk too – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebees, which perform a vital function in fertilizing legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee types, famous for aiding tree pollination such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee unique to the European continent and the sole species of this genus in the European continent, is now assessed as critically endangered – the research category closest to extinction in the wild.
Butterflies that are exclusively located on mountain tops are especially at risk to global heating as they must ascend higher as their environments become more heated but eventually have no room left. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (exclusive to Europe) facing extinction.
In the Mediterranean region, types such as the severely threatened grayling of Karpathos are threatened by extreme dry conditions and fires.
Meanwhile, in the Far North, global heating is leading to the timberline to move north by dozens of meters each year, with scrub encroaching on wetlands and tundra. Hotter climates also mean Arctic deer can no longer cross the ice to graze Arctic 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 greatest living space for all these pollinating insects is grassland rich in flowers and that is declining quickly throughout Europe because of all these reasons,” stated a lead coordinator for the butterfly assessment. “The positive thing is that so many people are aware now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all participating nations have to turn around the decrease in pollinators by the year 2030, and they are going to have to start doing something. There are land holders who are engaged. We hope they can receive the encouragements that will help them on their way.”
As per Warren, there is “easy opportunities” in terms of measures for pollinators which won’t reduce agricultural output – and could improve it – such as growers developing margins rich in flowers around their fields.
EU commissioner for environment, characterized the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is needed to address this risk. Together with participating nations, the European Commission has implemented an Europe-wide tracking system for pollinating species based on the EU nature restoration regulation, which will assist in monitoring our progress. Now, we need to focus on application and collaboration with member states to preserve our pollinators,” she said.
The release of the evaluations of bees along with butterflies follows the initial EU-wide assessment of hoverflies, a further essential group of pollinators. Released in twenty-twenty-two, it disclosed that over one-third of all hoverfly varieties in Europe were facing extinction.
