The total of non-managed bee species in the European continent facing disappearance has over doubled over the past decade, whereas the count of threatened butterfly species has close to doubled.
This critical situation for crucial pollinating species was unveiled by scientific studies for the red list of threatened species, which established that at least over 170 bee species out of 1,928 were threatened with extinction in European nations.
The number of butterfly species threatened with extinction in Europe has risen from thirty-seven to over sixty since the earlier research, carried out a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
Apart from their aesthetic appeal and cultural significance, pollinators like bees and butterflies are lifelines for our well-being, our food chains and our economic systems – maintaining the fruits, veggies and seeds that sustain us,” said Grethel Aguilar. “The latest European red list assessments reveal significant difficulties, with dangers mounting for butterflies and crucial wild bee species.”
The reasons of the swift recent drops are the continuing harm or degradation of natural habitats caused by intensive agriculture and deserted farmland, wetland drainage, overgrazing by livestock, and the use of pesticides and fertilisers including neonicotinoid pesticides. The breaking up of environments suitable for pollinators significantly raises the risk of local extinctions.
Climate change is also shown to be a primary risk: 52% of all threatened butterflies in European nations are threatened by the climate change crisis – roughly twice as many as a previous decade.
Nearly nine out of ten of plants that flower in Europe require animal pollination, as stated by the lead coordinator of the wild bee assessment. “Regrettably, wild bee groups are in drastic decline and cannot readily be substituted by managed colonies,” he said. “If non-managed bees vanish, many native plants might be at risk too – of which meadows rich in flowers and lovely orchid types are just a couple of instances.”
Fifteen species of bumblebee species, which have an essential part in fertilizing legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee species, famous for fertilizing trees such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the mainland and the sole species of this genus in Europe, is now evaluated as critically endangered – the scientific category most akin to dying out in natural habitats.
Butterflies that are solely present on mountain tops are particularly vulnerable to climate change as they have to climb upward as their environments become more heated but eventually have no room left. In southern Spain, the Nevada grayling and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean area, types such as the highly at-risk grayling of Karpathos are threatened by intense wildfires and drought.
Meanwhile, in the Far North, global heating is resulting in the timberline to shift northward by tens of metres each year, with bushes invading bog and tundra. Warmer conditions also mean Arctic deer can no more cross the ice to browse northern grasslands and prevent them from overgrowing. Eight butterfly species are at risk of extinction in this zone, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The greatest habitat for all these pollinators is grassland rich in flowers and that is declining quickly across European nations because of all these reasons,” stated a lead coordinator for the butterfly assessment. “The good news is that so many individuals are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all participating nations have to halt the drop in pollinators by twenty-thirty, and they are going to have to start doing something. There are landowners who are involved. Let’s hope they can receive the encouragements that will assist them on their way.”
As stated by Warren, there is “low-hanging fruit” in terms of action for pollinators which will not decrease crop yields – and could improve it – such as agricultural producers developing flower-rich margins around their cultivated areas.
Jessika Roswall, portrayed the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Immediate and joint measures is required to tackle this risk. Together with participating nations, the EU Commission has put in place an Europe-wide observation system for pollinating species based on the EU nature restoration law, which will aid in following our development. Now, we need to focus on execution and collaboration with member states to preserve our pollinating species,” she said.
The publication of the assessments on bees and butterflies comes after the first EU-wide assessment of hoverflies, a further essential pollinator group. Issued in 2022, it disclosed that thirty-seven percent of all hoverfly species in Europe were at risk of extinction.
