The number of wild bee types in European nations experiencing dying out has more than doubled during the previous ten-year period, whereas the number of endangered butterfly has nearly doubled.
This critical situation for essential pollinating insects was disclosed by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least over 170 bee types out of 1,928 were threatened with extinction in Europe.
The number of butterfly species at risk of extinction in the European continent has increased from 37 to 65 since the previous assessment, carried out over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
In addition to their aesthetic appeal and cultural significance, pollinating species like bees along with butterflies are essential supports for our well-being, our food chains and our economies – maintaining the fruits, veggies and seeds that nourish us,” said the IUCN’s director general. “The newest European red list evaluations reveal serious challenges, with risks growing for butterfly types and vital non-managed bee varieties.”
The factors of the quick recent decreases are the persistent destruction or damage of habitats caused by agricultural intensification and deserted farmland, draining of wetlands, excessive grazing by animals, and the utilization of pesticides and fertilisers including neonicotinoid pesticides. The fragmentation of habitat friendly to pollinators greatly increases the threat of disappearances in specific areas.
Global heating is also shown to be a significant danger: 52% of all at-risk butterfly species in European nations are threatened by the climate change crisis – approximately double the number as a ten years ago.
Nearly ninety percent of flowering plants in the European continent require insect pollination, as per the wild bee assessment’s lead coordinator. “Sadly, non-managed bee populations are in drastic decline and cannot readily be substituted by domesticated hives,” he said. “If native bees vanish, many non-cultivated plants might be at risk too – of which meadows rich in flowers and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebees, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, famous for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the European continent and the sole species of this genus in the European continent, is now classified as critically at risk – the scientific category closest to dying out in natural habitats.
Butterflies that are solely present on mountain peaks are highly susceptible to global heating as they need to move uphill as their living spaces become hotter but in the end exhaust available space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue are among more than 40% of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean, types such as the severely threatened Karpathos grayling butterfly are threatened by extreme dry conditions and fires.
In the meantime, in the Arctic Circle, climate change is resulting in the tree line to advance northwards by many meters each year, with underbrush invading bog and tundra. Warmer conditions also mean reindeer can not anymore cross the ice sheets to graze northern grasslands and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this area, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The largest living space for all these pollinators is grassland rich in flowers and that is disappearing very fast throughout the European continent because of all these reasons,” stated Martin Warren. “The good news is that so many citizens are aware now and there’s a lot more understanding. Under the European Union nature restoration law, all member countries have to turn around the decline in pollinating species by twenty-thirty, and they are going to have to initiate measures. There are landowners who are engaged. Let’s hope they can get the encouragements that will support them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of steps for pollinating species which will not lower food production – and could improve it – such as growers establishing bloom-filled edges around their fields.
EU commissioner for environment, portrayed the conservation status of wild bees, butterflies and other pollinators as “critical”.
“Prompt and unified steps is necessary to tackle this risk. Along with member countries, the Commission of the European Union has implemented an Europe-wide observation system for pollinating species based on the European Union nature restoration legislation, which will assist in monitoring our advancement. Now, we need to prioritize implementation and collaboration with participating nations to protect our pollinators,” she said.
The release of the assessments on bees and butterflies follows the initial European-wide evaluation of hoverflies, an additional vital pollinator group. Issued in twenty-twenty-two, it showed that thirty-seven percent of all hoverfly species in European nations were at risk of extinction.
