The total of non-managed bee types in Europe experiencing dying out has more than doubled in the last ten years, whereas the total of endangered butterfly has nearly doubled.
This dire scenario for crucial pollinating species was revealed by research studies for the red list of threatened species, which found that at least one hundred seventy-two bee species out of over 1900 were facing extinction in Europe.
The count of butterfly types facing extinction in European nations has grown from 37 to 65 since the earlier research, conducted over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their visual charm and cultural value, pollinators like bees along with butterflies are essential supports for our physical condition, our food chains and our economies – supporting the fruits, vegetables and seeds that sustain us,” stated the IUCN director general. “The latest European red list evaluations reveal serious challenges, with dangers growing for butterfly species and vital wild bee species.”
The causes of the rapid recent declines are the continuing harm or degradation of living environments caused by agricultural intensification and abandoned land, wetland drainage, overgrazing by livestock, and the utilization of chemical fertilisers and pesticides including neonicotinoid pesticides. The breaking up of environments suitable for pollinators substantially boosts the risk of extinctions at local level.
Global warming is also shown to be a major threat: 52% of all endangered butterflies in Europe are threatened by the climate emergency – roughly double the number as a ten years ago.
Up to ninety percent of plants that flower in the European continent rely on pollination by animals, according to Dr Denis Michez. “Regrettably, native bee populations are in sharp decrease and cannot be easily replaced by managed colonies,” he said. “If non-managed bees vanish, many non-cultivated plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a couple of instances.”
Fifteen species of bumblebee types, which have an essential part in fertilizing crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee species, recognized for pollinating trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the continent and the single type of this genus in European nations, is now classified as severely threatened – the scientific classification closest to extinction in the wild.
Butterfly species that are only found on mountain peaks are highly susceptible to global heating as they need to move uphill as their environments become more heated but eventually run out of space. In Spain’s southern region, the grayling of Nevada and the anomalous blue of Andalusia are among above 40 percent of species endemic to Europe (only found in Europe) threatened with extinction.
In the Mediterranean region, varieties such as the highly at-risk Karpathos grayling are threatened by extreme drought and wildfires.
At the same time, in the Arctic region, global heating is resulting in the timberline to move north by many meters each year, with scrub taking over marsh and tundra. Warmer conditions also mean caribou can no more cross the ice sheets to graze Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The biggest environment for all these pollinating insects is flower-rich grassland and that is vanishing rapidly in the European continent because of all these reasons,” said Martin Warren. “The good news is that so many citizens are concerned now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member states have to reverse the drop in pollinating species by twenty-thirty, and they are going to have to initiate measures. There are landowners who are engaged. It is hoped they can receive the incentives that will support them on their way.”
According to the coordinator, there is “readily achievable actions” in terms of measures for pollinating species which will not decrease crop yields – and could improve it – such as farmers developing bloom-filled edges around their farmland.
Jessika Roswall, characterized the protection status of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is necessary to confront this threat. In collaboration with participating nations, the EU Commission has put in place an Europe-wide tracking system for pollinating species based on the EU nature restoration law, which will assist in monitoring our development. Now, we need to concentrate on execution and partnership with member countries to protect our pollinating species,” she said.
The publication of the evaluations of bees along with butterflies is subsequent to the first Europe-wide study on hoverflies, an additional vital pollinating insect category. Published in twenty-twenty-two, it disclosed that thirty-seven percent of all hoverfly varieties in the European continent were facing extinction.
