The count of wild bee types in Europe confronting extinction has over doubled during the previous ten-year period, and the total of at-risk butterfly types has close to doubled.
This dire scenario for essential pollinating insects was revealed by scientific assessments for the IUCN red list, which determined that at least 172 bee varieties out of nearly two thousand were at risk of extinction in European nations.
The total of butterfly types facing extinction in the European continent has risen from 37 to over sixty since the earlier research, carried out a decade and a half ago. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
“Beyond their beauty and cultural importance, pollinating insects like bees and butterfly species are crucial elements for our well-being, our food chains and our economies – maintaining the produce, vegetables and seeds that sustain us,” stated the IUCN’s director general. “The most recent European red list evaluations reveal significant difficulties, with dangers growing for butterfly species and vital native bee varieties.”
The reasons of the quick recent decreases are the continuing destruction or damage of habitats caused by intensive agriculture and deserted farmland, draining of wetlands, livestock overgrazing, and the use of pesticides and fertilisers including neonicotinoid pesticides. The breaking up of environments suitable for pollinators significantly raises the threat of extinctions at local level.
Climate change is also shown to be a primary risk: Fifty-two percent of all threatened butterfly species in Europe are imperilled by the climate change crisis – roughly twice as many as a ten years ago.
Up to 90% of plants that flower in the European continent depend on insect pollination, as stated by Dr Denis Michez. “Unfortunately, non-managed bee groups are in sharp decrease and cannot readily be substituted by domesticated hives,” he said. “If wild bees disappear, many wild plants might be in danger as well – of which bloom-filled grasslands and attractive orchid varieties are just a few examples.”
Fifteen species of bumblebee types, which play a crucial role in pollinating legumes like peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type found only in the European continent and the single type of this genus in Europe, is now classified as critically at risk – the scientific classification closest to dying out in natural habitats.
Butterfly types that are only found on mountain peaks are especially at risk to global heating as they have to climb upward as their living spaces become hotter but in the end exhaust available space. In southern Spain, the Nevada grayling butterfly and the anomalous blue of Andalusia are among above 40 percent of European endemics (exclusive to Europe) threatened with extinction.
In the Mediterranean, types such as the highly at-risk Karpathos grayling are endangered by severe drought and wildfires.
At the same time, in the Arctic region, global warming is resulting in the timberline to move north by dozens of meters each year, with bushes encroaching on bog and tundra. Higher temperatures also mean reindeer can not anymore cross the ice sheets to feed on northern grasslands and prevent them from overgrowing. 8 butterfly varieties are at risk of extinction in this area, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The biggest habitat for all these pollinating insects is grassland rich in flowers and that is declining quickly in the European continent because of all these factors,” stated a lead coordinator for the butterfly assessment. “The positive thing is that so many citizens are concerned now and there’s a lot more understanding. Under the European Union nature restoration law, all participating nations have to turn around the decrease in pollinating species by the year 2030, and they are going to have to begin taking action. There are land holders who are interested. It is hoped they can obtain the incentives that will support them on their way.”
According to the coordinator, there is “readily achievable actions” in terms of steps for pollinators which will not decrease crop yields – and may enhance it – such as farmers creating bloom-filled edges around their cultivated areas.
EU commissioner for environment, portrayed the protection status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Prompt and unified steps is needed to confront this danger. Together with member countries, the Commission of the European Union has implemented an Europe-wide observation system for pollinating insects based on the European Union nature restoration legislation, which will assist in monitoring our progress. Now, we need to concentrate on application and cooperation with member states to safeguard our pollinators,” she said.
The publication of the bee and butterfly assessments is subsequent to the first EU-wide study on hoverflies, an additional vital pollinator group. Released in twenty-twenty-two, it disclosed that 37% of all hoverfly varieties in Europe were at risk of extinction.
