The total of native bee types in European nations confronting extinction has over doubled in the last ten years, whereas the count of at-risk butterfly has nearly doubled.
This pressing issue for crucial pollinating species was disclosed by scientific studies for the red list of threatened species, which determined that at least over 170 bee varieties out of over 1900 were threatened with extinction in the European continent.
The number of butterfly types facing extinction in the European continent has risen from over thirty-five to sixty-five since the earlier research, carried out over a decade past. A single species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
In addition to their beauty and cultural importance, pollinating species like bees and butterfly species are crucial elements for our well-being, our food systems and our financial structures – maintaining the fruits, vegetables and seeds that sustain us,” stated Grethel Aguilar. “The most recent European red list evaluations reveal major obstacles, with dangers growing for butterflies and vital native bee types.”
The reasons of the rapid recent declines are the persistent harm or degradation of living environments caused by intensive agriculture and abandoned land, draining of wetlands, excessive grazing by animals, and the use of fertilisers and pesticides including neonicotinoid chemicals. The division of habitat friendly to pollinators greatly increases the risk of extinctions at local level.
Global heating is also revealed to be a primary risk: Fifty-two percent of all endangered butterflies in Europe are imperilled by the climate change crisis – approximately twofold the amount as a previous decade.
As many as ninety percent of blooming plants in European nations rely on animal pollination, as stated by Dr Denis Michez. “Unfortunately, native bee colonies are in drastic decline and cannot be easily replaced by managed bee colonies,” he said. “If wild bees disappear, many non-cultivated plants might be in danger as well – of which bloom-filled grasslands and lovely orchid types are just a couple of instances.”
15 varieties of bumblebee types, which perform a vital function in pollinating peas, beans, peanuts and clover, and 14 species of cellophane bee types, recognized for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the continent and the only species of this genus group in Europe, is now evaluated as severely threatened – the scientific classification nearest to extinction in the wild.
Butterfly types that are solely present on mountain tops are particularly vulnerable to global warming as they have to climb upward as their living spaces become warmer but in the end run out of space. In southern Spain, the grayling of Nevada and the anomalous blue of Andalusia are among more than 40% of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean, varieties such as the highly at-risk Karpathos grayling are imperilled by extreme wildfires and drought.
In the meantime, in the Arctic region, climate change is leading to the forest boundary to move north by many meters each year, with bushes encroaching on bog and tundra. Higher temperatures also mean Arctic deer can no more cross the frozen water to graze northern grasslands and keep them open. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The greatest environment for all these pollinating species is flower-rich grassland and that is vanishing rapidly throughout European nations because of all these factors,” said Martin Warren. “The encouraging aspect is that so many individuals are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member states have to halt the decrease in pollinating species by the year 2030, and they are going to have to start doing something. There are landowners who are engaged. We hope they can get the encouragements that will help them on their way.”
As per Warren, there is “readily achievable actions” in terms of measures for pollinating species which will not lower crop yields – and may enhance it – such as agricultural producers creating bloom-filled edges around their cultivated areas.
EU commissioner for environment, portrayed the conservation status of non-managed bees, butterfly species and other pollinating insects as “dire”.
“Prompt and unified steps is needed to address this threat. Together with participating nations, the Commission of the European Union has established an Europe-wide monitoring system for pollinators based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to focus on execution and partnership with member states to preserve our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies follows the first Europe-wide evaluation of hoverflies, another crucial pollinator group. Released in 2022, it disclosed that 37% of all hoverfly species in Europe were threatened with extinction.
