Worrying Rise in Threatened Non-Managed Bee Species Throughout European Nations
The total of non-managed bee species in European nations confronting extinction has increased twofold during the previous ten-year period, while the number of endangered butterfly has nearly doubled.
This dire scenario for crucial pollinators was disclosed by research studies for the red list of threatened species, which found that at least 172 bee varieties out of 1,928 were threatened with extinction in Europe.
The count of butterfly species threatened with extinction in the European continent has grown from 37 to sixty-five since the previous assessment, conducted a decade and a half ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
“Beyond their beauty and cultural significance, pollinating species like bees and butterfly species are crucial elements for our physical condition, our food chains and our economic systems – supporting the fruits, vegetables and seeds that nourish us,” said the IUCN director general. “The newest European red list assessments reveal major obstacles, with risks growing for butterfly types and vital wild bee varieties.”
The causes of the quick recent decreases are the ongoing damage or destruction of living environments caused by farming intensification and deserted farmland, draining of wetlands, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoids. The fragmentation of pollinator-friendly habitat significantly raises the risk of extinctions at local level.
Global warming is also shown to be a significant danger: 52% of all threatened butterfly types in the European continent are endangered by the climate emergency – about twice as many as a decade ago.
Up to ninety percent of flowering plants in the European continent require insect pollination, as stated by Dr Denis Michez. “Sadly, wild bee colonies are in severe drop and are not easily replaceable by domesticated hives,” he said. “If native bees disappear, many non-cultivated plants might be threatened too – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen species of bumblebee types, which play a crucial role in fertilizing peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, famous for pollinating trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee exclusive to the mainland and the sole species of this genus group in European nations, is now assessed as critically endangered – the scientific category closest to extinction in the wild.
Butterfly species that are solely present on mountain tops are especially at risk to climate change as they need to move uphill as their environments become more heated but ultimately have no room left. In Spain’s southern region, the Nevada grayling butterfly and the anomalous blue of Andalusia are among more than 40% of types unique to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean region, types such as the critically endangered grayling of Karpathos are endangered by severe dry conditions and fires.
In the meantime, in the Arctic region, global warming is leading to the tree line to advance northwards by tens of metres each year, with underbrush encroaching on bog and tundra. Hotter climates also mean caribou can not anymore cross the frozen water to browse Arctic grasslands and maintain them clear. Eight butterfly species are at risk of extinction in this zone, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The biggest living space for all these pollinating insects is bloom-filled grassy areas and that is disappearing very fast throughout European nations because of all these factors,” said a lead coordinator for the butterfly assessment. “The good news is that so many citizens care now and there’s a lot more awareness. Under the European Union nature restoration law, all member countries have to turn around the decline in pollinators by 2030, and they are going to have to start doing something. There are property owners who are interested. It is hoped they can obtain the encouragements that will support them on their way.”
According to Warren, there is “easy opportunities” in terms of steps for pollinating insects which won’t reduce agricultural output – and may enhance it – such as farmers developing margins rich in flowers around their farmland.
the EU’s environment commissioner, portrayed the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Urgent and collective action is required to tackle this risk. Along with participating nations, the EU Commission has implemented an Europe-wide monitoring system for pollinating species based on the EU nature restoration law, which will assist in monitoring our advancement. Now, we need to focus on implementation and partnership with member states to safeguard our pollinators,” she said.
The publication of the assessments on bees and butterflies comes after the initial Europe-wide assessment of hoverflies, a further crucial group of pollinators. Issued in twenty-twenty-two, it showed that over one-third of all hoverfly species in Europe were facing extinction.
