The number of wild bee species in the European continent confronting extinction has over doubled in the last ten years, while the number of endangered butterfly has almost doubled.
This dire scenario for crucial pollinating species was disclosed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which determined that at least one hundred seventy-two bee species out of over 1900 were at risk of extinction in European nations.
The total of butterfly species threatened with extinction in European nations has grown from thirty-seven to over sixty since the last study, conducted over a decade past. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
“Beyond their beauty and cultural importance, pollinators like bees and butterfly species are essential supports for our health, our food supplies and our economies – sustaining the fruits, veggies and seeds that nourish us,” commented Grethel Aguilar. “The latest assessments of the European red list reveal significant difficulties, with risks mounting for butterflies and crucial wild bee varieties.”
The factors of the rapid recent declines are the persistent damage or destruction of living environments caused by agricultural intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the utilization of pesticides and fertilisers including neonicotinoids. The division of pollinator-friendly habitat significantly raises the danger of extinctions at local level.
Global warming is also shown to be a major threat: Over half of all threatened butterflies in Europe are imperilled by the climate emergency – roughly twofold the amount as a ten years ago.
As many as nine out of ten of plants that flower in the European continent require insect pollination, according to the lead coordinator of the wild bee assessment. “Sadly, wild bee populations are in sharp decrease and cannot be easily replaced by managed colonies,” he said. “If wild bees disappear, many native plants might be in danger as well – of which bloom-filled grasslands and beautiful orchid species are just a handful of illustrations.”
15 varieties of bumblebee species, which play a crucial role in pollinating peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for aiding tree pollination such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the sole species of this genus in Europe, is now evaluated as severely threatened – the scientific classification closest to disappearance in the wild.
Butterfly types that are solely present on mountain peaks are especially at risk to global warming as they need to move uphill as their living spaces become warmer but ultimately have no room left. In the southern part of Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among more than 40% of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean region, species such as the critically endangered Karpathos grayling butterfly are imperilled by extreme drought and wildfires.
Meanwhile, in the Arctic Circle, global warming is resulting in the tree line to advance northwards by dozens of meters each year, with underbrush encroaching on bog and tundra. Higher temperatures also mean reindeer can no more cross the ice to browse Arctic meadows and keep them open. Eight types of butterflies are facing extinction in this area, including Freyja’s fritillary and the Arctic ringlet.
“The largest living space for all these pollinating insects is bloom-filled grassy areas and that is vanishing rapidly across European nations because of all these elements,” said Martin Warren. “The encouraging aspect is that so many citizens are aware now and there’s a lot more understanding. Under the European Union nature restoration law, all member states have to turn around the decrease in pollinating species by 2030, and they are going to have to initiate measures. There are property owners who are engaged. It is hoped they can receive the encouragements that will support them on their way.”
As per Martin Warren, there is “easy opportunities” in terms of steps for pollinating insects which will not decrease agricultural output – and may enhance it – such as farmers establishing bloom-filled edges around their cultivated areas.
the EU’s environment commissioner, portrayed the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is necessary to confront this risk. In collaboration with member countries, the European Commission has implemented an Europe-wide tracking system for pollinators based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to prioritize application and cooperation with member states to safeguard our pollinating insects,” she said.
The publication of the evaluations of bees along with butterflies is subsequent to the pioneering European-wide study on hoverflies, an additional crucial group of pollinators. Released in twenty-twenty-two, it disclosed that over one-third of all hoverfly species in European nations were facing extinction.
