The number of native bee types in the European continent facing disappearance has more than doubled over the past decade, whereas the count of at-risk butterfly has close to doubled.
This dire scenario for crucial pollinating species was disclosed by research studies for the red list of threatened species, which established that at least one hundred seventy-two bee species out of over 1900 were at risk of extinction in Europe.
The total of butterfly species facing extinction in Europe has increased from thirty-seven to 65 since the last study, conducted a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
Apart from their beauty and cultural importance, pollinating insects like bees along with butterflies are crucial elements for our health, our food chains and our financial structures – maintaining the fruits, veggies and seeds that feed us,” said the IUCN director general. “The newest European red list evaluations reveal serious challenges, with threats increasing for butterflies and vital wild bee varieties.”
The reasons of the swift recent drops are the ongoing damage or destruction of habitats caused by farming intensification and deserted farmland, draining of wetlands, livestock overgrazing, and the application of chemical fertilisers and pesticides including neonicotinoids. The breaking up of pollinator-friendly habitat substantially boosts the risk of disappearances in specific areas.
Global warming is also revealed to be a primary risk: 52% of all endangered butterfly species in European nations are imperilled by the climate emergency – approximately twice as many as a decade ago.
Up to 90% of blooming plants in the European continent rely on insect pollination, as stated by Dr Denis Michez. “Unfortunately, wild bee groups are in severe drop and cannot readily be substituted by managed colonies,” he said. “If native bees die out, many native plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a couple of instances.”
15 varieties of bumblebees, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee species, known for aiding tree pollination such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species unique to the continent and the only species of this genus group in European nations, is now evaluated as critically endangered – the scientific classification closest to extinction in the wild.
Butterfly species that are solely present on high-altitude areas are particularly vulnerable to global heating as they must ascend higher as their environments become warmer but ultimately run out of space. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue are among over forty percent of types unique to Europe (exclusive to Europe) at risk of extinction.
In the Mediterranean, types such as the highly at-risk grayling of Karpathos are endangered by extreme wildfires and drought.
At the same time, in the Far North, global heating is resulting in the timberline to shift northward by many meters each year, with scrub taking over wetlands and tundra. Warmer conditions also mean reindeer can no more cross the ice to graze Arctic meadows and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this zone, including Freyja’s fritillary and the ringlet of the Arctic.
“The greatest living space for all these pollinating species is grassland rich in flowers and that is vanishing rapidly across European nations because of all these elements,” remarked Martin Warren. “The encouraging aspect is that so many individuals are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all member states have to reverse the drop in pollinating species by the year 2030, and they are going to have to initiate measures. There are land holders who are involved. We hope they can receive the encouragements that will support them on their way.”
As per Warren, there is “low-hanging fruit” in terms of action for pollinators which will not lower food production – and might boost it – such as farmers creating bloom-filled edges around their fields.
Jessika Roswall, characterized the preservation condition of wild bees, butterflies and other pollinators as “dire”.
“Urgent and collective action is necessary to address this danger. Along with participating nations, the EU Commission has established an Europe-wide tracking system for pollinating species based on the European Union nature restoration legislation, which will aid in following our development. Now, we need to focus on application and collaboration with participating nations to protect our pollinators,” she said.
The publication of the assessments on bees and butterflies follows the initial EU-wide study on hoverflies, a further vital pollinator group. Released in twenty-twenty-two, it disclosed that thirty-seven percent of all hoverfly species in the European continent were threatened with extinction.
