The total of wild bee types in European nations experiencing disappearance has more than doubled during the previous ten-year period, and the total of at-risk butterfly has close to doubled.
This pressing issue for essential pollinating species was disclosed by research studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least over 170 bee varieties out of 1,928 were at risk of extinction in Europe.
The number of butterflies threatened with extinction in European nations has grown from 37 to sixty-five since the earlier research, conducted a decade and a half ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
Apart from their aesthetic appeal and cultural value, pollinating insects like bees and butterflies are lifelines for our physical condition, our food supplies and our economies – supporting the produce, vegetables and seeds that feed us,” said Grethel Aguilar. “The latest European red list assessments reveal major obstacles, with threats growing for butterfly species and vital non-managed bee varieties.”
The causes of the rapid recent declines are the persistent harm or degradation of living environments caused by agricultural intensification and land abandonment, draining of wetlands, livestock overgrazing, and the use of chemical fertilisers and pesticides including neonicotinoids. The breaking up of environments suitable for pollinators significantly raises the danger of extinctions at local level.
Climate change is also shown to be a major threat: 52% of all endangered butterfly types in the European continent are endangered by the climate change crisis – approximately twofold the amount as a previous decade.
Nearly 90% of flowering plants in European nations rely on pollination by animals, as per Dr Denis Michez. “Regrettably, non-managed bee populations are in drastic decline 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 few examples.”
Fifteen species of bumblebee types, which play a crucial role in fertilizing legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee species, famous for pollinating trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species unique to the mainland and the sole species of this biological genus in the European continent, is now evaluated as severely threatened – the scientific category nearest to dying out in natural habitats.
Butterflies that are exclusively located on mountain tops are highly susceptible to global heating as they need to move uphill as their living spaces become more heated but in the end have no room left. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue are among over forty percent of species endemic to Europe (exclusive to Europe) facing extinction.
In the Mediterranean, species such as the critically endangered grayling of Karpathos are imperilled by severe dry conditions and fires.
Meanwhile, in the Arctic Circle, climate change is leading to the forest boundary to advance northwards by dozens of meters each year, with scrub encroaching on wetlands and tundra. Higher temperatures also mean reindeer can no more cross the ice to browse Arctic grasslands and prevent them from overgrowing. Eight types of butterflies are facing extinction in this area, including Freyja’s fritillary and the ringlet of the Arctic.
“The largest habitat for all these pollinating insects is flower-rich grassland and that is declining quickly throughout Europe because of all these reasons,” stated one of the lead coordinators of the butterflies assessment. “The good news is that so many citizens are concerned now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all participating nations have to turn around the decline in pollinating insects by twenty-thirty, and they are going to have to start doing something. There are landowners who are involved. Let’s hope they can receive the motivations that will assist them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of steps for pollinators which will not decrease agricultural output – and could improve it – such as farmers creating margins rich in flowers around their fields.
EU commissioner for environment, portrayed the conservation status of native bees, butterflies and additional pollinators as “critical”.
“Urgent and collective action is needed to tackle this risk. Together with member states, the EU Commission has put in place an European Union-wide tracking system for pollinating insects based on the European Union nature restoration legislation, which will assist in monitoring our development. Now, we need to concentrate on execution and cooperation with participating nations to preserve our pollinating insects,” she said.
The publication of the evaluations of bees along with butterflies follows the first Europe-wide evaluation of hoverflies, another essential pollinator group. Published in 2022, it disclosed that over one-third of all hoverfly types in Europe were facing extinction.
