The total of native bee varieties in the European continent facing disappearance has increased twofold during the previous ten-year period, while the count of at-risk butterfly types has nearly doubled.
This critical situation for essential pollinating species was disclosed by scientific assessments for the red list of threatened species, which established that at least 172 bee species out of nearly two thousand were at risk of extinction in European nations.
The number of butterfly species at risk of extinction in European nations has increased from over thirty-five to over sixty since the earlier research, carried out 14 years ago. One type, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
“Beyond their visual charm and cultural significance, pollinating species like bees along with butterflies are lifelines for our health, our food systems and our financial structures – supporting the fruits, vegetables and seeds that nourish us,” said Grethel Aguilar. “The most recent European red list assessments reveal major obstacles, with dangers mounting for butterflies and crucial wild bee varieties.”
The factors of the rapid recent declines are the ongoing destruction or damage of natural habitats caused by agricultural intensification and land abandonment, draining wetlands, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoids. The breaking up of pollinator-friendly habitat substantially boosts the danger of disappearances in specific areas.
Climate change is also shown to be a major threat: Fifty-two percent of all threatened butterflies in European nations are endangered by the climate change crisis – about twice as many as a ten years ago.
As many as nine out of ten of blooming plants in European nations require insect pollination, as per the wild bee assessment’s lead coordinator. “Unfortunately, non-managed bee groups are in drastic decline and are not easily replaceable by managed bee colonies,” he said. “If wild bees disappear, many wild plants might be at risk too – of which meadows rich in flowers and beautiful orchid species are just a handful of illustrations.”
15 varieties of bumblebees, which play a crucial role in aiding the pollination of crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the continent and the single type of this genus group in European nations, is now classified as critically at risk – the scientific category most akin to disappearance in the wild.
Butterflies that are exclusively located on mountain peaks are particularly vulnerable to climate change as they must ascend higher as their environments become warmer but eventually have no room left. In the southern part of Spain, the grayling of Nevada and the anomalous blue of Andalusia are among more than 40% of species endemic to Europe (only found in Europe) threatened with extinction.
In the Mediterranean area, varieties such as the severely threatened grayling of Karpathos are imperilled by intense dry conditions and fires.
Meanwhile, in the Far North, global heating is causing the forest boundary to advance northwards by dozens of meters each year, with bushes invading wetlands and tundra. Higher temperatures also mean reindeer can no more cross the ice sheets to browse northern grasslands and maintain them clear. Eight types of butterflies are at risk of extinction in this area, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The biggest environment for all these pollinating species is flower-rich grassland and that is vanishing rapidly across the European continent because of all these elements,” said a lead coordinator for the butterfly assessment. “The positive thing is that so many citizens are concerned now and there’s a lot more understanding. Under the EU nature restoration legislation, all member countries have to halt the drop in pollinating species by 2030, and they are going to have to start doing something. There are landowners who are involved. We hope they can obtain the encouragements that will assist them on their way.”
As stated by the coordinator, there is “low-hanging fruit” in terms of steps for pollinating insects which will not lower crop yields – and may enhance it – such as growers establishing flower-rich margins around their cultivated areas.
the EU’s environment commissioner, portrayed the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Urgent and collective action is necessary to confront this risk. In collaboration with member states, the Commission of the European Union has implemented an Europe-wide tracking system for pollinators based on the European Union nature restoration legislation, which will assist in monitoring our development. Now, we need to concentrate on execution and partnership with member countries to safeguard our pollinating species,” she said.
The release of the evaluations of bees along with butterflies is subsequent to the first Europe-wide assessment of hoverflies, a further crucial group of pollinators. Issued in twenty-twenty-two, it showed that 37% of all hoverfly species in the European continent were facing extinction.
