The total of wild bee types in the European continent experiencing extinction has more than doubled during the previous ten-year period, and the count of at-risk butterfly types has nearly doubled.
This pressing issue for vital pollinators was unveiled by research studies for the red list of threatened species, which established that at least over 170 bee varieties out of 1,928 were facing extinction in Europe.
The count of butterfly types facing extinction in European nations has risen from 37 to over sixty since the last study, carried out over a decade past. A single species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
In addition to their beauty and cultural significance, pollinating insects like bees and butterflies are lifelines for our well-being, our food supplies and our financial structures – maintaining the fruits, vegetables and seeds that sustain us,” said the IUCN’s director general. “The newest assessments of the European red list reveal serious challenges, with dangers increasing for butterfly types and essential wild bee types.”
The reasons of the rapid recent declines are the ongoing damage or destruction of habitats caused by intensive agriculture and land abandonment, draining of wetlands, livestock overgrazing, and the utilization of chemical fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of environments suitable for pollinators substantially boosts the risk of disappearances in specific areas.
Global warming is also revealed to be a major threat: 52% of all threatened butterfly species in European nations are threatened by the climate change crisis – approximately double the number as a ten years ago.
Nearly nine out of ten of blooming plants in European nations require insect pollination, according to the wild bee assessment’s lead coordinator. “Sadly, wild bee colonies are in sharp decrease and cannot be easily replaced by domesticated hives,” he said. “If wild bees die out, many wild plants might be threatened too – of which flower-rich meadows and beautiful orchid species are just a few examples.”
Fifteen species of bumblebee species, which play a crucial role in fertilizing peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, recognized for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species found only in the continent and the single type of this biological genus in European nations, is now classified as critically endangered – the scientific classification most akin to extinction in the wild.
Butterfly types that are solely present on high-altitude areas are especially at risk to global warming as they must ascend higher as their habitats become warmer but in the end exhaust available space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue are among over forty percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean region, types such as the critically endangered Karpathos grayling butterfly are endangered by intense dry conditions and fires.
Meanwhile, in the Arctic region, climate change is resulting in the timberline to shift northward by tens of metres each year, with bushes taking over wetlands and tundra. Warmer conditions also mean Arctic deer can not anymore cross the frozen water to graze northern grasslands and maintain them clear. Eight types of butterflies are threatened with extinction in this zone, including Freyja’s fritillary and the Arctic ringlet.
“The biggest habitat for all these pollinating species is grassland rich in flowers and that is disappearing very fast across Europe because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many individuals are concerned now and there’s a lot more understanding. Under the EU nature restoration legislation, all member countries have to turn around the decline in pollinating species by the year 2030, and they are going to have to begin taking action. There are land holders who are interested. We hope they can get the motivations that will assist them on their way.”
As per Warren, there is “easy opportunities” in terms of steps for pollinating insects which will not lower food production – and may enhance it – such as farmers establishing flower-rich margins around their cultivated areas.
EU commissioner for environment, described the protection status of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is needed to tackle this threat. In collaboration with participating nations, the European Commission has implemented an EU-wide tracking system for pollinating species based on the European Union nature restoration legislation, which will help to track our advancement. Now, we need to concentrate on application and partnership with member states to safeguard our pollinators,” she said.
The release of the assessments on bees and butterflies is subsequent to the initial Europe-wide assessment of hoverflies, another essential pollinator group. Issued in twenty-twenty-two, it showed that thirty-seven percent of all hoverfly varieties in Europe were facing extinction.
