The count of native bee species in the European continent confronting dying out has increased twofold during the previous ten-year period, whereas the count of endangered butterfly species has nearly doubled.
This critical situation for crucial pollinators was unveiled by research studies for the IUCN red list, which determined that at least 172 bee varieties out of over 1900 were facing extinction in the European continent.
The total of butterfly types threatened with extinction in European nations has increased from over thirty-five to over sixty since the earlier research, performed over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
“Beyond their visual charm and cultural importance, pollinating insects like bees and butterflies are crucial elements for our health, our food systems and our economic systems – maintaining the fruits, veggies and seeds that feed us,” commented the IUCN’s director general. “The latest European red list evaluations reveal significant difficulties, with threats increasing for butterfly types and essential wild bee varieties.”
The reasons of the rapid recent declines are the continuing destruction or damage of living environments caused by intensive agriculture and deserted farmland, draining wetlands, excessive grazing by animals, and the utilization of pesticides and fertilisers including neonicotinoids. The division of environments suitable for pollinators significantly raises the risk of local extinctions.
Global heating is also revealed to be a significant danger: Over half of all at-risk butterflies in Europe are endangered by the climate change crisis – roughly twice as many as a ten years ago.
Nearly ninety percent of flowering plants in Europe depend on insect pollination, as per Dr Denis Michez. “Sadly, non-managed bee colonies are in severe drop and cannot readily be substituted by managed bee colonies,” he said. “If native bees die out, many native plants might be in danger as well – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee types, which perform a vital function in fertilizing crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, famous for fertilizing trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the European continent and the single type of this biological genus in European nations, is now evaluated as critically endangered – the research category most akin to dying out in natural habitats.
Butterfly types that are exclusively located on mountain tops are especially at risk to global heating as they have to climb upward as their living spaces become more heated but eventually run out of space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among over forty percent of species endemic to Europe (only found in Europe) facing extinction.
In the Mediterranean region, species such as the critically endangered Karpathos grayling are threatened by extreme dry conditions and fires.
Meanwhile, in the Arctic region, climate change is resulting in the tree line to shift northward by tens of metres each year, with scrub encroaching on marsh and tundra. Warmer conditions also mean caribou can not anymore cross the ice to browse Arctic grasslands and keep them open. 8 butterfly varieties are facing extinction in this area, including the fritillary of Freyja and the ringlet of the Arctic.
“The greatest habitat for all these pollinators is grassland rich in flowers and that is disappearing very fast in European nations because of all these factors,” said one of the lead coordinators of the butterflies assessment. “The positive thing is that so many citizens are concerned now and there’s a lot more consciousness. Under the European Union nature restoration law, all member countries have to reverse the decline in pollinating insects by the year 2030, and they are going to have to start doing something. There are property owners who are interested. Let’s hope they can receive the motivations that will assist them on their way.”
According to the coordinator, there is “easy opportunities” in terms of steps for pollinators which will not lower crop yields – and may enhance it – such as farmers developing margins rich in flowers around their cultivated areas.
Jessika Roswall, characterized the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Immediate and joint measures is required to tackle this danger. In collaboration with member states, the EU Commission has put in place an Europe-wide observation system for pollinating species based on the European Union nature restoration legislation, which will assist in monitoring our development. Now, we need to prioritize application and cooperation with member states to safeguard our pollinating species,” she said.
The release of the bee and butterfly assessments comes after the first Europe-wide assessment of hoverflies, a further vital pollinating insect category. Published in 2022, it revealed that 37% of all hoverfly types in the European continent were threatened with extinction.
