The number of wild bee species in Europe experiencing disappearance has over doubled during the previous ten-year period, and the count of at-risk butterfly species has almost doubled.
This critical situation for crucial pollinating species was disclosed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which determined that at least over 170 bee species out of over 1900 were at risk of extinction in the European continent.
The number of butterflies at risk of extinction in European nations has risen from over thirty-five to sixty-five since the last study, performed over a decade past. One species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.
Apart from their beauty and cultural importance, pollinating species like bees along with butterflies are lifelines for our well-being, our food chains and our financial structures – supporting the fruits, veggies and seeds that sustain us,” stated the IUCN director general. “The latest assessments of the European red list reveal significant difficulties, with threats increasing for butterflies and essential wild bee types.”
The reasons of the rapid recent declines are the continuing harm or degradation of natural habitats caused by intensive agriculture and deserted farmland, draining wetlands, overgrazing by livestock, and the application of chemical fertilisers and pesticides including neonicotinoid chemicals. The division of habitat friendly to pollinators significantly raises the danger of local extinctions.
Global heating is also shown to be a primary risk: Fifty-two percent of all at-risk butterfly species in European nations are imperilled by the climate crisis – roughly double the number as a ten years ago.
As many as 90% of flowering plants in Europe depend on pollination by animals, as stated by the wild bee assessment’s lead coordinator. “Regrettably, wild bee colonies are in sharp decrease and cannot be easily replaced by managed bee colonies,” he said. “If non-managed bees die out, many native plants might be in danger as well – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
Fifteen types of bumblebee types, which play a crucial role in fertilizing peas, beans, peanuts and clover, and 14 types of cellophane bee types, known for fertilizing trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type unique to the European continent and the single type of this genus group in the European continent, is now classified as critically endangered – the scientific category closest to extinction in the wild.
Butterfly species that are only found on mountain tops are highly susceptible to climate change as they have to climb upward as their environments become more heated but in the end have no room left. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue are among more than 40% of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean, varieties such as the severely threatened Karpathos grayling butterfly are imperilled by intense dry conditions and fires.
At the same time, in the Far North, global heating is resulting in the forest boundary to advance northwards by dozens of meters each year, with bushes encroaching on bog and tundra. Warmer conditions also mean Arctic deer can not anymore cross the ice sheets to graze Arctic meadows and maintain them clear. 8 butterfly varieties are threatened with extinction in this region, including Freyja’s fritillary and the ringlet of the Arctic.
“The biggest habitat for all these pollinators is grassland rich in flowers and that is disappearing very fast throughout Europe because of all these reasons,” stated Martin Warren. “The positive thing is that so many individuals are aware now and there’s a lot more consciousness. Under the EU’s nature restoration regulation, all member states have to halt the drop in pollinating species by twenty-thirty, and they are going to have to begin taking action. There are landowners who are involved. It is hoped they can receive the incentives that will help them on their way.”
According to Warren, there is “easy opportunities” in terms of action for pollinating insects which will not lower agricultural output – and may enhance it – such as farmers creating bloom-filled edges around their cultivated areas.
EU commissioner for environment, portrayed the preservation condition of non-managed bees, butterfly species and other pollinating insects as “severe”.
“Immediate and joint measures is required to tackle this danger. In collaboration with member states, the Commission of the European Union has implemented an European Union-wide monitoring system for pollinating species based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to focus on execution and cooperation with participating nations to protect our pollinating species,” she said.
The issuance of the bee and butterfly assessments follows the initial European-wide assessment of hoverflies, an additional crucial pollinating insect category. Issued in 2022, it revealed that over one-third of all hoverfly varieties in European nations were threatened with extinction.
