The number of non-managed bee varieties in Europe facing dying out has over doubled during the previous ten-year period, whereas the total of endangered butterfly species has close to doubled.
This pressing issue for vital pollinating insects was unveiled by research studies for the International Union for Conservation of Nature (IUCN) red list, which established that at least one hundred seventy-two bee species out of 1,928 were facing extinction in Europe.
The number of butterfly species at risk of extinction in Europe has increased from over thirty-five to over sixty since the previous assessment, conducted 14 years ago. A single species, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
“Beyond their beauty and cultural importance, pollinators like bees and butterflies are crucial elements for our well-being, our food systems and our economies – supporting the fruits, vegetables and seeds that feed us,” commented the IUCN director general. “The most recent assessments of the European red list reveal significant difficulties, with risks increasing for butterflies and vital wild bee species.”
The causes of the swift recent drops are the continuing harm or degradation of natural habitats caused by intensive agriculture and abandoned land, wetland drainage, livestock overgrazing, and the application of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of environments suitable for pollinators significantly raises the danger of extinctions at local level.
Global heating is also revealed to be a major threat: Fifty-two percent of all endangered butterflies in Europe are imperilled by the climate change crisis – roughly double the number as a decade ago.
As many as ninety percent of flowering plants in Europe require insect pollination, as per the wild bee assessment’s lead coordinator. “Sadly, wild bee groups are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If non-managed bees vanish, many native plants might be at risk too – of which bloom-filled grasslands and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee types, which perform a vital function in pollinating peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for aiding tree pollination such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee exclusive to the European continent and the sole species of this genus group in European nations, is now classified as critically at risk – the scientific classification most akin to extinction in the wild.
Butterfly types that are solely present on high-altitude areas are particularly vulnerable to global warming as they have to climb upward as their habitats become hotter but eventually have no room left. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue are among over forty percent of species endemic to Europe (only found in Europe) at risk of extinction.
In the Mediterranean, species such as the critically endangered Karpathos grayling butterfly are imperilled by extreme wildfires and drought.
In the meantime, in the Arctic region, global warming is leading to the forest boundary to shift northward by many meters each year, with bushes invading bog and tundra. Hotter climates also mean caribou can no more cross the frozen water to browse Arctic meadows and maintain them clear. 8 butterfly varieties are facing extinction in this area, including the fritillary of Freyja and the Arctic ringlet.
“The biggest living space for all these pollinators is bloom-filled grassy areas and that is declining quickly in the European continent because of all these reasons,” stated Martin Warren. “The encouraging aspect 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 pollinators by 2030, and they are going to have to start doing something. There are land holders who are involved. Let’s hope they can receive the motivations that will help them on their way.”
As per the coordinator, there is “readily achievable actions” in terms of steps for pollinating species which will not decrease food production – and might boost it – such as growers developing bloom-filled edges around their farmland.
EU commissioner for environment, described the conservation status of native bees, butterflies and additional pollinators as “critical”.
“Immediate and joint measures is needed to tackle this threat. Together with member countries, the European Commission has implemented an Europe-wide observation system for pollinators based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to prioritize implementation and collaboration with participating nations to safeguard our pollinating insects,” she said.
The issuance of the evaluations of bees along with butterflies comes after the initial European-wide assessment of hoverflies, a further vital group of pollinators. Published in 2022, it disclosed that over one-third of all hoverfly species in European nations were facing extinction.
