The number of wild bee species in Europe experiencing dying out has increased twofold over the past decade, whereas the count of at-risk butterfly has almost doubled.
This pressing issue for vital pollinators was revealed by scientific studies for the IUCN red list, which determined that at least one hundred seventy-two bee species out of 1,928 were at risk of extinction in the European continent.
The total of butterfly types facing extinction in Europe has increased from thirty-seven to over sixty since the earlier research, conducted 14 years ago. One type, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
In addition to their aesthetic appeal and cultural value, pollinating species like bees and butterflies are crucial elements for our health, our food chains and our financial structures – sustaining the produce, vegetables and seeds that feed us,” stated Grethel Aguilar. “The newest European red list evaluations reveal significant difficulties, with dangers mounting for butterflies and essential native bee types.”
The factors of the rapid recent declines are the ongoing harm or degradation of living environments caused by farming intensification and deserted farmland, draining wetlands, livestock overgrazing, and the use of pesticides and fertilisers including neonicotinoid pesticides. The fragmentation of habitat friendly to pollinators substantially boosts the threat of disappearances in specific areas.
Global heating is also demonstrated to be a primary risk: 52% of all endangered butterfly types in the European continent are endangered by the climate crisis – approximately double the number as a decade ago.
Nearly nine out of ten of plants that flower in European nations depend on pollination by animals, as per the wild bee assessment’s lead coordinator. “Regrettably, non-managed bee colonies are in severe drop and cannot readily be substituted by domesticated hives,” he said. “If wild bees disappear, many native plants might be threatened too – of which bloom-filled grasslands and beautiful orchid species are just a handful of illustrations.”
Fifteen types of bumblebee types, which perform a vital function in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bees, recognized for fertilizing trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee exclusive to the European continent and the only species of this genus group in Europe, is now classified as critically endangered – the scientific classification closest to dying out in natural habitats.
Butterfly types that are exclusively located on mountain peaks are particularly vulnerable to global warming as they have to climb upward as their habitats become hotter but in the end run out of space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (exclusive to Europe) facing extinction.
In the Mediterranean, species such as the highly at-risk Karpathos grayling are threatened by extreme dry conditions and fires.
In the meantime, in the Arctic Circle, global heating is causing the forest boundary to move north by dozens of meters each year, with bushes taking over bog and tundra. Hotter climates also mean Arctic deer can not anymore cross the ice sheets to browse Arctic meadows and maintain them clear. Eight types of butterflies are threatened with extinction in this area, including Freyja’s fritillary butterfly and the Arctic ringlet butterfly.
“The largest environment for all these pollinating insects is grassland rich in flowers and that is declining quickly across Europe because of all these reasons,” remarked one of the lead coordinators of the butterflies assessment. “The good news is that so many individuals are concerned now and there’s a lot more understanding. Under the EU nature restoration legislation, all member states have to reverse the decline in pollinating species by 2030, and they are going to have to initiate measures. There are landowners who are involved. Let’s hope they can receive the encouragements that will help them on their way.”
According to Martin Warren, there is “readily achievable actions” in terms of action for pollinators which will not lower agricultural output – and might boost it – such as growers creating bloom-filled edges around their fields.
EU commissioner for environment, described the preservation condition of wild bees, butterflies and other pollinators as “critical”.
“Urgent and collective action is needed to tackle this risk. Together with participating nations, the European Commission has established an EU-wide monitoring system for pollinators based on the EU nature restoration regulation, which will help to track our development. Now, we need to focus on execution and cooperation with member countries to safeguard our pollinators,” she said.
The publication of the evaluations of bees along with butterflies follows the initial EU-wide evaluation of hoverflies, an additional essential pollinator group. Published in 2022, it showed that thirty-seven percent of all hoverfly varieties in the European continent were threatened with extinction.
