The count of native bee species in Europe confronting dying out has over doubled over the past decade, whereas the total of threatened butterfly types has almost doubled.
This dire scenario for vital pollinating species was revealed by scientific assessments for the International Union for Conservation of Nature (IUCN) red list, which found that at least over 170 bee types out of over 1900 were at risk of extinction in European nations.
The total of butterfly species facing extinction in European nations has grown from over thirty-five to over sixty since the last study, performed over a decade past. One type, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
“Beyond their beauty and cultural significance, pollinators like bees along with butterflies are crucial elements for our physical condition, our food chains and our economies – supporting the fruits, vegetables and seeds that feed us,” commented Grethel Aguilar. “The most recent European red list assessments reveal significant difficulties, with risks increasing for butterflies and essential non-managed bee types.”
The reasons of the rapid recent declines are the persistent harm or degradation of living environments caused by intensive agriculture and deserted farmland, wetland drainage, overgrazing by livestock, and the utilization of chemical fertilisers and pesticides including neonicotinoid pesticides. The breaking up of habitat friendly to pollinators significantly raises the threat of disappearances in specific areas.
Global warming is also shown to be a significant danger: Over half of all threatened butterfly types in Europe are threatened by the climate emergency – roughly twofold the amount as a ten years ago.
Up to ninety percent of plants that flower in European nations rely on pollination by animals, as per Dr Denis Michez. “Unfortunately, wild bee groups are in sharp decrease and are not easily replaceable by domesticated hives,” he said. “If non-managed bees die out, many non-cultivated plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a handful of illustrations.”
Fifteen types of bumblebee types, which have an essential part in pollinating crops such as peas, beans, peanuts and clover, and 14 species of cellophane bees, known for pollinating trees such as willows along with red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee unique to the European continent and the sole species of this biological genus in the European continent, is now classified as severely threatened – the scientific classification closest to extinction in the wild.
Butterfly species that are solely present on high-altitude areas are particularly vulnerable to global warming as they have to climb upward as their living spaces become more heated but ultimately have no room left. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among more than 40% of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean area, species such as the highly at-risk grayling of Karpathos are threatened by intense drought and wildfires.
In the meantime, in the Far North, global heating is resulting in the timberline to shift northward by many meters each year, with scrub invading marsh and tundra. Hotter climates also mean Arctic deer can no longer cross the ice to feed on Arctic meadows and maintain them clear. 8 butterfly varieties are facing extinction in this region, including Freyja’s fritillary butterfly and the ringlet of the Arctic.
“The biggest living space for all these pollinators is grassland rich in flowers and that is declining quickly in European nations because of all these factors,” remarked Martin Warren. “The good news is that so many people are concerned now and there’s a lot more consciousness. Under the European Union nature restoration law, all member countries have to turn around the decrease in pollinators by the year 2030, and they are going to have to begin taking action. There are property owners who are involved. Let’s hope they can obtain the motivations that will assist them on their way.”
As stated by Martin Warren, there is “low-hanging fruit” in terms of measures for pollinators which will not decrease crop yields – and might boost it – such as farmers developing margins rich in flowers around their cultivated areas.
Jessika Roswall, characterized the conservation status of wild bees, butterflies and other pollinators as “severe”.
“Prompt and unified steps is needed to confront this danger. Along with member states, the Commission of the European Union has established an Europe-wide tracking system for pollinating species based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to focus on application and cooperation with member countries to safeguard our pollinating species,” she said.
The publication of the assessments on bees and butterflies comes after the pioneering European-wide assessment of hoverflies, another essential pollinator group. Released in twenty-twenty-two, it showed that thirty-seven percent of all hoverfly species in Europe were facing extinction.
