The total of wild bee species in Europe confronting disappearance has over doubled over the past decade, while the total of endangered butterfly species has close to doubled.
This critical situation for vital pollinating species was disclosed by scientific assessments for the red list of threatened species, which found that at least 172 bee varieties out of nearly two thousand were facing extinction in European nations.
The number of butterfly types facing extinction in the European continent has grown from 37 to 65 since the last study, conducted over a decade past. A single species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
In addition to their beauty and cultural significance, pollinating species like bees along with butterflies are lifelines for our physical condition, our food chains and our economies – maintaining the fruits, vegetables and seeds that nourish us,” said the IUCN’s director general. “The most recent European red list assessments reveal major obstacles, with dangers mounting for butterflies and essential non-managed bee varieties.”
The causes of the swift recent drops are the continuing harm or degradation of living environments caused by agricultural intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the application of pesticides and fertilisers including neonicotinoid pesticides. The fragmentation of environments suitable for pollinators significantly raises the threat of extinctions at local level.
Global heating is also shown to be a significant danger: Fifty-two percent of all endangered butterfly species in the European continent are threatened by the climate emergency – approximately double the number as a previous decade.
Nearly ninety percent of blooming plants in Europe rely on insect pollination, according to Dr Denis Michez. “Unfortunately, non-managed bee populations are in severe drop and cannot readily be substituted by managed colonies,” he said. “If native bees disappear, many wild plants might be in danger as well – of which flower-rich meadows and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebee types, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bees, famous for pollinating trees such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species exclusive to the European continent and the only species of this genus group in the European continent, is now classified as severely threatened – the research category closest to extinction in the wild.
Butterflies that are exclusively located on mountain peaks are particularly vulnerable to global heating as they have to climb upward as their environments become hotter but in the end run out of space. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue are among above 40 percent of species endemic to Europe (solely present in Europe) facing extinction.
In the Mediterranean, types such as the severely threatened grayling of Karpathos are endangered by intense wildfires and drought.
In the meantime, in the Arctic Circle, global warming is leading to the forest boundary to shift northward by dozens of meters each year, with bushes taking over bog and tundra. Hotter climates also mean caribou can no more cross the frozen water to feed on Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this region, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The greatest habitat for all these pollinators is bloom-filled grassy areas and that is vanishing rapidly in European nations because of all these elements,” said one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many people are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all participating nations have to reverse the drop in pollinators by twenty-thirty, and they are going to have to start doing something. There are landowners who are interested. We hope they can get the incentives that will support them on their way.”
According to the coordinator, there is “easy opportunities” in terms of measures for pollinating species which will not decrease food production – and may enhance it – such as growers developing flower-rich margins around their fields.
Jessika Roswall, characterized the preservation condition of native bees, butterflies and additional pollinators as “critical”.
“Urgent and collective action is required to tackle this threat. In collaboration with participating nations, the Commission of the European Union has implemented an Europe-wide tracking system for pollinating insects based on the EU nature restoration regulation, which will aid in following our development. Now, we need to focus on execution and cooperation with member states to safeguard our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies follows the initial European-wide study on hoverflies, a further essential pollinating insect category. Released in 2022, it revealed that thirty-seven percent of all hoverfly species in European nations were at risk of extinction.
