The total of non-managed bee species in Europe facing extinction has over doubled during the previous ten-year period, whereas the total of endangered butterfly has nearly doubled.
This dire scenario for crucial pollinating insects was unveiled by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which found that at least over 170 bee species out of 1,928 were facing extinction in the European continent.
The total of butterflies at risk of extinction in Europe has grown from over thirty-five to sixty-five since the last study, conducted a decade and a half ago. A single species, the Madeiran large white (Pieris wollastoni) has now been declared extinct.
Apart from their beauty and cultural significance, pollinating species like bees along with butterflies are essential supports for our well-being, our food supplies and our economies – sustaining the fruits, veggies and seeds that nourish us,” stated the IUCN’s director general. “The most recent assessments of the European red list reveal major obstacles, with dangers mounting for butterflies and essential wild bee types.”
The reasons of the swift recent drops are the continuing destruction or damage of natural habitats caused by intensive agriculture and abandoned land, draining wetlands, livestock overgrazing, and the use of fertilisers and pesticides including neonicotinoid pesticides. The fragmentation of habitat friendly to pollinators significantly raises the risk of local extinctions.
Climate change is also revealed to be a significant danger: Over half of all at-risk butterflies in the European continent are imperilled by the climate crisis – about double the number as a ten years ago.
Up to 90% of plants that flower in European nations rely on insect pollination, as per the lead coordinator of the wild bee assessment. “Regrettably, non-managed bee groups are in drastic decline and are not easily replaceable by managed colonies,” he said. “If wild bees die out, many non-cultivated plants might be at risk too – of which meadows rich in flowers and lovely orchid types are just a handful of illustrations.”
15 varieties of bumblebee types, which have an essential part in fertilizing peas, beans, peanuts and clover, and 14 species of cellophane bee species, famous for fertilizing trees such as willows and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type unique to the mainland and the sole species of this biological genus in European nations, is now evaluated as critically endangered – the scientific category nearest to disappearance in the wild.
Butterfly species that are solely present on high-altitude areas are highly susceptible to climate change as they have to climb upward as their living spaces become warmer but in the end exhaust available space. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue butterfly are among above 40 percent of European endemics (solely present in Europe) threatened with extinction.
In the Mediterranean area, species such as the critically endangered grayling of Karpathos are endangered by extreme wildfires and drought.
At the same time, in the Arctic Circle, climate change is resulting in the forest boundary to advance northwards by many meters each year, with bushes invading marsh and tundra. Higher temperatures also mean reindeer can no longer cross the ice sheets to graze northern grasslands and keep them open. Eight types of butterflies are facing extinction in this zone, including Freyja’s fritillary and the Arctic ringlet butterfly.
“The biggest environment for all these pollinating insects is grassland rich in flowers and that is declining quickly across Europe because of all these elements,” said a lead coordinator for the butterfly assessment. “The positive thing is that so many individuals care now and there’s a lot more understanding. Under the EU nature restoration legislation, all member countries have to halt the decrease in pollinating insects by twenty-thirty, and they are going to have to begin taking action. There are land holders who are engaged. It is hoped they can obtain the motivations that will support them on their way.”
According to Martin Warren, there is “low-hanging fruit” in terms of measures for pollinating insects which will not lower food production – and might boost it – such as farmers developing bloom-filled edges around their cultivated areas.
Jessika Roswall, portrayed the conservation status of wild bees, butterflies and other pollinators as “critical”.
“Immediate and joint measures is needed to address this danger. Together with member countries, the European Commission has put in place an EU-wide tracking system for pollinating species based on the EU nature restoration regulation, which will assist in monitoring our development. Now, we need to concentrate on application and partnership with member states to protect our pollinating species,” she said.
The release of the bee and butterfly assessments follows the first EU-wide evaluation of hoverflies, a further crucial pollinating insect category. Issued in 2022, it revealed that thirty-seven percent of all hoverfly varieties in Europe were threatened with extinction.
