The total of native bee types in Europe confronting dying out has over doubled over the past decade, whereas the total of endangered butterfly has nearly doubled.
This dire scenario for vital pollinating species was revealed by research studies for the IUCN red list, which established that at least 172 bee species out of over 1900 were threatened with extinction in the European continent.
The total of butterflies threatened with extinction in European nations has risen from thirty-seven to 65 since the earlier research, performed a decade and a half ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
Apart from their visual charm and cultural importance, pollinators like bees and butterfly species are essential supports for our well-being, our food chains and our financial structures – maintaining the fruits, vegetables and seeds that sustain us,” stated Grethel Aguilar. “The latest assessments of the European red list reveal serious challenges, with threats increasing for butterfly species and crucial non-managed bee types.”
The reasons of the rapid recent declines are the continuing damage or destruction of habitats caused by farming intensification and deserted farmland, draining of wetlands, overgrazing by livestock, and the application of pesticides and fertilisers including neonicotinoids. The fragmentation of environments suitable for pollinators greatly increases the threat of extinctions at local level.
Climate change is also demonstrated to be a significant danger: 52% of all threatened butterfly species in the European continent are threatened by the climate crisis – about twice as many as a previous decade.
Nearly 90% of blooming plants in European nations require animal pollination, as stated by Dr Denis Michez. “Unfortunately, wild bee colonies are in drastic decline and cannot be easily replaced by managed colonies,” he said. “If native bees die out, many native plants might be at risk too – of which meadows rich in flowers and beautiful orchid species are just a couple of instances.”
Fifteen types of bumblebee types, which perform a vital function in aiding the pollination of crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, known for fertilizing trees such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the only species of this genus in the European continent, is now classified as critically at risk – the scientific classification nearest to dying out in natural habitats.
Butterfly types that are only found on mountain tops are particularly vulnerable to global heating as they have to climb upward as their environments become hotter but ultimately run out of space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among above 40 percent of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean area, species such as the highly at-risk Karpathos grayling butterfly are endangered by extreme dry conditions and fires.
At the same time, in the Arctic region, global heating is resulting in the forest boundary to move north by many meters each year, with underbrush invading bog and tundra. Warmer conditions also mean reindeer can not anymore cross the ice to feed on Arctic grasslands and keep them open. Eight types of butterflies are at risk of extinction in this area, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The biggest habitat for all these pollinating insects is grassland rich in flowers and that is disappearing very fast in Europe because of all these reasons,” stated a lead coordinator for the butterfly assessment. “The encouraging aspect is that so many individuals are concerned now and there’s a lot more consciousness. Under the EU nature restoration legislation, all participating nations have to reverse the decrease in pollinating species by twenty-thirty, and they are going to have to begin taking action. There are landowners who are engaged. Let’s hope they can obtain the encouragements that will support them on their way.”
As per the coordinator, there is “low-hanging fruit” in terms of action for pollinators which won’t reduce food production – and could improve it – such as agricultural producers creating bloom-filled edges around their fields.
EU commissioner for environment, described the preservation condition of wild bees, butterflies and other pollinators as “severe”.
“Urgent and collective action is required to tackle this danger. Together with participating nations, the European Commission has established an EU-wide tracking system for pollinating insects based on the European Union nature restoration legislation, which will aid in following our progress. Now, we need to prioritize implementation and collaboration with member states to protect our pollinators,” she said.
The publication of the assessments on bees and butterflies is subsequent to the initial Europe-wide evaluation of hoverflies, another vital pollinating insect category. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly types in the European continent were facing extinction.
