Alarming Rise in Endangered Non-Managed Bee Species In Europe
The total of wild bee varieties in European nations facing disappearance has over doubled during the previous ten-year period, and the number of at-risk butterfly species has almost doubled.
This pressing issue for crucial pollinating species was revealed by research studies for the red list of threatened species, which established that at least one hundred seventy-two bee species out of 1,928 were facing extinction in Europe.
The count of butterflies at risk of extinction in the European continent has risen from thirty-seven to 65 since the previous assessment, conducted 14 years ago. A single species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.
“Beyond their beauty and cultural significance, pollinating insects like bees along with butterflies are crucial elements for our health, our food systems and our financial structures – supporting the fruits, veggies and seeds that feed us,” stated the IUCN’s director general. “The latest European red list assessments reveal serious challenges, with risks mounting for butterflies and essential non-managed bee varieties.”
The reasons of the rapid recent declines are the continuing destruction or damage of living environments caused by agricultural intensification and deserted farmland, draining wetlands, livestock overgrazing, and the application of pesticides and fertilisers including neonicotinoid chemicals. The fragmentation of pollinator-friendly habitat substantially boosts the risk of local extinctions.
Global warming is also revealed to be a significant danger: Fifty-two percent of all threatened butterfly types in European nations are imperilled by the climate emergency – roughly twofold the amount as a decade ago.
Up to nine out of ten of flowering plants in the European continent rely on insect pollination, as per the wild bee assessment’s lead coordinator. “Unfortunately, native bee populations are in severe drop and cannot readily be substituted by managed bee colonies,” he said. “If non-managed bees disappear, many non-cultivated plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a few examples.”
15 varieties of bumblebee species, which play a crucial role in fertilizing legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee types, known for pollinating trees such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species unique to the European continent and the single type of this genus in the European continent, is now assessed as critically endangered – the research category most akin to extinction in the wild.
Butterfly types that are only found on mountain peaks are highly susceptible to climate change as they need to move uphill as their living spaces become more heated but eventually have no room left. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue butterfly are among more than 40% of European endemics (only found in Europe) facing extinction.
In the Mediterranean, varieties such as the highly at-risk Karpathos grayling are imperilled by extreme wildfires and drought.
Meanwhile, in the Arctic Circle, global heating is leading to the forest boundary to shift northward by tens of metres each year, with bushes invading marsh and tundra. Warmer conditions also mean caribou can no longer cross the ice sheets to feed on northern grasslands and keep them open. Eight types of butterflies are threatened with extinction in this area, including Freyja’s fritillary and the ringlet of the Arctic.
“The largest environment for all these pollinating species is flower-rich grassland and that is disappearing very fast throughout European nations because of all these elements,” said Martin Warren. “The encouraging aspect is that so many citizens care now and there’s a lot more understanding. Under the European Union nature restoration law, all member states have to halt the drop in pollinators by 2030, and they are going to have to begin taking action. There are landowners who are engaged. We hope they can receive the encouragements that will support them on their way.”
As per Martin Warren, there is “low-hanging fruit” in terms of steps for pollinators which will not decrease food production – and may enhance it – such as growers establishing margins rich in flowers around their fields.
Jessika Roswall, described the protection status of wild bees, butterflies and other pollinators as “severe”.
“Urgent and collective action is needed to tackle this threat. Along with participating nations, the EU Commission has established an EU-wide monitoring system for pollinating insects based on the EU nature restoration law, which will aid in following our development. Now, we need to concentrate on execution and collaboration with member countries to protect our pollinating species,” she said.
The issuance of the bee and butterfly assessments comes after the first EU-wide evaluation of hoverflies, another vital pollinating insect category. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly types in European nations were threatened with extinction.
