The count of native bee varieties in European nations facing disappearance has over doubled in the last ten years, while the count of at-risk butterfly types has almost doubled.
This dire scenario for crucial pollinating insects was unveiled by research studies for the IUCN red list, which established that at least over 170 bee species out of nearly two thousand were threatened with extinction in Europe.
The number of butterfly types facing extinction in Europe has increased from thirty-seven to 65 since the last study, conducted over a decade past. One type, the large white of Madeira (Pieris wollastoni) has now been confirmed extinct.
In addition to their visual charm and cultural importance, pollinators like bees and butterflies are lifelines for our physical condition, our food supplies and our financial structures – sustaining the produce, vegetables and seeds that sustain us,” commented the IUCN’s director general. “The newest European red list assessments reveal significant difficulties, with threats growing for butterfly types and crucial non-managed bee types.”
The factors of the swift recent drops are the ongoing damage or destruction of living environments caused by agricultural intensification and abandoned land, draining of wetlands, livestock overgrazing, and the application of pesticides and fertilisers including neonicotinoids. The fragmentation of environments suitable for pollinators significantly raises the danger of extinctions at local level.
Global warming is also revealed to be a significant danger: 52% of all at-risk butterfly types in Europe are imperilled by the climate change crisis – about twofold the amount as a decade ago.
As many as ninety percent of plants that flower in the European continent require animal pollination, as stated by Dr Denis Michez. “Unfortunately, native bee groups are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If native bees disappear, many wild plants might be at risk too – of which flower-rich meadows and lovely orchid types are just a couple of instances.”
Fifteen types of bumblebee species, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 species of cellophane bee types, known for aiding tree pollination such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the mainland and the single type of this genus group in the European continent, is now classified as critically endangered – the scientific classification closest to disappearance in the wild.
Butterfly types that are solely present on mountain peaks are particularly vulnerable to global warming as they must ascend higher as their living spaces become more heated but ultimately run out of space. In Spain’s southern region, the grayling of Nevada and the Andalusian anomalous blue are among more than 40% of types unique to Europe (solely present in Europe) at risk of extinction.
In the Mediterranean region, types such as the critically endangered grayling of Karpathos are imperilled by intense drought and wildfires.
In the meantime, in the Far North, global heating is causing the timberline to move north by dozens of meters each year, with scrub invading bog and tundra. Higher temperatures also mean caribou can not anymore cross the frozen water to feed on Arctic meadows and maintain them clear. 8 butterfly varieties are facing extinction in this zone, including the fritillary of Freyja and the Arctic ringlet butterfly.
“The biggest environment for all these pollinating species is flower-rich grassland and that is declining quickly throughout Europe because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many citizens are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all participating nations have to reverse the decline in pollinating insects by the year 2030, and they are going to have to begin taking action. There are property owners who are interested. We hope they can get the motivations that will assist them on their way.”
As per Warren, there is “low-hanging fruit” in terms of measures for pollinating species which won’t reduce food production – and may enhance it – such as growers creating margins rich in flowers around their fields.
the EU’s environment commissioner, described the conservation status of non-managed bees, butterfly species and other pollinating insects as “critical”.
“Immediate and joint measures is required to address this danger. In collaboration with participating nations, the Commission of the European Union has established an EU-wide observation system for pollinating species based on the EU nature restoration law, which will assist in monitoring our progress. Now, we need to prioritize execution and partnership with member states to preserve our pollinating insects,” she said.
The issuance of the evaluations of bees along with butterflies follows the pioneering EU-wide assessment of hoverflies, an additional crucial pollinating insect category. Published in 2022, it disclosed that thirty-seven percent of all hoverfly varieties in Europe were threatened with extinction.
