The count of wild bee types in Europe experiencing disappearance has increased twofold over the past decade, whereas the total of endangered butterfly has almost doubled.
This pressing issue for crucial pollinators was unveiled by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least 172 bee varieties out of over 1900 were threatened with extinction in European nations.
The total of butterflies threatened with extinction in the European continent has risen from over thirty-five to 65 since the previous assessment, carried out 14 years ago. A single species, the Madeiran large white (Pieris wollastoni) has now been confirmed extinct.
In addition to their beauty and cultural value, pollinators like bees along with butterflies are lifelines for our physical condition, our food supplies and our economies – supporting the produce, vegetables and seeds that nourish us,” stated the IUCN director general. “The newest assessments of the European red list reveal serious challenges, with threats mounting for butterfly species and essential non-managed bee types.”
The causes of the swift recent drops are the persistent harm or degradation of natural habitats caused by intensive agriculture and land abandonment, wetland drainage, excessive grazing by animals, and the use of fertilisers and pesticides including neonicotinoids. The breaking up of environments suitable for pollinators significantly raises the danger of local extinctions.
Global warming is also shown to be a significant danger: Over half of all at-risk butterflies in the European continent are endangered by the climate change crisis – approximately twice as many as a ten years ago.
Up to ninety percent of flowering plants in European nations depend on animal pollination, as stated by Dr Denis Michez. “Regrettably, non-managed bee groups are in sharp decrease and cannot readily be substituted by domesticated hives,” he said. “If wild bees disappear, many native plants might be in danger as well – of which bloom-filled grasslands and attractive orchid varieties are just a couple of instances.”
Fifteen types of bumblebee species, which perform a vital function in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 types of cellophane bees, recognized for pollinating trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type exclusive to the continent and the only species of this genus group in Europe, is now assessed as critically at risk – the scientific classification closest to dying out in natural habitats.
Butterflies that are solely present on mountain peaks are especially at risk to climate change as they must ascend higher as their habitats become more heated but ultimately have no room left. In southern Spain, the Nevada grayling and the Andalusian anomalous blue are among more than 40% of species endemic to Europe (exclusive to Europe) threatened with extinction.
In the Mediterranean area, species such as the highly at-risk grayling of Karpathos are threatened by extreme wildfires and drought.
At the same time, in the Far North, global heating is resulting in the forest boundary to shift northward by many meters each year, with underbrush taking over marsh and tundra. Higher temperatures also mean reindeer can no more cross the frozen water to feed on northern grasslands and prevent them from overgrowing. Eight butterfly species are threatened with extinction in this area, including Freyja’s fritillary and the Arctic ringlet.
“The greatest environment for all these pollinating species is grassland rich in flowers and that is disappearing very fast throughout European nations because of all these elements,” stated one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many individuals are concerned now and there’s a lot more awareness. Under the EU nature restoration legislation, all member states have to reverse the decrease in pollinating insects by twenty-thirty, and they are going to have to start doing something. There are land holders who are engaged. We hope they can receive the incentives that will help them on their way.”
According to the coordinator, there is “low-hanging fruit” in terms of measures for pollinating insects which will not lower food production – and might boost it – such as agricultural producers developing bloom-filled edges around their farmland.
the EU’s environment commissioner, portrayed the protection status of native bees, butterflies and additional pollinators as “critical”.
“Prompt and unified steps is needed to tackle this risk. Along with member countries, the EU Commission has established an Europe-wide observation system for pollinators based on the EU nature restoration regulation, which will help to track our advancement. Now, we need to concentrate on application and partnership with member countries to protect our pollinating species,” she said.
The issuance of the evaluations of bees along with butterflies follows the pioneering EU-wide assessment of hoverflies, another vital pollinator group. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly types in the European continent were facing extinction.
