The number of wild bee varieties in the European continent confronting extinction has more than doubled in the last ten years, and the number of endangered butterfly species has nearly doubled.
This dire scenario for crucial pollinating species was disclosed by scientific studies for the red list of threatened species, which found that at least over 170 bee species out of over 1900 were threatened with extinction in Europe.
The count of butterfly species threatened with extinction in European nations has increased from 37 to sixty-five since the previous assessment, conducted a decade and a half ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
In addition to their aesthetic appeal and cultural significance, pollinating insects like bees and butterflies are crucial elements for our physical condition, our food supplies and our economic systems – maintaining the fruits, vegetables and seeds that nourish us,” stated the IUCN’s director general. “The most recent European red list assessments reveal significant difficulties, with threats growing for butterfly types and essential non-managed bee types.”
The causes of the swift recent drops are the ongoing damage or destruction of habitats caused by agricultural intensification and abandoned land, draining of wetlands, livestock overgrazing, and the utilization of fertilisers and pesticides including neonicotinoid chemicals. The breaking up of environments suitable for pollinators greatly increases the risk of disappearances in specific areas.
Global warming is also revealed to be a major threat: 52% of all at-risk butterfly types in Europe are endangered by the climate crisis – about twofold the amount as a previous decade.
Nearly nine out of ten of flowering plants in the European continent depend on animal pollination, as stated by the lead coordinator of the wild bee assessment. “Unfortunately, wild bee colonies 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 types, which have an essential part in aiding the pollination of legumes like peas, beans, peanuts and clover, and 14 types of cellophane bee types, known for pollinating trees such as willow trees and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the continent and the sole species of this genus in European nations, is now classified as critically at risk – the research category most akin to disappearance in the wild.
Butterflies that are only found on mountain tops are particularly vulnerable to climate change as they need to move uphill as their environments become more heated but ultimately have no room left. In southern Spain, the Nevada grayling and the Andalusian anomalous blue butterfly are among more than 40% of species endemic to Europe (solely present in Europe) threatened with extinction.
In the Mediterranean area, varieties such as the severely threatened Karpathos grayling are endangered by intense wildfires and drought.
At the same time, in the Far North, global warming is leading to the forest boundary to move north by many meters each year, with bushes taking over wetlands and tundra. Hotter climates also mean reindeer can not anymore cross the frozen water to feed on Arctic grasslands and prevent them from overgrowing. 8 butterfly varieties are threatened with extinction in this region, including Freyja’s fritillary butterfly and the Arctic ringlet.
“The largest habitat for all these pollinating species is grassland rich in flowers and that is disappearing very fast in the European continent because of all these reasons,” said a lead coordinator for the butterfly assessment. “The positive thing is that so many people are aware now and there’s a lot more consciousness. Under the EU nature restoration legislation, all member countries have to halt the decline in pollinating insects by twenty-thirty, and they are going to have to initiate measures. There are land holders who are interested. It is hoped they can obtain the encouragements that will assist them on their way.”
As stated by the coordinator, there is “readily achievable actions” in terms of steps for pollinating insects which will not decrease crop yields – and might boost it – such as growers establishing bloom-filled edges around their cultivated areas.
the EU’s environment commissioner, portrayed the preservation condition of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is required to tackle this risk. Together with member states, the European Commission has implemented an Europe-wide monitoring system for pollinating insects based on the EU nature restoration law, which will aid in following our progress. Now, we need to prioritize application and collaboration with participating nations to preserve our pollinators,” she said.
The publication of the evaluations of bees along with butterflies is subsequent to the initial Europe-wide assessment of hoverflies, an additional crucial group of pollinators. Issued in twenty-twenty-two, it revealed that over one-third of all hoverfly species in European nations were at risk of extinction.
