The number of wild bee species in European nations experiencing disappearance has over doubled during the previous ten-year period, and the number of endangered butterfly has close to doubled.
This dire scenario for vital pollinators was unveiled by scientific studies for the red list of threatened species, which established that at least 172 bee types out of 1,928 were facing extinction in Europe.
The count of butterfly types threatened with extinction in the European continent has risen from 37 to sixty-five since the last study, conducted 14 years ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been confirmed extinct.
Apart from their beauty and cultural significance, pollinators like bees and butterflies are crucial elements for our physical condition, our food chains and our economies – supporting the produce, vegetables and seeds that feed us,” said the IUCN’s director general. “The most recent European red list assessments reveal serious challenges, with threats growing for butterfly types and essential wild bee varieties.”
The causes of the quick recent decreases are the ongoing damage or destruction of living environments caused by intensive agriculture and land abandonment, draining of wetlands, overgrazing by livestock, and the utilization of pesticides and fertilisers including neonicotinoids. The division of pollinator-friendly habitat substantially boosts the danger of extinctions at local level.
Global heating is also demonstrated to be a primary risk: Fifty-two percent of all threatened butterfly types in the European continent are threatened by the climate crisis – about twice as many as a decade ago.
As many as 90% of blooming plants in the European continent require animal pollination, as stated by the wild bee assessment’s lead coordinator. “Sadly, native bee colonies are in sharp decrease and cannot readily be substituted by managed bee colonies,” he said. “If wild bees disappear, many wild plants might be at risk too – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen species of bumblebee types, which have an essential part in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, famous for fertilizing trees such as willow trees and red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee species exclusive to the continent and the sole species of this genus group in European nations, is now evaluated as critically at risk – the scientific classification closest to extinction in the wild.
Butterfly types that are solely present on high-altitude areas are highly susceptible to global heating as they have to climb upward as their habitats become warmer but eventually have no room left. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among more than 40% of types unique to Europe (only found in Europe) threatened with extinction.
In the Mediterranean region, types such as the highly at-risk Karpathos grayling are endangered by extreme wildfires and drought.
Meanwhile, in the Far North, climate change is causing the forest boundary to move north by many meters each year, with bushes encroaching on wetlands and tundra. Warmer conditions also mean Arctic deer can not anymore cross the ice sheets to feed on northern grasslands and prevent them from overgrowing. Eight types of butterflies are facing extinction in this zone, including Freyja’s fritillary and the Arctic ringlet.
“The biggest living space for all these pollinating species is flower-rich grassland and that is disappearing very fast in European nations because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The good news is that so many people are concerned now and there’s a lot more awareness. Under the European Union nature restoration law, all member countries have to halt the drop in pollinating insects by the year 2030, and they are going to have to begin taking action. There are land holders who are interested. We hope they can receive the incentives that will assist them on their way.”
According to Warren, there is “easy opportunities” in terms of steps for pollinating insects which will not lower food production – and may enhance it – such as agricultural producers developing bloom-filled edges around their farmland.
Jessika Roswall, described the preservation condition of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is necessary to address this risk. Along with member countries, the Commission of the European Union has implemented an European Union-wide observation system for pollinating insects based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to focus on execution and cooperation with member states to safeguard our pollinators,” she said.
The release of the bee and butterfly assessments follows the first European-wide study on hoverflies, a further essential pollinator group. Issued in twenty-twenty-two, it disclosed that 37% of all hoverfly types in the European continent were facing extinction.
