Warning over rise in invasive species as public told to report Asian hornets
PEOPLE are being urged to report any sightings of Asian hornets this summer as nature groups warn of a potential surge in damaging invasive non-native species.
The UK’S chief plant health officer Nicola Spence has called for beekeepers and the wider public to be increasingly vigilant to the presence of the hornet after record sightings in the country last year.
Asian hornets pose no greater risk to human health than native hornets but threaten honey bees and insect pollinators.
The Environment Department (Defra) said the species is not established in the UK yet but early trapping is fundamental to eradication efforts.
It comes as the Wildlife and Countryside Link (WCL), which represents 83 nature organisations, warned that recent flooding and warming temperatures have increased the risk of problem species already in the UK growing and spreading.
This includes Japanese
Knotweed, which can cause structural damage, Giant Hogweed, with sap that can cause burns to skin, and Himalayan Balsam, which outcompetes native species and increases flood risks. The WCL said the volatile conditions have also increased the risk of new species establishing themselves in the UK, like the Red Imported Fire Ant, Chinese Mitten Crab, and Chinese Mystery Snail, which are making their way across Europe.
Richard Benwell, WCL chief executive, said: “Invasive species are already one of the biggest threats to the UK environment, from smothering waterways to outcompeting native species.
“They also cause billions of pounds in damage a year to homes and businesses, and even pose risks to human health.
The River Trust, Plantlife and Buglife are among the groups in the coalition, which is calling for government action to mark Invasive Non-native Species Week from Monday.
“Investment in a fully-funded inspectorate and a strong invasive species strategy could make a contribution to halting nature’s decline and creating a more resilient economy,” Mr Benwell said.
Dr Rob Collins, director of policy and science at The Rivers Trust, said the weather conditions over winter have left its local trusts “struggling to keep a wave of invasive species at bay” as wet weather scuppers their efforts.
