Four in 10 of the country’s 1 million insect species are at risk of dying out while numbers of some birds, such as the grey partridge and corn bunting, are also dwindling.
Researchers have described the current trajectory as an “extinction catastrophe”, adding that organic farms were home to up to 50 per cent more wildlife and 30 per cent more species.
The Arc 2031 analysis produced by Horniman Museum looked at animals at particular risk from pesticide use in farming and has been released by Go Organic to mark the first day of Organic September, a month-long celebration highlighting the benefits of organic food for biodiversity.
Arc 2031 ambassador, zoologist and Autumnwatch presenter Megan McCubbin told The Independent: “Every species plays a critical role within an ecosystem and when it comes to farming and agriculture we need to be working with nature and not against it.
“Every species in this list is experiencing some decline or increased threat level because of intensive farming.”
Top of the Arc 2031 list of at-risk species is the grey partridge, which has declined in numbers by 92 per cent between 1970 and 2005.
Corn bunting and the grey long-eared bat are in second and third place, with the former having declined 89 per cent between 1970 and 2003.
Hedgehogs, Essex skippers, small skippers, garden bumblebees, hoverflies, necklace ground beetles and hop flea beetles which serve as pollinators or pest controllers to contribute to a healthy ecosystem make up the rest of the list.
Jo Hatton, principal curator of natural sciences at the Horniman Museum, said: “If we don’t protect biodiversity, it could have profound consequences.”
She added: “Birds such as the grey partridge and butterflies such as the Essex skipper are vital links in our complex ecosystem food webs and help preserve biodiversity – from natural pest controllers to crucial pollinators, the importance of preserving each species cannot be overestimated. It is vital that we protect them.”
