According to a new report, commissioned by a group of Wildlife Trusts in the south west, drastic declines in insect numbers look set to have far-reaching consequences for wildlife and people.

The new report, Insect Declines and Why They Matter, is written by invertebrate expert Dave Goulson, Professor of Biology at the University of Sussex, and highlights the real and lasting knock on effects of the declines on insect-eating birds, bats, and fish.

It also outlines the cost to society in terms of the millions in lost revenue and broken ecosystems.

In his report Professor Goulson also highlights a clear path to reversing the worrying rate of decline and suggests measures that could take the nation off the route to what is an ‘imminent ecological disaster’.

The Trusts believe that with a coordinated and concerted action from government, local authorities, food growers and the public, insect populations can recover and thrive once more so they can fulfil their important roles in the ecosystems that support all life.

Professor Goulson said: “Insects make up the bulk of known species on earth and are integral to the functioning of terrestrial and freshwater ecosystems, performing vital roles such as pollination, seed dispersal and nutrient cycling.

“They are also food for numerous larger animals, including birds, bats, fish, amphibians and lizards.

“If we don’t stop the decline of our insects there will be profound consequences for all life on earth.

“And it’s not just our wild bees and pollinators that are declining – these trends are mirrored across a great many other invertebrate species.

“We know the main causes of decline include habitat loss and fragmentation, and the overuse of pesticides.

“Wild insects are routinely exposed to complex cocktails of toxins which can cause either death or disorientation and weakened immune and digestive systems.”

In a sobering warning the report concludes: “The consequences are clear; if insect declines are not halted, terrestrial and freshwater ecosystems will collapse, with profound consequences for human wellbeing.”

Wildlife Trusts across the country are calling for a new Environment Bill to secure the creation of a far-reaching and resilient nature recovery network to reverse the decline of insect populations and all wildlife.

The group are also supporting the introduction of a legally binding pesticide reduction target for the UK.

A number of other countries in Europe already have such targets and are making progress away from routine use of harmful chemicals in green spaces.
