Conservationists are calling for the creation of a "million homes for nature" in gardens and open spaces to in a move to protect UK's struggling wildlife.
The call comes following a report by a coalition of wildlife organisations which found that 60% of species that had been studied had suffered declines in the past few decades.
Garden favourites from starlings to hedgehogs as well as some species of butterfly and ladybird were among those creatures in trouble.
They are all in danger of further declines without work to provide them with better habitats, according to the RSPB, one of the wildlife groups behind the State of Nature report.
The RSPB is encouraging people to take steps such as putting up nest boxes, planting wildflowers or digging ponds in their gardens to help wildlife. The charity hopes the public will create a million new homes for nature under the scheme.
Wildlife in the UK is "in trouble", as almost 2,000 species of birds, animals, insects and plants are known to have declined in the past 50 years.
Some 60% of 3,148 British species studied have seen a reduction in numbers or range, with almost a third (31%) suffering major declines, according to a new report by a coalition of conservation and research organisations.
The report is being launched by Sir David Attenborough: "This ground-breaking report is a stark warning - but it is also a sign of hope.
"For 60 years I have travelled the world exploring the wonders of nature and sharing that wonder with the public. But as a boy my first inspiration came from discovering the UK's own wildlife.
"Our islands have a rich diversity of habitats which support some truly amazing plants and animals.
"We should all be proud of the beauty we find on our own doorstep.
"This report shows that our species are in trouble, with many declining at a worrying rate."
The wet weather in 2012 dampened the spirits for many but Butterflies that feed on grasses benefited greatly from drizzly Britain.
The year, which started with hot weather, saw incessant rain from April which prompted substantial grass growth that benefited species such as meadow browns, ringlets and gatekeeper butterflies.
But most butterfly species struggled in the constantly wet and cool conditions.
The Wider Countryside Butterfly Survey recorded 18,500 meadow brown butterflies across 700 1km squares in the UK countryside in 2012, almost twice as many as in 2011 and the most counted in the four years the study has been running.
