Volunteering charity CSV, usually associated with strictly human concerns, has decided to throw its weight behind the less mainstream pursuit of saving the hedgehog.
It will launch a campaign this autumn asking people to build hedgehog houses in their gardens and encouraging them to register on its website for advice on hedgehog care.
"Hedgehogs are one of the top three mammals people would be saddest to lose, yet are in sustained decline," said a spokeswoman for CSV.
The campaign, part of the charity's Make a Difference Day, will be run in association with the Hedgehog Preservation Society.
Les Stocker, founder of hedgehog hospital charity Tiggywinkles, said the campaign was crucial. "The hedgehog is such an icon now, so it's ideal that CSV is making everybody aware of its importance," he said.
It remains to be clarified whether hedgehog-friendly activity will be called volunteering in the Government's Citizenship Survey or count towards fast-track citizenship under new immigration laws.
