Hedgehogs: How you can help
We've lost a quarter of the hedgehogs in the UK over the last decade. Habitat loss is thought to be a major contributing factor to this crisis. But there's a rather clever new way for you to help hedgehogs and we've discovered an exciting hands-on activity you can do to find out if you've got prickly visitors in your garden.

The project aims to link up hedgehog-friendly habitats in urban environments to help them find food and shelter. It involves the collaboration of communities along the same road to help link up their gardens.
If you want to become a hedgehog champion for your street go to the Hedgehog Street website and order your pack to get started making your road a hedgehog-friendly place.

Once you've joined Hedgehog Street or even if you just want to find out whether you've got hedgehogs visiting your garden there's a clever way that The Mammal Society has developed with Nottingham Trent University.

By using simple materials you can encourage your visitors through a safe tunnel where they will leave behind tell-tale prints of their visit. Simply assemble the materials you need and follow the downloadable instructions (28KB). The Mammal Society's simple guide to mammal prints will help you identify your visitors.
