A third of hedgehogs have been lost in the UK in the last 10 years and now over 34,000 volunteers are helping to stem the decline.
But as Hedgehog Street, a national campaign led by British Hedgehog Preservation Society (BHPS) and People's Trust for Endangered Species (PTES), enters its fourth year, the charities are calling on more people to help their efforts by launching The BIG Hedgehog Map online where people can record their sightings of hedgehogs (dead or alive) and pledge to make a hole in their garden fence.
There are about half a million hectares of garden in the UK, and creating a small hole the size of a CD case in shared garden boundaries removes physical barriers for hedgehogs, which typically travel about a mile each night in order to gather food and search for a mate.
BHPS chief executive Fay Vass said: "To reverse the decline of hedgehogs we need to know where they are, and we need to maintain their living spaces. Please help by telling us when you see hedgehogs and make small holes in your garden fences to create hedgehog highways all across the country. By acting together we can really benefit the species."
