Gardeners across the UK are being urged to cut small holes in their fences this summer to help hedgehogs, a beloved garden creature now critically endangered. The simple act of creating a 13cm by 13cm opening at the base of a fence—known as a "hedgehog highway"—allows these animals to roam freely in search of food, mates, and nesting sites.
Hedgehog Populations in Steep Decline
According to a 2022 study on hedgehogs in Britain, their numbers have fallen by 30 to 75% since the year 2000. Further research indicates that the decline has been ongoing for decades, driven by habitat loss and modern gardening practices. Hedgehogs are among the most adored mammals in the UK, and spotting one foraging on a summer evening is a rare delight.
Why Hedgehogs Need Help This Summer
July is a critical month for hedgehogs as they breed, search for food, and build fat reserves for winter. They primarily eat insects, slugs, worms, and small invertebrates, but also consume fruits like apples and carrots. By providing access to gardens, homeowners can help hedgehogs find sustenance and shelter.
The Wildlife Trust stated, "Hedgehogs need to be able to roam far and wide in search of food, mates and nesting sites – the average hedgehog roams 2km a night."
How to Create a Hedgehog Highway
To make a hedgehog hole, you will need a ruler, pencil, coping saw, and sandpaper. With your neighbour's agreement, remove a fence panel or cut a hole directly using a padsaw. Measure and mark a 13cm by 13cm square at the base of the panel, cut it out, and smooth rough edges with sandpaper. Replace the panel to complete the highway.
Gardeners are encouraged to coordinate with neighbours to connect gardens, creating a network of safe passages. Hedgehogs are excellent natural pest controllers, devouring slugs and snails that damage prized plants.
