Hedgehog highway – attach it to a fence (or any other barrier in your garden) and cut a corridor for hedgehogs to move between gardens. The steel frame creates a small corridor between gardens giving easy access to our spikey friends! Sadly, the UK has lost more than a third of its native hedgehog population in the last 50 years due to habitat loss and fragmentation. Hedgehogs need our help! A single garden is far too small for a hedgehog’s survival. Creating wildlife corridors between gardens is a fun and super-simple way to help! Adult hogs can roam as far as 3km a night, especially in search of a mate.
