Saving Hedgehogs: How Garden Changes Can Prevent Their Extinction

Transform Your Garden into a Hedgehog Haven

Hedgehogs face a steep decline, but simple adjustments in our gardens can reverse this trend. By creating welcoming environments, we can invite these iconic creatures back into our neighborhoods and support local wildlife.

Building Hedgehog Highways and Wildlife-Friendly Spaces

Experts emphasize the importance of installing hedgehog highways—small openings in fences or walls that enable hedgehogs to roam freely between gardens. These pathways are crucial because a single garden rarely provides enough food and mates for a hedgehog’s survival.

“A hedgehog needs to travel to find both a mate and nourishment,” explains wildlife advocate Carvill. “These highways connect fragmented habitats, allowing hedgehogs to safely explore and thrive.”

Understanding Hedgehog Movement and Habitat Needs

Hedgehogs cover impressive distances—up to 3 kilometers (1.9 miles) each night—and their territory can span as much as 20 hectares. This means they frequently travel across multiple gardens in search of resources, making connected green spaces vital for their survival.

Man-Made Threats Endangering Hedgehogs

Unfortunately, numerous human activities contribute to the decline of hedgehog populations. Strimmers and electric lawnmowers often cause accidental injuries, while chemicals like slug pellets poison their food sources. Additionally, vehicles, cattle grids, and garden ponds can pose significant hazards.

By recognizing these threats and adapting our gardening practices, we can create safer, more hospitable environments for hedgehogs and other wildlife.
