Wildzy and the 13cm Gap That Reconnects a Terraced Street

A fence line is not a border for a hedgehog

On a wet Tuesday in late autumn, a hedgehog can cover more than a kilometre looking for beetles, worms and a dry place to nest. The limiting factor in a suburban terrace is rarely food. It is connected cover. A solid fence turns a row of gardens into isolated islands, and every extra road crossing adds risk.

The cause is often neatness, not cruelty

New gravel boards, concrete posts and close-fitting panels are sold as low-maintenance. They keep dogs in and weeds out, but they also seal the routes that hedgehogs use between feeding patches. The fix is not a messy garden or a wildlife reserve. It is a deliberate, maintained gap in the right place.

What the wildzy approach asks you to do first

The wildzy method starts with a route map rather than a shopping list. Walk the boundary at dusk, note droppings, flattened grass or gaps already scratched under a gate, and choose a low-traffic corner away from a road. A 13cm square opening under a fence, or a 15cm channel beneath a gate, is enough for a hedgehog but too small for most pets. Keep the opening clear of stones and check it after storms.

Three checks before cutting

• Confirm the fence is yours to alter, or get written permission from the owner.
• Check for buried cables, irrigation pipes and gas lines before any saw or spade goes in.
• Leave a rough edge rather than a sharp one, and line the tunnel with soil or leaf litter.

Why one gap is not the same as a corridor

A single hole helps one animal cross one boundary. A corridor needs neighbours to repeat the same small change. On a terraced street, three gardens in a row can turn a dead end into a through-route. The result is practical rather than romantic: fewer walled-in young hedgehogs, more access to beetle-rich borders, and less pressure to cross the road. That is the working promise of wildzy: not a rewilded estate, but a chain of small, maintained openings that lets wildlife use the gardens already there.

The maintenance routine that keeps the route open

Gaps fail quietly. Leaf litter blocks them, edging stones shift, and a new fence panel can close a route that worked last year. A ten-minute check each season is enough: clear the opening, trim back growth that narrows it, and note any fresh droppings as evidence the route is still in use. If a neighbour has already cut a gap, align yours with theirs rather than adding a second opening a few metres away. Hedgehogs follow edges, so a straight, predictable line under fences is more useful than a scattered set of holes.

That modest habit is where wildzy earns its keep. The aim is not to transform a garden into a wilderness. It is to make one small, repeatable repair in a boundary that was never meant to be a wall.
