Attracting Wildlife to Your Garden with Dead Hedge and Dead Wall Structures

Dead Hedges & Wildlife Walls: Beautiful, Functional Havens for Nature

These natural and organic structures are a wonderful way to encourage wildlife into your garden and increase local biodiversity. They provide ideal habitats for a range of species, while also recycling green waste such as grass clippings, leaves, branches, twigs, deadwood, hedge trimmings, and brambles. Even prickly materials like dog rose, holly, and blackthorn play an important role—offering protective cover and nesting security for birds by deterring predators like weasels and stoats and creating a natural early warning system through rustling sounds.

These structures go by many names—deadwall, dead hedge, deadwood pile, rustic woodpile, wildlife hedge, bug house fence, beetle bank, brash pile, fedge (fence + hedge), permaculture mound, and more. No matter what you call them, they serve the same purpose: a haven for wildlife—a living “bug hotel.”

Some are tightly constructed like log fences; others are looser, resembling long, leafy piles. You’ll find them in woodland parks, schools, educational centres, nature reserves, and increasingly, in private gardens.

Sometimes they stand alone; other times, they’re attached to fences or walls. In wooded areas, they may line pathways to form a wildlife corridor. As awareness grows, more homeowners are embracing these eco-structures in their own outdoor spaces.

What Is a Dead Hedge?

At its core, a dead hedge is a natural barrier made by layering dead plant material into a frame—an “eco-skeleton” of your design. It serves as a long-term habitat for insects, pollinators, and small mammals while helping to eliminate green waste.

Traditionally, garden offcuts were called brashings, though nowadays we use the term arisings. Building a dead hedge means you no longer need to bag these up and cart them to the tip. Instead, you’re returning them to the land in a purposeful way.

Historically, large-scale operations burned green waste or used heavy machinery to remove it, which damaged the soil and disrupted fungi and other essential organisms. Today, a more mindful approach sees this material either composted or incorporated into natural structures like deadwalls.

How to Build One

I’ve built many bug hotels over the years, but only a few full dead hedges that are still maintained—at Gazen Salts Nature Reserve, on my allotment, and in a client’s garden.

To build your own:

Start with a frame or skeleton using logs, sturdy branches, twigs, or even natural rocks.
Layer in materials such as cut branches, leaves, brash, roots, brambles, grass clippings, straw, and hay. Over time, keep topping it up.
Add a ground base—dried or composted leaf mulch makes a fantastic base layer, kickstarting the decomposition process.
Maintain regularly by adding more waste to the top. The structure naturally breaks down from the bottom up, enriching the soil as it does.

Eventually, mosses, lichens, fungi, and even living plants will colonise the hedge. You can also plant around it to encourage a living/dead hybrid that blends beautifully into the garden.

Who Lives There?

These hedges are a magnet for all sorts of wildlife:

Insects: beetles (including stag beetles), bees, butterflies, ladybirds
Invertebrates: spiders, woodlice
Amphibians & reptiles: frogs, toads, newts, lizards
Mammals: hedgehogs, mice
Birds: dunnocks, wrens, robins, blackbirds

The diversity of life they support is remarkable—and the structure looks far more attractive than a random pile of dead garden waste.

Planning Tips

Location matters: Choose a clear area without existing flora you’d damage by building over.
Design your shape: Decide whether to build against a wall, along a fence line, or as a freestanding structure.
Mark out dimensions: For free-standing hedges, place upright posts or sturdy branches 2–3 feet apart to hold everything in place. Tap them firmly into the ground for stability.
Trim upward branches: Ensure everything added presses downward for compact decomposition.

Much like Hügelkultur mounds, dead hedges decompose gradually, returning nutrients to the soil while providing habitat above.

Final Thoughts

Dead hedges, or deadwalls, are not just functional; they’re beautiful, rustic features that give back to nature. Unlike newly planted hedges that can take years to establish, these structures offer immediate benefit for local fauna. Thoughtfully designed and placed, they blend ecological care, gardening practice, and wildlife conservation into one harmonious element.
