Why We 'Leave the Leaves' for Totnes Hedgehogs 🦔
Biodiversity is the variety of life in your garden—plants, insects, birds, and small mammals all thriving together.

“Why is there so much poop on this short grass?”
It’s a question I’ve been asking myself a lot lately while working in gardens across Totnes. It’s what sent me down this recent "hedgehog hole"—or "hedgehog highway"—of research.
I’ve spent a lot of time talking about why we leave the leaves for winter nesting, but my boots-on-the-ground observations were telling me something new. I kept noticing "hedgehog peel" (their dark, shiny droppings) specifically on the shortest, neatest lawns I maintain.
It turns out, while hedgehogs sleep in the leaves, they survive on the grass.
Key🦔 Poo Identification Features
Appearance: Often has a glistening or metallic sheen due to undigested insect parts like beetle wings or shells.
Texture: Usually firm and solid, often tapered at one or both ends.
Placement: Droppings are typically found scattered individually across lawns, paths, or near feeding areas rather than in clusters or piles.
Contents: If you examine it closely, you may see shiny fragments of exoskeletons, beetle wings, or even berry seeds.The Webcam Proof
I was at a customer’s place last weekend, giving the lawn a tight Short Grass Cut. We’d been chatting about the hedgehog house tucked in her corner, wondering if anyone was home.
The very next morning, she sent me her webcam footage. Within hours of that fresh mow, a local hedgehog was out in the open, "snuffling" across the short turf with total ease. Because the grass was short, he didn't have to fight through a jungle; he had a direct line to the worms and beetles that the fresh cut had exposed.
Caught in the act! Watch how this Totnes local uses the short turf as a high-speed buffet line.
Why the "Short Cut" is a Life-Saver
This journey from "why is there poop here?" to "I see you on camera!" confirmed why your neat lawn is actually a wildlife hero:
The Dinner Bell: Mowing vibrates the ground and clears the "thatch," making it much easier for hedgehogs to grab earthworms that come to the surface at night.
Energy = Survival: To survive the winter, a hedgehog needs to reach at least 600g. Trudging through thick grass is exhausting. Short lawns are like "Hedgehog Highways"—they save vital energy by letting them travel their $1–2\text{km}$ nightly route with ease.
The Safety Mosaic: By keeping the lawn short for hunting but leaving the borders "wild" with leaf litter and log piles, we create the perfect habitat.
My "Active Rewilding" Approach
Because I’m seeing so much activity now, I’ve adapted my gardening style:
Short for Hunting: We keep the main "buffet" areas neat.
Long for Nesting: we tuck habitat piles in the corners.
The "Stop and Check": Since they love the edge where the "short" meets the "long," I always do a thorough hand-check before any strimming.
Next time you see those little dark signatures on your lawn, don't be annoyed—be proud! It means your garden is a vital stop on the Totnes wildlife corridor.
🦔 The Hedgehog Energy Equation
The core theory is that hedgehogs are on a strict "energy budget" as they race to hit a 600g hibernation weight.
totnes gardening
Daily Energy Expenditure (DEE): A typical hedgehog uses about 100kJ per day.
The "Jungle Tax": Moving through thick, matted grass or dense "thatch" is high-resistance and physically exhausting, burning through vital fat reserves.
The "Short Cut" Dividend: A freshly mown, short lawn acts like a "Hedgehog Highway." It can reduce travel effort by up to 10%, saving roughly 10kJ of energy every single night.
The Result: Over one week, this saving adds up to 70kJ—nearly an entire day's worth of energy that the hedgehog can "bank" as fat instead of spending it on movement
If you saw the recent BBC News report, you might have seen some familiar nighttime visitors. Hidden cameras in over 400 gardens revealed just how critical our back gardens have become for the survival of the British hedgehog.
The study highlighted a worrying trend: hedgehog numbers are falling. However, the experts offered a clear solution. They confirmed that features like "leaf litter and log piles" are essential for their survival, providing crucial spots for hibernating and breeding.
The Myth: "Eco-Friendly Means Messy"
Many of my clients in Totnes want to help wildlife, but they worry that leaving "habitats" means letting their garden turn into an overgrown jungle. 🦔
This is where professional maintenance makes the difference.
As you can see in the photo above, we don't just blow leaves away to landfill. We create strategic habitat piles. By tucking these piles into quiet corners or behind planters, we provide the winter shelter the BBC study recommends, without cluttering your patio or pathways.

Going One Step Further 🏡
Alongside leaf management, we actively encourage installing dedicated hedgehog houses in quiet, shady spots.
The goal is to create a "wildlife corridor" through the dense lanes of Totnes. When combined with our Quiet Gardening approach (using low-noise battery tools), we ensure that we aren't scaring off the very creatures we are trying to protect.
The "Hedgehog Highway" Math: Why Every Joule Counts
I’ve been thinking a lot about that
target. For a creature that small, hitting that weight before the frost sets in is a life-or-death race. When we look at their nightly
patrol, the math of "energy in vs. energy out" becomes pretty clear.
Energy Saved = (Effort in Long Grass - Effort in Short Grass) × 🦔 Distance
The Hedgehog Energy Equation
Long Grass (High Resistance): Imagine a human running
through waist-deep snow. It's exhausting and burns through fat reserves needed for hibernation.
Short Grass (The "Hedgehog Highway"): It’s like running on a clear track. By reducing the "drag," the hedgehog saves vital calories.Think of it like this:
The "Jungle" Tax: Forcing a hedgehog to push through thick, matted "thatch" is like us hiking through waist-high snow. It’s a high-energy drain for a low-calorie reward.
The "Short Cut" Dividend: By keeping the turf tight, we’re essentially upgrading them from a dirt track to a paved highway.
Let’s look at the numbers:
If a hedgehog spends most of its nightly energy just moving, a fresh mow can slash that travel cost significantly. By reducing the physical resistance of the grass, we might be saving them of their total daily energy.
In real terms? That’s energy they don't have to burn. Instead of using those calories to fight through the grass, they can bank them as fat. Over a week, that "short grass saving" can be the difference between a hedgehog hitting that
goal or falling short before hibernation.
It’s not just a neat lawn; it’s an energy subsidy for our local wildlife.
The Math of the "Nightly Marathon"
When we talk about a hedgehog traveling
a night, it sounds impressive—but the real story is in the energy cost. Research shows that a hedgehog’s Daily Energy Expenditure (DEE) is about
per day.
To survive the winter, they must reach a critical mass of
. If they are forced to "trudge" through thick, unmaintained grass, it’s like us running a marathon through deep sand—it’s significantly more exhausting than moving on a firm surface.
By providing a Short Grass Cut, we aren't just making it look neat; we are creating an "Energy Highway."
The Calculation: If a clear, short path reduces their travel effort by just
, that’s roughly
of energy saved every single night.
The Result: Over a week, that's over
—an entire day's worth of energy they can put toward building the fat reserves needed to survive hibernation instead of just "paying the toll" to move through your garden.
