The tidy-garden problem

Most suburban gardens lose wildlife not through a single dramatic event but through small acts of tidying. A fallen branch becomes a trip hazard, a stump gets ground out, and a heap of prunings goes to the tip. The result is a clean lawn with fewer places for creatures to shelter, feed, and overwinter. A log pile is a small correction with a long tail: it turns dead wood from waste into a working habitat.

Why dead wood is alive

Decaying wood is not inert. As fungi break it down, they soften the timber and create cracks, galleries, and pockets of moisture. Stag beetle larvae, woodlice, centipedes, and solitary bees use those spaces; frogs and hedgehogs shelter beneath larger logs; wrens and robins hunt the invertebrates that gather there. A single decaying log can support a succession of species for years. The wildzy approach to garden habitats treats the log pile as infrastructure rather than decoration, which is a useful shift: it is a place where the food web runs from fungus to bird.

What gets lost when wood is cleared

Removing dead wood does more than remove shelter. It breaks the damp microclimate that many invertebrates need to survive dry spells. It also removes the slow-release food source that fungi and detritivores depend on. In a garden, the cause is usually convenience: dead wood looks untidy, and tidy is easier to manage. The solution is not to abandon the garden but to concentrate the mess in one deliberate, well-placed pile.

Building a pile that works after dark

A useful log pile is roughly one metre wide and half a metre high, sited in partial shade and away from a house wall. Use untreated wood, keep bark on, and mix diameters: a few thick logs for structure, smaller branches for gaps, and leaf litter at the base. Part-bury the bottom logs to hold moisture. Avoid treated timber, painted offcuts, and sealed pallet wood; these do not decompose cleanly.

• Placement: dappled shade, not deep dry sun.
• Structure: thick logs first, smaller branches wedged on top.
• Edge: leave a rough fringe of leaves and twigs.
• Patience: expect fungi first, then invertebrates, then birds and mammals.

The result: a garden with a night shift

After a season, the pile should feel cooler and damper than the surrounding lawn. Lift a loose log in spring and you may find beetle larvae, slug eggs, or a resting frog; at dusk, watch for hedgehogs working the edge. The takeaway is simple: a log pile is not a relic of neglect but a compact habitat that keeps working when the garden is dark.
