Why Leaving Fallen Branches Can Help Save Biodiversity
Every time we “tidy up” our gardens by tossing fallen branches or twigs, we remove what could become valuable wildlife habitat. By creating a simple log pile in a quiet corner of your outdoor space, you offer shelter for small mammals, amphibians, insects, fungi, and even birds. This micro-habitat supports local biodiversity, enhances soil health, and contributes directly to Sustainable Development Goal 15: Life on Land.
And the best part? It requires less work from you.
Quick Stats on Deadwood’s Big Impact
- Deadwood supports up to 30% of forest biodiversity, including pollinators, decomposers, and cavity-nesting species. (Source: FAO: Forest Deadwood Biodiversity Report)
- Insects that depend on decaying wood provide critical ecosystem services, from pollination to nutrient cycling. (Source: UK Woodland Trust – Wildlife in Wood)
- Habitat loss is a key driver of the 1 million species at risk of extinction, according to the UN.

How to Build a Simple, Safe Log Habitat
- Pick a Safe Spot: Choose a shaded, undisturbed corner of your garden or community green space. Avoid spots too close to your home, especially wooden structures.
- Gather Natural Materials: Collect dry logs, fallen branches, twigs, leaves, and bark. Ensure they are untreated and unpainted.
- Stack Thoughtfully: Create a loose pile, allowing spaces between pieces. The looser the structure, the more shelter it offers.
- Let It Be: Resist the urge to disturb it. Over weeks and months, it will become a thriving mini-wildlife sanctuary.
Safety and Caution Tips
While this is a low-effort and safe activity, a few precautions help ensure it’s wildlife-friendly and human-friendly:
- Wear gloves when handling logs to protect against sharp bark, thorns, or insect bites.
- Watch for snakes or other animals that may already be using wood as shelter, especially in rural or warm climates.
- Avoid logs near high-traffic areas, especially if bees, wasps, or small mammals move in.
- Never place near grills, fire pits, or outdoor stoves, as dry wood is flammable.
- Wash hands after handling natural materials, especially before meals or touching your face.
How This Supports SDG 15: Life on Land?
By leaving or stacking fallen wood, you’re actively helping to:
- Restore degraded ecosystems
- Provide habitat for endangered or keystone species
- Maintain local biodiversity without chemicals or invasive landscaping
It’s a grassroots, home-based action with global impact.
Don’t just clean up—rewild a corner of your yard. ‘Log it, don’t toss it’ and help nature do what it does best.
