After Storm Goretti devastated Cornwalls’ tree resource the big clean up began. Health and safety was the first priority but now media coverage is intent on clearing away the fallen trees. Here we question whether this is really necessary and why dead wood is actually a really good thing.

When most people see fallen trees, rotting logs, or dead branches, the instinct is to clean them up. They look messy. Unmanaged. Like something went wrong. But in nature, dead wood isn’t a problem — it’s a feature. In fact, many ecosystems depend on it. When we remove dead wood, we’re often stripping away one of the most important pieces of the system without realizing it.

Dead wood is full of life. It might be dead, but it’s anything but empty. A single fallen log can support hundreds of species over time. Insects bore into it, fungi spread through it, and birds show up to hunt or nest. Small mammals use it for shelter, and amphibians tuck themselves underneath where it stays cool and damp. Some species can’t survive without dead wood at all. Take it away, and they vanish — along with the animals that depend on them.

Dead wood is how woodlands recycle themselves. As logs and branches slowly break down, fungi and microbes get to work, turning tough wood into usable nutrients. Those nutrients seep back into the soil and feed new plant growth. This happens gradually, which is actually a good thing. Instead of a quick nutrient dump, dead wood provides a slow, steady supply that keeps ecosystems balanced over time.

Rotting logs are surprisingly good at holding water – a natural sponge on the woodland floor They soak up rain, reduce runoff, and keep nearby soil from drying out too quickly. During dry spells, that stored moisture can make the difference between seedlings surviving or dying. That’s why young trees sometimes sprout right on top of decaying logs — they’re basically nature’s starter pots.

Dead wood supports life from the ground up – a key food chain constituent. Fungi break it down, insects feed on the fungi and wood, birds and mammals feed on the insects, and predators feed on them. Pull out the dead wood, and that whole chain starts to unravel. This is one reason “tidy” parks and woodlands support fewer species than places that are allowed to look a little wild.

It even helps with carbon storage. When a tree dies, it doesn’t immediately release all its carbon. That carbon stays locked in the wood as it slowly decomposes — sometimes for decades. Some of it ends up stored in the soil long term. Removing dead wood speeds that process up. Leaving it where it is keeps carbon cycling at a slower, more natural pace.

Ecosystems are more resilient with plenty of dead wood and bounce back faster after storms, fires, or pest outbreaks. They offer shelter, moisture, and food when conditions get tough. Landscapes that are overly managed and “cleaned up” tend to be less flexible and more fragile.

So let’s make deadwood centre stage. It may not fit our idea of a neat landscape, but it’s one of the easiest ways to support biodiversity. Leaving a fallen log, a standing dead tree, or a pile of branches (where it’s safe to do so) can make a huge difference.

In nature, decay isn’t failure. It’s how life keeps going.
