What is Sustainable Firewood?

When you buy or collect firewood there are a number of things to check to make sure it is sustainable. 

  – Is it legal to take the wood from the site?

  – Has the tree naturally died and fallen over? 

  – Are there replacement saplings nearby?

  – Are there other homes for wildlife?

  – Is there other dead timber on the ground to stop soil erosion?

 – Has the nutrient rich bark been left?

To assist in being able to assess how much firewood you can take from different types of woodland please click on the following:  Firewood collector package 

Dead tree on the ground partly cut for firewood
A fallen tree is partly cut for wood and the rest is left on the ground. Only take wood from naturally fallen trees.
A new sapling growing
New saplings are growing to replace dead trees.
A lizard sitting on fallen wood
Fallen timber is used as homes for animals such as this lizard as well as soil nourishing insects and fungus.
Parts on dead tree in gully that has prevented erosion
Fallen timber left in gullies will help prevent erosion by slowing down the flow of water.
Breakdown of nutrients
A tonne of firewood would return these nutrients back to the soil.
Nutrient rich bark left on a fallen log.
Nutrient rich bark left on a fallen log can return to the soil

The table below shows how many meters of Course Woody Debris ( diameter of wood is >10cm) should be left lying on the ground. You should only take wood if there is more than this available at this site.

It is also important to make sure your wood is dry. This also means keeping it covered once you have bought it home.

Keeping your wood covered ensure it burns more effectively.

Your wood heater should also be in good condition. Not only does that mean your wood burns more effectively but is also important for safety. Every year you should have your flue cleaned and checked. The seal around the door should also checked replaced if getting old.
