Dead trees are part of the forest

Decaying trees are left in the forest as they offer food and habitats for micro-organisms. Other organisms that benefit from decaying wood include mosses, fungi, insects and insect-eating animals. The sturdy dead trunks of all tree species, whether standing or lying on the ground, are valuable for nature and biodiversity. 

The trees found on the ground, whatever their condition, must be left where they are in city-owned forests and should not be collected for firewood.

Before any wood is used as firewood, it must first dry out for one year. When burned, damp decaying wood produces very little heat. Burning damp wood also generates large quantities of particulate matter, which is harmful when inhaled.
