Trees are plants in Factorio. They can be mined for raw wood, and are the only source of it. Trees are obstacles to construction and must be cleared to provide building space, but they also reduce pollution, so take care not to remove more than necessary. Currently, trees cannot be replanted.

Destroy 100 trees by impact.

Destroy 10k trees with fire.

Good methods to remove trees

(*) Usable to collect raw wood. Dead trees will give 2 raw wood and have a mining time of 1. Live trees will give 4 raw wood and have a mining time of 2. All other methods just destroy the tree and wood.


A forest fire spreads rapidly after a few moments.

Trees can be set on fire by flamethrowers and flamethrower turrets. The fire will spread from tree to tree, releasing high amounts of pollution and leaving stumps and charred trees behind.

Once on fire, trees cannot be extinguished, but the spread of the fire can be limited by creating a fire break.

Pollution removal

Trees remove small amounts of pollution in their area. After absorbing more than 3500 units of pollution, trees start to lose their leaves, absorbing pollution in the process. The less dense the leaves, the less pollution the tree absorbs. The initial leaf density is influenced by the richness settings during map generation. The higher the richness, the higher the overall leaf density.
