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.

Achievements

Run Forrest, run Destroy 100 trees by impact.

Pyromaniac Destroy 10k trees with fire.

Good methods to remove trees

• Mining with iron or steel axes (*)
• Shooting swaths of trees with a shotgun or combat shotgun
• Using grenades to blow them up
• Using poison to kill them
• Having construction robots harvest them using a deconstruction planner (*)
• Knocking them down by driving a tank over them
• Burning them with a flamethrower, causing a forest fire
• Burning them with a flamethrower while in a tank
• Using atomic bombs to blow them up

(*) 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.

Fires

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 500 units of pollution in the process. Apart from the visuals, this does not affect the tree.
