'''Trees''' are plants in Factorio. They can be mined for [[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.

== Good methods to remove trees ==

* Mining by hand (*)
[[File:Big-tree-2.png]]
* Shooting swaths of trees with a [[shotgun]] or [[combat shotgun]]
[[File:Dead-tree.png]]
* Using [[grenade]]s to blow them up
 
== Good methods to get rid of trees ==
 
* Mining with [[Iron axe|Iron]] or [[Steel axe|Steel]] axes (*)

* Using [[Poison capsule|poison]] to kill them
* Using [[Poison capsule|poison]] to kill them

* Knocking them down by driving a [[tank]] over them
* Burning them with a [[Flamethrower]]
* Burning them with a [[flamethrower]], causing a forest fire
 
* Burning them with a flamethrower while in a tank
<small><i>(*) Usable to collect raw wood. All other methods just destroy the tree.</i></small>
* Using [[atomic bomb]]s to blow them up
 
There are more methods, but these have a good ratio of 'tech vs. trees per minute'.


== Collecting Wood ==
<small><i>(*) Usable to collect wood. Dead trees will give 2 wood and have a mining time of 0.5. Live trees will give 4 wood and have a mining time of 0.55. All other methods destroy both the tree and the wood.</i></small>


Raw wood can be collected by chopping down a dead or live tree. 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.
== Fires ==
[[File:ForestFireBegins.gif|frame|A forest fire spreads rapidly after a few moments.]]
Trees can be set on fire by [[flamethrower]]s and [[flamethrower turret]]s. The fire will spread from tree to tree, releasing high amounts of [[pollution]] and leaving stumps and charred trees behind.


Although collection of raw wood is easy to do, there is currently no way to completely automate the collection of raw wood, or replant it.  However wood processing is planned, as discussed [http://www.factorioforums.com/forum/viewtopic.php?f=9&t=128 here].
Once on fire, trees cannot be extinguished, but the spread of the fire can be limited by creating a [[wikipedia:Firebreak|fire break]].


== Pollution removal ==
== Pollution removal ==


Trees remove small amounts of pollution in their area. The pollution caused by a [[Stone furnace]], for example, can be removed by sixty live trees.
Every single tree absorbs a small amount of pollution in its chunk per second. If the total pollution in a chunk is above 60 units, once per second some of the trees in that chunk each have a chance to either lose one stage of leaves or have their leaves become one stage more gray. Regardless of whether the tree loses leaves or gets grayer, 10 pollution are absorbed by the tree.<br>
A tree stops losing leaves/becoming more gray once the sum of its gray percentage and its leaves lost percentage is above 120%. 50% of trees stop their leaf progression one stage earlier. As the grayness and leaf stage are then locked for that tree forever, it is possible for trees to keep some leaves in heavily polluted chunks but in turn be very gray, or the other way around.<br>
The less dense the leaves, the slower the tree absorbs pollution, however tree grayness does not affect pollution absorption.

Good methods to remove trees

(*) Usable to collect wood. Dead trees will give 2 wood and have a mining time of 0.5. Live trees will give 4 wood and have a mining time of 0.55. All other methods destroy both the tree and the 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

Every single tree absorbs a small amount of pollution in its chunk per second. If the total pollution in a chunk is above 60 units, once per second some of the trees in that chunk each have a chance to either lose one stage of leaves or have their leaves become one stage more gray. Regardless of whether the tree loses leaves or gets grayer, 10 pollution are absorbed by the tree.
A tree stops losing leaves/becoming more gray once the sum of its gray percentage and its leaves lost percentage is above 120%. 50% of trees stop their leaf progression one stage earlier. As the grayness and leaf stage are then locked for that tree forever, it is possible for trees to keep some leaves in heavily polluted chunks but in turn be very gray, or the other way around.
The less dense the leaves, the slower the tree absorbs pollution, however tree grayness does not affect pollution absorption.
