Trees

Trees are a terrain feature in Dota 2. They make up a large amount of the map, and are very prominent in the Forests that separate the Lanes. Trees block vision and are impassable, except in certain gaps, or Juke Paths.

Mechanics
Trees cannot be targeted by normal attacks, and can only be destroyed by certain skills, such as Beastmaster's Wild Axes. Trees will regrow five minutes after they were destroyed except if a Hero is standing where they would spawn.

Trees can also be targeted with a Tango in order to eat one. Eating a tree restores Health over time, consumes the Tango, and destroys the tree. Trees can also be destroyed by a Quelling Blade.

Tree Related Skills
Several Heroes have Skills that require or utilize Trees.
 * Nature's Prophet can create Trees and use them to produce Treants. His Sprout ability will spawn a ring of trees around the target area, useful for trapping enemies. He can also convert Trees, including those produced by Sprout, into Treants with his Nature's Call power.
 * Windrunner's Shackleshot ability will shackle a unit to a tree that is behind it, increasing the duration of the stun.
 * Timbersaw's Whirling Death will deal pure damage if a tree is in the area of effect. Timber Chain is a Blink ability similar to Hookshot that can only be casted on trees.
 * Treant Protector's Nature's Guise will make the target unit invisible as long as it stays near a tree.
