Editing 40d:Tree

{{quality|Masterwork|21:20, 26 April 2011 (UTC)}}{{av}}
'''Trees''' can be found on almost any playable map. Depending whether trees are scarce or dense, they can be a great renewable source of [[wood]].  The density of growth is determined by the [[biome]], and those are visible on the pre-[[embark]] screen by hitting {{k|F1}}, {{k|F2}} etc.  Density does not change - there are no climate shifts during game play.

There are many different varieties that grow in various different types of biomes. [[Tower-cap]]s are trees (giant mushrooms, actually) that grow only underground, and are the only ones that do, and then only under special circumstances. The only difference between different types of trees is the (usually very minor) difference in the weight of the log or item produced - otherwise all trees are identical, equal in usefulness and value.*

:''(* Note that [[preference]]s can alter a dwarf's perception of the value of items made from a type of wood that they prefer.)''

Viewed on their same [[z-level]], many different sub-types of trees have their own symbol, such as {{tile|♣|2:0}}, {{tile|♠|2:0}}, {{tile|¶|2:0}}, {{tile|╞|2:0}} or {{tile|⌠|2:0}}.  Some share the same symbol, but since the only difference is for preferences, this is not a significant problem.  (See table, below, for tree/symbol pairs.)  For most purposes, a tree is a tree.

Trees viewed from one z-level higher look like coloured rectangles ( {{tile|■|2:0}} ), appearing identical to coloured [[block]]s floating in the air. Deciduous trees will change colour to red or yellow in [[autumn]] ( {{tile|♣|4:1}}, {{tile|♠|6:1}} ), and lose their leaves in [[winter]] ( {{tile|╞|6:0}} ).  This does not affect their usefulness - they may be cut down in any season, and produce the same end result.

Trees are not a source of food or other material, so it is not possible to harvest mangos, maple syrup, nuts, rubber, etc.

===Harvesting / Removing the barrier===
Trees are a type of [[map tile]] that form a solid barrier, like [[stone]] or [[ore]].  Trees (but not saplings) will block movement, and prevent designation of [[channel]]ing, [[wall]]s and other [[construction]]s.  [[Caravan]]s are especially vulnerable to being blocked by trees, since they require a path 3-tiles wide.  Trees do not form a floor on the level above them - creatures cannot walk "on top of" trees.  However, a dwarf dropped on top of a tree will remain on top of (1 z-level above) it unless there is a neighboring surface on the same z-level for him to step off onto.  Fired ammunition (arrows, bolts, &c.) will sometimes get 'stuck in a tree' in this fashion as well.

They must be designated for removal from the [[designations|{{Key|d}}esignations menu]] chop {{k|t}}rees, which will instruct [[dwarves]] with the [[Wood cutter|woodcutting]] [[labor]] enabled to grab an [[axe]] and begin chopping down the tree. Once cut down, they become one [[wood|wood log]], which is movable and can be hauled by enabling the Haul Wood labor on any dwarf and designating a wood [[stockpile]].

Trees ''will not'' as of yet be destroyed by [[magma]] or [[fire]] (nor will [[water]] damage them in any way). Saplings can 'drown' in [[water]] and [[magma]], though.  [[Ballista]] arrows can destroy trees, but [[catapult]] stones will not.

Under certain circumstances items can wind up "on top" of trees (1 z-level above the tree).  This occurs when an arrow reaches its maximum range above a tree and then falls onto it, an enemy (or part of one) flies onto the tree, or when any item is otherwise dropped directly above the tree.  As dwarves cannot walk on trees, the only way to recover these items is to cut down the tree.

====Trees and ramps====
Digging a ramp underneath a tree will cause a [[cave-in]] - but the tree will be removed. The tree will not leave a log behind. This is not true of saplings.

===Tree growth===
Trees grow from '''saplings''', which start growing randomly on tiles of a suitable biome. Saplings can be killed by heavy [[traffic]], and also flooding.  Dead saplings will remain for some seasons, and then disappear - or heavy traffic will trample them away.  To grow from a sapling to a tree takes only 3 months and 16.8 days. Trees do not need to be (and can't be) "planted" - even if a map is stripped of all trees, new saplings will regrow, randomly and in their own time. Sadly, the [[elf|elves]] do not seem to comprehend this.

Saplings will not grow to maturity if their tile contains an item or building (including stockpile designations), though removing the item may cause the tree to spontaneously grow up. Paved [[road]]s and [[farm plot]]s periodically purge all terrain features below them, preventing trees (or shrubs) from growing in unwanted areas. Trees cannot grow on stairs or ramps, making it possible to keep trees out of your plumbing by using {{K|u}}p stairs instead of {{K|d}}igging (this does not reveal the tile above). Above-ground trees will only grow in areas where there is sufficient soil in a 3-tile radius beneath them (depending on the local vegetation density ''and'' the quantity of other plants nearby); [[Tower-cap]]s work the same way, but they also benefit from muddy tiles in a 3-tile radius on the same Z-level.

A given [[Region|area block]] has a limit of "things that can grow on it" - and trees and shrubs compete for this when that maximum is reached.*  Removing shrubs will allow more trees (and shrubs) to be able to grow.  A downside to removing these shrubberies is that most of the saplings in the area will be trampled in the process unless they are marked as low-traffic or restricted areas first, a slightly time-consuming process.

:''(*Tower-caps (and underground shrubs?), on levels below the first "above ground" level, do not seem to count toward this limit.)

==Elven Diplomats==
[[Liaison#Elven|Elven diplomats]] eventually come to talk about the "tree situation" in your fort.  Sometimes the diplomat will arrive and merely complain but most often the diplomat will want to set a limit to the number of trees <s>butchered</s> harvested to <s>feed</s> fuel your <s>earth blighting death machines</s> industry.  This quota is based on all the logs you have in your stocks, '''no matter what the source.'''  It doesn't matter if you have a [[Tower-cap]] farm or if you import all your wood; if you have any wood in your stocks, the <s>treehuggers</s> elves will complain.

In version 0.28.181.39a and earlier, trees gained names near [[elf|elven]] settlements. It is unclear what effect this had on gameplay, if any at all.

==List of Trees ==
Above-ground trees marked as "Wet" will only grow within 2 tiles of a natural River or Murky Pool, while those marked as "Dry" will only grow if there is ''no'' river/pool within that range.
