Editing 40d:Tree

Viewed on their same [[z-level]], many different sub-types of trees have their own symbol, such as {{tile|♣|#070}}, {{tile|♠|#070}}, {{tile|¶|green|black}}, {{tile|╞|green|black}} or {{tile|⌠|green|black}}.  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|█|#070}} ), appearing identical to coloured [[block]]s floating in the air. Deciduous trees will change colour to red or yellow in [[autumn]] ( {{tile|♣|#f00}}, {{tile|♠|#ff0}} ), and lose their leaves in [[winter]] ( {{tile|╞|#770}} ).  This does not affect their usefulness - they may be cut down in any season, and produce the same end result.

Trees are currently{{version|0.28.181.40d}} not a source of food or other material, so it is not possible to harvest mangos, maple syrup, nuts, rubber, etc.

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.

They must be designated for removal from the [[designations|{{Key|d}}esignations menu]] chop {{k|t}}rees, which will instruct [[dwarves]] with the [[woodcutting]] [[labour]] 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 the Haul Wood labour on any dwarf and designating a wood [[stockpile]].

Under certain circumstances arrows 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, or an 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.

Digging a ramp underneath a tree will cause a [[cave-in]] - but the tree will be removed. This is not true of saplings.

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 about a year and a half or more, though this seems randomized to some degree. 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. <!--Which is why those elves need to quit bitching about our timber industry.-->

Saplings will not grow on a tile with items on it (such as stone, food, etc). Saplings will not grow where a road has been laid down. Saplings will appear but not grow into trees if there is a layer of stone under the top-layer of soil under them, or if the soil has been dug out from beneath that top layer.*

[[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.

Trees also gain names near [[elf|elven]] settlements. It is unclear what effect this has on gameplay, if any at all.
