Trees can be found on almost any playable map. Depending whether trees are scarce or dense, they can be a great renewable source of Template:L. The density of growth is determined by the Template:L, and those are visible on the pre-Template:L screen by hitting F1, 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. Template:Ls 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 Template:Ls can alter a dwarf's perception of the value of items made from a type of wood that they prefer.)

Viewed on their same Template:L, many different sub-types of trees have their own symbol, such as ♣, ♠, ¶, ╞ or ⌠. 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 ( ■ ), appearing identical to coloured Template:Ls floating in the air. Deciduous trees will change colour to red or yellow in Template:L ( ♣, ♠ ), and lose their leaves in Template:L ( ╞ ). 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 Template:L that form a solid barrier, like Template:L or Template:L. Trees (but not saplings) will block movement, and prevent designation of Template:Ling, Template:Ls and other Template:Ls. Template:Ls 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 Template:L chop trees, which will instruct Template:L with the Template:L Template:L enabled to grab an Template:L and begin chopping down the tree. Once cut down, they become one Template:L, which is movable and can be hauled by enabling the Haul Wood labor on any dwarf and designating a wood Template:L.

Trees will not as of yet be destroyed by Template:L or Template:L (nor will Template:L damage them in any way). Saplings can 'drown' in Template:L and Template:L, though. Template:L arrows can destroy trees, but Template:L 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 Template:L - 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 Template:L, 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.

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.*

(*Template:Ls operate differently, and are not fully understood. See that article for a more complete discussion on their growth requirements.)

A given Template:L 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

Template:L 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 butchered harvested to feed fuel your earth blighting death machines 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 Template:L farm or if you import all your wood; if you have any wood in your stocks, the treehuggers elves will complain.

Trees also gain names near Template:L settlements. It is unclear what effect this has on gameplay, if any at all.
