Grass is a natural Template:L that is found in any biome that supports vegetation. It can grow on most Template:L Template:L. It tends to grow quickly, as can be found by channeling an outdoor area. Its growth can indicate the impending growth of a tree. As dwarves and other Template:L walk over it, they have a chance (determined by the value of the Template:L token) of eroding it down to the base soil, on which trees and plants cannot grow. Elves have grasstrample 0. Dwarves have default grasstrample. Dragons have grasstrample 50. A mess of dwarves milling about your entrance will wear away all the grass eventually. A dragon does it with every step.

Template:L and Template:L, tiles similar to grass, appear in Template:L biomes; they will grow on underground soil and Template:L floors after any Template:L has been breached. Livestock feed on them like they do normal grass.

Livestock

Livestock require a steady diet of grass in order to avoid starvation. As they eat, the grass is eroded as though it were trampled, gradually depopulating their Template:L if it isn't large enough. As there are at most 4 bunches of grass per tile, grass that is consumed in the process of an animal grazing means that the base layer of soil is revealed until the grass grows back. There is currently no known way of determining how many of the maximum of 4 bunches of grass are present in any one tile.

Sand and clay

Grass growing on a soil Template:L of Template:L or Template:L will prevent the raw material from being Template:L for the Template:L or Template:L industries. If grass has grown on a collection Template:L you can easily clear it by designating a dirt Template:L (b O) on top of it. A floor Template:L can be placed over a collection activity zone to prevent grass from growing while still allowing the raw material to be collected.

Fire

Grass can also be destroyed by Template:L and Template:L. Creatures such as Template:Ls can shoot fireballs when attacking, and said fireballs can set the grass on fire. If grass ignites, the fire will slowly spread to all connected grass, generating smoke as it burns. Fire turns grass into ashes, but not Template:L. Anything that is flammable and stands on burning grass (if you look at it you will see "A fire") has a chance to catch fire each turn. Note that fire breath (as also used by dragons) will not set grass on fire, instead instantly turning it into ashes. Grassy Template:Ls will not catch on fire, thus preventing the fire from spreading across Template:Ls.

Variation

During a Template:L, grass tiles on the screen change into dry grass tiles, but the effect is purely cosmetic. Also purely cosmetic, the Template:L file contains [VARIED_GROUND_TILES:YES]. If you don't like the grass looking like ,.`', try setting this to NO. The ground will turn into periods only.

The wormy tendrils and staring eyes of Evil Grassland

In Template:L biomes, you may find grass made up of Template:Ls and Template:Ls. It acts just like regular grass for the Template:L that eat it. Wormy tendrils tend to wiggle constantly and staring eyeballs will blink from time to time.

In evil biomes that are also undead areas, much of the grass is dead, like the trees. Animals will not eat the dead grass. Assign a larger area for pastures so grazers can eat the patchy still-living grass.

In Template:L biomes, you may find grass made up of Template:L and Template:L. Like their evil counterparts, they feed Template:L normally.
