Trees are a type of plant. They can either be native to the [[Biome]] or planted by the player in a growing zone. They are vulnerable to fire and leave behind burnt trees when burnt. Cutting them down yields [[wood]], a resource to craft weapons, make [[furniture]], feed the [[wood-fired generator]], and more.  While in real life Cacti and Bamboo technically aren't trees, in RimWorld they are included in this category.

Trees are a type of plant. They can either be native to the biome or planted by the player in a growing zone. Native trees are immune to blight, and will spawn in as seed from the map edges. Teak and Cecropia are native to Tropical biomes, Oak and Poplar are native to temperate biomes, Cacti and Poplar are native to Arid biomes (only Cacti in Extreme Desert), and Birch and Pine are native to colder biomes (bar Ice Sheet). Cacti are unique in the respect that they won't give a flying hoot as to what ground they happen to grow on; as they have a fertility sensitivity of 0% and minimum fertility of 5%.

Trees that are native to your colony's biome may be planted once [[Tree sowing]] has been researched by growers with a Plants skill of 6+. However, growing Cocoa trees requires further research and may be planted by growers with a Plants skill of 8+.  Trees are different from other crops in that they require at least a one tile distance from other crops as well as each other, including wild trees.  Farmers will automatically cut wild trees for this. Native trees are immune to blight, but cocoa trees are not.

Trees have four types of natural enemies, which fall into two categories. Their natural predator is the [[Thrumbo]] and the [[Alphabeaver]], and some biologists have classified "Fire" as a third type of natural enemy. The other type of enemy are [[colonist]]s, who hunts trees for their [[Wood|wood]]. It is unclear exactly what colonists use it for, but their range of usage reportedly varies from construction material, weaponry and rather sinisterly as food for a [[Fueled generator|fueled generator]]. Humans are by far the biggest threat to trees, their unrelenting hunger for flooring and dining chairs has often been cited as the leading cause of deforestation. Some have had success in taming trees, going so far as to train them to grow in neat rows in intricately designated growing zones. For some bizarre reason; the Saguaro Cactus 'seed' is so elusive that Cacti cannot be grown in growing zones - and no man has ever been known to grow these sacred spiny plants.

Vulnerable trees can be brutally murdered at 40% growth to obtain 50% of their coveted yield. Cacti can be cut at 20%. Note that the Growth Time in the below table assumes 24hr growth. Since trees, as all plants, rest between the hours of 19h and 6h, actual growth time is longer. Also note that environmental factors such as temperature and light levels can further negatively influence growth speed.

== Temperature ==

If the ambient temperature drops below freezing, trees will cease to grow until they return to their comfortable range again (including Pine trees that are native to cold biomes). Some trees will instantaneously shed ''all'' of their leaves at -2°C, while sturdier specimens will hold out until -10°C. This range differs from tree to individual tree. If the temperature remains at a comfortable level for at least a day, their leaves will magically reappear.

Additionally; Humans can also tactically utilise trees as some form of cover, being marginally more effective than hideous [[Debris|Rock Chunks]], but not as effective as rugged [[Sandbags|sandbags]] and sturdy walls. They do this so by standing against the tree trunks and popping off shots, while the opposition rains their lead into the fragile, yet sturdy bark, and also the skulls, organs and limbs of those 'protected'. Alternatively, the mysterious Humans may be moved from tree-to-tree with so-called 'Melee Weapons' (or simply their 'Fists'), until they eventually reach their opponents (or get shot in the process) and hack or bash them to pieces or a pulp respectively while they hopelessly cower, using their very tree as 'cover'.

Trees are a type of plant. They can either be native to the Biome or planted by the player in a growing zone. They are vulnerable to fire and leave behind burnt trees when burnt. Cutting them down yields wood, a resource to craft weapons, make furniture, feed the wood-fired generator, and more. While in real life Cacti and Bamboo technically aren't trees, in RimWorld they are included in this category.

  • Teak, Cecropia, Palm and Bamboo are native to Tropical biomes.
  • Oak and Poplar are native to temperate biomes.
  • Cacti and Poplar are native to Arid biomes (only Cacti in Extreme Desert). Cacti are unique in that they have a fertility sensitivity of 0% and minimum fertility of 5%.
  • Birch and Pine are native to colder biomes (barring Ice Sheet and Sea Ice).
  • Cocoa is not native to any biome.

Ecosystem

Trees are natural food sources for Alphabeavers and Thrumbos.

Farming

This image shows how forbidding floor placement stops incorrect placing of trees. Form a similar pattern in a growing zone and marvel at the sudden lack of stupidity in your colonists.

Trees that are native to your colony's biome may be planted once Tree sowing has been researched by growers with a Plants skill of 6+. However, growing Cocoa trees requires further research and may be planted by growers with a Plants skill of 8+. Trees are different from other crops in that they require at least a one tile distance from other crops as well as each other, including wild trees. Farmers will automatically cut wild trees for this. Native trees are immune to blight, but cocoa trees are not.

Trees may not be grown under roofs. This means that trees may not be grown in completely closed greenhouses. They may only be grown in greenhouses with roofs open in a grid pattern, that leak a lot of temperature-controlled air.

Colonist have a very annoying habit of planting trees in very inefficient patterns, drastically reducing yield unnecessarily. However, there is a way to stop this without constant micromanagement (see image).

Temperature

If the ambient temperature drops below freezing, trees will cease to grow until they return to their comfortable range again (including Pine trees that are native to cold biomes). Some trees will instantaneously shed all of their leaves at -2°C, while sturdier specimens will hold out until -10°C. This range differs from tree to individual tree. If the temperature remains at a comfortable level for at least a day, their leaves will magically reappear.

Harvest

At 40% growth, it is possible to obtain 50% of their yield. Cacti can be cut at 20%. Note that the Growth Time in the below table assumes 24hr growth. Trees don't grow between 19h and 6h. Note that environmental factors such as temperature and light levels further negatively influence growth speed.

Cover

Trees can be used for cover at 25% efficiency.
