Log

A log or stem is a naturally occurring block found in trees or huge fungi, primarily used as a building block, and to create planks, a versatile crafting ingredient. It comes in nine types: oak, spruce, birch, jungle, acacia, dark oak, mangrove, crimson and warped.

A stripped log or stripped stem is a variant obtained by an axe on a log or a stem respectively. Once stripped, it cannot be reversed.

Breaking
Logs and stems can be broken by hand, but using an axe speeds up the process. Logs and stems drop themselves when broken with any tool.

Trees
Logs generate naturally as part of trees.

Huge fungi
Stems generate naturally as part of huge fungi.

Structures



 * Oak logs generate as part of houses in plains villages, and as supporting beams of swamp huts and normal mineshafts.
 * Stripped oak logs generate in plains villages.


 * Spruce logs generate as part of houses in taiga and snowy plains villages.
 * Stripped spruce logs generate in snowy plains villages.
 * Stripped spruce logs generate in snowy plains villages.


 * Acacia logs and stripped acacia logs generate as part of houses in savanna villages.
 * Acacia logs and stripped acacia logs generate as part of houses in savanna villages.


 * Dark Oak
 * Dark oak logs can generate in pillager outposts as a pile of logs, and as part of watchtowers. They also generate as supporting beams badlands mineshafts.
 * They are also generated in woodland mansions in the walls and borders and in ancient cities.


 * Mixed
 * Oak, spruce, jungle and dark oak logs generate as masts in shipwrecks.
 * Stripped logs also generate as masts in shipwrecks.

Logs and stems
Trees can also be grown using saplings and huge fungi can also be grown using small fungi.

Stripped logs and stems
an axe on a log or stem turns it into a stripped log or a stripped stem, which act the same as regular logs.

Further crafting
The following table presents the amount of logs or stems needed to produce an even multiple of a given item with no waste left over, and the quantity produced (Planks are assumed to be crafted from logs or stems rather than wood or hyphae blocks) (Charcoal are assumed to be crafted from logs rather than wood blocks):

Fuel
Logs, but not stems, can be used as a fuel in furnaces, smelting 1.5 items per block.

Cocoa Beans
Cocoa beans can be placed on the side of both jungle logs and stripped jungle logs to grow a new cocoa pod.

Note blocks
Logs and stems can be placed under note blocks to produce "bass" sounds.

Data values
$$, oak, spruce, birch, and jungle log and wood have the ID name  and are further defined by their block data or block state. Acacia and dark oak log and wood blocks have the ID name  and are further defined by their block data or block state.

Note that when a log or stem is placed, it changes its facing parameters, placing in the direction relative to the block it is placed on.

Logs and stems consider only the axis; a sideways log or stem placed while facing north does not have a top texture rotated 180 degrees from a log or stem placed south.

Trivia

 * In Bedrock Edition, dark oak and acacia logs share a block ID separate from the old logs, called log2, because all the other data values on the previous log block were occupied by rotated variants (red sandstone slabs suffered a similar fate). There are still 8 remaining data values on the block that cannot be obtained. This was also the case in Java Edition prior to 1.13.
 * Even if stems or their plank variants cannot be used as fuel or made into charcoal, the player can bypass this by crafting them into crafting tables or sticks, which can be used as a fuel.
 * Crimson and Warped stems are the only logs that have an animation.
