Regrowth

Exclusive to:
Regrowth is a mechanic in Don't Starve Together. There are four main mechanisms for regrowth, which work slightly differently: Regrowth, Offspring Regrowth, Desolation Regrowth, and Resource Renewal. Only the first three are configurable. On the World Customization Screen, the regrowth setting sets a multiplier on how quickly each of these regrowths happen (from Very Slow to Very Fast, 0.15, 0.33, 1, 3, 7). For all types of regrowth, it only decreases the timer for the regrowth time while that entity is in its regrowth season. For example, desolation regrowth time for a Blue Mushtree is 50 days, and their season is Winter, so it will only try to spawn once every 3.33 winters.

Regrowth

After one of these entities is destroyed, the game will try to place a new one after the regrowth time has passed. The game picks a point within 5 tiles of the original spot. It must meet certain conditions, including: the same terrain type, plantable, not on a road, has no entities within 3 units, and no structures/walls/regrowth blockers within 5 tiles. If a player is within 19.2 tiles, it waits (retries every ~29 s) without resetting the full regrowth timer; if a placement check fails, it resets the full regrowth timer and tries again after another period.

Entity	Regrowth Time	Regrowth Condition / Season
	12.5 days	Not Winter or night.
	30 seconds	While the ground is very wet, but not during rain, night, or Winter. Double rate during Spring.
	5 days	Summer.
	9.375 days in Autumn. 18.75 days in Spring.	The base timer is 9.375 days. Paused during Winter and Summer. Slowed by 50% during Spring, meaning it takes twice as long.
	5 days	Any time.
	5 days	Spring.
/	20 days (base timer)	The base timer is true for Autumn and Spring. Paused in Winter. Twice as fast in Summer. Slowed by 20% during Rain.
	5 days	Not affected by seasons, weather, or time of the day.
/ /	20 days (base timer)	When destroyed (dug up or burnt). Regrowth is twice as fast at certain times: Red at Day, Green at Dusk, and Blue at Night.
	12.5 days	Only when planted form burns. Not affected by seasons, weather, or time of the day.

Note that although flowers do not regrow during the rain, new flowers still spawn during rain like they do in single-player Reign of Giants.

Offspring Regrowth

This is intended to give the effect of forests growing and reclaiming land. Each tree has a timer after which it will try to spawn a sapling of the same type nearby. If there are fewer than 5 other trees of the same type in the radius that would have 5 such trees at worldgen, then it will succeed in spawning one. Offspring Regrowth doesn't occur within a 2-tile distance of structures, or around a 0.75-tile radius of any object.

	3 days	Not Winter.
	8 days	Any season.

Desolation Regrowth

Desolation regrowth is intended to spawn trees in areas they belong in after the area has had all or almost all of its trees destroyed, such as by an out of control forest fire. Desolation regrowth cannot occur if there are any of the same type of tree within a 12.5-tile radius, and base structures or walls within 5 tiles, or any entities at all within 3 units (almost a tile). The regrowth will start in their sapling stage (except for Mushtrees, which are immediately Mushtrees).

Resource Renewal

Resource Renewal is a mechanic limited to Wilderness and Endless game modes and is intended to guarantee that essential resources are available for spawned-in players. There are 4 groups of resources, usually with multiple prefabs. Periodically (every ca. 15 minutes) the game checks an area around spawn points (these are used to respawn players in Wilderness mode, and are actually fixed in place during world generation, and present in all game modes). If none of the matching prefabs are found within a 60-unit (15-tile) radius around the point, the game attempts to spawn a randomly-picked prefab from the spawn set. This will only succeed if there are no players within a 240-unit (60-tile) radius of the spawn point. On the surface, spawn points are plentiful in Grasslands and rare in Forest biomes. In the Caves, spawn points are placed only at the cave exit staircases.
