TFC Regrowing Forests
by Verph
TFC Regrowing Forests lets forests that TerraFirmaCraft generates slowly spread and regenerate over time, with new trees appearing as the seasons change.
What it does
Trees in the world spread seeds during fall, and the saplings that grow from them are ready the next spring. Trees only spread when the conditions allow it: the mod checks the surrounding environment, climate, groundwater hydration and season before a new tree can appear. Fruit trees and fruit bushes from TerraFirmaCraft take part in the spreading as well, so orchards can come back after being cut down.
The spreading rules are set in a data pack, which covers how fast forests regrow, how far seeds travel and the chance of each spread. The default values are permissive, and a regrowth recipe only needs leaves and a sapling; any other field can be left out, or added to limit growth to specific conditions, such as oak trees that already grow in the TerraFirmaCraft generation rules. The mod depends on TerraFirmaCraft and supports ArborFirmaCraft out of the box.
Files are published for Forge and NeoForge across three release versions, 1.20.1, 1.21 and 1.21.1. Because the mod changes world generation, it must be installed on both the client and the server. The code is under the BSD 2-Clause License and is not open source.
Key features
Gradual forest spread
Forests spread slowly across the world, and the spread continues after the world has been generated.
Seasonal seeding
Trees drop seed-bearing fruit in fall, and new trees grow from those seeds in the next spring.
Climate and groundwater checks
Spawning reacts to climate, season, groundwater hydration and the surrounding environment.
Data pack configuration
Recipes set the regrowth rules, including spread chance, spread distance and the conditions required for regrowth.

What the author says
This mod makes the forests in TerraFirmaCraft regenerate or spread over time. Trees only spread during fall, as this is when they typically drop their seed-bearing fruits, as such new trees will be ready for the next spring. Which trees that can spread or regenerate is configurable using a data pack, as well is how…
