Nature Is Alive
by Itamio
Nature Is Alive changes the world over time, letting stone turn mossy, grass spread onto dirt and forests regrow on their own.
What it does
Blocks in the world decay and change as time passes. Stone placed near water slowly takes on moss, and grass blocks grow up to two blocks tall. Exposed dirt turns into grass, and saplings spawn new grass and grow into full trees, so forests spread further than they do in vanilla. Buildings degrade too: walls, stairs, slabs and other blocks can wear down when left exposed to air.
The mod is a server-side only Forge build for 1.20.1, so only the server needs it and players join without installing anything. It is published under All rights reserved and is not open source. Its main category is world generation, with decoration, game mechanics and utility tags, and the single published file is 1.0.0 for 1.20.1, released on 2025-06-29.
Key features
Moss conversion
Stone close to water gradually becomes mossy, changing the look of ruins and stone structures over time.
Structural decay
Walls, stairs, slabs and other building blocks degrade when exposed to air, so unattended builds weather away.
Grass spreading and spawning
Dirt left open to the air gradually turns into grass, and grass blocks can then sprout tall grass and flowers such as dandelions, poppies and tulips.
Forest regeneration
Saplings spawn grass around them and grow into full trees, so cleared areas refill with forest.

How it compares
The Grass Requiem is a Forge mod for 1.20.1 that both the client and server run, and it is published under All rights reserved. Fast Growth is server-side only for 1.20.1 and open source under the GNU Lesser General Public License v3.0 only, so it is the closer match on the server side.
