No Leaf Decay
by hrudyplayz
Forge mod No Leaf Decay stops leaves on 1.7.10 from decaying, which removes the leaf-decay checks that run when trees are cut.
What it does
Normally, leaves that lose their connection to a log are removed one by one, and each removal is checked on every game tick. No Leaf Decay extends the leaf block class so that these leaves stay in place, and a config file lets the server owner adjust the behavior. The mod is aimed at worlds where large trees in some biomes cause noticeable slowdowns from constant decay checks.
Because the change is limited to how leaves decay, the mod works alongside other mods that add their own block physics, and it does not alter how leaves look or drop items. Installation requires MysteriumLib, which must sit next to the mod on the same Forge 1.7.10 setup. Servers that run it need every player to install it too. Files cover 1.7.10 only, and the current build is 1.0 for 1.7.10, published 2022-09-02 under the MIT License as open source.
Key features
No leaf decay
Leaves stay in place after the logs they grew from are removed, so no decay checks run for them.
Config file
A config file controls the decay behavior, and it patches leaf blocks added by other mods automatically.
Performance in large trees
Worlds with many big trees, such as some biomes, can see less lag because leaves no longer trigger decay processing.
Compatibility

Use cases
Forest-heavy worlds
Players with large forest biomes can keep leaves stable when trees are felled in dense areas.
Server performance tuning
Server owners running 1.7.10 can reduce decay work on tree-heavy terrain using the config file.
Who it’s for: Players and server owners on Minecraft 1.7.10 with Forge who want to reduce lag from leaf decay, and who are comfortable installing a small library dependency.
How it compares
Leaf Culling is a client-side only mod, open source under the GNU Lesser General Public License v3.0 only, and it is published for 1.7.10 only, so it does not change decay on a server. Smart Leaf Decay is server-side only, licensed under the MIT License without open source, and covers Forge 1.16 – 1.19.4, a range that does not include 1.7.10. Fast Leaf Decay runs on Fabric, Forge, NeoForge and Quilt for 26.2 – 26.3, so it is unrelated to this 1.7.10 release.

What the author says
A small mod for Minecraft 1.7.10 that prevents leaves from decaying, that's it. This can greatly improve the performance of the game in some cases. It has no config file and should work fine with any mod that adds leaves (it can automatically patch them). Use this if you suffer from performance issues in some biomes…
