This small mod makes minecraft leaves decay much faster. It should also be compatible with most modded leaves. If you don’t like the default speed you can also change the decay speed & fuzz (How “random” the decay will be) in the config file.

This mod is not required client side so clients don’t need to have the mod installed on a server.
