Swamp Expansion
Swamp Expansion, a Forge world generation mod, reworks swamps with new foliage, creatures, a wood type and blocks for 1.14.4 and 1.15.2.
What it does
Swamps gain new foliage, a cattail plant and large mushrooms, and a new wood type replaces the swamp oaks. Mud pools and mud bricks give the biome its own building material. Villages and witch huts appear in swamp areas, and slimes spawn among them. Buzzier bees and a new creature called the Slabfish add to the biome's population.
The Slabfish can be used as a companion that carries items in a backpack, which lets players store things while they explore. The author notes that the mod was discontinued and that its content was later merged into Environmental, so the project has no further updates. Blueprint is required and must be installed alongside the mod. Servers that run it need every player to install it too. It is published only for Forge, for 1.14.4 and 1.15.2, with 1.7.3 for 1.15.2 as the latest file, under a custom license that is not open source.

Swamps + is a Forge mod for 1.20.1 that is client and server and is not open source, under All rights reserved. The Wetlands is also Forge for 1.20.1, client and server, under All rights reserved. Bayou Blues covers only 1.16.5 on Forge and stays under All rights reserved, so it is the older option for that version.
