Minecraft Mangrove Swamp Seeds
By the ChunkScan Team · Updated August 2026
Mangrove swamps are the humid, tree-tangled wetlands added in Minecraft 1.19 — the only place to gather mangrove wood, mud, and the frogs whose lights power froglight builds. They are also where tadpoles grow, so a swamp near spawn is the fastest way to collect all three frog colours. The seeds below each have a mangrove swamp close to spawn, verified against a scan of over 1.7 million worlds. Every listing is real scan data, not a hand-picked guess.

Why start near a mangrove swamp
Mangrove wood and roots give a distinct red-brown building palette, mud converts to mud bricks and packed mud, and the swamp is the home of frogs and tadpoles — the only source of froglights, one of the brightest and rarest light blocks. Bring a bucket for tadpoles and you can breed all three frog variants by moving them to different biomes.
How the seeds are verified
Each seed was generated and scanned with cubiomes, so the biome layout near spawn matches your world exactly for the listed edition and version. We record which biomes fall within the scan radius of the spawn point, which is how these seeds are known to have a mangrove swamp close by rather than thousands of blocks away.
