Rarity of biomes in Minecraft Java 1.15.2

After my first batch of 50.000 maps, i decided to check the rarity of all 66 biomes across the screenshots i got. Those information were taken from Minecraft Java 1.15.2 with 5K square maps, so going from -5000 -5000 to +5000 +5000. It’s a first approach to help me get an initial idea of what are the rarest biomes, to exclude some of them later and still get great seeds.

As you can see, the rarest biome is Jungle Edge M, this biome was present on less than 2.000 maps out of 50.000 maps. Right after, we have Mesa Plateau M and Mesa Plateau F M, but still 4 to 7 times more than Jungle Edge M. Here is what we can learn about that biome on Gamepedia :

The extremely rare Modified Jungle Edge variant generates only in strict conditions, and is the rarest biome in the game, covering only a few millionths of the Overworld by area (the very rare Mushroom Fields biome covers about a thousandth, for comparison). In order for modified jungle edges to generate, a Swamp Hills biome must generate right outside the edge of the jungle. This results in a double-layered transition, with a thin normal Jungle Edge bordering the swamp hills, and the modified jungle edge bordering the jungle. As both jungles and swamp hills are already rare, and even more rarely do they generate bordering each other, the conditions for a modified jungle edge to generate are extremely rarely met. When they actually do manage to generate, they are often just a few hundred blocks in length, making them one of the smallest biomes as well. Modified jungle edges feature the same smooth transition and lowered tree density that regular jungle edges have, though with more mountainous terrain and occasional overhangs. Ocelots, parrots, and pandas may spawn in this biome, but jungle pyramids do not generate here.

When searching for the best maps, i won’t always take into consideration the two last biomes : Jungle Edge M and Mesa Plateau M. Maps with 64 biomes are already fantastic maps, that’s what i usually use them for my resources worlds and keep 66 biomes maps for people to build.

 

Screenshots of Jungle Edge M biome

As you can read from Gamepedia, Jungle Edge M is a very rare biome and often have a small size. While browsing my seeds, i found a map with the biggest Jungle Edge M biome i have at the moment to show you that rare place. I used the seed 6788686509022659189. You have to move to +1700 +3700 to see this biome. The density is 0.04213%, quite enough to have a good view of it. For your information, this is a 58 biomes seed, sadly it miss Mesa biomes, but that’s a good opportunity to see a Jungle Edge M biome. Here are some screenshots of it :

If you like rare biomes and would like to play with some of them, follow my website, i will post some of the best seeds for them later. You can also post requests on my Discord.
