Canebrake Biome

Minecraft has had multiple cases of features added to spread awareness for conservation efforts, like Bees in, well, Buzzy Bees or Axolotls in Caves & Cliffs, so for a future game drop why not only add an endangered species but an endangered biome? Here's some features I believe a canebrake biome would add to Minecraft. 

• River Cane, a color variant of Bamboo similarly to how wood has color variants for biomes.
• 5 butterfly species depend on cane, Providing an opportunity to add a mob many people have suggested for the game in a fitting update.
• Venus Flytraps and Alabama Pitcher Plants grow in canebrakes, perhaps acting as a way for people to grow a natural defense for their base, like the wither rose.
