Keystone Species in all Main Biomes!

Keystone Species keep ecosystems alive so I think they deserve to be in Minecraft! Here are my suggestions and explanations for species!

Forests - Squirrels, spread trees seeds

Jungles - Hummingbirds, Tapir, and Agoutis! Hummingbirds: pollinate most flowers in Jungles. Tapirs and Agoutis: Transmit seeds

Mountains - Wolves, here would prevent overpopulation

Deserts - Desert Tortoises: Dig burrow homes that other animals use once they leave

Swamps - Eastern Newts: Control populations in swamps

Savannahs - Elephants: Dig up water and make paths in forests for other animals!

Badlands - Prairie Rodents: Loosen soil so new plants grow while also being a key prey animal

Beaches - Sand Crabs: Prey for many other beach animals!

Stone Shores - Ochre Sea Stars: Keep seaweed populations in check! 

Rivers - Beavers: Break down dead trees near rivers, which lets new trees grow. Also, their dams make pond life flourish!

Oceans - Sea Otters and Manatees! Sea otters: Eat urchins that would otherwise destroy kelp forests. Manatees: Eat overgrown vegetation

Keystone animals already in game are Taiga wolves and salmon, Plains cows, Cherry Blossom Grove’s bees, and Snowy Tundra’s arctic foxes!
