Biomes are the natural environments that Planet Zoo 2 uses to set up each animal's home. The game splits them into land biomes, such as Grassland, Tropical, and Tundra, and water biomes, such as Reef and Mangrove. Each biome has its own ground, plants, and climate, so matching the right biome to an animal is the first step to keeping it healthy.

How Biomes Decide Where an Animal Can Live in Planet Zoo 2
Each animal lists the biomes it can live in, and its habitat has to suit one of them. The game checks the habitat itself, too. Biome-specific terrain and foliage are part of that check, so the ground and plants you build are how a habitat shows which biome it belongs to.
Animals are used to particular ground, plants, and temperatures, and they settle best when the habitat gives them those. Every species has preferred plants listed in its Zoopedia entry, and having enough of them is what makes the habitat read as the right biome. Temperature is checked along with terrain and plants.
What Happens When an Animal Is in the Wrong Biome
Welfare is the first thing to take a hit. An animal in a biome it doesn't accept loses welfare steadily, so a tropical animal kept in a temperate habitat slowly declines. If the mismatch isn't fixed, it can start a chain of welfare losses that ends in a red welfare icon. Low welfare can also push an animal to try to escape.
When an animal's welfare drops, start with its welfare panel. Find the need that isn't being met, then look at the habitat for the cause. It's better to fix that than to copy a habitat design from another species, since each species has its own needs.
Which Animals Can Share a Habitat
A shared biome is a starting point, not proof that two animals can live together. The habitat also has to meet the needs of every animal in it, and those animals have to be compatible with each other. Mixing animals that aren't compatible can start fights.
Water Biomes, Aquariums and Aviaries
The water biomes are Reef, Lakes and Rivers, Estuarine, Open Sea, and Mangrove. Fully aquatic animals live in aquariums, and the water type has to match each animal. Lakes and Rivers animals need freshwater, most sea and reef animals need saltwater, and a few species need brackish water, which sits between fresh and salt, so check each animal's salinity before you fill the tank.
Flying birds follow the same biome rules, and they need covered, netted habitats so they can use their wings. Aviaries are built from barriers, support poles, and mesh covers.
Biomes and Wildlife Reserves
Each wildlife reserve is tied to a biome, and that biome decides which animals can be released there. A Grassland reserve won't accept the same species as a Taiga one, so check the biome before you plan a release.
FAQ
Can an animal live in more than one biome?
Yes, and many do. The Greater Flamingo, for example, is listed for Estuarine, Temperate, and Wetlands, which gives you more than one way to house it.
How do I set an aquarium to saltwater or freshwater?
Salinity is set on the filtration network, not on the tank. Select the Water Filter, open Edit Filtration Network, and choose Freshwater, Brackish or Saltwater. Each network runs one water type, so tanks with different salinities need separate filters, and a saltwater animal such as the Blacktip Reef Shark loses welfare right away in the wrong water.
What does an animal need before it can be released into a wildlife reserve?
The reserve has to be ready first. The right habitat type must be established there, and there has to be enough food for the animal. The reserve also needs to be able to support the animal's survival, which comes before anything else.
Where do I check which animals can share a habitat?
The Zoopedia has a Zoo Habitat tab with Thriving and Neutral relationships for each species. Thriving pairs point to a stronger fit and can give a bonus, while Neutral pairs tolerate each other without one. A species' relationships appear once you have researched it.
