Planet Zoo 2 Release Groups by Animal

What a release group is

Animals leave your zoo for a Wildlife Reserve as a release group. Frontier says the groups range from single animals to breeding pairs and larger groups, depending on the species, and that a group has to meet requirements such as longevity, fertility and genetic diversity. The Zoopedia names six group types. The names fit Frontier's description, from a Solitary Male or Solitary Female to Breeding Partners and the larger Mixed Group and Bachelor Herds, but the Zoopedia lists only the names, not how many animals each group holds, so we do not add sizes here.

Most species list more than one type, so the numbers add up to more than the 104 species with release groups.

The six Wildlife Reserves and their animals

These are the reserves the animal entries name, with every species that lists each one. 37 animals can go to more than one reserve, among them 20 of the 29 grassland animals, which list both African reserves.

Fish and birds you can release

Reserves are not only for land animals. Six water animals list a reserve: African Tigerfish, Blunthead Cichlid, Brown Trout, Clown Loach, Common Rudd and Giant Gourami, all fish of the Lakes and Rivers biome. Ten of the twelve aviary birds list one too: Eurasian Bittern, Golden Eagle, Great Hornbill, Greater Flamingo, Long-Eared Owl, Long-Tailed Parakeet, Secretarybird, Shoebill, White-Backed Vulture and White-Tailed Sea-Eagle. Every reef and open-sea animal, including the sharks, the rays, the Hawksbill Turtle and the West Indian Manatee, lists release group types but no reserve. How much flying space the birds need in your zoo first is on the Planet Zoo 2 flyable area page.

Animals with no reserve listed

These 46 species list release group types, but their entries name no reserve: African Penguin, Blackspotted Puffer, Blacktip Reef Shark, Blue and Gold Fusilier, Bluespine Unicornfish, Boeseman's Rainbowfish, Clown Anemonefish, Clown Triggerfish, Dolphinfish, Galápagos Giant Tortoise, Gharial, Giant Grouper, Giant Panda, Golden Lion Tamarin, Golden Trevally, Goodfellow's Tree-Kangaroo, Great Hammerhead, Grizzly Bear, Hawksbill Turtle, Humphead Wrasse, Indian Ocean Oriental Sweetlips, Indo-Pacific Leopard Shark, Indo-Pacific Sergeant, Javan Green Magpie, Javanese Cownose Ray, Komodo Dragon, Longfin Batfish, Ocean Sunfish, Ocellated Eagle Ray, Pacific Bluefin Tuna, Pacific Sardine, Palette Surgeonfish, Przewalski's Horse, Red Lionfish, Red Panda, Ring-Tailed Lemur, Sailfin Snapper, Sand Tiger Shark, Schooling Bannerfish, Snow Leopard, Threespot Damselfish, Toco Toucan, West Indian Manatee, Western Chimpanzee, Western Lowland Gorilla and Yellow Tang. Frontier's help page says only species that have a suitable Wildlife Reserve can be released, so as of October 19, 2026 there is no reserve to send them to.

Animals without release information

The entries of 32 species show neither a reserve nor a release group type: the 30 exhibit animals, from insects and spiders to frogs and snakes, plus the Bactrian Camel and Koi. Want to know what else a species needs? The Planet Zoo 2 Zoopedia guide shows each animal's habitat and biomes, and the habitat planner compares the checked space and temperature of the animals you choose.
