Planet Zoo 2 Wiki
Every system that has a verified page. This hub answers one question fast: which page or tool moves my zoo forward right now?
Planet Zoo 2 released on 13 October 2026 and has already been patched twice. This wiki documents what the game tells you (Zoopedia records, player guides, patch notes) and separates it from what players report. Where a value is only community-reported, the page says so.
Animals and habitats
- Animal database — 136 species with enclosure type, biomes, barrier grade, space, temperature and group limits. Open the table
- By habitat type — terrestrial (57), aquarium (37), aviary (12), exhibit (46). Compare enclosure types
- By conservation role — what a species can contribute to a release programme. See status groups
- Habitats — aquariums, aviaries and exhibits each carry their own build rules. Habitat hub
Care and welfare
Welfare is the system that punishes a small mistake for a long time. The Zoopedia already publishes the numbers that matter, so the wiki turns them into a checklist.
- Welfare and thriving — categories, symptoms, and which value to fix first. Welfare guide
- Research — what research changes and how it gates care items. Research guide
- Breeding and release — the full path from a breeding pair to a reserve release. Breeding guide
Progression and modes
- Accreditation — tiers 1-5, what each unlocks, and the two star systems behind them. Tier table
- Wildlife Reserves — biodiversity stars, ecosystem tools and releases. Reserve guide
- Franchise state — the online side: market, storage, maintenance windows. Franchise overview
- Career and Sandbox — medals versus free build. Career · Sandbox
Tools that use this data

FAQ
Common questions about this topic.
Where should a returning Planet Zoo player start?
Start with the animal database to check a species' barrier and temperature values, then the accreditation page: Franchise progression in the sequel is driven by reputation and biodiversity stars.
Does this wiki cover Planet Zoo (2019) as well?
No. Values here come from Planet Zoo 2 records; the first game uses different habitat logic.
Are community numbers marked?
Yes. Accreditation tier requirements are labelled as cross-checked community values because Frontier said on 14 October 2026 that the requirements are still under investigation.
