Planet Zoo 2 Wildlife Reserve Tracker

A Planet Zoo 2 reserve tracker for every Wildlife Reserve Ecosystem: tick the animals you release and see which Species Roles each Ecosystem still needs before it can flourish.

Last updated Game version: Update 1.0.10 (November 9, 2026)

Quick answer: track all 32 Ecosystems in three steps

  1. Set your mode and tier. Animals you cannot buy yet are greyed out.
  2. Tick what you released under the Ecosystem you released it for. One animal can fill several roles there.
  3. Fill every role. An Established Ecosystem starts Flourishing once all its roles are filled; the box at the top names the animals that fill the most missing ones.

75 roles to fill across four biomes. The Red Deer fills a role in 8 Ecosystems, more than any other animal. Open the tracker · Animals that fill the most roles

Track every Wildlife Reserve Ecosystem

Each card lists one Ecosystem's roles and the animals that can fill them in that biome's reserves. Where a biome has two reserves, an animal that can only go to one of them says so.

Animals that fill the most roles

A role place is one role in one Ecosystem. These ten animals cover the most of the 75, so breeding them for release moves the most Ecosystems forward.

Ecosystems one animal can finish

Four Ecosystems need a single role, so one release finishes them: Watering Hole (Wetland Engineers: the Common Hippopotamus), River (Underwater Grazers: the Giant Gourami), Rocky Peaks (Low Browsers: the Red Deer) and Lake (Temperate) (Underwater Grazers: the Common Rudd). In three more, one animal covers every role on its own: Dense Forest (the African Savannah Elephant, the Masai Giraffe and the Reticulated Giraffe), Montane Forest (Boreal) (the Red Deer) and Lowland Marsh (the Eurasian Beaver). The longest lists have 3 roles, in 15 Ecosystems.

How the tracker counts

The roles on each card are the Species Roles that Ecosystem lists in the game. The animals under a role are the ones whose official Zoopedia page gives that role and a Valid Reserve in the Ecosystem's biome; the tier next to each is when you can buy it in the mode you picked, from our Planet Zoo 2 accreditation tiers. A tick counts for every role that animal has in the same Ecosystem, so the Red Deer ticked once can fill up to two roles there.

Before you release, check the group the reserve accepts: our Planet Zoo 2 release groups page gives every animal's. What each role means, with every animal that has it, is on the Planet Zoo 2 Ecosystem Roles page; the two roles players look for most have their own pages, Low Browsers and Wetland Engineers.

Planet Zoo 2 Wildlife Reserve tracker questions

Is there a Wildlife Reserve tracker for Planet Zoo 2?

Yes: this page is a Planet Zoo 2 reserve tracker. It lists all 32 Wildlife Reserve Ecosystems with the Species Roles each one needs and the animals that can fill them. Tick the animals you release and it shows the roles still missing and which animals fill the most of them. Your ticks stay in your browser.

How do I make an Ecosystem flourish in Planet Zoo 2?

Restore it until it is Established, then release animals that fill every Species Role the Ecosystem lists. Once all of its roles are filled, Frontier’s Wildlife Reserves guide says, it starts Flourishing.

Which animal fills the most Ecosystem roles in Planet Zoo 2?

The Red Deer: it can fill 12 role places in 8 Ecosystems, more than any other animal. It goes to Scottish Highlands, Sweden and Poland, at Career tier 2, Franchise tier 1.

Can one animal fill more than one role in an Ecosystem?

Yes. An animal fills every role its Zoopedia page lists, so the African Savannah Elephant released for the Dense Forest Ecosystem fills High Browsers and Terrestrial Seed Dispersers at once.

Is my reserve progress saved?

Yes, in this browser on this device. Nothing is sent to us, and clearing your browser’s site data removes the ticks. The Clear buttons remove one Ecosystem or every tick.
