Ecosystem Metric

Just wondering what goes into the ecosystem metric. It’s killing my environmental rating and building natural features doesn’t appear to help.
=>
Currently, ecosystem is somewhat of a hidden metric. It is decreased by buildings (15% per each building) that harvest natural resources (lumbering, mining, fishing).

Pocket City 2: Ecosystem Metric Breakdown

(Based on dev notes + community testing)

What Lowers Ecosystem

- Resource-harvesting buildings (biggest penalty):
​
- Lumber Mills (cutting trees)
​
- Mines (quarrying, destroying terrain)
​
- Fishing Docks (overfishing)
​
- Bare, unplanted land
​
- Heavy industrial zones (pollution + habitat loss)
​
- Landfills (even covered ones hurt temporarily)

What Raises Ecosystem

- Trees (mass plant everywhere—roads, gaps, vacant lots)
​
- Parks: Small Park > Community Garden > Large Park
​
- Nature buildings: Wetland Reserve > Botanical Garden > Nature Reserve > National Park
​
- Waterfront greening (rivers/lakes with trees/wetlands)
​
- Eco policies: Tree Planting Initiative, Sustainable Development Act
​
- Green power: Solar/Wind farms (vs coal/oil)

Why “Building Natural Features Isn’t Helping”

- Harvesting buildings are canceling gains: 1 lumber mill can erase 10+ parks.
​
- Not enough density: Scattered trees don’t offset heavy industry/mining.
​
- Landfills/industrial zones are too close to green areas.

Quick Fix Plan

1. Pause/remove excess lumber/mining/fishing (keep 1–2 max).
​
2. Blanket the city in trees (every empty tile).
​
3. Replace small parks with Large Park + Botanical Garden (core).
​
4. Add Wetland Reserve on waterfront.
​
5. Enact all eco policies.
​
6. Relocate heavy industry to far edge, buffer with forests.

Your Ecosystem will rebound fast once you cut resource-harvesting buildings and flood the city with green.
