Copper Tailings Rehabilitation
Designed by Yuan Pan with EcoKnow Creator 1.0
The Situation
A copper mine tailings dam in the Philippines has ruptured, spilling heavy metal contamination across the surrounding land and into local waterways. Native plants are dying, fish populations are crashing, and the community is outraged. Your mission is to contain the disaster using Vetiver Grass and other remediation measures, restore native vegetation, and recover fish stocks - all while managing a limited budget.

Over 12 rounds, with 4 actions per round and a budget of 8,000 credits, you must manage the ecosystem to meet your objectives.
What are "Mine Tailings"?
The toxic waste material left over after the valuable metals have been extracted.
In this case, from extracting Copper Ore.
You can perform limited actions to try to meet your Objectives.
You can Introduce or Harvest certain entities, others you can only observe.
Understanding how they interact across zones is key to your strategy and it will take some trial and error.
Introduce These
Vetiver Grass
Vetiver grass is known for its ability to tolerate heavy metals in soil, and can help stabilise soil to prevent erosion. It can work in conjunction with Citric Acid.
Native Plants
Benguet Pine won't tolerate heavy metals in the soil, so having this around is a clear sign that soil is in a good condition.
Citric Acid
A new discovery! Citric acid, the same thing that's in soft drinks like Sprite, can actually help leach out heavy metals from polluted ground.
To Different Areas
To Meet Objectives
Financial Sustainability
Maintain a healthy budget while investing in remediation. Don't overspend on introductions.
Keep budget above 2,000 for 2 rounds
Healthy Waters
Ensure fish populations recover and remain stable by reducing heavy metal runoff into the waterways.
Keep Fish above 400 for 3 rounds
Native Restoration
Restore native plant populations to healthy levels by remediating heavy metal contamination on land and tailings.
Keep Native Plants above 500 for 3 rounds
Watch Out For
Heavy Metal
This is what you need to clean up, the toxic run off from the copper mine tailsite.
Overspending
Spending too much too early can leave you short on funds later, or mean you miss your Objectives.
Why This Matters
This scenario is based on real environmental challenges faced by communities near mining operations in the Philippines and around the world. Tailings dam failures are one of the most significant sources of heavy metal contamination, affecting soil, water, and the livelihoods of local people.
Phytoremediation — using plants like Vetiver Grass to absorb contaminants — is an active area of scientific research. It offers a lower-cost, more sustainable alternative to conventional remediation, but requires careful planning and long-term commitment. The trade-offs you encounter in this game reflect real dilemmas facing environmental managers.
The exciting new development is the use of Citric Acid in high concentrations — this can be used to help speed up soil regeneration. This is abundant, low cost and is found in the same drinking sodas we enjoy on a regular basis, like Sprite.
By playing this scenario, you're engaging with the same mathematical models (Lotka-Volterra population dynamics) that ecologists use to study species interactions and ecosystem recovery.
Your decisions mirror the choices real stakeholders must make when balancing environmental restoration with limited budgets and community expectations.
