Restoration works by removing the invasive species suppressing native plants, replanting natives in the cleared ground, and letting soil and water conditions determine how fast they establish. As native cover and structural diversity rise, wildlife recolonizes the site.
BDI = 100 * nativeCoverFraction * avgNativeGrowth
dInvasive/dt = -removalRate * invasiveCover
dNative/dt = +plantRate * emptyCover * (0.4 + 0.6*soilQuality)
weed re-invasion of empty cells ∝ (1 - soilQuality)
- Invasive removal rate — how aggressively crews clear invasive plants back to bare soil each season.
- Native replanting rate — how much bare ground is replanted with native seedlings each season.
- Soil / water quality — site conditions; higher values speed native growth and suppress invasive re-colonization of bare patches.
- Wildlife return — toggles animal visitors that appear once biodiversity crosses a threshold.
Real-world relevance: this loop mirrors actual restoration projects — wetland reclamation, coral outplanting, and prairie reseeding — where removal, replanting and site conditions jointly determine how fast an ecosystem recovers.
