Corridor Current
Open wildlife crossings. Spread the migration. A fast route is only useful if it does not become a bottleneck.
The crossing ledger
Tap a crossing to triple its permeability. Tap again to undo. All route flows recalculate together; restore alternate paths to relieve crowded ones.
Compare the baseline routes, then restore crossings with room to share the flow.
Field notes · model & source
The network treats habitat crossings as conductances. A unit migration flow is injected at the western reserve and removed at the eastern reserve. A grounded graph-Laplacian solve distributes it over every connected path. Difficulty is the resulting effective resistance; lower is better. Crossings must all stay under the displayed flow cap.
Restoration triples a crossing’s conductance. The dry-season scenario reduces one route’s permeability, while fragile crossings use a tighter crowding limit. New landscape changes baseline conductances, targets and the dry-season crossing. These are synthetic game landscapes, not wildlife forecasts.
