Fragmented habitat patches isolate wildlife populations; corridors of natural cover let animals move between patches to find food, mates and genetic diversity.
P(success) = 1 - risk · (1 - width/width_max)
Connectivity ∝ corridors × width
- Corridor width — how wide the vegetated connection between patches is; wider corridors are safer to cross.
- Number of corridors — how many separate connections link the fragmented patches.
- Animal population — total number of animal agents moving across the landscape.
- Predator/road risk — chance an animal fails to complete a crossing (predation, roadkill, exposure).
Green dots are animals safely moving through a corridor; red flashes mark a failed crossing. More/wider corridors raise the success rate and keep patch populations balanced.
