Range size is a key variable in assessing species extinction risk.
Historical range maps depict the South China tiger occupying broad regions of central and southern China. Modern assessments show drastic contraction, with no confirmed wild distribution. Range reduction is a critical extinction driver because geographic spread buffers against localized threats. As habitat fragments, populations become isolated and vulnerable. Spatial contraction concentrates risk into smaller areas. The tiger’s near-erased footprint represents one of the most dramatic range collapses among large felids.

Geographic range functions as ecological insurance. Widespread populations can withstand regional disturbances such as disease outbreaks or natural disasters. When range collapses, resilience declines sharply. A predator confined to fragmented patches loses dispersal corridors essential for genetic exchange. Isolation accelerates decline.
Rebuilding range requires reconnecting landscapes across political and economic boundaries. Conservation planning must integrate corridors, prey recovery, and human coexistence strategies. The South China tiger’s vanishing footprint illustrates how spatial metrics often predict extinction before headcounts do. Protecting area is as vital as protecting individuals. Maps can reveal extinction trajectories long before final disappearance.
