The gharial is classified as Critically Endangered on the IUCN Red List.
Historically, gharials inhabited river systems across Pakistan, northern India, Nepal, Bangladesh, and Myanmar. Over the 20th century, habitat destruction, hunting, and river modification caused drastic range contraction. Today, viable populations persist primarily in India and Nepal. Entire national river basins that once supported breeding populations no longer host them. This geographic collapse occurred within a timeframe shorter than a human lifespan. The loss reflects cumulative pressures rather than a single catastrophic event. Fragmentation has left relict populations isolated and dependent on conservation management.

Range contraction magnifies extinction risk by reducing ecological redundancy. When a species disappears from multiple countries, genetic diversity declines. Local adaptations vanish along with populations. What was once a widespread predator becomes a conservation emergency. The speed of disappearance highlights how gradual habitat degradation can produce sudden tipping points.
The gharial’s retreat across South Asia mirrors broader freshwater biodiversity decline. Rivers are among the most altered ecosystems on Earth. As water demand rises, free-flowing systems shrink. The disappearance of a top predator signals deeper structural collapse within aquatic food webs. Reversing that trend requires basin-wide cooperation across political boundaries.
