- Description: A 7,680-km basin survey found 3,037 gharials across 13 rivers, with roughly seven in ten in the Chambal; most of the modeled river network remains low-suitability or sparsely occupied.

Geography

Ganga River Basin, India and Nepal

System

Large rivers and sandbar-dependent crocodilian habitat

## WHAT THE EVIDENCE SAYS

A basin-wide assessment surveyed about 7,680 km across 22 rivers and reported a minimum of 3,037 gharials in 13 rivers. The Chambal held 2,097 animals and the next-largest populations were far smaller. Habitat modeling classified only about 10% of the assessed network as highly suitable, while most river length was very low suitability; long-term Chambal counts also indicate recovery has slowed from the rapid gains of earlier decades.

## WHY IT MATTERS / OUR READ

Species recovery can coexist with geographic fragility. The practical question is no longer simply whether numbers are increasing, but whether multiple rivers can support self-sustaining populations so one stronghold is not carrying most of the species' demographic risk.

## CAVEATS / UNCERTAINTY

The basin counts are minimum population sizes from daylight surveys without a formal detection model, and the habitat model lacked independent validation. More than 9,000 releases have occurred, but correlation between release effort and current abundance does not establish attribution.
