The gharial is one of the world's most endangered crocodilians. Its welfare is tied entirely to the health of large Himalayan rivers and protection from human interference.
Gharial welfare is inseparable from river ecology. These highly specialised reptiles require clean, fast-flowing rivers with sandy banks for nesting and basking — conditions increasingly rare as river systems are dammed, mined for sand, and degraded by pollution. Individual gharials face acute welfare threats from net entanglement (causing drowning), sand mining disturbance of nesting beaches (causing egg mortality), and boat traffic. The recovery of the Chambal River gharial population — through protection of nesting beaches, anti-poaching enforcement, and conservation breeding — demonstrates that welfare improvement at the individual level is achievable when habitat is secured. Each successfully hatched and released gharial represents both a conservation and a welfare success.
