As hypercarnivorous apex predators, crocodiles regulate prey populations and remove carcasses from water channels, contributing to the health of mangroves. Thus, their presence signals that creeks and rivers still sustain a functioning food web despite immense pressures from human settlement, cyclones and sea-level rise. Better juvenile survival also indicates that the breeding habitat retains sufficient quality. This is an important ecological marker for the delta, where rising salinity and erosion are narrowing the niches available to wildlife. If the crocodile population can establish a stable age structure, it may bolster the resilience of the Sundarbans’ mangrove networks. The species’ trajectory also highlights what can be done for other neglected ones. Current Schedules under the Act should be accompanied by proactive, well-funded recovery plans, and public communication strategies need to be recalibrated. The crocodiles did not gain numbers because they became beloved but because conservation agencies invested in their protection. A similar shift in focus can support other species. Climate change integration is also essential. Saltwater crocodiles tolerate wide salinity ranges but many amphibians or freshwater reptiles do not. Anticipatory measures including identifying climate refugia and enabling assisted breeding are thus required. The recovery illustrates that non-charismatic species can benefit from law and policy with sustained attention. For India, the lesson is that a richer, more inclusive, vision of conservation is possible and necessary.
