Kaziranga National Park Emerges as a Thriving Hub of Aquatic and Herpetofaunal Diversity

• These fish species are more than statistics but rather serve important functions in supporting higher-trophic fauna, such as otters, fishing cats, and waterbirds, through food-web linkages.
• They also support nutrient cycles and habitat connectivity throughout floodplain systems.
• Provide an indication of ecosystem health, with more native diversity often indicating less disturbance.

These indicators assist us in not only tagging Kaziranga as a grasslands/forest park but also as a holistic wetland-floodplain conservation framework.

Herpetofaunal Diversity in Kaziranga National Park

• The concurrent study on herpetofauna yielded a total of 31 species through rapid survey (17 amphibians + 14 reptiles), representing 19 genera and 14 families.
• With the historical specimens incorporated, the total herpetofaunal checklist for Kaziranga is now documented at 108 species, which is greater than half of the 274+ species reported from Northeast India.
• Furthermore, the researchers took advantage of AI-based passive acoustic monitoring to detect amphibian calls in potential breeding habitats, which marks a non-invasive method that allowed for richness to be documented across habitats.
• Ophiophagus hannah (King Cobra), Pangshura sylhetensis (Assam Roofed Turtle), Manouria emys (Asian Brown Tortoise), and Cyrtodactylus kazirangaensis (a species found only in Kaziranga) are a few of the notable species included.

• Amphibians and reptiles act as valuable indicators of environmental change, which means their presence, absence or abundance can indicate habitat health, hydrological balance, and ecosystem connectivity
• The findings of herpetofaunal species in Kaziranga within Kaziranga speak to the undisturbed nature of wetland/stream/forest-edge zones in the park. The necessity of long-term monitoring of herpetofauna as an early warning of stress, which includes climate change, siltation, and hydrology change.
• The diversity of herpetofaunal species also underlines the nominally valued status of Kaziranga as a model protected area for not only megafauna but also for comparatively under-studied groups of species.

Potential Threats and Future Outlook

• The climate change, particularly the alterations in rainfall patterns and higher likelihoods of floods or drought, could modify habitats.
• Floodplains are altered due to silt deposition and river channel shifts and subsequently affect aquatic habitats.
• Overfishing or other damaging practices can lower fish populations as well as disrupt food chains big time.
• Habitat fragmentation and loss of connectivity can disrupt gene flow; therefore, keeping streams and wetlands connected is important for species movement and gene flow.
• Thus, the park authorities suggest ongoing long-term monitoring, enhanced conservation measures as necessary (particularly for threatened species), and a synchronized approach to manage wetlands, floodplains, forest and grasslands together.

Measurements for the Future

• The necessity for aquatic and herpetofaunal studies to be part of the conservation planning process.
• The recent rising numbers stress the need for conservation to extend beyond charismatic megafauna such as tigers and rhinos as biodiversity surrogates and to advocate for protecting unnamed and unglamorous, small-but-vital species.
• Emphasizing the potential for the park to be a model for wetland and floodplain conservation in the Brahmaputra basin and beyond.
• Addressing the power of contemporary monitoring techniques (such as AI-based acoustic monitoring) to improve biodiversity monitoring.
• In summary, Kaziranga remains a living laboratory of biodiversity, reminding us that healthy ecosystems exist on layers of life. From fish and frogs to reptiles and rivers, not just the magnificent mammals we so often tell stories about.

A Need to Put Light on the Silent Contributors

The survey at Kaziranga National Park has revealed 77 species of freshwater fish and 108 species of amphibians & reptiles, and it illustrates a vital message: authentic conservation work often requires exploring below the water's surface. These fish and herpetofaunal communities are working silently to contribute to ecological balance, habitat integrity and biodiversity resilience. Given the enormous pressures of climate change, siltation and hydrologic change, it is high time that the authorities of Kaziranga National Park actively extend into wetlands, streams and floodplains, protecting and conserving these rich but fragile ecosystems. The research and monitoring of these systems represents a significant step forward, but the real work will be to monitor, protect and manage these hidden features of Kaziranga into the future.
