Erratic rainfall and changing weather patterns in Assam are affecting vegetation growth and water availability in Kaziranga National Park and Tiger Reserve and Pobitora Wildlife Sanctuary. Wildlife conservationists have warned that reduced availability of nutritious vegetation could gradually affect the health and behaviour of herbivores such as rhinoceroses, elephants and deer.

Key Concerns

• Poor vegetation growth: Below-normal rainfall in parts of Kaziranga has affected the growth of grasses and plants that provide food for herbivores.
• Nutritional stress: Reduced availability of nutritious vegetation may affect the health and physical condition of wild animals.
• Behavioural changes: Food and water scarcity can alter animal movement, feeding patterns and habitat use.
• Drying of wetlands: Several lakes and beels have experienced reduced water levels, while invasive plants such as water hyacinth have spread in some water bodies.
• Disruption of water channels: Human activities in the adjoining Karbi Anglong hills have reportedly blocked or dried up streams that supply water to Kaziranga.

Ecological Significance

Seasonal flooding is a natural ecological process in Kaziranga. It replenishes water bodies, deposits nutrient-rich silt and supports the growth of grasslands that sustain herbivores.

However, erratic rainfall, intense flash floods and prolonged dry periods can disturb this ecological balance.

Way Forward

• Nature-based solutions, scientific soil studies and regular monitoring of vegetation and water bodies should guide conservation planning.
• Natural streams and drainage channels connecting Karbi Anglong with Kaziranga must be protected and restored.
• Invasive aquatic plants should be managed through scientifically planned wetland restoration.

Exam Hook: Key Takeaway

Kaziranga’s ecological health depends on balanced seasonal flooding, healthy grasslands, functional water channels and adequate rainfall.

One-line wrap: Protecting Kaziranga requires climate-sensitive habitat management that safeguards its grasslands, wetlands and natural water systems.
