Watershed management and ecological restoration of a tea estate, Nilgiris

A landscape extending across several hill slopes and valleys is set in the mountains of Nilgiris, this ongoing initiative is an integrated effort to restore the ecological and hydrological balance of a high-altitude tea estate. The project responds to challenges such as soil erosion, slope instability, invasive species, droughts and declining groundwater, all of which directly affect both biodiversity and land productivity.

The process began with an in-depth ecological and hydrological assessment, establishing a strong scientific foundation for a Resilient Watershed Management Strategy. Four pilot micro-watersheds were identified to demonstrate low-impact, non-cementitious soil and water conservation techniques, restoration of hill wetlands and stream systems and regeneration of native shola forest and montane grassland habitats. Each pilot site tests adaptive solutions for erosion control, improved water retention and the creation of ecological corridors within the working estate.

By combining Assisted Natural Regeneration (ANR) with field-based watershed measures, the project addresses critical issues such as drought, landslides, Invasive species management and habitat fragmentation. The learn>study>develop>demonstrate framework enables a cycle of continuous observation, innovation, and implementation. Over time, this forms a replicable model for climate-adaptive land management, where ecological processes and productive land use are harmonized to sustain both people and nature.
