Beyond its biodiversity, Pidurutalagala plays a critical role as a watershed for Sri Lanka’s Central Highlands. The mountain’s steep slopes give rise to numerous waterways that cascade down, providing a year-round water supply to the communities living along the eastern escarpment. These streams and rivers are lifelines for agriculture, irrigating tea plantations and rice paddies, supplying drinking water, and sustaining the ecological health of the surrounding areas. In a country where water management is vital, Pidurutalagala stands as a natural guardian, ensuring the flow of life to the lands below.
