Why in region

• The Tsarap Chu catchment area, located in the Lahaul-Spiti district of Himachal Pradesh, is set to be designated as a conservation reserve.

Key Points:

• This initiative aims to protect the unique biodiversity and fragile ecosystems of this high-altitude region, which is characterized by its stunning landscapes and diverse wildlife.

Ecological significance

Geographical overview

• The Tsarap Chu, also known as the Tsarap River, originates from the glaciers near Pankpo La Pass and flows through the Zanskar Valley before merging with the Stod River. The river spans approximately 182 kilometers (113 miles) and plays a crucial role in the hydrology of the region.
• It supports irrigation for agriculture in nearby villages, contributing to local food production despite the harsh climatic conditions that limit agricultural viability.

Biodiversity Hotspot

• The catchment area is home to a variety of flora and fauna, including several endemic and threatened species. The region's unique climatic conditions foster diverse ecosystems ranging from alpine meadows to glacial landscapes. Notably, it provides critical habitats for species such as the Himalayan Blue Sheep and Snow Leopard, both of which are adapted to high-altitude environments.
• The designation as a conservation reserve will help safeguard these habitats against threats such as climate change and human encroachment.

Hydrological importance

• The Tsarap River is vital for maintaining the ecological balance in the region. It acts as a lifeline for many communities and supports various forms of wildlife. The river's flow patterns are influenced by seasonal snowmelt and rainfall, making it essential for sustaining both human populations and natural ecosystems.
• By establishing a conservation reserve, efforts can be made to monitor water quality and manage water resources effectively.
