Deodar trees in Himachal Pradesh’s picturesquare Sangla Valley have revealed the process of climatic shifts from wetter spring conditions that prevailed during pre-historic times to drier conditions from the year 1757 onwards.

A new study has highlighted the critical role of climate variability that is driven by regional and global factors in triggering the geo-hazards, underscoring the need for forest management, sustainable land use, monitoring and early warning systems.

By studying the pattern and characteristics of rings in the trunk of Deodar trees, scientists reconstructed the climatic patterns over the past 463 years and a 168-year rockfall activity in the western Himalayan region. Deodar is native to the Himalayas and is a large evergreen coniferous with needle-like leaves, reach
