In the nineteenth century, British demand for timber expanded commercial extraction across parts of the Himalayas. The story of Frederick Wilson in the Bhagirathi Valley of Tehri-Garhwal illustrates this shift: deodar and chir forests that had long supported local economies were increasingly treated as commercial resources for large-scale extraction.
Colonial forest administration also restricted customary access and strengthened state control over forests. The long-term significance is institutional as much as ecological: present debates over conservation, community rights and forest governance operate on landscapes and legal traditions shaped by that earlier transformation.
