The hill-stations of Darjeeling and Nilgiris, situated in India, are iconic examples of human settlement and development in ecologically sensitive regions. The establishment of these hill-stations is a fascinating tale that intertwines historical, ecological, and environmental factors, shaped by the colonial past and later, evolving into popular tourist destinations.

#### Historical Context:
Darjeeling, nestled in the Lesser Himalayas, was initially inhabited by indigenous communities like the Lepchas.

This transformation altered the local ecosystems and led to the displacement of native flora and fauna. The ecological balance of the region was disrupted,
