The changing Himalayan tree landscape threatens local ecosystems and biodiversity. Climate change disrupts the balance of flora and fauna, prompting native tree species to migrate to higher altitudes. A shift that endangers endemic species and affects food web relationships. Additionally, soil stability, water cycles, and carbon storage are jeopardized as trees move from traditional habitats. Understanding these changes is vital for conservation efforts to preserve Himalayan biodiversity and mitigate impacts on global ecosystems.
