There is an imminent threat to the trans-Himalayan areas in India due to increasing human activities. In this context the study is conducted to study ibex in a relatively safe population to learn about its habitat requirements and ranging behaviour. The study area is part of the Pin Valley National Park (PVNP; 31o 6' 40'' to 32o 2' 20'' N latitude and 77o 41' 21" to 78o 6' 19" E longitude), located in the South-East of the Lahul and Spiti district of Himachal PradeshenMammalsUngulatesHimalayan ibexPrey speciesTrans-himalayaRanging behaviourHabitat requirementPin Valley National ParkHimachal PradeshThesis
