Margalla Hills National Park is facing many threats, including stone crushing, forest fires and tree cutting, which ultimately will result in squeezing the actual core habitat and concentration of animal and birds species in certain pockets. Ever-increasing human settlements, mine crushing, fuel wood extraction, wildlife hunting, livestock grazing, road construction, air noise and water pollution and recently installed lights on the Damn-e-Koh road are the main problems in the park area. Director, Zoology Department, Pakistan Museum of Natural History (PMNH), Dr Muhammad Rafique, said such hurdles to habitat and resource partitioning will lead to competition among the species resulting in drastic changes in species composition and their associations.
