I wish to thank the following persons, without whom the execution of this study would not have been possible: • My parents, for giving me the opportunity to make my dream a reality, amidst difficult times, and my brothers, sisters, bhabies for all their support, unconditional love and guidance during this study. • My mentor and supervisor Prof. Dr. Rashid Ahmad Khan, for inspiring guidance, constructive criticism and enlightened supervision especially his willingness to help amidst a full program. Your support to promote the spirit of constant work and the maintenance of professional integrity besides other invaluable words will always serve as beacon of light in my life. • My co-supervisor, Late Dr. Muhammad Arshad, for always sharing his expert knowledge, dexterous guidance and for all his patience throughout the fieldwork. I sincerely believe that without his patronage and assistance, this research work would not have reached a successful culmination. • My Supervisory Committee, Dr. Shahid Yaqoob, and Prof. Dr. Munir Ahmad, under whose scholastic guidance and consistent encouragement, I have completed my work. • My class fellows and friends (Rafay, Imran, Fahad, Usman, Akbar sab & Nadeen bhae) who supported me at every step to accomplish this job. There are many other individuals who supported me in various ways, although I cannot mention their names here. I simply say thank you so much for your immense support. • Higher Education Commission (HEC), Pakistan for sponsoring this research project under the Indigenous Scholarship Scheme. • All the staff of the Department of Forestry, Range management and wildlife for all their support and encouragement throughout the study.
