Status of Faunal Diversity of Sariska Tiger Reserve in the Aravallis

The reserve has topography of undulating plateau land and wide valleys with flat vast plains to narrow and deep gorges. The terrain of Sariska Tiger Reserve is hilly maintain the character of Aravalli system with sharp log back ridges. The slopes are steeper on their southern aspects than in other direction. The ridges and plateaus are convulated and curved, and run in many directions. There is a major valley referred to as the main valley which runs in a general east west direction through the reserve. The main valleys width ranges from 0.25 km. to 2 km. comprises with Kushalgarh in the west, it forks into 2 branches towards Tulsiwasla in the north-west and Sariska in the south-west. Another major valley, the Sariska-Kalighati valley, runs in a general north-south direction. It is narrow, about 0.25 km. wide for the distance of about 5 km. before it broaden out at Karnawas. At the Sariska, where it links up with main valley, it is almost 3 km. wide. To the south of core zoneI there is a wide valley (1 km. ) which runs northwards from Mandalwas to Kaniyawas near Kankwari at the Sariska. In Sariska, they are in NNE-SSW direction. Sariska in the Northern part of the Aravallis has mainly residual hills, though there is a structural control as well. The residual hills occur as isolated, linear features in the line with the trend of the mountain and are spread from each other by wide gaps (Dhabriya, 1987).
