Revisit of Shivalik region in different states of northwestern India

摘要

Shivalik region is sandwiched between Himalayan ecosystem and Indo-Gangetic plains in northwestern India. However, its area is reported to range from 2.14 to 8.00 m ha in northwestern India by different workers. Based on geology and physiography, we demarcated the Shivalik region (3.33 mha), covering hills (1.79 mha) and its piedmont plains or foot hills (1.54 m ha) in the states of Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Punjab, Haryana, Uttar Pradesh and union territory of Chandigarh at an elevation ranging from 217 to 2332 m above MSL. The delineated map showing Shivalik region will be useful in conserving the natural resources of the region without any dispute over its location and area.
