An under construction water canal at Ranthambore tiger Reserve is acting as a major hurdle for the tigers. Construction of the canal is underway in the….corner of the park that will join the Kushalipura nalla to the Mansarovar dam. If this is done, it will become a permanent border that will cut the crucial corridor that links Ranthambore National Park to the 128 sq km large Sawai Mansingh Sanctuary.
