On the northern boundary of Banni, along the Rann, is a land-locked patch of mangrove forest, which presents a unique phenomenon of ecological adaptability. This mangrove patch is nearly 50 km from the present coast line, probably formed several hundred years ago before the sea coast receded due to geological transformations. It still survives without any direct contact with sea water.
Locally known as ‘ShravanKhavadia’ (after the famous mythological character Shravan), the local community regards this area as sacred. In fact this mangrove patch is thriving thanks to the combination of the micro-environmental conditions provided by the saline Rann and the protection that it is given due to its mythological significance.
There are more such land-locked mangrove patches in the same stretch westwards, closer to Lakhpat.
