Explanation:

Banni is the largest grassland of Asia situated near the Great Rann of Kutch in Gujarat.

• It is spread over 2,618 kilometres and accounts for almost 45% of the pastures in Gujarat.
• Two ecosystems, wetlands and grasslands, are mixed side by side in Banni.
• The grassland is dominated by low-growing plants, forbs and graminoids, many of which are halophiles (salt tolerant), as well as scattered tree cover and scrub.

In 1955, the court notified that the grassland will be a reserve forest (the most restricted forests classified according to Indian Forest Act, 1927).

• In 2019, the tribunal ordered to demarcate the boundaries of the Banni grassland and restricted non-forest activities.

The Wildlife Institute of India (WII) has identified this grassland reserve as one of the last remaining habitats of the cheetah in India and a possible reintroduction site for the species.

• The Maldharis are a tribal herdsmen community inhabiting Banni.
• The literal meaning of Maldhari is keeper (dhari) of the animal stock (mal).
• The Shola Grasslands cover the states of Karnataka, Kerala and Tamil Nadu.
• The Saramati Grasslands are located in Nagaland.
• The Ukhrul Grasslands are located in Uttarakhand.

Hence option 3rd is correct.
