Mangar Bani along with neighbouring villages of Gwal Pahari, Baliawas and Bandhwari, which lies near the forested parts of Southern Delhi Ridge of Aravalli range, is an ecologically sensitive under threat biodiversity area dotted with disused mining pits. The flora, fauna, and ecology has degraded which severely needs restoration by replacing the invasive Vilayati kikar weed with the 3-layer cover of native grass, shrubs and trees. This area lies in the habitat of leopards. 95% of the forest is covered with the slow-growing dhau tree (anogeissus pendula). Mangar Bani has native plant species such as Dhau and wild eagle can be seen here.
