Tilpath valley biodiversity park, spread over 172 acres is a biodiversity area in the South Ridge, immediately northwest of Asola Bhatti Wildlife Sanctuary and south of Sainik Farm. Before the area had valleys dotted with the sand-mined quarries, dried up springs due to no charging of ground water, with no forest cover except the invasive weed species of prosopis juliflora, lantana and parthenium. This was replaced with 3 layer of forest community with native trees and plants such as mahua, haldu, sheesham and bael. Scrubland was restored to attract reptiles and birds. 100,000 trees were planted in 2015 with the effort of 40,000 volunteers in 6 hours and 20,000 trees in 2016 again. Wildlife survey is conducted using pugmarks are tracking using pug impression pad and by photographing the wild animals. It now covers grasslands, hilly terrain, 105 plant species, 103 bird species, 32 butterflies species, 15 herpetofauna (reptiles and amphibians) species and eight mammalian species including leopard, Indian rock python, jackals, neelgai, mongooses, porcupines, small Indian civet, gecko, Sirkeer malkoha cuckoo, nightjar, Indian paradise flycatcher.
