Tilpath Valley Biodiversity Park, is a 172 acre biodiversity area in the South Delhi Ridge within the Northern Aravalli Leopard Wildlife Corridor, located northwest of the Asola Bhatti Wildlife Sanctuary.

[1][2] The valleys in this region were once scattered with sand-mined quarries and dried-up springs due to a lack of groundwater recharge.

There was no natural forest cover, only invasive weed species like Prosopis juliflora (vilayati kikar), lantana, and parthenium.

During its restoration, invasive foreign species were replaced with the three layers of forest community: native trees, shrubs and grassland.

[2] Wildlife surveys are conducted using pugmarks tracking with the pug impression pad (PIP) and by photographing the wild animals.
