The Leopards of Haryana, the largest predatory mammal of the state, are found in two distinct biospheres, in the Shivalik hill range in the north especially in and around Kalesar National Park and the Morni hills forest, and also in South Haryana in the forests of Northern Aravalli leopard and wildlife corridor. Haryana has nearly 100 leopards in Shivalik and Aravalli, including 24 in Kalesar National park alone, and 40 to 45 leopards in Gurugram-Faridabad Aravali of which 35 in Gurugram alone. Large parts of Aravalli are legally and physically unprotected, with no wildlife crossings and little or no wildlife conservation work resulting in deaths of over 11 leopards in 4 years between January 2015 to January 2019. In January 2019, Wildlife Institute of India (WII) announced that they will undertake the survey of leopard and wildlife, using pugmarks and trap cameras, subsequently leopards and jackals will be tracked via the radio tracking collars. In 2019, the government of Haryana decided to fit all the leopards with radio tracking collars so that their hunting patterns can be studied and the human animal conflicts can be avoided by rescuing leopards straying in human habitations.
