Biological Park


Sanjay Gandhi Biological Park


The Park was established first as a Botanical Garden in the year 1969. The then Governor of Bihar, Sri Nityanand Kanungo, provided almost 34 acres of land from the Governor House Campus for its creation. Later on, in 1972, Public Works Department contributed another 58.20 acres and Revenue Department transferred 60.75 acres land to the Forest Department to help develop this park further.



Since 1973, this park has been developed as Biological Park. The land acquired from Public Works Dept. and the Revenue Dept. were declared as  Protected Forest by the State Govt. on 8th March, 1983. The park is classified as one of the 21 large zoos in the country.

National Zoo Policy


The National Zoo Policy adopted in October 1998 highlights the need for adequate financial and technical resources for effective functioning of the zoos across India. It lays emphasis on co-ordination between the zoos and eminent research/ education institutions on various aspects of zoo and animal management. The zoo policy also aims at giving proper direction and thrust to the management of the zoos.


Success story of Rhinoceros breeding


This is a matter of pride for the park that it houses the maximum number of one horn rhinoceros in captivity only after Saint Diego wild animal park, California, U.S.A.


The first pair of rhinoceros was brought from Assam in 1979. One male rhinoceros was rescued from west Champaran in 1982. The breeding could only start in 1988. Then the park never looked before. The park witnessed the birth of two calves in 2011. At present the zoo houses 11 rhinoceros (5 males and 6 females) of four different bloodlines.
