Bannerghatta Biological Park was initially a small zoo and picnic corner within Bannerghatta National Park (BNP) which was started in 1974. The bifurcation of the Biological Park and the National Park took place in 2002. The Bannerghatta Biological Park covers a total area of 731.88 hectares and includes a zoo, safari park, butterfly park and rescue centre. The Zoo Authority of Karnataka, the University of Agricultural Sciences, Bangalore, and the Ashoka Trust for Research in Ecology and Environment (ATREE), Bangalore, are collaborating agencies. For the convenience of the general public, the Governing Council of Zoo Authority of Karnataka had decided to rename Bannerghatta Biological Park as 'Bengaluru Bannerghatta Biological Park' (BBBP).
