The type of vegetations in BBP can be broadly classified into two types as described below
Scrub Type (Dry Deciduous Scrub Forests)
Vegetation in this type of forest is characterized by stunted tree growth open canopy of 10% and below. This type of vegetation is the resultant action of repeated hacking by villagers and grazing by cattle in the past from the adjacent villages.
Important upper canopy trees are Anogeisses latifolia, Chloroxylon sweitenia, Acacia leucophloea, Acacia catechu, Stereospermum chelonoides, Zizyphus spp, Diospyros spp, Santalum album, Shorea talura, Azadirachta indica, Terminalia spp, Dendrocalamus strictus etc.,
Whereas Lantana camara, Phoenix acaulis, Cassia tora, Cassia auriculata, Randia floribunda, Pterolobium indicum, Capparis spp, Gloriosa superba form the undergrowth. Acacia instia is the common climber. Grass is generally abundant in this type of forests. Scrub forests afford good foraging habitat for herbivores in rainy season. This type of vegetative is around rocky patches in bear safari and in part of safaris and rescue center.
Southern Tropical Dry Deciduous Forests
In this type of forest, the canopy opening is 10 – 40% and the trees remain leafless during dry months. Top canopy consists of Terminalia spp, Pterocarpus marsupium, Dalbergia latifolia, Dolbergia paniculata, Gmelina arborea, Lagestroemia parviflora, Boswellia serrata, Dendrocalamus strictus. Second canopy consists of Vangueria spinosa, Randia dumentorum, Wrightia tinctoria, Zizyphus jujube, Santalum album, Kydia calycina, Diospyros melanoxylon, Shorea talura and Casia fistula.
The undergrowth consists mostly of grasses with lantana breaks here and there. Eupatorium, Phoenix humilis, Helicteris isora, Desmodium spp. Gloriosa superba form the undergrowth. This type of vegetation is conspicuous in the valley portion all along the streams passing through the BBP.
Southern Tropical Moist Mixed Forests
This type of forests is the mixed deciduous forests with canopy cover up to 35% and above. They are in patches limited to the moist valleys in Ragihalli RF. The species comprising the top canopy of this type are Tectona grandis, Terminalia spp, Pterocarpus marsupium, Dalbergia latifolia, Lagestroemia lanceolata, Pterocarpus marsupium, Bombax malabaricum, Adina cordifolia, Ficus infectoria and other species of Ficus.
The lower canopy consists of Emblica officinalis, Mallotus philippinensis, Kydia calycina, Randia dumetorium etc.
The undergrowth consists of Solanum ferox, Solanum indicum, Helicteris isora, Hemidesmus indicus, Lantana camara, Eupatorium etc. This is the type of vegetation present in the valley –picnic corner, (the old lac reserve).
Other than captive animals available in the Zoo, Safaris and Rescue Centres of Bannerghatta, following animal life forms are found in wild in the Bannerghatta National Park; that visit to the non fenced area of Bannerghatta Biological Park and some of them do live in it.
Elephant, Leopard, Bison, Chital, Sambar, Sloth Bear, Barking Deer, Wild Boar, Wild Dog, Jackal, Mouse Deer, Bonnet Macaque, Striped Hyena, Porcupine etc.
Peafowl, Grey Jungle Fowl, Partridges, Quails, Flycatchers, Wood Peckers, Ibis, Storks, Sunbirds, Flower-Peckers, Thrushes, Eagles, Cuckoos, Parakeets, Orioles, Minivets, Wagtails, Drongos etc., form part of avifauna of the BBP in nature
Land monitor lizard, crocodiles, tortoise, python, rat snake, cobra, krait, viper etc. are the part of animals live in the water holes/ blank area of the BBP.
Frogs, toads, salamander etc., in the water bodies of BBP
Varieties of butterflies, bees, ants, etc are seen in the BBP
