Surrounding the Bannerghatta National Park are the forest buffer zones - areas demarcated to reduce and control the interaction between people and the wildlife. The buffer zones are further seen by conservationists as protection against “development” too close to the forest. In recent years there has been tremendous political pressure to open up these buffer zones for development activities, which range from the construction of residential layouts to granite mining. Last year the Government of India responded to the demands of the state government of Karnataka and significantly reduced the buffer zone area around the forest. Commercial mining, stone quarrying and stone crushing operations are banned in the buffer zone, though the park has been threatened for years now by a number of illegal granite quarries operating around it. The reduction of the buffer zone last year by about a 100 square kilometers puts the park at further risk with legal development activities becoming viable much closer to the park.
The forested valleys and granite hills of the Bannerghatta National park has been home to a number of tribes like most forested regions in South India. A number of old temples dot the Suvarnamukhi hills in the park area, a testament to the cultural significance of these forest lands in the history of South India. The modern Indian state has made efforts to move tribal populations out of reserved forest and national parks sometimes by building consensus and at other times, coercively. There are now small and diminishing tribal hamlets in the buffer zone around the Bannerghatta National park. These tribal communities, among them Hakki Pikki tribes and the Irula tribes, live precariously with development activities ramping up around the forest. Migration of the younger generations away from the forests also threaten their language, identity and custom.
