Basic Information

About This Park

Silent Valley National Park in the Palakkad district of Kerala is one of the last undisturbed tracts of tropical evergreen forest in India — a primeval rainforest that has remained virtually untouched for millennia. The park derives its name from the absence of cicadas (whose loud chorus is a constant in most Indian forests), giving the forest an eerie, profound silence. In the 1970s-80s, the Kerala government planned to build a hydroelectric dam that would have submerged a large part of this forest. A powerful people's movement — the Save Silent Valley Campaign — one of India's earliest environmental campaigns, successfully stopped the dam. The park is home to the endangered lion-tailed macaque and an astounding diversity of endemic species.

Learn About the Park

History

Silent Valley is one of the last remnants of virgin tropical evergreen forest in India. In the 1970s, the Kerala State Electricity Board proposed the Silent Valley Hydroelectric Project, which would have submerged significant forest area. The Save Silent Valley Campaign (1973-1985), led by environmentalists, scientists, and local communities, became one of India's earliest successful environmental movements. Prime Minister Indira Gandhi declared it a national park in 1984. The campaign is considered a watershed moment in Indian environmental history.
