Tourist Destination of the Week - Silent Valley national park
Silent Valley national park situated near Palakkad, with its rich bio diversity, is rated as one of the seven wonders of India, and has been a popular eco spot among nature enthusiasts. Covering a core green zone of 236.74 sq. km, the destination forms part of the Nilgiri International Biosphere Reserve, with the UNESCO giving it the ‘Western Ghats World Heritage Site’ title.
The park is one of the last undisturbed tracts of the south western ghats and tropical moist evergreen forest in the country. It is contiguous with the proposed Karimpuzha National Park (225 km²) to the north and Mukurthi National Park (78.46 km²) to the north-east.
Plans for a hydroelectric project that threatened the park’s high diversity of wildlife stimulated an Environmentalist Social Movement in the 1970s called Save Silent Valley which subsequently resulted in cancellation of the project and creation of the park in 1980.
The original name is said to have been ‘Sairandhrivanam’ in local parlance meaning Sairandhri's Forest. As per a prevailing Hindu legend, Panchali or Draupadi, the polyandrous wife of the five Pandava kings, disguised herself as queen Sudeshna's maid Sairandhri, while they were staying in exile. Myth has it that the Pandava brothers, deprived of their kingdom, set out on a thirteen-year exile. It’s believed that they wandered down south, into what is now Kerala, until one day they came upon a magical valley where rolling grasslands met wooded ravines, a deep green river bubbled its course through the impenetrable forest, where at dawn and twilight the tiger and elephant would drink together at the water's edge, where all was harmonious and man unknown. The Pandavas alongwith their wife are said to have camped beside the river, in a cave on a hill slope.
Going by documented records, British botanist Robert Wight had done an investigation of the watersheds in this area way back in 1847. Later on the British named the area Silent Valley because of a perceived absence of the noisy Cicadas usually found in dense forests. Another story attributes the name to the anglicisation of Sairandhri.
Save Silent Valley
‘Save Silent Valley’ was a social movement initiated in 1973, aimed at the protecting the evergreen tropical reserve forest of Silent Valley, to save the prime biosphere from being flooded by a hydroelectric project.
The Kerala State Electricity Board (KSEB) had decided to implement the Silent Valley Hydro-Electric Project (SVHEP) centered on a dam across the Kunthipuzha River in 1973. Following KSEB’s announcement of its plan to begin dam construction, a lot of trees were felled in the area around that time. The area thus became the focal point of ‘Save Silent Valley’, triggering India's fiercest environmental debate of the decade. The main concern was about the endangered species, the lion-tailed macaque, which brought public attention involving environmentalists, writers and activists from other states to raise campaigns against the issue.
In 1977 the Kerala Forest Research Institute carried out an ecological impact study of the Silent Valley area and proposed that the area be declared a Biosphere Reserve. Eventually in 1979 the Kerala Government passed a legislation regarding the Silent Valley Protection Area (under Protection of Ecological balance Act of 1979) and issued a notification declaring the exclusion of the Hydroelectric Project Area from the proposed National Park.
Kerala Sasthra Sahithya Parishath (KSSP) effectively aroused public opinion on the requirement to save the destination, publishing assessment report on the project. Poet activist Sugathakumari played a pivotal role in the silent valley protest and her poem ‘Marathinu Stuthi’ (Ode to a Tree) became a symbol for the protest from the intellectual community and was the opening song/prayer of most of the ‘save the Silent Valley’ campaign meetings. A writ petition was filed before Kerala High Court, against the clear cutting of forests in the Hydroelectric Project area and the Court followed it up by passing an order to stop tree felling. Eminent personalities who visited the place and staged their protest against the hydroelectric project include ornithologist Dr. Salim Ali, agricultural scientist Dr. M.S. Swaminathan, writers and others. Dr. Swaminathan had suggested that the Valley be made into a national rainforest biosphere reserve to prevent gene erosion.
On September 7, 1985 the Silent Valley National Park was formally inaugurated and a memorial at Sairandhri to Smty.Indira Gandhi was unveiled by the then Prime Minister Rajiv Gandhi. On September 1, 1986 Silent Valley National Park was designated as the core area of the Nilgiri Biosphere Reserve. Since then, a long-term conservation effort has been undertaken to preserve the Silent Valley ecosystem.
Union Minister of Forest and Environment Jairam Ramesh and Kerala Forest Minister Binoy Viswam inaugurated the silver jubilee celebration of Silent Valley National Park on Nov.21, 2009.
Silent Valley gets copious amounts of rainfall during the monsoons, but the actual amount varies within the region due its varied topography. In general the rainfall is higher at higher altitude and decreases from the west to east due to therain shadow effect. Eighty per cent of the rainfall occurs during the south-west monsoon between June and September. It also receives significant amount of rainfall during the north-east monsoon between October and November. The mean annual temperature is 20.2 °C. The hottest months are April and May when the mean temperature is 23 °C and the coolest months are January and February when the mean temperature is 18o C.
