Kerala Sasthra Sahithya Parishad (KSSP) effectively aroused public opinion on the requirement to save Silent Valley. They also published a techno-economic and socio-political assessment report on the Silent Valley hydroelectric project. The
poet activist Sugathakumari played an important 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. Dr.
Salim Ali, eminent ornithologist of the
Bombay Natural History Society, visited the valley and appealed for cancellation of the hydroelectric project. A petition of
writ was filed before the High Court of Kerala, against the clear cutting of forests in the hydroelectric project area and the court ordered a stop to the clear cutting. Dr.
M. S. Swaminathan, a renowned agricultural scientist, and then secretary to the Department of Agriculture, called at the Silent Valley region and his suggestion was 389.52 km2 including the Silent Valley (89.52 km2), New
Amarambalam (80 km2),
Attappadi (120 km2) in Kerala and Kunda in Tamil Nadu (100 km2)
reserve forests, should be made into a national rainforest
biosphere reserve, with the aim of "preventing erosion of valuable
genes from the area".
Listen:(8:46) to Dr. M. S. Swaminathan speaking on Sustainable Development, p.83, August 27, 2002 In January 1980 the High Court of Kerala lifted the ban on clear cutting, but then the Prime Minister of India requested the Government of Kerala to stop further works in the project area until all aspects were fully discussed. In December, the Government of Kerala declared the Silent Valley area, excluding the hydroelectric project area, as a
national park. In 1982, a multidisciplinary committee with Prof.
M. G. K. Menon as chairman and
Madhav Gadgil,
Dilip K. Biswas and others as members, was created to decide if the hydroelectric project was feasible without any significant ecological damage. Early in 1983, Prof. Menon's Committee submitted its report. After a careful study of the Menon report, the Prime Minister of India decided to abandon the Project. On 31 October 1984 Indira Gandhi was
assassinated and on 15 November the Silent Valley forests were declared as a national park, though the boundaries of the Silent Valley Park were limited and no buffer zone was created, despite recommendations by expert committees and scientists. ==Park inaugurated==
