"As per the data available in records of the Bureau based on the information received from the State Forest and Police authorities the total number of tigers killed by poachers in the last 10 years is 384 and 961 number of poachers arrested in the tiger cases," the reply stated.
However, the bureau said that no information was available with it regarding the conviction of the accused in these cases.
"The data makes it clear that successive governments have not been able to check killing of tigers by poachers and therefore there is a need for a special initiative to conserve this wild species or make changes in current laws to make them more effective else," Tomar said.
For conservation of the country's national animal, the government had launched 'Project Tiger' in 1973. As per a 2014 assessment, India has the highest number of tigers in the world at 2,226, according to the website of the Ministry of Environment, Wildlife and Climate Change.
