Haridwar, March 3 -- Forest authorities have sounded an alert across the Rajaji Tiger Reserve in view of a potential threat from anti-social elements, wildlife hunters, poachers and wood smugglers, officials said on Monday. This comes after six people from Delhi were penalised Rs.1 lakh for allegedly indulging in hooliganism inside a prohibited area of the Motichur range, they added. Senior forest officials said all ranges of the tiger reserve have been placed on high alert to prevent illegal activities and ensure the protection of wildlife and forest resources during the festive period. "All the ranges of Rajaji Tiger Reserve have been put on alert mode. Intensive patrolling is being carried out round the clock. Suspected persons are being questioned and frisked. Strict action will be taken against violators," said Koko Rose. Officials added that forest personnel have been instructed to maintain heightened vigilance in vulnerable areas to prevent poaching and illegal felling of trees. On Sunday evening, six people from Delhi were penalised Rs.1 lakh after they were caught violating park regulations during routine patrols, said officials. Forest ranger Mahesh Semwal said they were fined Rs.1 lakh and were let off with a stern warning. Authorities said strict monitoring will continue throughout the Holi festival period to prevent any disturbance to wildlife and maintain law and order in the protected forest area. Established in 1984 as Rajaji National Park, the reserve was renamed Rajaji Tiger Reserve in 2015. It spans an area of 820.42 sq km across the districts of Pauri Garhwal, Haridwar, and Dehradun, and is a rich habitat for diverse wildlife. Apart from tigers, the park is home to over 300 Asian elephants, as well as 23 species of mammals, among others....
