Gurugram, June 14 -- The Forest Department is planning fresh plantation of about 150,000 saplings and maintenance of existing green cover across Gurugram, officials said on Saturday. As part of the exercise, a Rs.40.64 lakh tender was floated on Friday under the all-state maintenance scheme for upkeep of green cover along the Behrampur-to-Sohna corridor. According to officials privy to the matter, bids have been invited until June 18 for maintenance works, including site-wise irrigation, weeding and protection measures along the 23-km stretch. Tender documents uploaded on the Haryana government website require contractors to ensure a 90% survival rate of plants for two years from the date of work allotment. The programme will involve transportation, planting and maintenance of around 14,000-17,000 saplings across multiple sites in the Gurugram Range. Surender Dangi, divisional forest officer (DFO), said the department is also considering a longer maintenance model to improve outcomes. "Contractors will be penalised through recovery losses if the survival rate is found below 90%. Periodic maintenance checks will be scheduled by the department," said Dangi. Officials did not disclose the exact plantation sites along the corridor....
