New Delhi:The state of trees in the city is “abysmal”, say environmentalists. Recently, NGO Kalpvriksha surveyed Delhi’s trees, covering areas from Ramlila Maidan to Dhaula Kuan, including Paharganj, Anand Parbat, North Campus, Rajghat, Vikas Marg and Moti Bagh and found that most trees are either diseased or dead, top heavy due to incorrect lopping or suffocating due to concretization around roots.
