The Ridge, Delhi’s oldest natural heritage and forest, is sculpted on quartzite deposits, which have cracks from 2 billion years of natural history. This recharges 60% of the rain falling on it. All rain fed aquifers surrounding the ridge are an incredible resource for pure water and must be preserved by protecting their recharge zones.
Many parts of the Southern Ridge which is notified as reserve forest are not demarcated on the ground!. This picture will become clear from the maps and the data collected from there given below.
