CHANDIGARH3GREENING DELHI 4

Potential of Forest Cover in amelioration of environmentEffective carbon sink Green lungs of the city Acts as dust filter/collector Acts as a shelter belt and dissipates sound/noisePollution scavenger Absorbs gases and gather particulate matter

7Massive planting of seedlings by various Govt. agencies Involving NGOs, residents associations etc. in tree planting & protectionMotivating people to plant at least one tree per family Free distribution of seedlings to publicTo increase mass awareness for trees To bring all greening agencies under one umbrella8Components of Greening Delhi Action PlanIncrease in vegetation byProtection of existing trees/forestNeed specific models prescribed for different categories of lands for plantation alongRoadside, traffic intersection and central vergersDrainsExisting protected forestsGaon Sabha lands, resident colonies, parks, etc.City forestsRidge 9Mass awareness campaigning strategy for Greening DelhiTo sensitize the people on need of increased forest/trees by:Enlisting NGOs active participationSchool children main target groupUse various medias like:Press, AIR/FM, electronic media, cable TVs, advertisements in newspapers, theatre groups, computerized display of messages at traffic intersections etc.10

A harmonious blend of buildings, trees and other landscape elements, with the backdrop of the Shivalik hills, enhances its aesthetic value.

STRATEGYTO INCREASE GREEN COVERMassive Plantation of tall saplings Maintenance e.g. regular watering. Protection by putting tree guards.Emphasis on plantation of indigenous trees.Selection of species based upon- Environmental consideration- Site condition

COMPONENTS OF GREEN COVER Roadside Plantations Gardens and greenbeltsPlantations in institutions Creation of Herbal Gardens in Academic institutionsEnrichment planting in Reserve Forest and Wildlife Sanctuaries

Road side plantationsAvenues of One tree species on one roadSelection of Tree species based upon: HardinessEvergreen foliagePollution abetment requirement PARKS AND GREEN BELTS1900 small and big parks A specified percentage has been earmarked for woodlots depending upon size of park:SIZE OF PARKAREA OF WOODLOTS1.0 Acre30%1.0 - 5.0 Acre 40%5.0 To 20.0 Acre50%More than 20 Acre60%PROTECTION & IMPROVEMENT

Regular replacement of dead, dying and diseased trees.Under planting under over-matured & matured trees. Medium size Species to be planted under overhead electric lines & telephone lines.Removal of weeds like Lantana & Parthenium from the city.Composting / Vermi Composting to prevent burning of leaves.

PROTECTION & IMPROVEMENT

STEPS Control of pest attack on trees.Removal of concreting/ tiling around the tree stem.Removal of Kiosks, advertisement boards from tree trunks to avoid damage to treesRemoval of lights (bulbs & tubes) from trees.Promoting Rain water harvestingPROTECTION & IMPROVEMENT

Creation of herbal gardens in educational institutions.Transplantation of trees.Mulching of leaves for protection of saplings.Restoration & Conservation of Biodiversity.
