RECOMMENDATIONS :

Development Of Potential Patches

• Through plantation and natural regeneration

• Control of Invasive species ( e.g : Chopping & Lopping of

Prosopis juliflora)

Corridors• Natural Drainage Channel (e.g : Palam Drain Corridor)• Railway Tracks (afforestation in buffer area around

railway track)

Individual Buildings and Wildlife Garden

• Wildlife Gardening • Verticalscaping• Hedges• Rooftop Gardening
