Around 600 native trees and shrubs are to be planted at Normand Park and Eel Brook Common.
Councillor Wesley Harcourt says the tennis court-sized areas ensure “cleaner air and safer habitats for our local wildlife”.
The one in Normand Park was funded by a donation from 52-year-old Shamita Ray, a yoga teacher who’s lived in Hammersmith for 30 years.
She says “you can’t really go wrong with trees, it’s so pleasant to be within them”.
