Residents braved the cold to help plant 30 trees in a Seven Kings park on Saturday.
The replacement trees have been provided for South Park, in South Park Drive, by charity Trees for Cities.
As well as getting their hands dirty, visitors enjoyed arts, crafts and refreshments at the community day.
Children from South Park Primary School, in Water Lane, also planted six trees on Thursday.
It is part of a London-wide scheme from mayor Boris Johnson to replace and remove trees and introduce new species in urban areas.
The South Park Users Group helped choose the new plants and Vision Redbridge and Redbridge Council are working in partnership with the charity.
Sharon Johnson, chief executive of Trees for Cities said: “This project is a wonderful example of this and an opportunity to continue to plant trees for future generations to enjoy.”
The charity also organised the planting of 15,000 trees in 10 days to create an urban woodland in Ray Park, Woodford Green, in January.
In February, trees were planted near Christchurch Primary School in Ilford as part of an initiative for streets and saplings from last year’s project in Goodmayes Park are taking root.
