Around 2,000 trees will be felled and replaced with 10,000 new conifers next winter in Bourne Wood near Farnham, Surrey, which doubled as Sherwood Forest for the film.
"Replanting is vital for sustainable forestry and in helping to combat climate change," said a representative for the Forestry Commission, which owns the woodland.
"The older trees are felled for timber when they are mature so that new trees can be planted to provide an attractive wood for the next generation."
In the latest movie version of Robin Hood, Russell Crowe makes his big entrance emerging from a path behind the Scots pines at Bourne Wood.
The woodland was last visited by the film maker Ridley Scott and Russell Crowe more than 10 years ago when filming Gladiator.
Pam Eastwood, film liaison officer for the Forestry Commission, said movie sets took 4 months to build, with trees used to create palisade walls and fortifications.
"Robin Hood has once again made Bourne Wood one of those memorable movie scenes that will be watched worldwide for years to come," she said.
Tree thinning and felling is part of a 10-year plan to protect the wood for the future, she said. It includes tree planting and removal of invasive and non-native shrubs.
