About 2.5 million more trees will be needed in Scotland's towns and cities to create "tree equality", according to the Woodland Trust.
The conservation charity has developed a 'tree equity score' for every neighbourhood in the country to help rebalance the urban canopy cover.
Experts say trees are shown to improve mood, provide cleaner air and create more attractive neighbourhoods and yet many of the most deprived areas have very few.
The mapping has identified more than 40,000 hectares in Scotland with high social deprivation and low tree numbers which will now be targeted for planting.
The areas identified are home to about 1.5 million people.
