The size of a tennis court, micro-forests have been devised to restore biodiversity in urban environments.
Since the first tiny forest was planted in the Netherlands in 2015, the method has been growing in popularity, particularly in Europe.
The method replicates mature ecosystems, but on a small scale, with each plant, grass and shrub chosen carefully to complement the others.
Research shows the important role of forests in storing carbon and helping to fight climate change.
$70,000 has recently been raised by the Canberra local community in Australia to crowdfund a micro-forest project.
