Urban trees play a crucial role in providing benefits like cleaner air and biodiversity in cities. A study compared trees owned by the public and private individuals in Great Britain. Private trees are shorter and have smaller crowns, but they are more diverse and healthier. This diversity and healthiness make private trees better equipped to handle climate change and new pests. Managing urban trees to be shorter and smaller may reduce some benefits they provide. It's important for policies to consider and support private tree owners for a resilient urban forest.
