Portsmouth is the second most densely populated city in the UK and has tree canopy coverage of just 9.8 %, yet there are approximately 86,500 trees in total across Portsmouth of which roughly 8,581 are street trees*. Last year Portsmouth was one of 19 cities in the UK to receive special recognition as a Tree City of the World for their commitment to effective urban forestry management and has begun a programme of community planting projects, with over 5000 new trees planted within the community*.
