A quarter of a Welsh city will be covered by tree canopies within 10 years due to a new plan to boost its “urban forest”. Almost 30,000 trees will be planted in Newport to supplement about 250,000 existing trees. Wales was the first country in the world to measure its urban tree coverage. The council hopes these trees and others planted by private developers and landowners will take canopy cover in Newport – which at 18% had the highest proportion of any Welsh city in 2016 – to 25%. Joanne Gossage, service manager for environment and leisure at Newport council said the city had “green oasis” parks. She said: “We feel that Newport is a very green city and we don’t think it’s too far of a stretch to get to that 25%. “People’s perception of an urban forest is something dark, perhaps menacing and dingy. It’s not. It’s about trees making attractive frameworks in limited open space.”
