Research reveals how proximity to trees affects property value and public attitudes toward urban trees

Consensus Summary

Research from the University of Technology Sydney (led by Associate Professor Song Shi) found that trees between 10 and 20 meters from a property boost home values by $30,000, while those within 10 meters can reduce value by up to $70,000. The study highlights a paradox: while trees enhance neighborhood appeal—such as on streets like Ocean Street in Woollahra—they often face resistance from homeowners who dislike their proximity. Experts like landscape architect Matt Cantwell and environmental services manager Danielle Hughes explain that trees provide cooling benefits (lowering temperatures by nearly 10°C and cutting cooling costs by 20–30%) and environmental advantages like reduced energy use, but many residents prioritize maintenance concerns, seasonal mess, or obstructed views. Studies by Dr Nader Naderpajouh revealed disparities in tree coverage across Sydney, with western suburbs like St Marys gaining canopy while areas like Liverpool lost trees, possibly due to development. Despite these benefits, homeowners often view trees as someone else’s responsibility, leading to conflicts over maintenance and species selection. The consensus underscores a tension between urban greening and individual property preferences, with clear economic trade-offs tied to tree placement.
