Research reveals mixed property value impacts of trees based on proximity and public resistance to urban trees

Consensus Summary

New research from the University of Technology Sydney reveals that trees within 10 meters of a property reduce its value by up to $70,000, while those 10–20 meters away boost value by $30,000. The study, led by Associate Professor Song Shi, accounts for factors like bedrooms and CBD proximity, underscoring a paradox: homeowners universally value trees but only when they’re not directly adjacent. Landscape architect Matt Cantwell explains this tension, noting that street trees enhance neighborhood appeal—like Ocean Street in Woollahra—but many owners resist them on private property due to perceived mess, seasonal change, or structural risks from roots. Environmental services manager Danielle Hughes highlights the irony, as trees provide cooling benefits of nearly 10°C and cut energy costs by 20–30%, yet residents often prioritize convenience over sustainability. Western Sydney suburbs like St Marys have increased tree coverage, while areas such as Liverpool face declines, possibly tied to development pressures. The findings align with broader trends: while trees are cherished for their aesthetic and ecological value, their proximity to homes sparks conflict over maintenance, privacy, and practical inconveniences like dropped leaves or obstructed views.
