Benefits of trees

Life in the City is better because of the parks, gardens and trees our forebears planted, tended and retained. When we understand that trees provide a more liveable environment, we make more effort to preserve existing juvenile and mature trees and we plant more trees for the future. Trees create greener, happier cities. A green city, with lots of trees, foliage, open spaces and conservation areas provides huge benefits to its residents.

'The best time to plant a tree was 20 years ago. The second best time is now.'
- Chinese Proverb

Often we do not recognise the benefits trees in our urban areas provide. When we value our trees, we make more efforts to retain them in the landscape.

In the past trees were often considered only in terms of the costs to maintain them. Now, it is more appropriate to consider the many benefits of trees:


  • attract rainfall
  • cool cities by between 2 to 8 degrees Celsius
  • make extreme weather days more bearable
  • create a more pleasant microclimate
  • reduce glare
  • absorb greenhouse gases like carbon dioxide
  • store carbon dioxide as carbon
  • provide resilience.

Health and wellbeing

  • connect people with nature
  • reduce cortisol levels, decreasing stress
  • encourage outdoor activities
  • make you feel younger and healthier
  • are restorative and reduce mental fatigue, anxiety and depression.


  • increase property value by 20 to 30 per cent
  • create energy savings:
    • cut air conditioning use by 30 per cent
    • reduce energy use for heating by between 20 to 50 per cent.
  • drive economic growth
  • improve air quality
  • intercept stormwater, reducing infrastructure costs
  • filter airborne pollutants, including particulates.

Community building

  • encourage people to get outdoors
  • create opportunities for socialising
  • create a place to meet
  • reflect our historical, social and cultural histories
  • provide a sense of place
  • provide landmarks in the landscape Reduce noise pollution
  • provide fresh, healthy food
  • create community.


  • provide landscape character
  • complement wildlife corridors
  • provide food and shelter for our diverse native wildlife, including insects
    • hollows in older trees provide homes for native birds, mammals and reptiles.
  • intercept rainwater
  • improve water quality and reduce erosion.

Eucalyptus trees take between 120 to 180 years to form the hollows that provide homes for so many of our native animals.

With a growing urban population, we need a more sustainable and a greener city to ensure we maintain a liveable environment.
