The Benefits of Trees
Street trees can transform the character of streets and provide numerous environmental, aesthetic. Cultural and economic benefits. In the long term, they often create a very real ‘sense of place’ and dramatically enhance the public domain.
- A single mature tree can absorb up to 21 kg of carbon dioxide each year and release enough oxygen back into the atmosphere to support two people’s needs.
- Trees reduce energy consumption by shading pavement, cars and buildings. Shading of the asphalt pavements can also extend its life.
- Trees remove gaseous pollutants by absorbing them through the leaf surface as well as capturing and removing particles from the air.
- Tree canopies, trunks and root structures filter pollution out of stormwater and reduce the amount of pollution that is washed into drains and catchment areas.
- Trees intercept and reduce raindrop and runoff, which reduces erosion.
- Trees provide habitat and food sources for urban animals.
- Trees improve the economic performance of the city by increasing the attractiveness of business and tourism areas. People typically linger, shop and dine longer in tree lined streets.
- Trees reduce energy consumption, through shading and reducing the ‘urban heat island’ effect.
- Shops, apartments and housing in well-planted areas usually attract higher rents and sale prices.
Social &Psychological Benefits
- Trees provide a buffer between pedestrians and cars.
- Studies show a strong correlation between well-planted areas and reduced social services, domestic violence and strengthened community ties.
- Trees create a feeling of relaxation and well-being. Hospital patients are shown to recover quicker and with fewer complications when in rooms with views of trees. Workers and students are shown to be more productive when their environments have views of trees.
- Street tree canopies can shade pedestrians, diminish traffic nose, screen unwanted views and reduce glare.
- Street trees can define precincts and provide a link to our history. Tree lined streets can provide orientation, define road hierarchy and contribute to the overall urban character of a suburb.
- Street trees contrast with apartments and larger buildings.
Trees provide seasonal interest and natural beauty through foliage, including leaf patterns, flowers, bark, fruit and canopy.
