PERTH LOCAL GOVERNMENT
Urban Forestry Context Warren Stephens
Imagine if trees gave off WIFI signals. We would be planting so many we’d probably save
the planet too. Too bad they only produce
the oxygen we breath.

But what happens to urban environments that are low in
coverage?

Climate and UHIE
• Extreme heat days can be deadly • 347 additional deaths during heatwaves across Australia in
January 2009 • 167 excess deaths in Victoria in January 2014 (Climate Council of Australia, 2016., Department of Health [Victoria], 2014)
• Heatwaves have resulted in more deaths in Australia than any other natural disaster combined (4,555 deaths since 1900)
(Coates, L., Haynes, K., O’Brien, J., McAneney, J., & Oliveira, F. D. (2014).
• Street trees can reduce day time temperatures by between 5°C and 20°C.
(Killicoat, P., Puzio, E., & Stringer, R., 2002)

If you cant measure something you cant manage it
• Aerial Laser Scanning (ALS) develops a 3D terrain model – a ‘Point Cloud’
– Each point has x, y, z coordinates
• accuracy of ≈ ± 60 mm (measurable)
– Able to extract ground terrain, buildings, trees and more

• City of Belmont Canopy Plan 2019-2024 – 37 Actions over 5 years – Complement and contribute to the City’s urban
forestry practices • Baseline data • Goal setting and targets • Implementing actions and programs • Monitoring the impacts we are having • Regularly promote this to our community.
Plan for the future
What else do we do to protect and enhance our Urban Forest?
• Recognise the importance, value and scientific complexities of Arboriculture by employing an Arborist on staff.
• Engage qualified arboricultural consultancies for additional, independent advice and support - such as the Arbor Centre.
• Set up TPZ’s around trees in all City development projects. • Continue to pursue innovation and technology changes that support root
growth and health. • Supported other LGA’s with the development of their Urban Forest
Strategies and Plans such as Shire Of Kalamunda, City of Perth, EMRC etc. • Urban Forestry is standing agenda item on Perth Metro Park Managers
Group. • Founding member of the Green Space Alliance. • Member of the WALGA Urban Forest Working Group. • Consult with State Govt re: Design WA guidelines. • Data, data, data. Perpetual measurement of performance against targets.
