If you provide consulting services or contracting services or are employed by managing authorities dedicated to the care and conservation of trees in our towns and cities to make them more liveable, or simply a pathological tree lover, then the Virtual TREENET National Symposium conference is for you!

CEUs are offered for ISA Accreditation & for Arborists Registered with Arboriculture Australia

Valuing our Trees

Green is the New Gold: Money Does Grow on Trees.

This year's Symposium provides a conversation about the economic value of trees. The benefits of the urban forest are broad ranging, and research continues to investigate their values. There are times that we need to justify the dollar value of the trees that we are advocating for and finding approaches and research to support this is crucial to the process.  That's where this 22nd Virtual TREENET Symposium comes in!

Features will include a direct discussion of the topic, a look at cost models of trees and an analysis of who is doing what in the area of tree valuation.

As always the Symposium will feature some other key topics, including turning grey spaces into green, celebrating red gums, how does your street garden grow, plus much more.

For access to all sessions from the 2021 TREENET Symposium, you simply need an appropriate delegate log in.

Green is the new Gold – the value of urban trees

David will outline the key lessons we have learned about the value of urban trees. Trees are valuable even if they don’t generate profits for somebody.

Root Penetration of PVC Pipes

This presentation is based on research by Susan Bendel that focused on the interaction of roots from Eucalyptus leucoxylon, Lophostemon confertus, Callistemon salignus, Allocasuarina littoralis, Acer palmatum and Pyrus calleryana with stormwater pipes. The pipes had cracks of 0.04mm, 0.66mm and 1.48mm cut along their upper surfaces. There was no significant difference in the mass of…

Canopy Cover measured by tree by year, affordably

Canopy cover benchmarking and change measurement is critical to urban greening strategy, planning, execution and verification. Previously, cost and effort has meant the intervals for assessment have often been 5 years or more with data based heavily reliant on sampling or averaging techniques, largely limiting the work to an historic point-in-time % measurement.  Using fine-scale…

Change management and tree metrics

The World Health Organization estimate that 60% of the world’s population will live in urban areas by 2030; the competition for urban space will only increase and good planning is required.
