The Team

David Lawry OAM

Founder, Avenues of Honour

David Lawry OAM founded the “Avenues of Honour 1915-2015” project in 2004.
He is also responsible for co-founding TREENET (Tree and Roadway Experimental and Educational Network) in 1997 with Dr Jennifer Gardner, former curator of the Waite Arboretum and was its Director until December 2012.  David remains dedicated to Australia’s living war memorials, helping to foster and support special initiatives to raise the profile of the Avenues of Honour project and its aims. This is especially important during the Centenary period of WW1 from ANZAC, the Western Front and coinciding with Armistice Day in November 2018.
With a Degree in Agricultural Science and a long horticultural history in the nursery and landscaping industry, David is a respected champion for the emerging science aimed at improving the establishment and retention of trees in urban settings, particularly street trees.

In 2008 he was awarded the Medal of the Order of Australia:

“For service to arboriculture and the environment, particularly through research and support for sustainable plantings in the urban landscape, and to the community through the Avenues of Honour project.” 

Dr Tim Johnson

Director TREENET

A horticulturist, naturalist and educator by training, Tim’s profession of choice is local government arborist.

His primary foci during twenty five years with South Australian councils have been sustaining the legacy of earlier horticulturists by continuing to establish trees for future communities and adapting local government practices to meet the challenges of increasing spatial pressures, the degradation of urban soils and climate change.

Tim has long been a champion for Australia’s champion and heritage trees and his new leadership role for Avenues of Honour is such a bonus.

Glenn Williams

Volunteer Special Projects

Glenn enjoyed the role of Director of TREENET for 9 years, from January 2013 through to December 2021.

In a past life, Glenn has a background as a former school teacher and adult educator; followed by professional career in local government as a Natural Resources Officer and personal involvement in the care and conservation of natural areas for over 30 years.

As a former Natural Heritage Manager with the National Trust of South Australia, Glenn commanded the Trust’s Register of Significant Trees.  His experience supporting the panel of significant tree experts, only served to increase his love affair with culturally significant trees.  Whilst Glenn is no longer an active volunteer with the Trust’s Significant Tree Team, his passion for special-merit trees remains undiminished.

As a TREENET volunteer, Glenn’s passion for heritage tree conservation continues to be rewarded with a focus on Australia’s living memorials, for war service, sacrifice and suffering, through the national, Avenues of Honour project.
