Preserving ‘story-telling’ scar trees and Aboriginal heritage

With NAIDOC Week celebrated across the country, we are pleased to report on efforts to preserve culturally modified scar trees and Aboriginal cultural heritage at CSIRO Ginninderra.

Protecting  lands, waters, sacred sites and Aboriginal cultural heritage was the focus for the ‘Heal Country’ theme for NAIDOC Week celebrated across the nation and indeed at Ginninderra from 4-11 July.

In tune with this theme, we were recently able to host the ACT Aboriginal Natural Resource Management Facilitator and an expert arborist on the Ginninderra site, to inspect and inform the preservation of culturally modified ‘scar’ trees.

Over recent years we have been working with local Aboriginal Elders and Representative Aboriginal Organisations (RAOs) to identify scar trees and other sites or artefacts of Indigenous cultural heritage and significance and to incorporate these into site heritage planning and conservation.

Scar trees, also called culturally modified trees, are rare and special features within the Australian landscape. They bear distinctive marks that provide a window into the past culture and lifestyle of our First Nations People.

Significant scar trees have been identified among the old twisted gums, and in several other locations at Ginninderra, as explained at our last community shrub planting by local Buru Ngunnawal Elder, custodian and knowledge holder, Wally Bell.

“These trees and this place are significant because they highlight our occupation of the region,” Wally said. “It is telling the story about how we used the natural landscape and its features to survive for thousands of years. This is one part of a much larger story.”

The permanent scars on these trees provide clues and signs about where, how and when Aboriginal people lived and traversed these areas as well as what they used timber for.

“Scar trees are used for many different purposes”, says Wally. “Most of the tree scars here are small in size, indicating the bark has been removed for coolamons to transport various bush tucker. These would have been used to carry acacia seed, yam daisy, chocolate lily and bulbine lily – all of those small tubers and seeds that were important food sources for Aboriginal people.”

Scars of different shapes and sizes can give clues of timber being used for containers, canoes, shields and shelters, for example.

Many of the eucalypts that carry these scars are over 200 years old and in some cases the trees are fully or partly dead, in danger of falling or nearing their end of life.

By inspecting the condition and structure of each of the trees, the ACT Aboriginal Natural Resource Management Facilitator, and an expert arborist are developing advice for the conservation and protection of the trees and their scars.

Some of the trees are in great condition or can be carefully pruned to improve their structural stability and lower the chance of falling and damaging or destroying the scars.  Other dead or partially dead trees are in much higher risk of falling so the experts advice will be able to  recommend ways to preserve the condition of these trees and scars also.

Further consultation with the local Elders and RAOs will be an important part in determining exactly how these trees, their scars and the stories that they tell, can be preserved for generations to come.

Project update – July 2021

This month marks the end of a 60-year era at CSIRO Ginninderra Experiment Station, as the property has been decommissioned for agricultural research activities.   With CSIRO’s Boorowa Agricultural Research Station fully up and running, and the Ginninderra property being prepared for future sustainable urban living and conservation, it’s timely to reflect on a little of our history.

Ginninderra was acquired by CSIRO in 1958 following the resumption of the former Dickson Experiment Station to make way for the suburb of Dickson. Prior to Dickson, up until 1940, CSIRO operated a research farm at Duntroon, in an area now occupied by Canberra Airport.

Boorowa, in the heart of NSW’s farming district, represents the third move and fourth location for CSIRO’s flagship agricultural research station in the Capital Region.

With all research activities transferred to Ginninderra by 1962, the property hosted six decades of world-leading science. During that time Ginninderra contributed immeasurably to Australia’s farming sector through innovations like the development of BarleyMax and ultra-low gluten Kebari® barley and dual purpose wheats.

At Ginninderra, our scientists field-tested high yielding and disease resistant wheat varieties such as Lawson, Paterson, Gordon, Tennant, Brennan and Dennis.  Ginninderra was home to groundbreaking research into crop and pasture improvement, sustainable farming, plant breeding and the effects of climate change on crop production.

Ginninderra leaves an impressive and invaluable legacy for Australian agriculture. You can read about how CSIRO research into dual-purpose canola, tested and proven at Ginninderra, contributed to a world record breaking canola crop for a NSW farm in 2020.

While agricultural research has moved to Boorowa, a range of other CSIRO or collaborative research continues at Ginninderra. We recently provided an update on the latest autumn burns, a part of the grassland restoration trials being carried out with the Ginninderra Catchment Group.

During National Reconciliation Week (27 May to 3 June) we were pleased to welcome the ACT Aboriginal Natural Resource Management Facilitator and an expert arborist onto the Ginninderra site to inspect and inform the preservation of culturally modified ‘scar trees’. We will provide further news about this invaluable work and further consultation with the Representative Aboriginal Organisations (RAOs) as it comes to hand.

Last but not least, across the gamut of CSIRO research, we continue to advance new work and innovations with a key part to play in sustainable cities and urban living. On this front, we recently launched a new Hydrogen Industry Mission to advance Australia’s transition to clean energy through development of Hydrogen as an emissions-free fuel for electricity, power and  heat generation.
