A crash course in carbon ft. Dr Susan Orgill, Select Carbon
Carbon – I bet you’ve been hearing a lot about it recently. But, what is Carbon, why is it so important, and is it just a buzzword, or is there more to the story?
My name is Steph Coombes, and in this episode I sit down with Dr Susan Orgill to learn about carbon, it’s role in the ecosystem, and how land managers can improve their soil carbon content for improved soil health, production outcomes, and carbon farming opportunities.
Dr Orgill is an applied soil scientist with over 15 years’ experience in soil carbon research and development, and to say that she lives and breathes all things carbon is an understatement!

The challenges in protecting native vegetation ft. Danny Hayes, Mainoru Station
Mainoru Station is a 1300 km2 cattle station, 250km north east of Katherine. In the 10 years since Danny and Cathy Hayes purchased it, they have been relying predominantly on native vegetation for the cattle production system.
In this episode Danny shares the challenges he has in managing his native pastures, including below average rainfall, grazing pressure from both cattle, feral animals, and wildlife, and of course weeds.
He also discusses the Territory Conservation Agreement he entered into, how and why he chose the site he did, and what he hopes to achieve.
A Territory Conservation Agreement supports land managers to protect areas of conservation importance on their properties.
They are a 10-year voluntary agreements between Territory Natural Resource Management (TNRM) and a land manager.
The program is supported through funding from the Australian Government's National Landcare Program. The agreement is a contract, but it is not registered upon the title of the property or binding to future owners.
My name is Steph Coombes, and for this episode I travelled to Mainoru Station to learn about how Danny manages his native vegetation, and what impact the Territory Conservation Agreement will have.

Changing up the way we fight fire ft. Doris Baylis, Mataranka Station
When Doris Baylis and her husband took over the lease of Mataranka Station in 2016, they knew they would be busy - busy with infrastructure maintenance and cattle work, that is.
What they didn't bargain for was an annual, ongoing problem with wildfires.
It was, you could say, a true initiation by fire.
After losing almost 12,000ha to fires in 2017 and 2018, which equated to 15% of the properties grazing land, they knew they could no longer rely on traditional fire management.
So, they entered a Practice Change Partnership with Territory Natural Resource Management.
A Practice Change Partnership supports farmers to implement sustainable agriculture practices that will help protect native vegetation and biodiversity, and support the productivity of their operation.
These may be in the form of strategic weed and fire management plans, a change in water points, implementing new ag technology and different grazing methods for example.
The project is supported through funding from the Australian Government’s National Landcare Program.
My name in Steph Coombes, and in this episode I travelled to Mataranka Station to learn about how the Practice Change Partnership between Mataranka Station and Territory NRM works, and what the outcomes have been so far.

Regenerative is the new normal ft. Jeremy Trembath, Lonesome Duck
When the Trembath family acquired “Lonesome Duck”, a 1000ha grazing and cropping property in the Katherine region of the Northern Territory, they managed the land using conventional farming practices.
It wasn’t until around 25 years later that the property began to transition from conventional to regenerative farming practices.
By his own admission, Jeremy states that in his early years managing the property, his choice to continue doing things as they’d always been done resulted in the soil health declining. It was until he was gifted a book on regenerative agriculture that Jeremy decided to do things differently and have soil health as the central focus of the entire agricultural operation. But, making the decision is one thing – knowing where to start, and actually starting, are a whole different story.
My name is Steph Coombes, and in this episode I sit down with Jeremy to learn about the practice changes he has implemented on Lonesome Duck over the past several years, what’s worked, what hasn’t, and where to next.

Conservation on a Cattle Station ft. Garry Riggs, Lakefield Station
When Garry Riggs and his family acquired Lakefield Station in 1999, it was a bare block.
Located on the Sturt Plateau, Northern Territory, Lakefield is home to savannah bushland, floodplains, swamplands and freshwater lakes, with an annual average rainfall of 800mm, delivered often in a tropical wet season.
As development infrastructure to support cattle production on the 58,000 hectare property progressed, so did the development of conservation sites.
In this episode Garry shares his experience of working with Territory Natural Resource Management over the past decade on two projects – a Territory Conservation Agreement, and a Practice Change Partnership.
A Territory Conservation Agreement supports land managers to protect areas of conservation importance on their properties.
They are a 10-year voluntary agreements between Territory Natural Resource Management (TNRM) and a land manager. The program is supported through funding from the Australian Government's National Landcare Program. The agreement is a contract, but it is not registered upon the title of the property or binding to future owners.
