West of Augathella, along the winding Nive River, sits Biddenham, a family-owned cattle property run by Guy Newell and his wife Natalie. The river forms a defining feature of the property, supporting riparian landscapes and providing important habitat for native wildlife alongside productive grazing land.
In early 2025, we approached Guy to explore opportunities to work together on landscape and biodiversity projects. At the time, our Western Koala Project was underway, alongside the Coolibah–Black Box and Poplar Box Project, both of which strongly aligned with the natural values present at Biddenham. With extensive areas of Coolibah–Black Box and Poplar Box Grassy Woodland threatened ecological communities (TEC's), particularly along the Nive River corridor, the property was well placed to support these initiatives. These TEC's also provide important habitat for koalas, with existing records and on-ground evidence confirming their presence in the area.
As part of the project activities, we collected an environmental DNA (eDNA) water sample from a local waterhole to investigate the presence and abundance of native fauna, as well as potential pest species. An acoustic recorder was also deployed to help monitor wildlife activity across the site, providing valuable data to inform ongoing conservation and management efforts.
A key focus of our support at Biddenham has been weed management, particularly targeting Mother of Millions and Tiger Pear, invasive species that can significantly impact native fauna and degrade threatened ecological communities. Through a combination of biological control and targeted herbicide treatments, we have worked alongside Guy to reduce these weed pressures and protect the health of the riparian corridor.
Guy has also actively participated in pest management programs, taking part in the initial aerial pest control operation in May 2025, followed by a second program in November 2025. These efforts targeted feral pigs and feral cats, helping to reduce threats to native species and safeguard the ecological integrity of the TEC's along the river.
Building strong relationships with landholders is central to Southern Queensland Landscapes’ work, and it has been a pleasure to collaborate with Guy and Natalie at Biddenham. Their willingness to engage in conservation projects while continuing productive land management demonstrates the value of partnership in achieving positive outcomes for landscapes, wildlife and rural communities.
