How do savanna landscapes change due to gamba grass invasion, and is it possible for these ecosystems to be restored? These questions are being investigated by our project which aims to improve our ability to manage invasive grasses across the north, by reducing high-risk gamba fires and by predicting and preventing ecosystem failures due to invasive grasses like gamba. Recent fieldwork in the Daly River and Darwin regions has involved measuring the fuel loads and patterns of curing (drying out) in gamba-invaded and native grass savanna ecosystems. Researchers are also measuring the amount of native plant seeds in the soil from these areas which can tell us if and how invaded savanna might recover following control measures. With many stakeholders keenly interested in gamba grass management, project leaders Dr Natalie Rossiter-Rachor (CDU) and Professor Samantha Setterfield (UWA) have given a range of presentations on their work at meetings and conferences in both the Northern Territory and Queensland, as well as the USA.
Together, researchers and Traditional Owners have identified indicators that they can use to monitor and evaluate the health of country. […]

Our Northern Hub Newsletter highlights what's going on in our research projects across northern Australia. It includes latest findings, what's coming up and what this all means for sustainable development and land and water management in the region.
The North Australia News Roundup is an informal monthly collation of news relevant to developing northern Australia. It aims to facilitate cross-sector and cross-region knowledge sharing, and more informed conversations and decisions about the future of the region!
