This Northern Territory (NT) study aims to build on a previous study of the food qualities of native rices, by undertaking a preliminary assessment of the market for wild rice food products and an estimation the costs involved in a small scale pilot harvest. In order to do this, the project brings together Traditional Owners and enterprise develope...
Article
Kakadu National Park and its wetlands are World Heritage and Ramsar listed and are at risk from invasive grasses. However, it appears that not all habitats and native vegetation are equally at risk. We conduct a spatial risk assessment for para grass (Urochloa mutica) invasion across seasonally inundated habitats of the 258 km2 Magela Creek floodpl...

This study applied remote sensing, ground data and historical maps to monitor and understand the dynamics of para grass spread in relation to key habitat features (water depth, fire history and native vegetation) on the 225 km2 Magela Creek Floodplain within Kakadu National Park. Maps of these features were produced from Medium- and High- Spatial-R...
Article
Full-text available
Rice (Oryza sativa L) is an important staple crop that feeds more than one half of the world's population and is the model system for monocotyledonous plants. However, rice is very sensitive to salinity and is the most salt sensitive cereal crop with a threshold of 3 dSm-1 for most cultivated varieties. Despite many attempts using different strateg...
Article
The seed biology of two ecologically and genetically important sympatric wild rice species from northern Australia was compared – perennial Oryza rufipogon and annual O. meridionalis. The aim was to determine mechanisms of dormancy exhibited at seed shed and to identify factors that trigger or inhibit germination. This information was used to inves...

Gold mining is one of the principal industries in the Northern Territory of Australia. Most of the mining occurs in monsoonal savanna woodland dominated by Eucalyptus and Acacia species with a grass understory. After mining, rehabilitation includes broadcasting a seed mix of Eucalyptus, Acacia and other tree species. Subsequent to initial establish...

Invasion of grass weeds is a major threat for ecosystems. Mission grass (Cenchrus pedicellatus and C. polystachios) vigorously competes with native vegetation and has become a serious problem in northern Australian savanna. A lower density of mission grass has been observed under the canopy of stands of native Acacia holosericea. We used a series o...

Thesis
Full-text available
The abundant and widespread emergent annual grass, Oryza meridionalis, is crucial to the floodplain food chain on wetlands in monsoonal Australia. The floodplains are a dynamic habitat, driven by the annual cycle of wetting and drying. They are also under increasing pressure from anthropogenic change. Although the annual wet season is a reliable oc...
