Land use change impacts on weed incursion

Understanding and determining mechanisms to prevent weed invasion in coastal vegetation

By improving understanding of which types of land disturbance influence weed invasion and how weeds replace native species, this project will assist in designing management practices to restore native vegetation in coastal areas without the need for long-term maintenance.

Effect of land use and peri-urban development on aquatic weeds

We are interested in understanding the individual growth responses and competitive dynamics of native and invasive aquatic macrophytes in various environmental conditions.  Before initiating a more complex study, we propose to evaluate the effects of a single factor, shading, on the growth of non-native aquatic macrophytes.  This factor is relevant to the larger scope of our research, in which we are investigating the effects of peri-urban development on aquatic plant populations.  (more)...

Land use effects on soil nutrient enrichment: Risks for weed invasion

This project examined various soil and vegetation properties of remnant eucalypt grassy woodlands under different livestock grazing regimes within agricultural landscapes on the southern tablelands and south west slopes of N.S.W. All woodlands contained a minimum of two exotic plant species and there was up to 94% exotic plant cover in the understorey. The most common invasive exotic plants were annual exotic grasses, most of which were introduced in the past to (more)...
