Biodiversity impacts of Chilean needle grass Nassella neesiana on Australia’s indigenous grasslands
The exotic invasive Chilean needle grass Nassella. neesiana (Trin. & Rupr.) Barkworth has been recognised as a major threat to biodiversity in the endangered natural grasslands of south-eastern Australia. Research was undertaken in Canberra and Melbourne grasslands to examine mechanisms by which N. …

The structure of global invasive assemblages and their relationship to regional habitat variables: converting scientifically relevant data into decision relevant information
Quantitative methods for pest risk assessment combine sound statistical tools with sound ecological theory to convert scientifically relevant data into decision-relevant information. This thesis investigated a quantitative method for pest risk assessment called pest profile analysis (PPA). PPA is a …
