Climate change is likely to have direct impacts on the natural ecosystems and species of NSW, however a secondary impact is expected to be the increasing prevalence of weeds, pests and diseases. The shifts in temperature and rainfall patterns and the increase of extreme weather events is likely to change the ability of pest species, weeds and pathogens to move into different areas and locations, threatening the native wildlife.
The projects of this theme focused on research which identifies risks from potentially emerging diseases and weeds under future climate conditions. This research is critical for the early detection, exclusion and eradication of exotic pests and pathogens, which is more cost effective than post-outbreak controls. In addition, early identification enables the development of management protocols and will support biosecurity officers, policy makers, conservation managers and scientists, to proactively manage weeds and pathogens in NSW.

A report on remote sensing for monitoring of the distribution of several weed species in the alpine region of NSW, specifically targeting Orange Hawkweed, Mouse-ear Hawkweed and Ox-eye Daisy (as requested by NPWS)
A decision-support tool providing the ability to interrogate individual profiles for over 500 non-native naturalised and invasive plant species within Australia and assess weed threats for regions of interest under current and predicted future climates
Interrogation of existing datasets and investigation of current disease outbreaks to predict the consequences of a warming climate for biodiversity. Wildlife health data from the Australia Registry of Wildlife Health was merged with other data sources and analysed to establish climate-disease links.
