Climate change affects weeds
The report: Climate Change and Invasive Plants in South Australia, used climate projections to 2080 to examine how weeds may shift in range across the State. Detailed profiles are provided for 13 weed species, including options for managing them under climate change.
Lead-author, Dr Darren Kriticos from CSIRO’s Climate Adaptation Flagship, said projections of future climate scenarios indicating higher temperatures and less rainfall on average in South Australia could have a dramatic effect on the distribution and abundance of weeds.
“Existing weed problems in northern areas of the State may shift further south. Landholders may have to deal with species where they have no past experience. In fact, we may be seeing a case of weed change,” Dr Kriticos said.
The report found that by heeding the early warning of projected climatic changes and using possible adaptation options there may be some positive news in terms of strategic weed management.
