Climate change represents an unprecedented challenge to the world’s biosphere and to the global community. It also represents a unique challenge for plant health. Human activities and increased market globalization, coupled with rising temperatures, has led to a situation that is favourable to pest movement and establishment. This scientific review assesses the potential effects of climate change on plant pests and consequently on plant health. The evidence assessed strongly indicates that climate change has already expanded some pests’ host range and geographical distribution, and may further increase the risk of pest introduction to new areas. This calls for international cooperation and development of harmonized plant protection strategies to help countries successfully adapt their pest risk management measures to climate change.

Any unusual plant pest, disease or weed should be reported.
Reporting hotlines operate in both Australia and New Zealand (numbers shown below).
Australian Exotic Plant Pest Hotline
New Zealand Pest and Disease Hotline
Pests can also be reported using apps, such as MyPestGuide® for Australia, that allow you to submit a photo of the pest or symptoms.
Every report is taken seriously and handled confidentially. Management of calls varies in different areas, but to the same end.
The PSNAP program is currently being transitioned to the Australian Government Department of Agriculture, Fisheries and Forestry (DAFF).
During this time, content will not be updated and membership requests may take longer to process.
Thank you for your patience and support while we complete this transition.
