Reducing wildfire risk

Wildfire Investigator Jeff White says many of New Zealand's winegrowing regions can anticipate hotter and drier weatheer in the El Niño summer, particularly in eastern areas.

That risk has been exacerbated by good vegetation growth in wet winter and spring conditions, he says "This can lead to a build-up of fuel for potential wildfires."

Rising global temperatures associated with climate change also increase the potential for out-of-control fires.

"Hotter conditions can dry out vegetation, making it more susceptible to ignition and creating ideal conditions for wildfires to start and spread."

To mitigate the risks associated with wildfires in or around vineyards, vineyard owners and managers are advised to ensure the development of firebreaks and defensible space before conditions dr out.

Ensure 'hot' areas of machinery are kept clear of dry vegetation, with daily inspections part of the daily pre-work procedures, Jeff says.

Any activities that could create a spark should be limited to cooler periods of the day, with a water source on-hand to quickly deal to any fire starts.

And be aware of "spike days", he adds."These are days of extremely hot, dry, and especially windy conditions where wildfire potential is at its greatest."
