In last year's fires, Craig Anderson and Bindi Vanzella saw 120 trees burned on their Happy Wombat Hazelnut property.
Not only were some trees directly affected by fire, but the smoke and heat also severely affected other trees, seeing a dramatic drop in last season's harvest yield.
"Last year's crop was terrible," Craig said.
"In 2019, we harvested around six tonne of hazelnuts.
"Hazelnuts produce nuts bi-annually so you see a jump one year and it levels off the next.
"Last year the fire, heat and wind saw us only harvest two tonne.
"We also suffered from Brown Stain which is a climatic disease.
"We hadn't seen it before and it affected around 30 per cent of the crop.
"The nuts get to half size and then fall of the tree."
The Happy Wombat Hazelnuts crop was also affected by winged visitors as well.
Cockatoos and Crimson Rosellas have descended upon the hazelnut trees after their food was burned out in the fires.
As part of a plan with the NSW Department of Primary Industries, Craig and Bindi agreed to let the trees go and see what happened.
"We have seen a 95% survival of the trees," Craig said.
"The trees aren't grafted and have come back as they were.
"We have been able to re-grow the suckers from the base and it looks likely we will get a crop from them in four years.
"Even if the top has died, the roots survived and the tree has pretty much 're-set'.
"This has been a very good result for us as it will produce nuts much faster than planting a new tree would.
"Some suckers are seven foot tall and may provide nuts in two years!
"This study has also given the DPI invaluable information on how hazelnuts regenerate which they didn't have."
