Jarrah dieback (Phytophthora cinnamomi) is an introduced soil pathogen that has been seen to cause severe damage to Western Australian forests for nearly 100 years.
GP Forestry is currently conducting unique field trials which uses the power of native soil bacteria to out compete the introduced pathogen.
The “Bactivate” trial in a Jarrah forest east of Harvey has been running for 3 years, results are promising with around 40% less new tree deaths (Banksia grandis) in treated sites as compared to the control. The trial is ongoing.
