Colour aerial photography at scales of 1:3000 and 1:6000 was used to identify 86.6% and 68% respectively of the 5.03 ha affected by Armillaria root rot in a 32 ha mixed species eucalypt stand, located in central Victoria. At the 1:3000 scale more of the infected area was detected and correctly mapped but a larger proportion of the healthy area was incorrectly classified as infected.
... Ground surveys during the fruiting season may aid accurate mapping of the distribution of A. luteobubalina in the high-rainfall zone of the E. marginata forest. Although disturbance can lead to a misclassification of healthy forest from large-scale aerial photography and an overestimate of the area infected with A. luteobubalina (Myers et al. 1983), this can be corrected after routine ground checking. The size in addition to the location of infection centres needs to be determined to quantify the proportion of E. marginata forest infected. ...
