"Two modifications to the Pacific Forest Research Centre root disease ground-survey method are described. Multiple-disease recording allows up to nine disease types to be recorded during a single survey. Separate analyses and disease area estimates are produced for each disease and for combinations of diseases. Post survey stratification of stands by infection intensity allows the stand to be subdivided into compartments or blocks with differing intensities. Separate analyses and disease-area estimates are produced for each block. Data preparation for each modification is described and examples are given"--Summary, page 3.
