%X Pattern analysis data are presented for a number of tree species populations sampled from two sites located in dry sclerophyll forest within the Ku-ring-gai Chase park of New South Wales. The distributions proved to be predominantly contagious or random, with regularity occurring only occasionally. Observed variations in the degree of aggregation exhibited by a species were taken into account in interpreting pattern analysis curves. The relation of pattern analysis data to sample quadrat data fitted to known mathematical models is extremely variable, and it is shown that pattern at block sizes other than the one under consideration may suppress the appearance of deviations from randomness at block sizes which do show contagion when sampled with randomly placed quadrats. The possible origins of contagious distributions in eucalypt forest are briefly discussed.
