. Using artificial data, techniques that have been proposed for analyzing multiple species pattern in vegetation, are compared. No single method was capable of detecting, clearly and unambiguously, all scales of pattern in all cases, and the effectiveness of the different methods was found to depend on the scales of pattern of the component species and on how the patterns of individual species are combined. Some improvements for the application of the popular multi‐scale ordination method are suggested. Several sets of field data are analyzed and the results used to illustrate a discussion of the existence and nature of multi‐species pattern in vegetation and how it is to be evaluated.
