Abstract Aim Vegetation change such as woody encroachment is characterised by changing species interactions, and processes competition facilitation may be inferred from patterns of association between juveniles mature individuals different species. Our aim was to apply evaluate rules analysis (ARA), a rule‐based data‐mining technique more commonly known market basket analysis, novel tool examine the associations in demographic stages along thicket gradient. Location The research conducted subtropical thicket–savanna mosaic (730 mm mean annual rainfall) Eastern Cape, South Africa. Methods We used space‐for‐time substitution approach sampled plants size classes at sites representing early, intermediate late encroachment. All were recorded occurring singly or unique clumps. ARA determine which common overall, than expected, each three stages. Results most important indicated that Vachellia karroo recruited large numbers open grassland and, once mature, provided nucleation for small suite dominated Scutia myrtina . In later stages, multiple diverse found increasingly Conclusions sampling proved useful characterising species‐size class associations, illuminating interactions recruitment clump formation sequence. studies vegetation change, can complement multivariate analyses composition reveal specific it provide less laborious alternative point‐pattern elucidating spatial associations.
