Kelp forests are recognized as biodiversity hotspots and ecosystem engineers, while the macroinvertebrates linked with their holdfasts serve markers of pollution ecological environmental change. Notwithstanding evident economic importance this system, no research has been undertaken in South Africa to examine macroinvertebrate community assemblage patterns within Ecklonia radiata holdfast, nor mechanisms driving observed distribution patterns. This study identified compared holdfast-associated across several sites using univariate multivariate approaches, delineated physical factors influencing invertebrate organization. The key findings indicated that abundance exhibited little variations among sites, Dwesa presenting highest average Kob-Inn lowest. Mazeppa greatest species richness, succeeded by Nqabara. Beta diversity measured 0.42, turnover nestedness contributing equally. Xhorha Nqabara largest local contribution beta (LCBD) regarding turnover, whereas demonstrated LCBD terms nestedness. Substantial clustering was observed, each site harbouring a distinct macroinvertebrates. Species discriminated were Zeuxoides helleri, Cirolana venusticauda Amphipholis squamata.
