Kelp holdfast assemblages
This dataset describes the biodiversity of fauna (including Arthropoda, Annelida, Mollusca, and Bryozoa) inhabiting kelp holdfasts in northeastern New Zealand at several spatial scales: from meters up to hundreds of kilometers.

Site Location(s): Berghan Point (34°55.78′ S, 173°32.72′ E), Home Point (35°19.38′ S, 174°21.38′ E), Leigh (36°17.43′ S, 174°48.82′ E) and Hahei (36°50.86′ S, 175°49.32′ E). Within each location, there were two sites (separated by hundreds of metres to kilometres), and within each site, there were two areas (separated by tens of metres and measuring approximately 10 m × 10 m).
Site(s) Georeferenced: No
Spatial Scale of data: individual kelp holdfast, 36-285 ml by volume
Frequency: single collection period (all collections took place between 7 January to 5 February)
Data Acquisition: Observational
Methods: Kelp holdfasts of the species Ecklonia radiata were collected according to a structured hierarchical experimental design. The largest spatial scale examined was locations (four levels, separated by hundreds of kilometres), which were approximately equally spaced along a large stretch of the north-eastern coast of New Zealand (See Anderson, M.
