Résumé :	Relationships between the surface features created by infaunal bioturbators and the diversity and structure of a macrobenthic community were identified at spatial scales of 30 to 100 cm for an area of shallow (10 m) subtidal sediment at Jennycliff Bay (Plymouth, UK) in May 2000. At spatial scales greater than or equal to 80 cm, macrofaunal heterogeneity, and diversity, was greater in areas that contained many different surface features compared with areas containing few features. This observation is field evidence to substantiate suggestions that the non-destructive quantification of conspicuous surface features is a useful surrogate of macrobenthic diversity. This surrogate may be most useful in assessing large scale impacts on sediment habitats such as faunistic changes over long distances, long-term temporal changes in a particular place or assessing differences between habitats or geographical locations.
