The EUNIS classification refers to "biogenic habitat" but the EMODnet Seabed Habitats agreed to "refer to "biogenic substrate" to highlight that this is specifically about substrate-modifying features."
"Biogenic substrate strictly refers to beds or reefs of a species that meet similar criteria to Mediterranean Posidonia oceanica meadows" (seagrass meadows) meaning that they:
- Cover and replace the underlying substrate as a structuring factor, so that the underlying substrate cannot always be detected
- Can occur on different substrate types, so that the underlying substrate is difficult to infer
- Are detectable using acoustic survey techniques, so that they are typically mapped in the same way as other substrate types
