Marine Habitat Classification for Britain and Ireland (22.04): Overview of changes since MHCBI 15.03 2023


This document provides an overview of all changes in the current Marine Habitat Classification for Britain and Ireland (version 22.04) since the previous version (15.03).

The update to version 22.04 involved the addition of five new biotopes and revision of some existing biotopes in the Sublittoral Sediment section of the classification. Edits to biotope codes as a result of species' name changes were made to the whole classification where applicable.

Please note: the original version of this document (published 11 May 2022) has been replaced with an updated version (19 May 2022) to fix a spelling mistake in one of the new biotope codes – SS.SMu.CMuSa.Ooph should read as SS.SSa.CMuSa.Ooph. This document was further updated in January 2023 to reflect changes to the description of SS.SCS.CCS.SpiB.
