T he Habitat T ype provides a sim plified picture of the "look" of the unit overall, based on the detailed biophysical attributes that havebeen m apped. T he Habitat T ype category is a sum m ary of the observations of both the unit's biologial and geom orphologicalfeatures.Each Habitat T ype has a definition that includes the typical substrate, wave exposure and biobands. For exam ple, for theSem i-exposed, Im m obile substrate Habitat T ype, part of the definition of that class is a certain com bination of the m ost lik ely biobands and indictor species present at a bedrock shoreline with no m obile sedim ent present. How is Habitat T ype determ ined?Each Habitat T ype has typical biological features (including both an indicator species list and typical associated biobands). T o determ ine the Habitat T ype, the biom apper look s at the along-shore U nits as designated and described by the physical m apper, and1.records the observations of the biobands in the unit and look s for indicator species, 2.assigns a bio-(wave) exposure category, 3.reviews the physical m apped inform ation, and 4.assigns the Habitat T ype that best describes the unit.T he Habitat T ype is based on the whole unit and is sim ilar to the physical m appers use of the ‘Coastal Class’ category, in that thedetailed across-shore data are sum m arized into one attribute. T he sim plified category describes the features of the whole unit. Habitat T ype is a sum m ary of the biophysical classification of the whole shore unit, based on:•the biobands observed, •the wave exposure as indicated by the bands, and •the substrate types in the unit.Legend DefinitionsCC - Coastal Classification num berW ave ExposureE - Exposed - V ery high wave exposure, open ocean swellsm usually fetches >500k mV E - V ery Exposed - Extrem e high wave exposureSE - Sem i Exposed - High wave exposure, open shorelines, areas between fully exposed and m ore sheltered, usually fetches 50 to 500k mP - P rotected - Low wave expsoure, sheltered inlets, usually fetches less than 10k mSP - Sem i P rotected - Moderate wave expsoure, partly sheltered, usually fetches 10-50k mV P - V ery P rotected - V ery low wave exposure, fethces < 1k m , sheltered anchorages at heads of bays and inletes
