Shoreline Habitat

The Habitat Type provides a sim plified picture of the "look" of the unit overall, based on the detailed biophysical attributes that havebeen m apped. The Habitat Type category is a sum m ary of the observations of both the unit's biologial and geom orphologicalfeatures.Each Habitat Type has a definition that includes the typical substrate, wave exposure and biobands. For exam ple, for theSem i-exposed, Im m obile substrate Habitat Type, 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 Type determ ined?Each Habitat Type has typical biological features (including both an indicator species list and typical associated biobands). To determ ine the Habitat Type, 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 Type that best describes the unit.The Habitat Type 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. The sim plified category describes the features of the whole unit. Habitat Type 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
