Shoreline Habitat

102P.090

The Habitat Type provides a simplified picture of the "look" of the unit overall, based on the detailed biophysical attributes that havebeen mapped. The Habitat Type category is a summary of the observations of both the unit's biologial and geomorphologicalfeatures.Each Habitat Type has a definition that includes the typical substrate, wave exposure and biobands. For example, for theSemi-exposed, Immobile substrate Habitat Type, part of the definition of that class is a certain combination of the most likely biobands and indictor species present at a bedrock shoreline with no mobile sediment present. How is Habitat Type determined?Each Habitat Type has typical biological features (including both an indicator species list and typical associated biobands). To determine the Habitat Type, the biomapper looks at the along-shore U nits as designated and described by the physical mapper, and1.records the observations of the biobands in the unit and looks for indicator species, 2.assigns a bio-(wave) exposure category, 3.reviews the physical mapped information, and 4.assigns the Habitat Type that best describes the unit.The Habitat Type is based on the whole unit and is similar to the physical mappers use of the ‘Coastal Class’ category, in that thedetailed across-shore data are summarized into one attribute. The simplified category describes the features of the whole unit. Habitat Type is a summary 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 numberW ave ExposureE - Exposed - V ery high wave exposure, open ocean swellsm usually fetches >500kmV E - V ery Exposed - Extreme high wave exposureSE - Semi Exposed - High wave exposure, open shorelines, areas between fully exposed and more sheltered, usually fetches 50 to 500kmP - P rotected - Low wave expsoure, sheltered inlets, usually fetches less than 10kmSP - Semi P rotected - Moderate wave expsoure, partly sheltered, usually fetches 10-50kmV P - V ery P rotected - V ery low wave exposure, fethces < 1km, sheltered anchorages at heads of bays and inletes
