T h e Habitat T y pe provides a sim plified picture of th e "look" of th e unit overall, based on th e detailed bioph y sical attributes th at h avebeen m apped. T h e Habitat T y pe category is a sum m ary of th e observations of both th e unit's biologial and geomorph ologicalfeatures.Each Habitat T y pe h as a definition th at includes th e ty pical substrate, wave exposure and biobands. For exam ple, for th eS em i-exposed, Im m obile substrate Habitat T y pe, part of th e definition of th at class is a certain com bination of th e most likely biobands and indictor species present at a bedrock sh oreline with no mobile sedim ent present. How is Habitat T y pe determ ined?Each Habitat T y pe h as ty pical biological features (including both an indicator species list and ty pical associated biobands). To determ ine th e Habitat T y pe, th e biom apper looks at th e along-sh ore U nits as designated and described by th e ph y sical m apper, and1.records th e observations of th e biobands in th e unit and looks for indicator species, 2.assigns a bio-(wave) exposure category, 3.reviews th e ph y sical m apped inform ation, and 4.assigns th e Habitat T y pe th at best describes th e unit.T h e Habitat T y pe is based on th e wh ole unit and is sim ilar to th e ph y sical m appers use of th e ‘Coastal Class’ category, in th at th edetailed across-sh ore data are sum m arized into one attribute. T h e sim plified category describes th e features of th e wh ole unit. Habitat T y pe is a sum m ary of th e bioph y sical classification of th e wh ole sh ore unit, based on:•th e biobands observed, •th e wave exposure as indicated by th e bands, and •th e substrate ty pes in th e unit.Legend DefinitionsCC - Coastal Classification num berW ave ExposureE - Exposed - V ery h igh wave exposure, open ocean swellsm usually fetch es >500kmV E - V ery Exposed - Extrem e h igh wave exposureS E - S em i Exposed - High wave exposure, open sh orelines, areas between fully exposed and more sh eltered, usually fetch es 50 to 500kmP - P rotected - Low wave expsoure, sh eltered inlets, usually fetch es less th an 10kmS P - S em i P rotected - Moderate wave expsoure, partly sh eltered, usually fetch es 10-50kmV P - V ery P rotected - V ery low wave exposure, feth ces < 1km , sh eltered anch orages at h eads of bay s and inletes
