This report presents the findings of broad scale mapping of
substrate (e.g., firm sand, soft sand, mud, gravel) and
vegetation (e.g., macroalgal beds, seagrass beds,
saltmarsh vegetation, exotic weeds) present in the intertidal
areas of both arms of the Porirua Harbour. The survey was
undertaken during December 2007, with habitat cover
recorded onto laminated aerial photographs and
subsequently digitised and entered onto GIS maps.
