Description: A survey of the subtidal physical and biological features of the VEHEAP Harbours area (Victoria and Esquimalt Harbour, Gorge and Portage Inlet and Esquimalt Lagoon) with the intent of mapping the general distribution and position of physical and biological features for both inventory and harbour management purposes. The distribution of red sea urchins (Strongylocentrotus franciscanus) on the seabed based on visual classification of each second of the video imagery as well as subsequent dive survey verification. Red sea urchin distribution is mapped in one of two distribution categories, few to patchy and continuous to dense. These urchins are found on rocky substrate in the intertidal zone to deeper subtidal depths. Urchins graze on both attached and drift algae and often create "urchin barrens" which become devoid of marine vegetation.

The distribution of oysters on the seabed based on visual classification of each second of the video imagery as well as subsequent dive survey verification. Oyster distribution is mapped in one of two distribution categories, few to patchy and continuous to dense. Native or Olympia oyster, Ostrea conchaphila, is found primarily in the Gorge Waterway and Portage Inlet. This oyster grows on hard substrate (rock, man-made debris) in the Gorge but is found growing on clumped oyster shells in Portage Inlet where the substrate is silty sand. The Japanese or Pacific oyster, Crassostrea gigas, may also be present in the shallow subtidal but this larger species is more common in the intertidal zone in the harbour areas.

Description: Estuary Ecosystem Units for Portage Inlet, Gorge Waterway, Victoria Harbour, Equimalt Harbour, and Esquimalt Lagoon. Feature based metadata part of attrbute table. Collection methodology and database description to folllow at the later date.
Description: A survey of the subtidal physical and biological features of the VEHEAP Harbours area (Victoria and Esquimalt Harbour, Gorge and Portage Inlet and Esquimalt Lagoon) with the intent of mapping the general distribution and position of physical and biological features for both inventory and harbour management purposes. Locations where videos where taken.
Description: Dataset created by Archipelago Marine Research Ltd. The intertidal zone is depicted as a uniform 15m wide band extending 10m seaward and 5m landward of the shoreline. The actual width of the intertidal zone is highly variable throughout the harbours area, however a representative width was selected in order to represent intertidal features at usable, practical mapping scales. Intertidal shore type, marine influence, intertidal biobands and overall ecological rating for each shore unit are mapped on this band.

Description: Dataset created by Archipelago Marine Research Ltd. A Shore Unit is a section of shore of uniform physical form (e.g. beach) and substrate (e.g. gravel) in the upper and mid-intertidal zone. Shore units were taken from initial shore classification of the harbours area by the BC Land Use Coordination office in 1989 and updated by field observations in 1998 and 2002. _SUINDEX is a number which designates a discrete shore unit. Shore Units are labeled sequentially from Ogden Point, Victoria Harbour counter-clockwise through Victoria Harbour to Macaulay Point, then from Duntze Head, at the east entrance to Esquimalt Harbour, counter-clockwise to Fisgard Island and west through Esquimalt Lagoon.

Description: A polygon feature representing a drainage area where all surface water in that area drains to a single location.
Layer showing watershed catchments that drain into the VEHEAP area (Victoria Harbour, Gorge Waterway, Portage Inlet, Esquimalt Harbour, Esquimalt Lagoon).
