Coral and Sponge Important Areas in West Coast Vancouver Island Ecoregion

Important Areas for coral, sponge, and reef-building species in the West Coast Vancouver Island ecoregion, mapped to inform the selection of marine Ecologically and Biologically Significant Areas. Data collection involved expert assessment based on criteria like Uniqueness, Aggregation, and Fitness Consequences. Initial assessments were conducted from 2004-2005 for the PNCIMA region, with subsequent efforts in WCVI and SOG in 2009.

Use Cases

• Map Important Areas based on Uniqueness, Aggregation, and Fitness Consequences criteria to support marine spatial planning.
• Analyze spatial overlap between coral and sponge Important Areas and other marine features to identify conservation priorities.
• Use geospatial data in formats like GEOJSON and ESRI REST to model habitat suitability for reef-building species in the WCVI ecoregion.
• Integrate this layer with datasets on birds, cetaceans, and fish to conduct a multi-species ecosystem assessment for the region.

Strengths

• Data is part of a formal science advisory process for identifying Ecologically and Biologically Significant Areas under Canada's Oceans Act.
• Includes project documentation and technical reports detailing the assessment methodology and its role in EBSA selection.
• Covers multiple marine ecoregions including West Coast Vancouver Island, Strait of Georgia, and the Pacific North Coast Integrated Management Area.

Limitations

• Assessment methods, scientific advisors, and temporal extents may differ between the 2004-2005 PNCIMA effort and the 2009 WCVI/SOG efforts.
• Data collection is considered complete, but the emergence of significant new data may require case-by-case revisiting, indicating potential staleness.
• The dataset is one of a series; a full ecosystem analysis requires joining with separate datasets for birds, cetaceans, fish, and other taxa.
