Southern Gulf Islands Marine Protected Area
Federal Level National Marine Conservation Area Proposed Sites in BC Southern Gulf Islands National Park
Bill C-10 National Marine Conservation Areas Provides for Marine Protected Areas
Bill C-10 Canadian Parks and Wilderness Society (CPAWS)- Proposal for Bill C-10 Canada National Marine Conservation Areas Act, October Provide Canadians with special places to connect with the rich and diverse environments on our shores, and ensure lasting benefits to our coastal communities and the ecological integrity and healthy proliferation of the valuable marine environments.
Biodiversity Marine Protected Areas (MPA) = No Take Zones (NTZ) Oceans Act Size Connections Representative Areas references - (Mosquera et al. 2000, Polacheck 1990, Russ et al. 1989, Roberts 1997; 1998, Ballantine, 1997)
Oceans Act MPA Criteria: (1) High biodiversiy (2) Fish and habitat (3) Threatened (4) Unique habitat S. Gulf Islands: (1) Nutrients upflow (2)Rockfish,lingcod (3) Killer whales (4) Sponges, sea anenomes
Proposed MPA Sites 1. Southern Gulf Islands 2. Gwaii Haanas 3. Scott Islands 4. Queen Charlotte Strait 5. Hakai 6. Gabriola 7. Race Rocks 8. Bowie Seamounts 9. Endeavour Hot Vents

Map
Size of No Take Zones (MPA) Small areas - few kilometers wide, for small animals (Roberts and Haukins 2000) Large areas - tens of kilometers wide, for larger animals and bird colonies (Mosquera et al. 2000) Borders - low surface area (Roberts et al. 2001) Buffer zones - to protect core NTZ centers
MPA Connections Distance - No take zones should be 10 to 50 km apart to maximize biodiversity protection Currents - link no take zones Upstream - need to be protected to conserve downstream areas Arrange - to maximize links between No Take Zones
Square Line Square = No Take Zone (NTZ) Line = links (connection between zones) MPA LINKS
As the number of no take zones increase, the conections double and triple between these protected areas
The overall protected areas increase in size because of the increased number of links between protected sites
Representational Areas - types of MPAs Percentage 20-50% of each ecosystem type should be protected for long- term viability Ecosystem Identification Topography / ocean features Exposure High and low tidal exposed areas consist of different species
Biodiversity Protection Summary Small - few kilometers for nonmoving species Large kilometers for mobile animals 20% - of each habitat type Research - a survey over time to identify best design for maximum biodiversity
