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 2000.

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.

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

SquareSquare = No Take Zone

(NTZ)

LineLine = 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 - 10-20 kilometers for mobile animals

20% - of each habitat type Research - a survey over time to

identify best design for maximum biodiversity
