
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.

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
MPA LINKS
Square = No
Take Zone
(NTZ)
Line = links
(connection
between
zones)
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

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

Adjacent Fishing
Areas
 Florida (Taylor et al. 2000)


Tagged fish left MPA to enter fishing grounds
Several world records set near MPA
 Caribbean (Taylor et al. 2000)

Greater abundance, size, and biomass near MPA
 California (Thompson 1997)

Median catch close to MPA significantly greater than median catch far
from MPA
 Gulf

of Mexico (Jones 1998)
No increase in yield, but compliance by fishers only 65%
MPAs in BC
 Whytecliff
