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
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
Representational
Areas - types of MPAs
Percentage
Ecosystem
Identification
20-50% of each
ecosystem type
should be
protected for longterm viability
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

Study on local involvement in Mediterranean
(Badalamenti, 2000)
Success is proportional to the involvement of the
local community

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%
