MPA Definition

The International Union for Conservation of
Nature and Natural Resources (IUCN) defines
marine protected areas (mpas) as:
“any area of intertidal or subtidal terrain,
together with its overlying water and associated
flora, fauna, historical and cultural features,
which have been reserved by law or other
effective means to protect part or all of the
enclosed environment” (Kelleher and
Kenchington 1992)

General Observations

In Pacific Canada, most existing marine protected areas)
are provincial (116, 94 %), nearshore and relatively
small. 66 (52%) are less than 1 km2 in area

In eastern and arctic Canada, most marine protected
areas are federal (62, 78%), and most are Marine Bird
Sanctuaries (MBSs)
MBSs in eastern Canada are relatively small in area
(average marine area, when present = >5 km2) and
focus on migratory staging areas, but those in the Arctic
are large and focus on breeding grounds, with marine
portions averaging 898 km2

Restrictions on Human Activities
Three basic groupings of protection:
1) prevention of habitat destruction or modification [e.g.
non-renewable resource extraction (water diversion,
mining, etc), ocean dumping and dredging, etc.]
2) prevention of species harvest or exploitation (i.e.
logging, fishing or hunting, and restrictions are often
species specific);
3) prevention of species’ disturbance (e.g. feeding wildlife,
or interfering with their natural behaviour, reproduction
and rearing of young)
Zoning within mpas

All current mpas in Canada are uniform, or homogenous, in
the protection that is provided. There is no internal zoning in
any whereby greater or lesser protection is legislatively
provided.

Some MPAs and most, if not all, NMCAs, when they are
established, are likely to be internally zoned, with some areas
likely being “no take” areas, i.e. closed to all fishing activity.

Because marine species are already extensively exploited,
“no take” areas near urban areas are likely to be relatively
small, meaning that particular attention will need to be
directed to defining rationales and objectives, and in linking
them into a network so that synergistic conservation benefits
are obtainable.
Fishery Closures

In BC, for example, there were 579 spatially-persistent
fishery closures in 1997 which restricted fishing activity
 Some overlapped the region’s 125 legislated marine
protected areas and seven pseudo marine protected
areas, but many did not.
 The problem with fishery closures as a tool is that
protection established through regulation is relatively
dynamic, with regulations relatively easily created,
modified or deleted on an annual basis. Databases
describing them also need to be updated frequently to be
accurate and current, which can be tedious and require
committed resources.
A Functional MPA Network Does
Not Yet Exist in BC
•
•
•
•
At present, while there are many BC mpas, their spatial
locations, sizes and extent of protection applied have not
been developed in a coordinated manner
There is no functional mpa network - each mpa’s
establishment was primarily considered on its own
merits, and not in terms of its contribution to an
overarching conservation agenda
Each agency established its own protected areas
independently of those being established by other
agencies
To address this, I later present a sample mpa network
design based on optimisation theory, using the analytical
program MARXAN
Approaches to Date

In the late 1990’s, DFO actively promoted development
of an MPA Establishment Strategy (see 2000 Federalprovincial MPA Strategy). It stalled in 2000, in part
because:
1) MPAs are part of an IM process, and the “tail was
moving faster than the dog” – implementation of the IM
process needed to catch up, and
2) lack of treaties with coastal First Nations
created13 political problems re MPA establishment.

In support of a science process, the following paper was
developed:

Current State
There is a diversity of legislation to establish
MPAs, but they need to be harmonised because
each legislation has limitations, and many do not
protect marine species, only the physical
substrate. To date this harmonisation has not
happened, although in the past few months, a
new MOU has been signed which should
facilitate this. There is a new push because BC
wants to develop offshore oil and gas, and it can
not do so politically without offering something to
environmentalists!
MEMORANDUM OF UNDERSTANDING
RESPECTING THE IMPLEMENTATION OF CANADA'S OCEANS
STRATEGY ON THE PACIFIC COAST OF CANADA
Canada and BC agree to develop subsidiary
memoranda of understanding or agreements on the
following:
a marine protected areas framework for the Pacific
coast that will aim for the coordinated establishment of
marine protected areas. Development of this
subsidiary memorandum of understanding will be led
by the Department of Fisheries and Oceans and the
Ministry of Sustainable Resources Management in
cooperation with Environment Canada, Parks Canada,
and Natural Resources Canada. It will outline
appropriate mechanisms, processes and structures to
coordinate the review and establishment of new
marine protected areas, and will include an
assessment of existing federal and provincial marine
protected areas;
Biological Valuation Criteria

Canada has just completed a process to identify ecologically and
biologically significant areas (EBSAs), which is a first step to identify
Canadian areas for enhanced management protection. Many of
these areas, but not all, are expected to be later identified as Areas
of Interest (AOIs), a first step in the establishment of MPAs.

The reality seems to be that the theoretical approach and complex
criteria discussed in the many papers discussed are proving to be
somewhat academic and operationally impractical to effect.

Much theoretical information desired is unavailable, e.g., detailed
abundance and distribution data on non-commercial species (i.e.
biodiversity), and data related to the connectivity of areas and their
importance in overall ecological processes.

We are thus hopeful that the EBSA approach, which I will present
later, is a way forward, in that it utilises the advice of experts
available now in an adaptive management process that can address
the threats that may cause significant impact, now and in the future.
MPA Network
In support of this process, a paper outlining
different objective optimization methodologies
was developed:

and S. Jessen. 2004. Evaluation of site selection
methodologies for use in marine protected area network
design. Canadian Stock Assessment Secretariat Res.

MARXAN

Marxan is a type of Complementarity model, which take into account
the extent to which a site, or set of sites, contributes to meeting the
desired objectives of the overall network. These programs stand out
from the more traditional scoring methods in that they seek to find
the most efficient solution to the problem of designing a network of
mpas that meets a specified conservation goal, while minimising the
‘cost’ (defined here as social, economic, implementation,
management, foregone opportunity, or any other type of quantifiable
cost) of the network (Stewart et al. 2003; Pressey et al. 1996;
Stewart and Possingham 2002).

Marxan utilises a simulated annealing selection process that begins
by generating an initial reserve system that consists of a completely
random set of sites. Next, it iteratively explores trial solutions by
making sequential random changes to the system. Either a
randomly selected site, not yet included in the reserve system, is
selected, or a site already in the reserve system is deleted
(determined by which choice has the least cost). At each step, the
new solution is compared wit the previous solution (i.e. it searches
for the least costly site in each iteration).

We need to also address what we
do not know…
Some marine datasets were hoped to completely cover the
study area, but actually do not …
Examples
• Depth (bathymetry): Some parts of some inlets
not covered -- usually the heads.
• Substrate: No data for greater than 1000 m
depth.
Strategy
• Explicitly note these No Data areas, and set
conservation goals (targets) for these as well,
using the precautionary principle to justify some
protection

Discussion
Pros
Most comprehensive spatial ecological analysis to date of the Central Coast,
North Coast, & West Coast of Vancouver Island.
 Efficient processing of a large mass of data of varying quality.
 Spatially explicit; transparent evaluation criteria; several variations of
solutions.
 Offers clear direction for a “first iteration” of MPA selection.

Cons
Many data gaps remain.
 Considers proximity, but not connectivity.
 Assumes ecosystem function, but does not test this (e.g. trophic links).
 Does not yet consider existing human usages.
 Only a little LEK, and no TEK incorporated to date.

Ecosystem Spatial Analysis (ESA)
ESA as a tool can…
•offer possible solutions / starting points for
marine planning in Integrated Management ~
e.g. Conservation Utility.
•roughly define the bounds of what is
“reasonable” ~ e.g. rockfish habitat modelling
•combine stakeholder input (LEK / TEK) with
scientific data ~ e.g. fishers use analysis.
•offer new insights than can lead to
management decisions ~ e.g. trawl bycatch of
corals and sponges
