Marine Corridor Planning
Marine Corridor Planning
The underlying principles for terrestrial and marine biodiversity
conservation and corridor planning are often similar. However, it is
imperative to take into account a number of crucial differences in
ecosystem processes in order to best inform these principles.
Successful management and conservation of marine species and areas
will require a comprehensive knowledge of terrestrial and marine
The areas of focus and study are similar for both systems:
- Biological/Ecological
- Sociological
- Governance
- Political and Legal
- Economic
- Business models
Marine Considerations
The main differences between marine and terrestrial conservation strategies
concern the relative importance of ecological processes.
 Pelagic distribution of larvae require potentially different models
Threat Differences
 Overexploitation
 A major threat for majority of marine species, reflecting in entire
 Fishing pressure: predominate threat but we have very little
knowledge regarding impact of fisheries / capacity to deal with threat
 Fragmentation
 Needs to be addressed in separate context, not comparable to
terrestrial threat level
 Pelagics generally unaffected by fragmentation—still have long
distance dispersal
 Mostly affects mobile benthic species at finer site scale
Marine Considerations (cont.)
 Species distribution scale for defining endemism is much greater for
marine than terrestrial systems (exception being limited range species
endemism for island and seamount areas)
Ecological biomes and boundaries
 Hard to define spatial units due to mobility and fluidity
 Larvae don’t necessarily rely on benthic habitat -- strong
interdependence between systems
 Dynamic and transitional boundaries
Ownership of ocean: coastal, economic exclusive zone (EEZ), high seas
 Vertical and seasonal
 Aggregations of populations for spawning very common
Questions to Address
Define marine wilderness areas/hotspots
 How do we define these? Where are they? What do they look like?
 Example: are there deep sea wilderness areas/hotspots? No
people but high impact
 Don’t have marine “Amazons” or “Saharas” defined yet
Data (estimated to have 5% of the amount of terrestrial data)
 How much is enough for species and habitat?
 How do we move forward in the absence of an abundance of data?
KBA criteria/thresholds and monitoring habitat change/indicators
 Current approaches and similarities/differences to marine systems
Identify context analysis gaps
Marine Corridor Planning Process
Guiding marine strategy
 Focus on species, however, we need to concentrate on processes
in order to build the strategy
 Can’t concentrate effort on distribution of species alone
Institutional responses should be based on our global expertise
 Essential to get buy-in and local experience from marine field staff
Need for more data and capacity to adopt/modify terrestrial corridor
concepts for marine ecosystems
Connection and consideration of land-sea interfaces
Use this corridor workshop as platform for marine process in near
 Build upon similar concepts and identify and articulate differences
Current Initiatives to Address
Marine Corridor / Large Scale System Questions
Monitoring specialist
 Habitat change and indicator analyses
Conservation Synthesis Marine Specialist
 KBA criteria and thresholds
Oceanographer– Large Scale/Habitat Specialist
 Integration of biological/ecological and physiographic and
oceanographic concepts
MPA Science Center
 Study and application of MPA science to network/corridor
conservation planning
Current Initiatives to Address
Marine Corridor / Large Scale System Questions (cont.)
Learning from ongoing field projects and programs
Collaboration with other CI departments
 Example: CABS Human Dimensions dept-- socioeconomic
issues relating to links between terrestrial and marine
Marine Web Portal
 Capitalize on little information and limited capacity to create
 Quickly share lessons learned, coordinate information,
reduce overlap, and internally enable our marine experts all
over the world to communicate on this topic
