Why are MPA’s needed?
Many fisheries in decline or on verge of collapse
Coastal development has impacted marine ecosystems
Conflicting uses (fisheries / diving etc)
Most cost-effective to protect all parts of ecosystem (land/marine etc)
Are MPA’s really a solution or just another headache?
Challenges of MPA’s
Animals move, individual habitats vary, environmental conditions
change
Trying to put MPA’s along a ‘stepping stone’ route is difficult, we
need to do a better job of linking MPA’s
Economic hardships and safety issues amongst fishing community
Monitoring is extremely difficult (a lot of area to cover), regulation,
enforcement, etc. Monetarily expensive
Not all MPA’s are created equal

No-take reserves
Lowest is State Marine Parks (SMPs)

protection
State Marine Recreational Management Areas (MMAs)
Even fewer restrictions, geared towards allowing recreation while also
conserving
