This fall, President Obama signed a proclamation<\/a> that created the biggest marine reserve<\/a> in the world. By extending the protective boundaries around Wake Island, Jarvis Island and Johnston Atoll from 50 to 200 nautical miles, the Pacific Remote Islands Marine National Monument<\/a> netted a six-fold increase in area. Resource extraction – including marine mining and commercial fishing \u2013 is now prohibited. Protecting these 490,000 square miles is a huge step forward in supporting efforts for marine resource protection and sustainability in the Pacific.<\/p>\n

Due to improved fishing technologies, there are simply no natural refuges left in the oceans, only those we choose to establish and respect. Resources can be exploited from every depth, location, nook and cranny. Bottom dredges, trawlers, so-called fish finders that use SONAR to detect fish, SCUBA nighttime spear fishing, long-lining and cyanide used by some aquarium fish collectors have all contributed to the loss of resources at unsustainable levels. These techniques come with a high degree of collateral damage too, including by-catch.<\/p>\n

Savings accounts for marine life<\/h2>\n

Marine Protected Areas<\/a> are a proven tool<\/a> to address<\/a> such losses. When properly enforced, they serve to protect all the parts of a functioning marine ecosystem. Just as in human health, all of the parts need to be protected and in good functional shape. Great kidneys and lungs won\u2019t work if the heart or brain are missing. Likewise, a healthy marine ecosystem needs a balance of all trophic \u2013 or feeding \u2013 levels including a variety of primary producers, prey and predators and the supporting physical habitat.<\/p>\n

To use another metaphor, MPAs are like bank accounts; the fisheries resources contained within are the principal that produces interest in the form of offspring: larvae that become juveniles and eventually reproductive adults. The greater the principal in the form of fish stocks, the greater the interest which can be drawn sustainably in the form of caught fish. It is also notable that as the size of a mature female fish doubles, her reproductive capacity increases<\/a> up to a thousand-fold. Protecting the so-called BFFs \u2013 big fat females \u2013 raises the interest rate considerably, and is essential to the maintenance of fisheries stocks in large MPAs.<\/p>\n

Welcome to the neighborhood<\/h2>\n

Key considerations in the selection and design of Marine Protected Areas include location, size and connectivity. The recently designated areas for expanded protections in the Pacific Remote Islands are particularly well chosen for a number of reasons.<\/p>\n

From a human (not fish) perspective, these islands are indeed remote. Ranging hundreds to thousands of miles south and west of Hawaii, they\u2019re distant from land-based sources of pollution and sedimentation. The lack of resident human populations on these islands and their relatively minimal use make them low-hanging fruit in the search for locations that can be added to the world\u2019s inventory of MPAs. It\u2019s far more difficult to establish much-needed large protected areas where there are preexisting high levels of use.<\/p>\n

This expanded marine national monument contains a variety of ecosystems: deep ocean benthos, numerous seamounts, thriving coral reefs. It\u2019s home to rich phytoplankton and zooplankton populations that drive the entire oceanic food web, and populations of large migratory fish of economic, ecological and cultural value. The included island landmasses host millions of seabirds and provide nesting habitat for endangered species of sea turtles. It makes sense to protect areas that still have intact and thriving flora and fauna.<\/p>\n

Models of climate change impacts show an increase in the size and persistence of the western Pacific warm pool<\/a>, a body of the world\u2019s warmest waters that spans from the equatorial Pacific to the Eastern Indian Ocean. This is expected to cause migratory fish to move east and north, into the Pacific Remote Islands. Catch data demonstrates an increase in fish populations<\/a> in this region during El Ni\u00f1o years when sea surface temperatures rise. For this reason, the location of this Marine National Monument is especially important for the future.<\/p>\n

Not a cure-all<\/h2>\n

The establishment of large MPAs like those covered under Obama\u2019s recent proclamation is both scientifically defensible and critically important. But MPAs alone can\u2019t ensure resource sustainability into the future. Consider the kids’ game of tag: you\u2019re only safe when you\u2019re securely on base, and you\u2019re at risk of capture when you run from one base to another. Fishers are familiar with this as well; they\u2019ll simply line up<\/a> in the corridors of connectivity among MPAs to capture migratory species as they travel from one safe base to the next. To protect populations of fish as they move, regional MPA networks must include a number of these connection corridors.<\/p>\n

Finally, the expanded areas of protection, as with all MPAs, will be of no value unless there is effective enforcement. This will require sufficient dedicated financial, institutional and human resources to work. The tools are available, including vessel monitoring systems, observer programs, satellite surveillance and drone technologies. Marine spatial planning that identifies clear shipping lanes makes it easier to spot poachers, and with appropriate regional political will, it can be easy to impound such vessels coming into ports to offload or refuel.<\/p>\n

Still, only 2% of the world\u2019s oceans are under any kind<\/a> of protection, far less than the 30% recommended<\/a> by numerous marine scientists and policy makers. This goal is based on biological concerns about the loss of species, habitat and marine ecosystem sustainability, and the economic realities of documented overfishing and resource depletion in our oceans. Considering the impacts of global climate change on top of over-exploitation of fisheries resources and ongoing pollution, meaningful action is critical if we are to leave a legacy of healthy oceans and resources for future generations.<\/p>\n
