Marine Protected Area Review | PAGE 2
Scope This report provides an overview of marine protected areas (history plus global, national and local Victorian context), reviews their scientifically reported conservation benefits, and briefly discusses the criteria that make for an effective marine protected area. It does so by analysing the scientific literature on marine protected areas in a conservation context, not their cultural, social or economic benefits. The report’s emphasis is on Victoria’s marine protected area network, but its 24 marine national parks and sanctuaries and six partially protected areas are Victoria’s contribution to the National Representative System of Marine Protected Areas (NRSMPA), which was agreed to by all Australian governments in 1998. Methods The scientific literature search for this report was not as thorough as a full systematic review, however it initially considered over 1600 scientific, government and NGO reports. To identify relevant scientific literature, searches were conducted on Web of Science, Science Direct and Google Scholar database for scientific research articles, reviews and short communications containing “Marine Protected Area” or “Marine Park” or “Marine Reserve” in the title, published between 2009 and 2018 (up to Aug 2018). Papers were filtered to include only studies that explicitly considered or evaluated the conservation benefits or success of MPAs. This process removed all studies which were either a) purely observational science (no comparison to non-MPAs), b) methodological only, c) attitudinal or focused on perceptions of MPAs, d) social or economic impacts e) management and enforcement, and f) purely theoretical. The most relevant 85 of these articles are referenced here. Statistics for the global coverage of MPAs were sourced from two main sources: Protected Planet marine database (UNEP-WCMC and IUCN 2018) for total MPA area, and Atlas of Marine Protection (Marine Conservation Institute 2018) for highly protected (i.e. no- take) MPA statistics. Australian MPA area statistics were sourced from the CAPAD 2016 database Australian Government Department of the Environment and Energy (2017) and supplemented by calculations from GIS maps of the 2018 Commonwealth MPA revisions Australian Government Department of the Seahorse, Port Phillip Bay.

This and most remote locations. New issue is further explored below. The broad goal “to achieve long-term tools were required to conserve the conservation of nature” is what sets world’s oceans. Hence over the past All MPAs are not equal MPAs apart from other marine spatial twenty years we have seen the global management tools which focus coverage of MPAs increase from Each MPA can differ significantly in on protecting ecosystem services below 0.7% of the world’s oceans in the rules and regulations in place to or cultural values. For example, 2000, to 7.44% today (UNEP-WCMC achieve marine conservation. The a fisheries habitat or spawning and IUCN 2018).

Ninety-four ecosystems, which also provide a foundation percent of global MPAs allow fishing for environmentally and culturally compatible of some kind in some areas (Costello spiritual, scientific, educational, recreational and and Ballantine 2015), and many do visitor opportunities not have no-take zones at all. For example, whilst Brazil’s MPAs cover III National Areas set aside to protect a specific natural 25% of their waters there are no areas Monument monument, which can be a landform, sea mount, that prevent fishing altogether (Giglio submarine caverns, geological feature such as et al. 2018).

There is currently much conjecture over the effectiveness of many MPAs globally, which exist only as lines on the map, without regulation or action on the water (Watson et al. 2014). For example, a 2012 report found that only 1% of MPAs in the Coral Triangle (SE Asia) were effectively managed (Burke et al. 2012), and hence could enforce regulations and address threats. MPAs with adequate staff capacity have 2.9 times the ecological impact, highlighting the need for adequate investment in MPAs beyond their initial establishment (Gill et al. 2017).

In preserving tolerance within the population to has the potential to reduce boat strikes natural food webs and trophic disturbance, and ability to recover on threatened species such as turtles balance, MPAs can also help resist under a variety of changed conditions (Denkinger et al. 2013).

Photo taken by Nicole Filby (Gomez et al. 2017). at the southern end of Port Phillip Bay. Protection from fishing under MPAs can, however, have unintended negative consequences for some protected species through trophic cascades. Abundance of the protected White’s seahorse in NSW MPAs were lower than outside, attributed to the higher abundance of predators in the MPAs (Harasti et al. 2014). Protection had resulted in the increase in exploited species, but not in non-exploited species that are threatened by external pressures that MPAs cannot effectively mitigate. Similar negative effects of protection were observed in an Indonesian MPA, where over-abundant turtles caused loss of seagrass habitat through overgrazing (Christianen et al. 2014), however this effect may be facilitated by the failure to curb threats on turtle predators. These results do not discredit MPAs however, they instead enforce the call for MPAs to be used in tandem with other approaches to achieve effective marine conservation.

SECTION THREE Global targets: how is Australia and Victoria tracking? International benchmarks as no-take MPAs, but set no deadline regional scale rather than the scale to achieve the target, instead seeing of single MPAs (Mach et al. 2017). Global targets for MPA coverage have it as an ambitious end-goal (WPC been in place since 2006, when the 2014), similar to the IUCN World In recent research by O’Leary et. Convention on Biological Diversity Al, (2016) , the authors analysed Conservation Congress in Hawaii called for MPAs on 10% of the world’s (2016), which recommended at 144 studies to determine oceans by 2012. However, this target whether international targets least 30% in MPAs with a long-term was not met and by 2012 only 2.3% for marine conservation were ambition that it be all no-take. of the global ocean was designated ‘adequate to achieve, maximize, or MPAs (Spalding and Hale 2016).

The 2014 World Parks Congress called for 30% of the world’s oceans to be managed 1 The six goals are: (1) protect biodiversity; (2) ensure population connectivity among MPAs; (3) minimize the risk of fisheries/population collapse and ensure population persistence; (4) mitigate the adverse evolutionary effects of fishing; (5) maximize or optimize fisheries value or yield; and (6) satisfy multiple stakeholders (i.e., studies contain analyses designed to identify the required percentage coverage to minimize trade-offs between stakeholders and maximize value.
