Panel 3: How Can MPAs and Networks of MPAs Ensure Threat<br />

Mitigati<strong>on</strong> to Cetaceans?<br />

C<strong>on</strong>vener and coordinator: Sim<strong>on</strong>e Panigada<br />

Rapporteur: Christine Gabriele<br />

Objectives:<br />

<str<strong>on</strong>g>The</str<strong>on</strong>g> general aim of this panel was to c<strong>on</strong>sider whether existing MPAs and MPA<br />

networks provide sufficient protecti<strong>on</strong> for marine mammals. A number of specific threat<br />

factors, al<strong>on</strong>g with the mitigati<strong>on</strong> measures that have been used to address them, were<br />

illustrated and evaluated. Panelists were also asked to c<strong>on</strong>sider how and whether broader<br />

nati<strong>on</strong>al acti<strong>on</strong> plans and regi<strong>on</strong>al c<strong>on</strong>servati<strong>on</strong> plans could be used to create more<br />

effective MMPA networks.<br />

Am<strong>on</strong>g the specific questi<strong>on</strong>s to be addressed were the following:<br />

• Do existing MPAs effectively protect marine mammals from ship strikes,<br />

bycatch, chemical polluti<strong>on</strong>, acoustic polluti<strong>on</strong>, prey depleti<strong>on</strong>, and habitat<br />

degradati<strong>on</strong>?<br />

• What elements need to be included in management plans to ensure that MPAs<br />

are achieving their goals?<br />

• What methods are available to characterize, assess, and manage synergistic<br />

effects?<br />

• Is critical habitat adequately identified and protected within existing MPAs?<br />

• What approaches are available to protect and manage critical habitat that is<br />

temporally and spatially dynamic?<br />

• How can multi-nati<strong>on</strong>al and high-seas MPAs be designed and managed?<br />

• What real-time tools are available to mitigate the risk of ship strikes in MPAs?<br />

Summary of Findings:<br />

A basic principle for ensuring that an MMPA or MMPA network is effective is<br />

articulati<strong>on</strong> of the management goals that address both ecological and socio-ec<strong>on</strong>omic<br />

dimensi<strong>on</strong>s. Objectives should be clear, achievable, and measurable. <str<strong>on</strong>g>The</str<strong>on</strong>g> success of any<br />

MMPA is founded <strong>on</strong> scientific understanding of the ecology and critical habitat of key<br />

species and awareness of human activities and potential threats. Science should, am<strong>on</strong>g<br />

other things, seek to understand the physical mechanisms that cause formati<strong>on</strong> and<br />

persistence of biological “hotspots,” focusing <strong>on</strong> patterns and processes such as<br />

retenti<strong>on</strong> z<strong>on</strong>es, bathymetric gradients, and upwelling. New design c<strong>on</strong>cepts, including<br />

dynamic boundaries that can be changed in “real time” and extensive buffers, should be<br />

c<strong>on</strong>sidered where appropriate. Periodic reassessment and re-evaluati<strong>on</strong> of objectives and<br />

effectiveness, both internally and by interdisciplinary panels of outside peers, is<br />

recommended. Establishing and maintaining public acceptance of an MMPA is<br />

accomplished through good stakeholder relati<strong>on</strong>s and a broad-based educati<strong>on</strong> program.<br />

All aspects should incorporate c<strong>on</strong>siderati<strong>on</strong> of local, traditi<strong>on</strong>al knowledge.<br />
