摘要
1. Through recent Decisions of the Convention on Biological Diversity (CBD), States have agreed to establish networks of Marine Protected Areas (MPAs), and that representativity is a necessary feature of the networks. 2. There is extensive literature on the intent of these commitments and scientific guidance on network design. The guidance specifies that to have representativity captured in a network requires that a suitable biogeographical classification exists and that areas which represent the biogeographical subdivisions are included. However, no operational guidance has been provided on how to determine that a subdivision is adequately represented by a protected area. 3. This paper looks at the management and conservation functions expected to be served by representative MPAs, including an insurance policy function, a benchmark or natural control function, and a seed stock function. 4. The scales at which marine ecological processes typically operate are reviewed, as a basis for determining the scales of MPAs needed to provide these functions. 5. It is concluded that representative MPAs at the spatial scales of the interactions of key top predators and forage fish generally should ensure spatial scales large enough to give protection to the other processes as well. 6. To ensure the key functions are served, the representative MPAs also should have sufficient protection that human pressures do not alter the characteristics of these ecological processes.
